Bovine herpesvirus type 5 (BHV-5) is an alphaherpesvirus associated with meningoencephalitis, a disease highly prevalent in South America. In this study, we investigated the distribution of BHV-5 DNA brains latently, experimentally infected calves by using PCR for glycoprotein B gene. Twelve inoculated intranasally Brazilian isolate were divided into two groups: group A (n = 4) euthanized 55 days postinoculation (p.i.) tissue collection; 8) submitted to dexamethasone administration at day 60...
The protozoan Toxoplasma gondii is a causative agent of toxoplasmosis, an important and widespread zoonotic disease. transmission this disease in humans includes ingestion sporulated oocysts present contaminated water or food. T. are widely distributed toxoplasmosis considered major food- waterborne pathogen worldwide, making drinking containing source contamination for people. In the first half 2018, unprecedented outbreak was reported city Santa Maria, southern Brazil. temporal spatial...
Abstract This study evaluated dynamics of antibodies in dogs treated for canine visceral leishmaniasis (CVL). Twenty-one naturally infected by Leishmania spp. were grouped based on the treatment protocol: G1 (n=4) received allopurinol; G2 (n=10) allopurinol with miltefosine; and G3 (n=7) allopurinol, miltefosine Leish-Tec® vaccine. The monitored monthly a period one year. To verify serum antibody titers, an indirect immunofluorescence reaction was performed. We found that from had lower...
ABSTRACT: Determined the seroprevalence and epidemiological profile of Toxoplasma gondii, Neospora spp. Leishmania infection in horses Alagoas, northeastern Brazil. Blood samples were collected from 376 equines (horses) rural areas six municipalities. The serum subjected to Indirect Immunofluorescence Assay (IFA) detect presence IgG antibodies anti-T. cut-off points for T. 1:64, 1:50 1:40, respectively. All horse owners answered an questionnaire. Among analyzed samples, 44.94% (169/376)...
ABSTRACT: This study aims to describe the molecular detection of Sarcocystis neurona, Toxoplasma gondii, and Neospora caninum in brain samples obtained from bovine fetuses at a slaughterhouse South Brazil. Brain 35 asymptomatic pregnant beef cows underwent nested polymerase chain reaction (PCR) amplify fragment 18S rRNA gene specific S. T. N. caninum. The amplicons were subjected two-step digestion process: first, with restriction enzyme DdeI, which differentiates gondii neurona;...
A infecção pelo Neospora caninum é distribuída mundialmente e tem sido considerada uma importante causa de abortos em bovinos, que são hospedeiros intermediários do protozoário. O presente artigo relata um estudo sorológico da N. 1.024 amostras ovinos bubalinos, oriundos 55 propriedades 16 municípios Estado Rio Grande Sul (RS). Anticorpos contra o agente foram detectados por teste imunoenzimático tipo ELISA 11,4% (89/781) das 14,6% (24/164) dos bubalinos 3,2% (2/62) ovinos. Bovinos...
Neospora spp. is a intracellular protozoan phylogenetically closely related to Toxoplasma gondii and Sarcocystis neurona, it can infect horses leading the development of reproductive or neurological diseases. We determined presence antibodies sp. in mares at their parturition time determine frequency vertical transmission healthy foals verify importance transplacental transmission. The samples were analyzed by indirect immunofluorescence antibody test, showing that seroprevalence higher than...
Protozoa from the family Sarcocystidae are agents of reproductive and neurological disorders in horses. The transmission these protozoa may occur via horizontal or vertical means, frequency potential later is not fully elucidated Thus, aim study was to correlation levels antibodies mares with pre colostral foals seropositive assess level distribution against Neospora spp., Sarcocystis neurona Toxoplasma gondii, at parturition. blood samples were collected immediately after parturition...
As lactonas macrocíclicas (LMs) (avermectinas e milbemicinas) são endectocidas amplamente utilizados em animais algumas parasitoses humanas. Em bovinos, a resistência parasitária às LMs é emergente, o surgimento de formulações que diferem nas suas propriedades farmacológicas tornou complexa escolha da droga mais indicada cada caso. Com objetivo avaliar possíveis alternativas para recuperar eficácia sobre cepas resistentes nematódeos gastrintestinais, testaram-se, neste estudo, dez diferentes...
Os principais fatores relacionados à ocorrência de surtos e doenças origem alimentar, estão às falhas múltiplas no controle qualidade na produção alimentos. Com o objetivo avaliar os impactos dos cursos capacitação em Boas Práticas Manipulação (BPM) para serviços alimentação Santa Maria, Rio Grande do Sul, realizado por profissionais estabelecimentos alimentares, instituições ensino habilitadas credenciadas. Foram visitados 41 que comercializam alimentos, com alvarás renovados ano 2014....
The excessive use of acaricidal products induces environmental and human contamination, whereas there is also the selection resistant tick's strains. Most chemical acaricides available in market have low efficacy due intensive inadequate management treatments. Thus, ecologically viable alternatives for control a promising area research. Herbal medicine has as fundamental issue study medicinal plants their treatment animal diseases. This experiment evaluated vitro Ocimum basilicum essential...
Bovine herpesvirus type 5 (BHV-5) is a major agent of meningoencephalitis in cattle and establishes latent infections mainly sensory nerve ganglia. The distribution BHV-5 DNA the brain rabbits prior to after virus reactivation was studied using nested PCR. Fifteen inoculated intranasally with were euthanized 60 days post-inoculation (group A, N = 8) or submitted dexamethasone treatment (2.6 mg kg-1 day-1, im, for days) later B, 7) tissue examination. Two groups BHV-1-infected (C, 3 D, 3)...
