ABSTRACT

The present study was carried out in 11 dairy herds in four municipal districts of the rural area of the State of Pernambuco, Brazil. Out of 984 quarter milk (246 cows), 10 (1.0%) were positive for clinical mastitis, 562 (57.1%) for subclinical mastitis and 412 (41.9%) were negative. A total of 81 Staphylococcus spp. isolates were obtained from milk samples from the cows diagnosed with subclinical mastitis. From these, 53 (65.0%) were S. aureus, 16 (20.0%) coagulase-positive staphylococci (CPS) and 12 (15.0%) coagulase-negative staphylococci (CNS). The isolates were further investigated for the presence of toxin genes by multiplex and uniplex PCR. The main gene observed was seg followed by seh, sei and sej. The distribution of these observed genes among the isolates obtained from different areas showed a regional pattern for the SEs. The presence of toxin genes in the strains isolated from bovine milk demonstrates a potential problem for public health.(AU)

Dos 984 quartos mamários examinados (246 vacas), 10 (1,0%) foram positivos para a mastite clínica, 562 (57,1%) para a mastite subclínica e 412 (41,9%) foram negativos para mastite. Foram isoladas 81 linhagens de Staphylococcus spp. do leite de vacas com mastite subclínica. Destes, 53 (65,0%) foram S. aureus, 16 (20,0%) estafilococos coagulase-positivo (SCP) e 12 (15,0%) estafilococos coagulase-negativo (SCN). O principal gene observado nos estafilococos foi o seg seguido pelo seh, sei e sej. Foi constatada distribuição regional dos genes dos estafilococos isolados dos animais nos municípios estudados. A presença dos genes das toxinas nas linhagens isoladas do leite de vacas representa risco potencial para a Saúde Pública.(AU)
