This is the first description of a Trypanosoma vivax outbreak in state São Paulo (municipality Lins). Fever, jaundice, decreased milk production, weight loss, profuse diarrhea, abortion, anemia, leukocytosis and hyperfibrinogenemia were observed affected animals. Thirty-one cows calves died out total 1080 herd. Three showed neurological symptoms like dysmetria, ataxia, muscle weakness, ptyalism, lymph node enlargement submandibular edema. Flagellated hemoparasites blood smears. The species...
ABSTRACT Bartonella spp. comprise an ecologically successful group of microorganisms that infect erythrocytes and have adapted to different hosts, which include a wide range mammals, besides humans. Rodents are reservoirs about two-thirds described date; some them been implicated as causative agents human diseases. In our study, we performed molecular phylogenetic analyses infecting wild rodents from five Brazilian biomes. order characterize the genetic diversity spp., robust analysis based...
Abstract Infections by Trypanosoma vivax cause great losses to livestock in Africa and Central South Americas. Outbreaks due this parasite have been occurred with increasing frequency Brazil. Knowledge of changes caused byT. during the course disease can be diagnostic value. Thus, clinical signs, parasitemia, hematologic biochemical cattle experimentally infected hemoparasite were evaluated. Two distinct phases verified infection – an acute phase where circulating parasites seen then a...
Abstract Trypanosomiasis caused by Trypanosoma vivax has increased the reports in Brazil last decade. An outbreak is herein first reported state of Goiás, from May 2016 to January 2017. The start occurred city Ipameri (Goiás) after introduction 18 auctioned cows Minas Gerais. Direct parasitological test (blood smears) and polymerase chain reactions targeting catL genes diagnosed T. infection. Fifty six a herd 161 were infected; 12 died during 44 animals persistently positive (by blood even...
Abstract Livestock infections by Trypanosoma vivax have been occurring with increasing frequency, mainly due to the presence of animals subclinical and without apparent parasitaemia, making diagnosis challenging. The aim present study was evaluate several techniques used for T. in order assess best way using them during course disease. Molecular methods demonstrated higher rates detection than parasitological methods, detecting 33 54 (61.1%) known positive samples, while hematocrit...
ABSTRACT Parasitic otitis in cattle is normally caused by nematodes of the genus Rhabditis spp. and a common problem Gir breed. can cause premature culling even death animals. Despite its importance, there no effective standardized treatment protocol for this condition. The objective study was to evaluate two treatments parasitic cattle. external left ear animals washed with 2% boricated alcohol, while right received topical application Triclorfon, allantoin zinc oxide paste. were performed...
The transplacental transmission is the primary route of Neospora caninum infection in bovine herds around world. This study aimed to determine frequency parasite dairy cattle Agreste region Pernambuco through serological tests (IFAT and ELISA). Three hundred sixteen serum samples from cows heifers their offspring were analyzed. rate was 72.22% (13/18) for 69.23% (9/13) by IFAT. ELISA test showed 43.58% (17/39) 50% (9/18) heifers. rates similar, both groups test, but a higher seropositivity...
The objectives of this study were to describe occurrences Rhabditis spp. causing parasitic otitis in dairy cattle Gir breed the state Espírito Santo, southeastern Brazil, and evaluate biological control nematode using nematophagous fungi Duddingtonia flagrans (AC001) Monacrosporium thaumasium (NF34). After detection collection, three groups formed: two that treated, respectively, with fungal isolates; a group, without fungus. treatments as follows: (a) Petri dishes containing culture medium...
Abstract Trypanosoma vivax infections cause nonspecific clinical signs in cattle associated with aparasitemic intervals, making disease diagnosis a challenge. In Brazil, diminazene aceturate and isometamidium chloride (ISM) are available to treat bovine trypanosomosis. The objective of this study was follow-up, by molecular serological techniques, dairy naturally infected T. after ISM treatment. Thirty received two applications ISM, at dosage 1.0 mg/kg intramuscularly, on days 0 150. For...
Trypanosoma vivax is the most pathogenic ruminant’s hemoparasite, causing huge economic losses to producer when prevalent in herd. This study aims characterize trypanosomiasis naturally infected cattle order assess clinical findings, epidemiological risk factors and diagnosis of this disease outbreaks occurred states Pernambuco Alagoas, northeastern Brazil. For purpose, historical examinations, blood collection monitoring were performed 109 animals presenting illness for a period one...
Objetivou-se abordar o caso de um bezerro apresentando Perosomus acaudatus associado à atresia anal. Segundo proprietário, no primeiro manejo do foi verificada ausência da cauda e ânus, sendo realizada uma perfuração na região perineal. Ao ser atendido pela Clínica Ruminantes Hospital Veterinário Universitário Universidade Federal Santa Maria (HVU-UFSM) confirmada com presença ferida em cicatrização perineal depressão longitudinal dorsal pelve. Foi realizado exame radiográfico que revelou...
O carrapato Rhipicephalus (Boophilus) microplus é o principal ectoparasito de bovinos e esta associado à transmissão doenças, causando grandes prejuízos econômicos a indústria da pecuária no geral. surgimento populações carrapatos R.(B) resistentes aos carrapaticidas comerciais um problema observado em muitas propriedades rurais mundo, gerando prejuízo aproximadamente US$ 7 bilhões por ano. uso correto dos princípios ativos existentes conhecimento das diversas formas resistência do R. (B)...
Polioencefalomalacia e uma enfermidade metabolica, podendo ser definida como um conjunto de alteracoes na estrutura do sistema nervoso central, observadas macroscopicamente microscopicamente. A sintomatologia esta intimamente atrelada ao deficit energia produzida pelas celulas nervosas devido a falta tiamina ou mesmo outras causas o excesso enxofre, intoxicacao por chumbo sal privacao agua. O diagnostico pode realizado terapeuticamente. Ruminantes em confinamento sao os mais acometidos...
A dermatite digital (DD) é uma das principais doenças do sistema locomotor de bovinos que levam os animais à claudicação e causam graves prejuízos econômicos. Desde o seu primeiro relato na Itália, em 1974, a DD atingiu situação endêmica diversos países, incluindo Brasil. Bactérias gênero Treponema são agentes envolvidos, pois se apresentam como as bactérias mais abundantes também estão presentes nas partes profundas lesões. Mais 20 espécies diferentes foram identificados amostras DD, sendo...
Objective. The objective of this study was to evaluate the in vitro association fungus Duddingtonia flagrans (AC001) and ivermectin control gastrointestinal nematodes buffalo calves. Materials Methods. Four experimental groups were formed microtubes, with five replicates for each group: G1 (nematodes + AC001), G2 1%), G3 AC001 1%) G4 distilled water). For group, after 36 hours interaction, content microtubes read by optical microscopy, accounting number per group. Results. There a...
Trypanosoma vivax outbreaks have been reported with increasing frequency worldwide, causing significant economic losses in livestock. Though several studies suggested that cytokine responses may influence infection caused by sp., their exact role remains unclear and vary according to the animal species parasite strain. The present study aimed evaluate expression of peripheral blood cells from three Girolando dairy cows experimentally infected T. vivax. For this purpose, samples were...
O objetivo deste trabalho foi relatar um caso de mesotelioma peritoneal epitelioide papilar em bovino. Foi atendida uma vaca Gir, com dez anos idade, apresentando taquicardia, taquipneia, 8% desidratação, hipomotilidade ruminal, edema barbela e aumento da circunferência abdominal bilateral ventral. Os achados palpação consistiram na presença múltiplos nódulos abdominais firmes, tamanhos variados, localizados parede grande quantidade líquido intra-abdominal, confirmados pela ultrassonografia...
