Cattle tick fever (CTF) causes significant economic losses in the livestock sector. The pathogenic action of hemoparasites is associated with anemia, weight loss, abortion and reduced productivity, which result animal death. Programs to prevent CTF involve several procedures, including immunization, chemoprophylaxis use ectoparasiticides, together vector control environment. objective this study was report an acute outbreak a group 157 Hereford cattle from farm without presence vector, that...
Background: In various regions of Brazil, horses and cattle are considered the most susceptible animals to plant poisoning. The plants genus Senecio important in Rio Grande do Sul because they have active principle known as pyrrolizidine alkaloid. Its diagnosis is made through epidemiology, clinical signs histopathological analysis, either tissues obtained by biopsy or necropsy. objective this study was report characterize epidemiological, anatomopathological findings three cases natural...
ABSTRACT: Bovine paratuberculosis causes chronic, incurable diarrhea and weight loss, resulting in decreased cattle production. The disease is caused by Mycobacterium avium subsp. (MAP), an obligate intracellular mycobactin-dependent mycobacterium that replicates slowly the host has heightened environmental resistance. In countries where found damage been quantified, direct indirect economic losses are extremely high. Local epidemiological data of paramount importance for implementation...
Melanocytic tumors correspond to approximately for 4 7% of in dogs and up malignant tumours. Melanomas generally exhibit aggressive biological behavior. In humans, abundant tumor-infiltrating lymphocytes (TIL) can be considered a good prognostic factor. Research on TIL canine melanomas is scarce, date, there are no studies verify its association with established factors. Our study aimed evaluate the lymphocyte population melanocytic using immunohistochemical markers, relate this...
O carcinoma, tumor maligno, pode conter arranjos celulares em ninhos, cordões e/ou ilhas de células epiteliais, sendo invasivo, com elevado potencial metastático. As neoplasias podem ser oriundas alterações genéticas hereditárias ou até mesmo causas químicas, físicas (radiação) infecciosas, e se farão presentes todas as do organismo. Sendo geralmente diagnosticadas no post mortem, o aparecimento tumores bovinos não é considerado um achado corriqueiro, pois acredita-se que a maioria deles...
Background: Feline lymphoplasmacytic gingivostomatitis (FLPG) is an idiopathic, multifactorial and highly challenging condition, since the results of available treatments are partial transitory. A set lesions triggered by inflammatory reaction observed, sometimes with ulcerations in oral mucosa, leading to algia discomfort. Histopathological examination figures as definitive diagnostic tool, presenting distinct cellular elements. The present study aims report three cases FLPG, firstly...
A 1-month-old uncastrated Ile de France male sheep was diagnosed with an opening in the left interventricular septal. The malformation evidenced and confirmed through necropsy observations of systemic histological lesions related to congenital heart disease, especially liver, lungs, heart. Depending on severity defect, connection promoting free blood transit between two ventricles can be associated a series clinical signs culminating animal's death. etiology malformations ruminants...
This study describes the clinical and pathological picture of a disease followed by death in sheep raised for subsistence, characterized difficulty locomotion, sternal decubitus, severe dyspnea, opisthotonos, pedaling movements, death. The occurred February 2020 northern state Rio Grande do Sul, Brazil, due to consumption fruits Eugenia pyriformis ('uvaia'). All that became ill later died, resulting morbidity 68.75% mortality 100%. An autopsy revealed presence E. with or without seeds rumen,...
A two-year-old male bovine of Aberdeen Angus breed with anorexia, weight loss, and apathy was reported for necropsy, being diagnosed systemic tuberculosis tuberculoid meningitis lesions. Bovine observed confirmed through the necropsy granulomatous lesions, mainly in lungs regional lymph nodes; specific staining alcohol-acid resistant bacilli immunohistochemistry were also performed. It should be noted that is a zoonotic disease, mandatory notification, caused by Mycobacterium bovis. In most...
An outbreak of spontaneous intoxication by the pseudofruits japanese grape (Hovenia dulcis) was observed in a flock 270 sheep Rio Grande do Sul, Brazil, resulting death nine animals. The clinical picture characterized digestive, nervous, and respiratory alterations with progression to after 15 48 hours. main microscopic findings were hepatic necrosis, necrosis rumen abomasum mucosa, pulmonary edema atelectasis, kidney degeneration, cerebral spongiosis, vacuolization Purkinje neurons. Hovenia...
Background: Squamous cell carcinoma (SCC) is a common cutaneous neoplasm in horses, which mainly affects the external genitalia, oral cavity, and periocular region. The development of SCC metastases rare these animals, most occurrence marked local infiltration. Exposure to ultraviolet rays skin depigmentation are main etiological factors SCC. Definitive diagnosis performed through histological examination lesions. present report describes clinical, anatomopathological, immunohistochemical...
Introduction: Nimesulide is a potent anti-inflammatorywith rapid and long-lasting effects, but also with high riskof hepatotoxicity. Objective: This work aimed to preventnimesulide-induced hepatotoxicity through the associationof nimesulide hepatoprotective agent. Materials andMethods: First, we tested three agents:N-acetylcysteine, L-carnitine, Gingko biloba extract inan in vitro hepatic cell model. Both N-acetylcysteine G.biloba showed promisor results. We selected N-acetylcysteineto...
The aim of this study was to report a case vena cava thrombosis with secondary bronchopneumonia in two-year-old Holsten breed cow from the municipality Jacutinga, Rio Grande do Sul State, Brazil. Vena is disease affecting adult cattle fed on concentrate-based diets. It characterized by presence septic emboli bloodstream, which formed caudal thrombi that obliterate vascular lumen, causing tissue hypoxia. most common etiology ruminal acidosis, generating ruminitis and subsequent liver...
