ABSTRACT A 6‐year‐old castrated male mixed breed dog presented to the “Louisiana State University Veterinary Teaching Hospital &‐anonymized for review” ophthalmology service with marked exophthalmos and lagophthalmos of left eye soft tissue swelling medial zygomatic arch. computed tomography (CT) scan was performed, it revealed a well‐marginated, lobulated, homogenously fat density involving retrobulbar space. Preliminary results fine‐needle aspirate (FNA) biopsy were not conclusive,...
ABSTRACT: This study described the epidemiological, clinical, pathological and bacteriological aspects of Mannheimia haemolytica pleuropneumonia in goats associated with shipping stress. Forty transported from Northeast to Southern region Brazil died during shipment, or 2-3 days after unloading. Clinical signs included dyspnea, mucopurulent nasal discharge, coughing. All were necropsied, multiple tissues collected for histopathological analysis involved agent identifications. lungs showed...
We determined the prevalence of diseases and pathogens associated with mortality in beef cattle State Rio Grande do Sul, Brazil, based on pathology laboratory submissions. Postmortem examinations were conducted 1,277 that died between 2008 2018. Information regarding age, time year, breed, regional location analyzed statistically. Most from surrounding region Porto Alegre, 78.7% cases had diagnostic value. The category most was infectious and/or parasitic (60%), followed by toxic...
ABSTRACT: Sow mortality is directly related to financial losses and productive efficiency in pig farms. Despite this, diseases associated with the death of sows are poorly understood. This study aimed determine main causes Brazilian To perform this research, three farms were visited, necropsies performed on all that had died spontaneously or subjected euthanasia. Tissue fragments collected for histopathological bacteriological examination. In addition, clinical signs, stage, parity, type...
This study aimed to characterize the cytologic, pathologic and immunohistochemical (IHC) aspects of feline giant-cell sarcoma.
Southern right whales Eubalaena australis (SRW) use the southern coast of Brazil as a wintering and calving ground. Other than anthropogenic threats, there is limited knowledge on health disease aspects for this species. We report gross microscopic findings microbiological identification streptococcal septicemia in SRW calf. Main included fibrinosuppurative omphalitis urachocystitis, suppurative cystitis, valvular endocarditis myocarditis, embolic pneumonia, myositis osteoarthritis,...
ABSTRACT: Obstructive urolithiasis is a disease characterized by the presence of uroliths in urinary tract, with consequent obstruction excretion pathways. This paper described epidemiological and clinical-pathological findings 22 outbreaks growing-finishing pigs Southern Brazil. All affected were male clinical presentation consisted lethargy, dysuria, rectal prolapse, abdominal distention, peripheral cyanosis reluctance to move. Clinical progression course ranged from 12 hours one week,...
ABSTRACT: Salmonellosis is a bacterial disease that affects several domestic animal species, and commonly diagnosed in cattle, horses, pigs. This study aimed to describe the epidemiological pathological findings of eleven cases enteric salmonellosis two with pulmonary involvement cattle Rio Grande do Sul State, Brazil. Clinical signs included fever, yellow diarrhea, sometimes blood streaks, dyspnea, clinical course ranging from 1 30 days. Eight occurred as outbreaks, whereas five...
Ocular involvement in systemic diseases is frequent cats; however, without concurrent clinical and ophthalmic examinations with gross and/or histologic analysis of the eye, these findings can be underdiagnosed. This article aims to provide gross, histologic, immunohistochemical characteristics ocular lesions from cats submitted necropsy, focusing on those caused by infectious agents. Cats that died due a disease were selected based necropsy diagnosis presence lesions. Gross, recorded. From...
This study aimed to evaluate the relationship between porcine circovirus type 3 (PCV3) viral load and histopathological findings in perinatal piglet tissues develop an immunohistochemical method for detecting virus lesions. The quantitative polymerase chain reaction (qPCR) cycle threshold (Ct) when amplifying PCV3 DNA area of perivascular inflammatory infiltrates different organs [central nervous system (CNS), lung, heart, liver, spleen, lymph nodes] were compared. To immunohistochemistry...
