RESUMO
The medical record database of a veterinary teaching hospital was searched from 2000 through 2014 for records of client-owned rabbits with positive cultures from odontogenic abscesses. Data reviewed included sex, age, abscess location, sampling technique, previous antimicrobial treatments, microorganisms identified and antibiotic susceptibility of aerobic bacteria. Forty-eight client owned rabbits with one or more odontogenic abscesses and culture results were evaluated. One hundred and eighty-five isolates (52 aerobic, 133 anaerobic) were identified from 61 positive cultures from odontogenic abscesses. The most common aerobic bacterial isolates were Pseudomonas aeruginosa (14/52), Pasteurella species (10/52), Streptococcus species (8/52) and Staphylococcus species (7/52). The most common anaerobic bacterial isolates were Fusobacterium species (36/133), Peptostreptococcus species (27/133) and Bacteroides species (27/133). Mixed aerobic and anaerobic isolates were detected in 73.3 per cent of cultures and 50.8 per cent of the samples had greater than three isolates. P aeruginosa was susceptible to amikacin and gentamicin, had variable resistance to enrofloxacin, and resistance to chloramphenicol. Pasteurella species, Streptococcus species and Staphylococcus species isolates were susceptible to most antibiotics tested. The bacterial isolates from rabbit odontogenic abscesses are a mixture of aerobic and anaerobic Gram-positive and Gram-negative organisms and without culture and susceptibility testing, it is difficult to predict appropriate antimicrobial treatment.

Abscesses of odontogenic origin in guinea pigs pose a serious health problem and need to be treated with a combination of surgical and medical therapy. The aim of this prospective study was to describe the microbial flora of odontogenic abscesses associated with osteomyelitis in 24 pet guinea pigs, to perform antibiotic sensitivity testing, and to make recommendations for practitioners on the antibiotics of first choice. Inclusion criteria for the study included the animal being diagnosed with an odontogenic abscess which underwent surgery and was not pre-treated with an antibiotic. Inclusion criteria matched for 24 guinea pigs. Samples (pus, capsule and affected tooth/bone) for bacteriological examination were collected under sterile conditions during the surgical procedure. The most commonly isolated bacteria from abscesses of odontogenic origin were Bacteroides fragilis in 12.8 per cent (6/47) of cases, Pasteurella multocida in 10.6 per cent (5/47) and Peptostreptococcus anaerobius in 8.5 per cent (4/47). Aerobic bacterial species only were isolated in 29.2 per cent (7/24) of cases, anaerobic bacteria only were isolated in 33.3 per cent (8/24), and mixed infection with anaerobic and aerobic bacterial species was seen in 37.5 per cent (9/24). Aerobes (n=20) were sensitive to enrofloxacin and marbofloxacin in 100 per cent of samples, benzylpenicillin potassium (penicillin G, PNCG) in 90 per cent, cephalotin in 85 per cent, amoxicillin-clavulanate in 75 per cent, doxycycline in 70 per cent, gentamicin in 65 per cent and trimethoprim-sulfamethoxazole in 55 per cent. Anaerobes (n=27) were sensitive to amoxicillin-clavulanate in 100 per cent of cases, clindamycin in 96.3 per cent, metronidazole in 92.6 per cent, PNCG in 92.6 per cent and cephalotin in 74.1 per cent. As guinea pigs are strictly herbivorous animals, based on the results of this study the recommended antibiotic treatment for odontogenic abscesses is a combination of fluoroquinolones and metronidazole.

CASE DESCRIPTION A 22-year-old male gorilla (Gorilla gorilla gorilla) housed in a zoo was evaluated for signs of lethargy, head-holding, and cervical stiffness followed by development of neurologic abnormalities including signs of depression, lip droop, and tremors. CLINICAL FINDINGS Physical examination under general anesthesia revealed a tooth root abscess and suboptimal body condition. A CBC and serum biochemical analysis revealed mild anemia, neutrophilia and eosinopenia consistent with a stress leukogram, and signs consistent with dehydration. Subsequent CSF analysis revealed lymphocytic pleocytosis and markedly increased total protein concentration. TREATMENT AND OUTCOME Despite treatment with antimicrobials, steroids, and additional supportive care measures, the gorilla's condition progressed to an obtunded mentation with grand mal seizures over the course of 10 days. Therefore, the animal was euthanized and necropsy was performed. Multifocal areas of malacia and hemorrhage were scattered throughout the brain; on histologic examination, these areas consisted of necrosis and hemorrhage associated with mixed inflammation, vascular necrosis, and intralesional amoebic trophozoites. Tan foci were also present in the kidneys and pancreas. Immunohistochemical testing positively labeled free-living amoebae within the brain, kidneys, eyes, pancreas, heart, and pulmonary capillaries. Subsequent PCR assay of CSF and frozen kidney samples identified the organism as Balamuthia mandrillaris, confirming a diagnosis of amoebic meningoencephalitis. CLINICAL RELEVANCE Infection with B mandrillaris has been reported to account for 2.8% of captive gorilla deaths in North America over the past 19 years. Clinicians working with gorillas should have a high index of suspicion for this diagnosis when evaluating and treating animals with signs of centrally localized neurologic disease.

BACKGROUND: The accumulation of pus in the orbit originating from an infected dental root is classified as odontogenic intraorbital abscess. METHODS: Clinical, laboratory, and image evaluation of a non-human primate was performed. RESULTS: The patient was cured after surgical therapy. CONCLUSIONS: This represents the first report of an odontogenic periodontal abscess in Cebus apella.

Dental disease is prevalent in the captive degu (Octodon degus), yet little has been documented on the variety of disorders in this species. In this internet-based study, dental cases presented over a 7-year period were collated, analyzed, and grouped. Of the 137 total cases, the most common dental disorder of the degu was found to be molar malocclusion (42.3 %). Other disorders documented included enamel decoloration (13.1%), molar elodontoma (8.0%), enamel hypoplasia (6.6%), incisor tooth fracture (6.6%), incisor malocclusion (3.6%), oral abscess (2.2%), and impacted molar teeth (0.7%). Details of each condition, pathogenesis, and clinical signs are described. Age was found not to be a significant predictor of dental disease in the degu.

Some of the clinical problems most frequently seen in veterinary dentistry and their surgical solutions are discussed. Extraction of teeth, surgical repositioning of teeth, tooth transplant, oral abscesses of tooth origin, impaction of teeth, repair of maxillary canine oronasal fistula, and simple techniques for oral wiring are among the issues considered.
