Corynebacterium pseudotuberculosis is the causative agent of caseous lymphadenitis (CLA), a common disease in small ruminant populations across the globe. The following report describes two cases of a 3 year old Boer cross does showing large mass beneath the jaw, on the ventral side of the mandible with strong pain reaction to touch of the affected region. The consistency of the mass was non-movable, solid and hard on deep palpation. The mass was lanced and purulent discharges were evacuated. Phenotypic and biochemical identification methods allocated the isolates in C. pseudotuberculosis biovar ovis. The vast majority of the isolates was able to produce phospholipase D and was susceptible to most of the antimicrobial compounds tested. Furthermore, the isolates were compared with C. pseudotuberculosis isolated from other states with different geographical locations and showed high similarity index, suggesting the prevalence of dominant clones and a potential dissemination across the country.
This clinical case reports the diagnosis of left temporomandibular joint luxation in a Boer goat and the justification of culling due to welfare, practicality and cost efficient in the small ruminant industry. A one year-old female Boer goat weighing 15.5kg was presented with primary complaint of inappetance and losing weight. The most prominent abnormality observed was displacement of mandible to the right side. The goat was unable to open the jaw. The lower incisor teeth were also found to be misaligned. For the diagnostic work-up, the skull was radiographed in dorsoventral, left lateral and right lateral oblique views. The radiograph findings revealed loss of delineation of the normal caudal left mandible in dorsoventral and right lateral oblique views. Based on the physical examinations and x-ray findings, the goat was diagnosed to have luxation of left temporomandibular joint. Due to the poor growth performance of this goat, the farmer was advised to cull this animal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
