A cross sectional study was performed to assess the epidemiological status of bovine tuberculosis in state Minas Gerais, Brazil, 2013. The divided into seven regions, and a preset number herds randomly sampled each region. From farm, female cattle aged 24 months or older were subjected comparative cervical tuberculin test (CCTT). Animals with inconclusive results re-tested same diagnostic procedure after minimum interval 60 days. total 31?832 animals tested from 2?182 farms. An questionnaire...
The practice of feeding dogs raw meat-based diets (RMBDs) is growing in several countries, and the risks associated with ingestion pathogenic antimicrobial-resistant Escherichia coli fed these are largely unknown. We characterized E. strains isolated from either an RMBD or a conventional dry feed, according to phylogroup, virulence genes, antimicrobial susceptibility profiles bacteria. Two hundred sixteen were isolated. Dogs RMBDs shed phylogroup E more frequently positive for heat-stable...
Abstract Blood samples and swabs from ocular conjunctiva mouth were obtained 64 cats. Of serum samples, 19 positive for Leishmania antibodies by ELISA (29.80%). Eight cats PCR (12.5%) in swab and/or mucosa. Poor kappa agreement between serological molecular results (k = 0.16) was obtained. From five one L. braziliensis four infantum. Phylogenetic analysis performed with the isolates of Leishmania, showed that infantum isolated phylogenetically close to those domestic dogs Brazil, while is...
Abstract In order to determine the prevalence of IgG against Trypanosoma vivax, Anaplasma marginale, and Babesia bovis in dairy cattle southern Minas Gerais, four hundred cows from 40 farms were randomly selected distributed 14 municipalities. Seroprevalence was determined by indirect immunofluorescence assay (IFA). Interviews conducted characterize producers production. Univariate analysis carried out using chi-square (x2) or Fisher's exact test. The multiple model constructed with...
Dogs are the main reservoir of Leishmania infantum in endemic regions. Canine leishmaniasis, caused by L. , can progress to a chronic disease resulting death. Vaccines have been developed with certain degree success. The pathogenesis this is not completely understood, especially previously vaccinated dogs. We herein described clinical data, parasite load, serum levels cytokines, and potential vdogs fucose‐mannose ligand (FML)/QuilA saponin vaccine (Leishmune™) naturally infected (Vi)...
In the Experimental Farm of Universidade Federal de Lavras (EF-UFLA), state Minas Gerais, Brazil, on their day birth, female Holstein calves were randomly selected and placed into two groups containing fifteen animals each: Strategic-Selective Treatment (S-ST) or Conventional (CT). S-ST, treated after coproparasitological examinations according to criteria established previously by researchers. Calves in CT opinion veterinarian EF-UFLA. For statistical analysis, frequency (%) fecal samples...
The aims of the present study were: to estimate seroprevalence Bluetongue vírus (BTV), bovine alphaherpesvirus 1 (BoHV-1), viral diarrhea virus (BVDV), Brucella abortus and Leptospira spp. in cattle from family farms North Minas Gerais; determine intercurrence association among these pathogens; assess possible associated factors seropositive herds animals. For this, 476 cows 46 were sampled evaluated serologically. was, respectively, for BTV 100% 52.0%, BoHV-1 95.7% 48.6%, BVDV 78.3% 46.1%,...
This work assessed the effectiveness and net operational costs of a strategic selective treatment for controlling ectoparasites (Rhipicephalus microplus, as well Dermatobia hominis Cochliomyia hominivorax larvae) hemoparasites (Anaplasma marginale Babesia spp.) in Holstein Friesian calves. Thirty calves were equally distributed two groups: ST) CT) conventional treatment. From birth, monitored biweekly until 12 months age. The CT group was subjected to parasite control according directions...
The chemotaxis of C. fetus subsp. venerealis and was determined in the presence bovine cervical mucus placental extract. Some reported substances ion those materials, such amino acids, ferrous iron, hormones, sugars organic acids were also investigated. Bovine mucus, placenta extracts some these materials namely L–fucose, L– aspartate, L–glutamate, L–serine, fumarate, pyruvate succinate chemoattractants. chemottraction significantly larger higher concentrations tested significant differences...
Background: Blue tongue (BT) is a noncontagious viral disease transmitted by hematophagous arthropods, especially of the genus Culicoides. The economic impact related not only to deaths in sheep herds but also possible correlation virus infection with development other diseases, such as pneumonia, abortion and movement problems. losses caused Tongue are linked restrictions on import export animals their genetic material reproductive disorders associated this disease. In addition, fact that...
