In addition, the number of bacteria inoculated and the method of inoculation also play huge roles in virulence of any particular strain. Charles P.E., Piroth L., Desbiolles N., Lequeu C., Martin L., Portier H., Chavanet P. New model of ventilator-associated pneumonia in immunocompetent rabbits. As for mice, S. pneumoniae is not part of the nasopharyngeal microbial community under normal circumstances. Most domestic rabbits can easily live to be 8 years old, and many can live Bucks may discharge pus from the penis or have an enlarged testicle. Transmission of the pinworm occurs by ingesting contaminated food or water. In countries where pneumococcal vaccines are used, the prevalence of the aforementioned serotypes has dropped. Your veterinarian can perform laboratory tests to confirm the diagnosis of coccidiosis. Reducing stress (such as crowding) in young rabbits and feeding unlimited hay or straw help prevent the disease. Although adult tapeworm infections are rare in domestic rabbits, finding tapeworm larvae in rabbits is common. WebTularemia pneumonia follows either inhalation of contaminated aerosols or is secondary to bacterial spread from a local site and is a much more serious form of tularemia. Development of experimental respiratory infections in neutropenic rats with either penicillin-resistant Streptococcus pneumoniae or beta-lactamase-producing Haemophilus influenzae. McNeely T.B., Staub J.M., Rusk C.M., Blum M.J., Donnelly J.J. Antibody responses to capsular polysaccharide backbone and O-acetate side groups of Streptococcus pneumoniae type 9V in humans and rhesus macaques. The mouse is the most frequently encountered model of pneumococcal pneumonia. Proliferative enteropathy caused by Lawsonia intracellularis bacteria may cause diarrhea in recently weaned rabbits. Kuikka A., Syrjanen J., Renkonen O.V., Valtonen V.V. Streptococcus pneumoniae (known as pneumococcus) remains as the most common bacterial pathogen causing community-acquired lower respiratory tract infections and the leading cause of morbidity and mortality worldwide, contributing to more deaths than all other etiologies combined in 2016 (1.2 million deaths) [1,2,3,4]. Affected rabbits lack appetite and energy and may have a fever. sharing sensitive information, make sure youre on a federal Intestinal Diseases Rabbits fed a suitable diet and kept in a healthy environment can live as long as 10 to 12 years. The most common diseases of rabbits include digestive system problems, respiratory infections read more ). Kits should not be fostered to another doe because they will spread the infection. Possible causes include dental malocclusion, open water crocks, and damp bedding. Different capsular polysaccharides (and serotypes) are associated with different degrees of antiphagocytic activity and invasiveness [11,12]. If the area becomes infected, the hair should be clipped and antiseptic dusting powder applied. Diseases that can be Spread from Rabbits to People, Bacterial and Mycotic Diseases of Rabbits, Disorders Affecting Multiple Body Systems. Fur mites are also common on rabbits. From there, it spread through domestic and wild rabbit populations in continental Europe. Pasteurella bacteria are the usual culprits, but other bacteria may cause rhinitis. Ershler W.B., Hebert J.C., Blow A.J., Granter S.R., Lynch J. Copyright 2023 Merck & Co., Inc., Rahway, NJ, USA and its affiliates. A vaccine prepared from a myxomatosis virus has protected rabbits from infection, but it is not available in the USA. The age groups more vulnerable and with the highest rate of deaths are children younger than five years and adults older than 70 years [1]. Pharmacodynamic assessment of clarithromycin in a murine model of pneumococcal pneumonia. Infected rabbits usually sneeze and cough. Sore hocks, also called ulcerative pododermatitis, does not actually involve the hock (the ankle joint) but instead affects the sole of the hindfoot and, less commonly, the front paws. However, this correlation varies according to the animals phase of life. In a severe pneumonia baboon model, investigators confirm that S. pneumoniae is capable of invading the myocardium and induce cardiac injury with necroptosis and apoptosis, followed by cardiac scarring after antibiotic therapy [138]. Jones E.E., Alford P.L., Reingold A.L., Russell H., Keeling M.E., Broome C.V. Predisposition to invasive pneumococcal illness following parainfluenza type 3 virus infection in chimpanzees. To achieve infection, this procedure is carried out while the animal is under deep anesthesia, which suppresses gag and cough reflexes and allows inhalation. Bergeron Y., Ouellet N., Deslauriers A.M., Simard M., Olivier M., Bergeron M.G. Herbold W., Maus R., Hahn I., Ding N., Srivastava M., Christman J.W., Mack M., Reutershan J., Briles D.E., Paton J.C., et al. Finally, rat models are, in our opinion, also suitable to evaluate the pathogenesis of pneumococcal infections complications. Table legend. Diagnosis depends on history, signs, lesions, and detection of Clostridium bacteria. The adult worm lives in the large intestine. Following a disease outbreak, thorough disinfection and decontamination of the cage or hutch using either 1% peracetic acid or 3% bleach helps reduce the presence of bacteria. Hoover J.L., Lewandowski T.F., Mininger C.L., Singley C.M., Sucoloski S., Rittenhouse S.A. WebCumulative Survival Probability of Persistently Neutropenic Rabbits with Experimental Pseudomonas aeruginosa Pneumonia: Impact on Strains with Genetically Defined Rates and risk factors for recurrent pneumonia patients hospitalized with community-acquired pneumonia: Population-based prospective cohort study with 5 years of follow-up. Rabbit calicivirus disease, also known as viral hemorrhagic disease, is highly infectious in European rabbits (Oryctolagus). Supernatants obtained from bronchoalveolar lavage are usually used to measure ante e post-mortem inflammatory levels of studied biomarkers and to detect their concentration and activation in the lungs during pneumococcal pneumonia [82,84]. Cohen J.M., Khandavilli S., Camberlein E., Hyams C., Baxendale H.E., Brown J.S. Azoulay-Dupuis E., Rieux V., Muffat-Joly M., Bdos J.P., Valle E., Rivier C., Isturiz R., Carbon C., Moine P. Relationship between capsular type, penicillin susceptibility, and virulence of human Streptococcus pneumoniae isolates in mice. As mentioned earlier in the Mouse and pneumococcal strains section above, Swiss mice have been largely used in literature to build the neutropenic model. Previous experimental models challenged rats with sodium bisulfide (NaHS) that resulted in a reduction of sepsis-related lung and kidney injury, while the host defenses remained intact [82]. For this reason, colonization and infection need to be induced through experimental procedures. The direct intrabronchial infection method does not require surgical skills but can result technically difficult give the small size of the animal. The sample is then centrifuged to remove cellular debris. Ammonia solution (10%) can be used to disinfect cages or other equipment exposed to contaminated feces. As for the IN route, this model can be used to establish both infection [70] and colonization [71] depending on virulence of the strain or susceptibility of mice. Of note, in 1996, Iizawa and colleagues [71] elaborated a model in which nasopharyngeal carriage was achieved through the aerosol route and pneumonia was subsequently induced by airway obstruction caused by IT instillation of 20 L of 2% formalin. [(accessed on 24 May 2018)]; File T.M., Jr. Clinical implications and treatment of multiresistant Streptococcus pneumoniae pneumonia. Szentiks C.A., Kndgen S., Silinski S., Speck S., Leendertz F.H. The chronic ethanol intoxication model was created by a continuous ethanol administration [87]. Figure 5 Percentage of severe disease and mortality, by age strata. In the aerosol technique, the bacterial suspension is placed in a Venturi-type nebulizer driven by 10 L/min of 5% CO2 in either air or oxygen. The calicivirus is highly contagious and can be transmitted by direct contact with infected rabbits or indirectly by inanimate objects. hypogammaglobulinemia may be encountered. 8600 Rockville Pike Malignant lymphomas (tumors in the lymph nodes) are relatively common and may occur in rabbits less than 2 years old. Both models showed an increased susceptibility to pneumococcal pneumonia similar to what is seen in human subjects. Topical and injected antibiotics are also used. The position of the animal during instillation has shown little impact on delivery of the inoculum [64]. As the rabbit drinks, this skin may become wet and soggy, which leads to inflammation. Macroscopic lung tissue scores (A) and lung edema rates (LW/BW 10 3) (B) of rabbits Imidacloprid is a drug that kills adult fleas on contact; products containing this drug have been successfully used to treat rabbits infested with fleas. Escherichia coli bacteria can also cause diarrhea in rabbits; this disease is called colibacillosis. A technique similar to the one used for intrabronchial and intratracheal instillation also allows collection of bronchoalveolar lavage (BAL) to determine drug concentrations in the animals lung [13]. Calame W., Douwes-Idema A.E., van den Barselaar M.T., Mattie H. Contribution ofalveolar phagocytes to antibiotic efficacy in an experimental lung infection with Streptococcus pneumoniae. Swine models can be a result of a naturally developed pneumonia due to a porcine pathogen (Streptococcus suis), which cause a pneumonia similar to that occurring in humans.

Feasibility and Safety of Local Treatment with Recombinant Human Tissue Factor Pathway Inhibitor in a Rat Model of Streptococcus pneumoniae Pneumonia. Role of Inflammatory Risk Factors in the Pathogenesis of Streptococcus pneumoniae. The following are reportable diseases in rabbits: Rabbit calicivirus disease (viral hemorrhagic disease). Signs may include loss of appetite, depression, and weight loss. Sandgren A., Sjostrom K., Olsson-Liljequist B., Christensson B., Samuelsson A., Kronvall G., Henriques Normark B. The infection rate in an affected group is often close to 100% and the death rate is 60% to 90%. Idanpaan-Heikkila I.P., Simon M., Zopf D., Vullo T., Cahill P., Sokol K., Tuomanen E. Oligosaccharides interfere with the establishment and progression of experimental pneumococcal pneumonia. Age-associated inflammation and toll-like receptor dysfunction prime the lungs for pneumococcal pneumonia. The metal cannula is then used as a guide to advance polyethylene tubing, through which the inoculum is instilled (usually 20 L). With the lenses of translational science this narrative review attempted to summarize relevant preclinical data on rodents, rabbits, swine, and non-human primates challenged with pneumococcal pneumonia infection. Swine models (i.e., pigs) are used to replicate pneumonia infection due to its similarity with humans in terms of anatomy, genetics and physiology [114,115,116,117] (Table 3). WebRabbits fed a suitable diet and kept in a healthy environment can live as long as 10 to 12 years. We find that in one state aloneHawaiithree years of Covid-19 mortality is equivalent to influenza and pneumonia mortality in the three years preceding the Covid-19 pandemic. Swine as models in biomedical research and toxicology testing. Young rabbits of weaning age are most susceptible. The most common diseases of rabbits include digestive system problems, respiratory infections, and skin disorders. In the IN model, the bacterial suspension is applied into the nostrils through a pipette tip. The etiologic agent is Pasteurella multocida, a gram-negative, nonmotile coccobacillus. Feldmesser M., Casadevall A. Andisi V.F., Hinojosa C.A., De Jong A., Kuipers O.P., Orihuela C.J., Bijlsma J.J. Pneumococcal gene complex involved in resistance to extracellular oxidative stress. Peterson G.E., Silva S.S., Amantea S.L., Miorelli P., Sanches P., Kulczynski J., Roesch E., Fraga J.C. Some of these diseases can also be passed from rabbits to people ( see Diseases that can be Spread from Rabbits to People Diseases that can be Spread from Rabbits to People ). Adding copper sulfate to the diet of young rabbits may also help prevent enterotoxemia. Increased susceptibility of splenectomized rats to infection with Diplococcus pneumoniae. WebBelow are the 10 highest and 10 lowest pneumonia/influenza death rates per state. No effective treatment is available. Subsequent models developed a method of IB instillation of bacteria [100,101]. Tuvim M.J., Clement C.G., Huang E.S., Cote G.J., Evans S.E., Lei X., Deftos L.J., Gagel R.F., Dickey B.F. Deletion of the gene encoding calcitonin and calcitonin gene-related peptide does not affect the outcome of severe infection in mice. Your veterinarian may need to flush the tear ducts to treat dacryocystitis. Pasteurellosis can cause rhinitis (runny nose), pneumonia, abscesses (pus-filled sores), reproductive tract infections, head tilt, and blood infection. Anticoccidial drugs may be prescribed. Two types of infectious benign tumors, known as papillomas, occur infrequently in domestic rabbits. The main focus is on molecules against resistant strains of pneumococci, especially against strains of S. pneumoniae with different resistance patterns to penicillin [107,108]. official website and that any information you provide is encrypted Characterization of lung infection-induced TCR T cell phenotypes by CyTOF mass cytometry. We used the search terms pneumonia or pneumococcal pneumonia or Streptococcus pneumoniae, in combination with the terms mouse model, rat model, rabbit model, swine model, and monkey model and with the terms pathogenesis, treatment, prevention, sepsis, and their variations. Another advantage of NPH models is that they develop symptoms consistent with lower respiratory tract infection similar to what is seen in humans. Several authors have shown that some of the mechanisms underlying the variable response to pneumococcal infection in different age groups are due to modifications in inflammatory responses, such as delayed activation of inflammasome [42], delayed production of interleukin (IL)-1 and interferon (IFN) [43,44], increased production of chemokines [44], and Toll-like receptor dysfunction [29]. Aspiration pneumonia was reported as the underlying cause of death in 334,712 deaths or an average of 17,616 deaths per year (30.1% of the total aspiration pneumonia-associated deaths). Young rabbits are the age group most susceptible to hepatic coccidiosis. Diagnosis of pasteurellosis is based on signs and laboratory tests that detect the bacteria. The animal is intubated orotracheally with a metal cannula that is advanced generally into the left main bronchus. Ear mites are common in rabbits. Healthy rabbits do not have E coli in their digestive tracts. Effect of thymosin alpha one on specific antibody response and susceptibility to infection in young and aged mice. Pneumococci inoculated by IP administration allow researchers to assess for clinical parameters measured during the progression of the disease [109]. Penicillin-resistant pneumococcal strains and other resistant phenotypes have been established in rabbit models in order to evaluate efficacy of new antibiotics [18,101,105,106]. Guckian J.C. Coagulopathy in experimental sepsis with Streptococcus pneumoniae in rabbits: Effect of drug therapy and splenectomy. Moreover, penicillin-resistant pneumococcal strains and other resistant phenotypes have been established in the existing rat models in order to evaluate the efficacy of new antibiotics [78,83]. Some authors expose the trachea in order to visualize the position of a needle inserted through the mouth, allowing accurate administration of the bacteria without the need to incise the airways [61]. Certain antibioticsincluding lincomycin, clindamycin, and erythromycinseem to cause enterotoxemia in rabbits and should not be given orally. Imaging studies including chest radiograph, chest ultrasound, or chest tomography are confirmatory of the presence of pulmonary infiltrations that could be manifested as air bronchogram, areas of consolidation, and, on occasion, pleural effusion (Table 1). Rabbit as an animal model for experimental research. Langley J.M., Kellner J.D., Solomon N., Robinson J.L., Le Saux N., McDonald J., Ulloa-Gutierrez R., Tan B., Allen U., Dobson S., et al. Infection with serotypes 1, 2, and 3 typically leads to lobar pneumonia [18]. Generally, capsular serotypes 25 and 6B are highly virulent [12]. Upper respiratory disease (rhinitis) often occurs before pneumonia. Transmission is by direct contact. These sores usually are confined to the genital region, but the lips and eyelids may also be involved. 1. Treatment is difficult and may not completely get rid of the organism. It is highly contagious and is transmitted primarily by direct contact, although transmission by coughing or sneezing may also occur. Serotype 1 in particular carries a high risk of complications, such as empyema [19]. The source of infection was not determined. Rubins J.B., Charboneau D., Paton J.C., Mitchell T.J., Andrew P.W., Janoff E.N. Azoulay-Dupuis E., Valle E., Bedos J.P., Muffat-Joly M., Pocidalo J.J. Prophylactic and therapeutic activities of azithromycin in a mouse model of pneumococcal pneumonia. Treponematosis is treated with penicillin injections. Insects and ticks transmit the virus; therefore, insect control could be used as means of disease prevention. Pasteurella (Snuffles) If you suspect that your rabbit has heat exhaustion, dampen its ears with cool water and take it immediately to your veterinarian or an emergency clinic. WebIn a colony of rabbits the mortality rate can be very varied, usually being between 30% and 90%. Factors that contribute to the disease include recent dietary changes, too much or too little fiber in the diet, antibiotic treatment, environmental stress, and infection with other bacteria. Butorphanol Tramadol Siggins R.W., Melvan J.N., Welsh D.A., Bagby G.J., Nelson S., Zhang P. Alcohol suppresses the granulopoietic response to pulmonary Streptococcus pneumonia infection with enhancement of STAT3 signaling. If it occurs, you should promptly take your rabbit in for an examination. In particular, cultures of tracheal secretions, bronchoalveolar lavage (BAL), protected specimen brushes (PSB), and direct lung aspirates were compared with cultures of lung homogenates and with histological findings. This narrative review will focus on the characteristics of the different animal pneumococcal pneumonia models. Development of a model of low-inoculum Streptococcus pneumoniae intrapulmonary infection in infant rats. Digestive disorders in rabbits include both noninfectious disorders (for example, hairballs) and infectious diseases. Induction of neutropenia is achieved though IP injections with an immunosuppressant drug such as cyclophosphamide, with administration schemes that tend to show slight variations from author to author in terms of timing and dose. There is no treatment, but the infection appears to be self-limiting if susceptible rabbits are not continually introduced into the population. However, studies on causes and rates of mortality on rabbit farms during pre- and postweaning stages are limited. Fur mite infestations usually do not cause any signs unless the rabbit is weakened by age, illness, or stress. Wanke-Jellinek L., Keegan J.W., Dolan J.W., Lederer J.A. Derived from these experiments, swine models allow researchers to obtain data for biochemical measures, blood gas analysis, physiological variables, ventilatory settings, pre- and post-mortem cultures, blood and bronchoalveolar lavage samples for inflammatory markers, antibiotic pharmacokinetics/pharmacodynamics, and pathology analyses [119,120,121,122,123,124]. These parasites irritate the lining of the ear and cause fluid and thick brown crusts to build up, creating an ear canker. Infested rabbits scratch and shake their head and ears. Rats models are also generally used to measure the inoculum size. Abgueguen P., Azoulay-Dupuis E., Noel V., Moine P., Rieux V., Fantin B., Bedos J.P. Amoxicillin is effective against penicillin-resistant Streptococcus pneumonia strains in a mouse pneumonia model simulating human, pharmacokinetics. Swine models offer a wide range of standardized methodologies due to their size compared to other small animal models [115]. Community-Acquired Pneumonia Requiring Hospitalization among U.S. In severe cases, treatment is not successful. Once a blockage has occurred, the goals of treatment are to remove the obstruction, restore the digestive tracts balance, get the digestive system working properly again, and relieve dehydration and loss of appetite. Ganzinger U., Haslberger A. Pharmacokinetics of cephalosporins in normal and septicemic rabbits. The animals were euthanized on day 4, and survival and pulmonary histopathology were compared between groups. Some affected rabbits have a head tilt. human pneumococcal serotypes 8 and 6b) [114]. Musher D.M., Thorner A.R. The area often turns green if infected with Pseudomonas bacteria. Myxomatosis has a worldwide distribution. Received 2019 Aug 14; Accepted 2019 Aug 26. Other signs include discharge of pus from the nose, difficulty breathing, and coma. Sauve C., Azoulay-Dupuis E., Moine P., Darras-Joly C., Rieux V., Carbon C., Bdos J.P. Efficacies of cefotaxime and ceftriaxone in a mouse model of pneumonia induced by two penicillin- and cephalosporin-resistant strains of Streptococcus pneumoniae. However, most of even the oldest do survive (131). Your veterinarian can do tests to confirm the diagnosis. Proctor M., Manning P.J. Adding magnesium oxide to the diet at 0.25% also may be helpful. The disease is more common in first-litter does. According to us, swine models are best suited to evaluate ventilator-associated pneumonia. Additionally, NHPs models are appropriate to conduct interventional studies to assess the potential mechanisms by how therapies such as inhaled carbon monoxide may have a therapeutic potential for patients with acute respiratory distress syndrome (ARDS) [139,140,141]. Signs are gelatinous or mucus-covered droppings, loss of appetite, loss of energy, low body temperature, dehydration, rough coat, and often a bloated abdomen due to excess water in the stomach. Spence S. The Dutch-Belted rabbit: An alternative breed for developmental toxicity testing. Induction of pulmonary inflammation by components of the pneumococcal cell surface. Hand-rearing infected young may be attempted but is difficult. Roughage (hay or straw) should be fed during the treatment to help carry the hair fibers through the digestive tract and out with the feces. Longterm infection of the prostate is likely. The ears may droop. Invasive pneumococcal disease leads to activation and hyperreactivity of platelets. Fleas can affect rabbits and many other animals. The Piroth model mimicked lethal pneumococcal lobar pneumonia with subsequent parenchymal consolidations and bacteremia [101]. Many of these problems are caused by parasites, such as mites, that will require medication from your veterinarian. o [alopecia OR hair loss ], , DVM, PhD, DACLAM, Animal Resource Center Veterinary Services. If your pregnant doe becomes listless, loses weight, or seems depressed, you should contact your veterinarian promptly. Pneumonia is common in domestic rabbits. Richter S.S., Heilmann K.P., Dohrn C.L., Riahi F., Beekmann S.E., Doern G.V. Experimental Pseudomonas aeruginosa pneumonia: Evaluation of the associated inflammatory response. Hutch burn is caused by wet and dirty hutch floors, by bladder irritation from calcium deposits, or by constant urine dribbling because of poor bladder control. In rabbit colonies, 30% to 90% of apparently healthy rabbits may be carriers that show no signs of the disease. Fresh pineapple juice (which contains the digestive enzyme bromelain) and papaya (which contains the enzyme papain) may help break down the mucus holding the hairball together. The legacy of this great resource continues in the online and mobile app versions today. Typically, mice are used as pneumococcal pneumonia models at a young adult age, which ranges between 614 weeks. It is caused by protozoa (single-celled organisms). Finally, rabbit models are also suitable to study and evaluate pneumococcal sepsis. To facilitate distal migration of the inoculum to the alveoli, anesthetized animals are usually kept in supine position with their heads elevated at a 45-degree angle until anesthesia has waned [45]. Streptococcus pneumoniae has been linked to high rates of morbidity and mortality, especially in children under 2, immunocompromised individuals, and the elderly population. Conversely, serotypes 1, 4, and 5 rarely colonize the nasopharynx. In our opinion, research utilizing non-human primates (NHPs) for pneumococcal pneumonia is limited compared to other to other types of experimental models. The model is very advantageous to evaluate pharmacokinetic and efficacy of different drugs, which makes rabbit models unique tools for testing efficacy of compounds, even if they are not used so often for this purpose, especially respectful to mouse models [101,105,106,107]. WebTo keep your rabbit healthy and happy throughout their life, you need to understand your rabbits needs. Several routes can be used to achieve lung infectionintratracheal (IT), aerosol, intravenous (IV), intranasal (IN), direct intrabronchial (IBr), and intraperitoneal (IP). Chiavolini D., Pozzi G., Ricci S. Animal Models of Streptococcus pneumoniae Disease. Treponematosis is a venereal disease of rabbits caused by Treponema bacteria. Usual routes of inoculum in rat models are IT, intrabronchial (IB), or intrapulmonary (IPu). Providing a high-fiber diet, avoiding stress and obesity, enriching the environment with toys and items to chew, and combing the rabbit daily to remove loose hair help prevent this condition. Hoover J.L., Singley C.M., Elefante P., DeMarsh P., Zalacain M., Rittenhouse S. Reducing antibacterial development risk for GSK1322322 by exploring potential human dose regimens in nonclinical efficacy studies using immunocompetent rats. This disease does not cause death unless it occurs along with infection by another organism that causes intestinal disease. Enterotoxemia causes rapidly developing, severe diarrhea, primarily in rabbits 4 to 8 weeks old. Fur mites may cause mild skin irritation or inflammation in humans. Community-acquired pneumonia. The wound is then either closed with surgical glue or sutured [58,59,62,63]. has advantages in terms of feasibility due to cost, access, and availability.
