ABSTRACT Bovine brucellosis (BB) is a compulsory notifiable bacterial disease caused by Brucella abortus, which responsible for severe reproductive disorders in cattle, considerable damages to trade and public health damage. The objectives of this study were identify the frequency BB analyze risk factors dairy herds Rio Branco microregion, state Acre, Brazil. Thus, 527-bovine-serological samples submitted buffered acidified antigen test 2-mercaptoethanol. Risk characterized administration...
RESUMO Leucose Enzoótica dos Bovinos (LEB) é uma retrovirose cosmopolita, que se alastra progressivamente pelos rebanhos determinando grandes prejuízos à bovinocultura brasileira. O objetivo deste estudo foi determinar a soroprevalência da LEB e investigar os fatores de risco associados soropositividade leiteiros criados na região Norte do Estado Tocantins. Para isso, 881 amostras séricas, colhidas 38 15 municípios norte Tocantins, foram examinadas pelo teste Imunodifusão Radial Dupla...
RESUMO Objetivou-se com este estudo avaliar a intercorrência entre leucose enzoótica e tuberculose em rebanhos bovinos leiteiros oito municípios do Estado de Pernambuco, pelo estabelecimento da prevalência reagentes às provas diagnósticas específicas. Foram analisados sorologicamente 662 animais, pela técnica imunodifusão dupla gel agarose 612 foram avaliados imunoalergicamente, por meio teste tuberculinização. Nos 15 examinados, as prevalências que apresentaram positividade aos testes IDGA...
The implications of bovine leukemia virus (BLV) on innate and adaptive immune responses have been widely investigated; however, the effects BLV mammary gland immunity require further investigation. present study investigated viability, phagocytic capacity, intracellular production reactive oxygen nitrogen species (RONS) by macrophages in milk samples from dairy cows naturally infected with or without persistent lymphocytosis (PL). No effect infection overall number per milliliter percentage...
Acreditou-se durante muito tempo que a espécie caprina era resistente à infecção por Mycobacterium bovis, porém tal hipótese foi desconsiderada quando relatos da enfermidade surgiram em vários países. No entanto, ainda permanecem desconhecidas certas características tuberculose caprinos e suas implicações na saúde pública caprinocultura nacional. Objetivou-se com este trabalho descrever os aspectos nosológicos, radiológicos, anátomo-histopatológicos, baciloscópicos biomoleculares leiteiros...
The aim of this study was to investigate the genetic context expanded-spectrum β-lactam resistance in a Klebsiella pneumoniae strain causing hard-to-treat nasal infection domestic cat. A K. isolate recovered from 4-year-old male cat hospitalised veterinary hospital Paraíba, Northeastern Brazil. Following phenotypic confirmation multidrug by disk diffusion method, genome sequenced using an Illumina MiSeq system. Multilocus sequence typing (MLST) and structural features related antimicrobial...
The periparturient period in dairy cows is marked by immunosuppression which increases the likelihood of infectious disorders, particularly also mastitis. An in-depth understanding peripartum leukocyte biology vital for implementation highly successful post-partum disease prevention measures. Immune checkpoint molecules, such as programmed death 1 (PD-1) and cytotoxic T-lymphocyte antigen 4 (CTLA-4), are critical inhibitory receptors expressed on immune cells, T that drive immunosuppressive...
An outbreak of esophagitis and ingluvitis caused by Salmonella Typhimurium in passerines seized from illegal wildlife trafficking is described. This activity causes stress leads to lowered immunity the birds. Additionally, inadequate hygiene conditions predispose birds diseases such as salmonellosis. Few studies report occurrence Salmonella-induced lesions esophagus crop wild birds; thus, this study aimed describe disease these species, investigate its presence environment, determine...

ABSTRACT: Enzootic bovine leukosis (EBL) is an infectious disease of cosmopolitan distribution and chronic character caused by a virus the Retroviridae family, leukemia (BLV). The epidemiological situation EBL in Brazil has motivated studies to improve its diagnosis, based on recommended serological techniques: agar gel immunodiffusion (AGID) enzyme-linked immunosorbent assay (ELISA). This study was designed evaluate use imported ELISA for detection BLV dairy herds raised Pernambuco, Brazil,...
RESUMO A dermatite alérgica à picada de ectoparasitos é uma enfermidade alergoparasitária bastante comum entre animais domésticos, sendo relatada principalmente em pequenos ruminantes e companhia. Contudo, a doença pouco diagnosticada na clínica equídeos devido similaridades nosológicas com outras dermatopatias. Objetivou-se, este relato caso, descrever síndrome clínica, o plano diagnóstico conduta terapêutica um muar acometido por essa enfermidade. Atendeu-se, no Hospital Veterinário da...
The present study sought to evaluate the expression of PD-1 and CTLA-4 in blood T lymphocytes during periparturient period their relationship with uterine health dairy cows, as determined by endometrial cytology serum concentrations β-hydroxybutyrate (BHB) non-esterified fatty acids (NEFAs), which are indicators a negative energy balance. second objective this was investigate whether is associated acute phase-protein haptoglobin concentration period. To address these objectives, 26...
Caseous lymphadenitis (CL), a contagious infectious disease caused by Corynebacterium pseudotuberculosis, stands out with great economic relevance for goat breeding in the country because it is one of main causes carcass condemnation and intense depreciation leather small ruminants. The objective was to carry descriptive study clinical epidemiological aspects CL goats state Pernambuco also evaluate detection C. pseudotuberculosis milk, blood, stool samples real-time PCR. Six hundred...
The objective was to determine the effects of LPS induced mastitis on systemic inflammatory response and early embryo development in lactating Holstein cows. Cows at 35 ± 7 DIM (n = 20) were submitted a modified Double-Ovsynch program (10 d interval between protocols with CIDR two PGF injections second protocol) timed AI (d0). randomly assigned (block design) treatments: 1) group- cows received an intrammamary infusions (d5 d10) 25 µg (strain 0111:B4) diluted 10 mL sterile saline morning...
