| ABSTRACT The dichloromethane extract of Plectranthus ornatus Codd., a tradicional medicinal plant, showed antibiotic activity with minimum inhibitory concentration (MIC) values of 0.4 mg.mL-1 and 100 percent of biofilm inhibition against Staphylococcus aureus strains isolated from animals with mastitis infections. Based on these antibacterial activities, in addition to ethnopharmacological reports from healing men and farmers in Brazil, an herbal soap was produced from this active extract and was tested both in vitro and in vivo. In vivo assays conducted on these herbal soaps led to results similar to those previously conducted with the active extract. These results indicated the great potential of this plant for use as an excipient by preparing herbal... |

| Um total de 109 cepas de Staphylococci coagulase-negativa foi isolado de leite de vacas com mastite clínica e subclínica, em 35 fazendas, situadas em nove estados brasileiros, no período de fevereiro a maio de 2005. Os isolados foram investigados em relação a susceptibilidade in vitro a diversos agentes antimicrobianos. A resistência à penicilina foi a observação mais freqüente (93,5%), seguida por sulfonamida (88,9%), novobiocina (88,6%) e ampicilina (85,3%). Todas as cepas examinadas mostraram resistência a pelo menos uma das drogas antimicrobianas testadas. Cepas apresentando resistência múltipla foram extremamente comuns, com 10,0% dos microrganismos isolados apresentando resistência a todas as drogas antimicrobianas. Os resultados obtidos indicaram... |

| Biofilm formation is considered to be a selective advantage for Staphylococcus aureus mastitis isolates by facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and accumulation of cells in multilayers. The objective of this study was to determine the sensitivity and specificity of three techniques for the detection of S. aureus biofilm-positive strains. Two phenotypic tests, including growth on microtitre plates and Congo red agar, were compared with a PCR technique using 94 S. aureus strains obtained from cows with subclinical mastitis from two farms in the state of São Paulo. These strains were characterised by in vitro slime production on Congo red agar, biofilm formation on microtitre plates and... |

| A mastite representa um dos problemas mais sérios que afetam as fazendas de gado leiteiro. As mastites clínica e subclínica em bovinos, devido a leveduras, são causadas principalmente por espécies do gênero Candida. O objetivo deste trabalho foi identificar quais espécies dessa levedura estavam presentes em amostras de leite obtidas da glândula mamária de vacas apresentando mastite. Um total de 428 amostras de leite foi coletado nos estados de São Paulo, Paraná, Santa Catarina e Rio Grande do Sul. A identificação foi realizada por meio de critérios fenotípicos e fisiológicos. Foi possível isolar seis espécies de Candida em 55 (12,8%) das amostras. As espécies mais frequentes foram C. krusei(34,6%), C. parapsilosis(25,4%), C. tropicalis (18,2%) e C.... |

| Staphylococcus aureus antimicrobial resistance, especially to beta-lactams, favors treatment failures and its persistence in herd environment. This work aimed to develop a more specific primer for mecA gene detection based on the comparison of the conserved regions from distinct host origins and also investigated the presence of homologue mecA LGA251 in bovine strains. A total of 43 Staphylococcus spp. were included in this study, comprising 38 bovine S. aureus, two human and three equine coagulase-negative staphylococci (CNS). Phenotypical methicillin-resistance detection was performed through oxacillin agar-screening and cefoxitin disk-diffusion test. None isolate tested positive for mecA LGA251 gene. For mecA gene PCR, new primers were designed based on... |

| The present work is a large epidemiological study aiming to detect the prevalence of subclinical mastitis and to investigate the major udder pathogens in Jalisco State, western Mexico. For this purpose, 2205 dairy cows, representing 33 Mexican dairy herds, were involved. Of 2205 cows, 752 mastitic animals were diagnosed and only 2,979 milk samples could be obtained for further investigation. All 2979 milk samples were subjected to California Mastitis Test (CMT) to differentiate clinical cases from subclinical ones where 1996 samples (67 %) reacted positively. Of these, 1087 samples (54.5%) came from cows suffering from clinical cases of mastitis. Bacteriological identification of the causative agents revealed the presence of a major group of pathogens... |

| Few studies have been developed to evaluate the differences of bovine mastitis situation between hand and machine milking under the American tropic conditions. Twenty dairy herds were studied, 11 using hand milking (HM) and 9 machine milking (MM), from «San José de las Lajas» municipality, Mayabeque province. Between May 2009 and March 2012, samples from 182 cows (113 MM and 69 HM) were obtained meaning a 35.1% of total milking cows, resulting in 708 quarters sampled (435 MM and 273 HM). Samples were subjected to bacteriological diagnosis and somatic cell count (SCC). There were significant differences for the prevalence of blind quarters, subclinical mastitis and intramammary infections between hand milking, 1.1; 29.4 and 59.4% and machine milking, 3.8;... |
