Abstract The objective of the study was to report on a fatal case feline toxoplasmosis with coinfection leukemia virus (FeLV). A domestic cat (Felis silvestris catus) presented intense dyspnea and died three days later. In necropsy, lungs were firm, without collapse many white areas; moderate lymphadenomegaly splenomegaly also observed. histopathological examination showed severe necrotic interstitial bronchopneumonia mild hepatitis, associated intralesional cysts tachyzoites Toxoplasma...

To date, only a few studies have examined the impacts of feline leukemia virus (FeLV) subgroups on disease development in spontaneously infected cats. The present study identified FeLV-A and FeLV-B cats with lymphoma explored phylogenetic relationships env sequences. Twenty-six (n=16) or (n=10) were selected. FeLV p27 antigen positivity was determined using ELISA, proviral DNA blood samples detected nested PCR. Positive animals both tests classified as cases progressive infection subjected...

ABSTRACT: Knowledge about the causes of death in felines constitutes important information to owners, veterinarians, and researchers, aiming at reducing number deaths this species. In order determine main or euthanasia cats Santa Catarina plateau, data from 1995 2015 available necropsy files Laboratory Animal Pathology (LAPA) State University (UDESC) were collected evaluated. that period, 1,728 necropsied, mainly males (46.12%) adults (50.11%). The mean ages for kittens, adults, elderly 5.07...

Background: Feline leukemia virus (FeLV) is an important infectious agent in cats, responsible for great health damages and a large death amount. Among the most common clinical disorders caused by FeLV, severe hematological changes are related at progressive infection, ordinarily presented as cytopenias. Regarding its oncogenic potential, lymphoma observed illness originated agent. Therefore, this study has goal of describing comparing FeLV positive cats from selected population.Materials,...

Coccidiosis is an enteric disease caused by protozoa of the Eimeria genus and great economic relevance in industrial aviculture. The objective this work was to determine prevalence sp. broiler poultry houses with positive (System 1) negative 2) pressure ventilation assess associated factors. A transversal study conducted using 8 random chickens from 64 (n = 512) macroscopic histologic evaluation intestines, as well PCR for 90.6% (95% confidence interval [CI]: 97.8-83.5), 93.8% CI: 100-85.4)...

ABSTRACT: Proventricular dilatation disease (PDD) is a lethal and important of captive psittacine birds, affects wide range species, including endangered ones, lacks an effective treatment. This report describes PDD in three blue-and-gold macaws (Ara ararauna) southern Brazil. All originated from the same aviary presented similar clinical signs anorexia, apathy, emaciation prostration. At necropsy, one enlarged proventriculus. Histologically, lymphoplasmacytic infiltrates was observed...

The aim of this case report is to describe an uncommon hemorrhagic cerebrovascular accident (CVA) associated with osteosarcoma (OSA) metastasis.Cerebrovascular the acute onset a neurological deficit from any change in blood supply resulting pathological process, characterizing stroke and among all causes, neoplastic thrombus osteosarcoma, specifically, most infrequent clinical practice.A seven-year-old female midsize mixed-breed dog was submitted forelimb amputation for showing osteoblastic...

Background: The feline leukemia virus (FeLV) is clinically important retroviruses that infect domestic and wild worldwide, affecting more than 3 million cats representing a great risk for premature death. Some studies have demonstrated oxidative stress, as well the adenosinergic system, exert an role in pathogenesis of viral diseases. Oxidative stress considered disturbance antioxidant/oxidant status favor excessive generation or lower removal free radicals. Therefore, aim this study was to...

Parrot bornaviruses are responsible for proventricular dilatation disease (PDD) in psittacines. This study aimed to determine the occurrence and factors associated with infection psittacines kept captivity a state southern region of Brazil. A cross-sectional was carried out 192 birds from two facilities (A B) 2019, using choanal, esophageal, cloacal swabs feathers, totaling 768 samples subjected reverse-transcription polymerase chain reaction (RT-PCR), matrix (M) protein gene final product...

RESUMO A estenose esofágica benigna é uma afecção rara em pequenos animais, comumente secundária a esofagites ulcerativas. O refluxo gastroesofágico, frequente durante procedimentos anestésicos, principal causa de esofagite grave, com consequente formação cicatriz esofágica. presente trabalho tem por objetivo descrever dois casos ocorrentes após ovário-histerectomia, destaque para os diagnósticos realizados. Em ambos casos, combinação dos sinais clínicos sugestivos e achados esofagograma...

Cats are among the most common pets in world. The close relationship between human beings and cats supports importance of epidemiologic studies on feline diseases. Therefore, this study showed occurrence infectious diseases at Veterinary Clinics Hospital (HCV) Santa Catarina State University (UDESC), Lages (SC, Brazil), as well identifying major clinical signs presented each affection. Hence, 825 medical records were reviewed, from February 2013 to July 2015. Among reviewed records, 20/285...

This study determined the occurrence of parvovirus and distemper in dogs treated at Veterinary Clinics Hospital (HCV) Universidade Estadual de Santa Catarina (UDESC). For such, 3198 medical records filed HCV, from February 2013 to July 2015, were reviewed. From records, 145 (4.53%) diagnosed with (76 [2.38%]) or (69 [2.15%]). The most common clinical signs gastrointestinal [100%]), having hematochezia as commonly observed (74 [97.37%]); for distemper, neurological (48 [69.56%]) frequently...

Bone marrow (BM) evaluation is highly important for the diagnosis of numerous hematological alterations in animals, especially cats, given their greater propensity hematopoietic changes associated with retrovirus infections. This study aims to describe main aspects BM cats different conditions, comparing reference intervals established from animals without and also a previously interval. To do so, we evaluated full blood samples 120 no abnormalities on physical examination, negative FeLV...

Background: The eosinophilic bronchopneumopathy (EBP) is characterized by pulmonary infiltration with eosinophils. etiology of canine EBP remains unclear, although hypersensitivity to aeroallergens suspected. Dogs affected are usually young. persistent cough the most common clinical sign, often associated respiratory difficulty and exercise intolerance. diagnosis based on signalment, radiographic bronchoscopic findings, tissue eosiphilic demonstrated cytology bronchoalveolar lavage (BAL). No...

Idiopathic renal hematuria is diagnosed in situations where the cause of not clear, even after ruling out all possible differential diagnoses. A 14-year-old female Cocker Spaniel with continuous as only clinical sign for two months. Concomitant changes were ruled by blood tests, urinalysis, and abdominal ultrasonography. It was evidenced that originated from left kidney through ureteral catheterization diagnosis idiopathic determined excluding other causes hematuria. a rarely reported...

Background: Carcinomas are aggressive and invasive malignancies that originate from any type of epithelial cell responsible for many deaths in dogs. Carcinoma metastases occur primarily via the lymphatic route; however, they can by blood flow, thus reaching bone structures. In dogs, metastasis mammary squamous carcinomas to skeletal system is poorly described. The aim this study was report two cases dogs developed vertebral column.Cases: Case 1. A 10 years-old, male, mixed-breed dog with...
