Health and production management strategies influence environmental impacts of dairies. The objective of this paper was to measure risk factors on health and production parameters on six organic and conventional bovine, caprine, and ovine dairy herds in southeastern Brazil over six consecutive years (2006?2011). The organic operations had lower milk production per animal (P≤0.05), lower calf mortality (P≤0.05), less incidence of mastitis (P≤0.05), fewer rates of spontaneous abortions (P≤0.05), and reduced ectoparasite loads (P≤0.05) compared to conventional herds and flocks. Organic herds, however, had greater prevalence of internal parasitism (P≤0.05) than conventional herds. In all management... |

RESUMO - Fatores associados à ocorrência da tuberculose bovina (TB), em dados de 209 fazendas, foram avaliados por meio de análise de variância. Os dados utilizados foram provenientes do levantamento epidemiológico por demanda, realizado nos rebanhos do estado do Rio de Janeiro, no período de 1959 até 1989. As variáveis significativas na análise bivariada foram incluídas no modelo e analisadas conjuntamente pelo método do modelo linear generalizado. A taxa de prevalência da TB nos rebanhos foi de 49,8%. As variáveis detectadas no estudo como as mais importantes para a ocorrência de TB foram: aleitamento (P=0,03) e as interações densidade x aleitamento (P=0,04) e produtividade x período (P=0,02). A importância da organização econômica da produção pecuária... |

The sequencing of the complete genome of Anaplasma marginale has enabled the identification of several genes that encode membrane proteins, thereby increasing the chances of identifying candidate immunogens. Little is known regarding the genetic variability of genes that encode membrane proteins in A. marginale isolates. The aim of the present study was to determine the degree of conservation of the predicted amino acid sequences of OMP1, OMP4, OMP5, OMP7, OMP8, OMP10, OMP14, OMP15, SODb, OPAG1, OPAG3, VirB3, VirB9-1, PepA, EF-Tu and AM854 proteins in a Brazilian isolate of A. marginale compared to other isolates. Hence, primers were used to amplify these genes: omp1, omp4, omp5, omp7, omp8, omp10, omp14, omp15, sodb, opag1, opag3, virb3, VirB9-1, pepA,... |

Anaplasma marginale is an important vector-borne rickettsia of ruminants in tropical and subtropical regions of the world. Immunization with purified outer membranes of this organism induces protection against acute anaplasmosis. Previous studies, with proteomic and genomic approach identified 21 proteins within the outer membrane immunogen in addition to previously characterized major surface protein1a-5 (MSP1a-5). Among the newly described proteins were VirB9, VirB10, and elongation factor-Tu (EF-Tu). VirB9, VirB10 are considered part of the type IV secretion system (TFSS), which mediates secretion or cell-to-cell transfer of macromolecules, proteins, or DNA-protein complexes in Gram-negative bacteria. EF-Tu can be located in the bacterial surface,... |

The study aimed to evaluate the risk factors associated with the frequency of IgG antibodies against Babesia bovis and B. bigemina in cattle in southern Mozambique. Eight hundred and nine serum samples were collected from cattle in three provinces namely Maputo, Gaza and Inhambane, and tested by indirect enzyme-linked immunosorbent assay (i-ELISA) to assess the humoral immune response towards B. bovis and B. bigemina. The chi-square test at 5% significance was used to determine whether there was an association between gender, age and geographic origin of seropositive animals. The overall prevalence was 78.8% (548/695) for B. bovis and 76.0% (528/695) for B. bigemina. The origin of the animals showed a significant association (p<0.05) with seropositivity... |
