Pathogens transmitted by ticks are an emerging problem worldwide, this study aimed to diagnose the causal agents of infection in dogs presenting suspected hemoparasitoses. Fifty-eight with clinical signs such as depression, hemorrhagic diathesis and fever were evaluated regarding presentation, hemogram, blood smears serological tests, using indirect immunofluorescence method for Babesia vogeli Ehrlichia canis conventional PCR spp. (gene 18S rRNA), Rangelia vitalii rRNA) dsb). Five (8.6%) 58...
A dioctofimose é uma afecção pouco comum em cães, causada pelo Dioctophyma renale, que ocorre com maior frequência animais errantes. Quando um único rim parasitado, os pacientes podem não apresentar sinais clínicos devido à compensação contralateral. Não havendo terapia clínica efetiva para a dioctofimose, o tratamento indicado nefrotomia ou nefrectomia, na dependência da gravidade lesão. Foi atendido no Hospital Veterinário Universidade de Passo Fundo (UPF) canino, fêmea, castrado, sem raça...
Here we describe an outbreak of chorioptic mange in cattle, 56 years after its first identification Brazil. Between the months June and July 2011, dermatitis characterized by alopecia crusted thickened skin at insertion tail ischiorectal fossa was recognized 40 (35.7%) out 112 Holstein cows on a farm northeastern mesoregion state Rio Grande do Sul, After diagnosing caused Chorioptes bovis, were weighed treated with 0.5% ivermectin, as pour-on single dose, separated into two groups: early...
Toxoplasmosis, a disease caused by the intracellular coccidian Toxoplasma gondii that infects most warm-blooded vertebrates, is widely distributed and fatal for primates, which are peculiarly susceptible unknown reason(s). Owing to increasing number of Neotropical mammal deaths where in T. were detected analyzed tissues, present immunohistochemical study distribution patterns immunostainings related this parasite on primates necropsied at Laboratório de Patologia Animal Universidade Passo...
Haemonchosis affects sheep husbandry and its treatment is often compromised due to the development of anthelminthic resistance. Plant-derived bioactive compounds have been studied as alternative control Haemonchus contortus. The objective this study was evaluate effect Senecio brasiliensis extracts on H. contortus egg hatching infective larvae migration. aqueous extract from dried fresh plant alkaloid-enriched fraction previously leaves S. inhibited hatching. main compound in alkaloid...
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: Leptospirosis is considered the most widespread zoonosis worldwide, occurring more frequently in tropical and developing regions. The aim of present study was to detect presence Leptospira spp. different primate tissues, using immunohistochemical (IHC) assays, taking advantage considerable number necropsies compatible with a diagnosis leptospirosis neotropical primates at Animal Pathology Laboratory (APL) University Passo Fundo (UPF) northern region Rio Grande do Sul.Materials,...
This study describes changes in oxidative stress (OS) parameters mice experimentally infected with Angiostrongylus costaricensis, which causes abdominal angiostrongyliasis. For this, 28 Swiss were used, divided into two groups (G1 and G2), 14 animals each. Of these, eight ten infective larvae each, by gavage, six used as a control group. Mice from G1 G2 euthanized at days 24 post-infection, respectively. Tissue samples for histopathological analysis blood (serum) taken to assess the levels...
Resumo O macaco-prego (Sapajus nigritus) é um dos primatas que compõem a fauna silvestre do Rio Grande Sul. Assim como outros animais silvestres, os padecem de doenças infecciosas veiculadas por insetos, entre as quais, filarioses. Este relato apresenta aspectos anatomopatológicos uma infecção multissistêmica Dipetalonema spp. em macaco-prego, fêmea, adulta, origem silvestre, resgatado junto rodovia Norte Estado Sul pelo serviço policiamento rodoviário e conduzida para atendimento.

Abstract The capuchin monkey (Sapajus nigritus) is one of the primates that make up wild fauna Rio Grande do Sul. Like other animals, suffer from infectious diseases transmitted by insects, including filariasis. This report presents anatomopathological aspects a multisystemic infection Dipetalonema spp. in monkey, female, adult, origin, rescued along highway north state Sul road policing service and taken for assistance. In clinical evaluation, nystagmus involuntary head movements,...
Introdução: Angiostrongilíase Abdominal (AA), causada pelo nematódeo Angiostrongylus costaricensis, é considerada uma zoonose. A patogênese desta doença acontece em função dos vermes adultos habitarem as artérias mesentéricas do hospedeiro. Contudo, não apenas o intestino lesionado, outros órgãos acabam sofrendo com a presença parasito. Objetivo: Avaliar se houve alterações nas enzimas hepáticas e nos parâmetros de Estresse Oxidativo (EO), camundongos experimentalmente infectados A....
