1. Bacterial identification, somatic cell count, antimicrobial profile and toxigenic Staphylococcus strains search from mastitic cow milk samples on small farms properties
RESUMO: A mastite bovina impacta negativamente a produção leiteira e pode acarretar riscos à saúde pública. O presente estudo teve como objetivo a avaliação da qualidade do leite bovino proveniente de pequenas propriedades na região de Botucatu/SP. Foi realizada a contagem de células somáticas (CCS), identificação dos patógenos envolvidos nas ma

2. Frequency of microorganisms isolated at different stages of lactation and milk production loss associated with somatic cell count and to mastitis-causing pathogens
RESUMO O objetivo deste estudo foi avaliar a frequência de isolamento de agentes causadores de mastite subclínica em um rebanho e estimar as perdas de produção associadas com CCS>200.000 cél./mL. Três cultivos microbiológicos intervalados por sete dias foram realizados em todos os animais em lactação da propriedade avaliada, no período de junho a j

3. Impairments of mecA gene detection in bovine Staphylococcus spp.
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 bovi

4. Prevalence, aetiology and antibiotic resistance profiles of coagulase negative staphylococci isolated in a teaching hospital
In this paper we carried out a study about prevalence of the clinically significant coagulase negative staphylococcal (CNS) isolates found in an university hospital. Two hundred four CNS isolates from 191 patients obtained between the period of 1998 to 2002, were studied. About 27% (52/191) of the infection cases studied were confirmed as CNS-associated dise

5. Distribution of erm genes and low prevalence of inducible resistance to clindamycin among staphylococci isolates
INTRODUCTION: Resistance to macrolides, lincosamides and streptogramins B (MLS B antibiotics) in staphylococci may be due to modification in ribosomal target methylase encoded by erm genes. The expression of MLS B resistance lead to three phenotypes, namely constitutive resistance (cMLS B), inducible resistance (iMLS B), and resistance only to macrolides and

6. Detection of enterotoxin genes of Staphylococcus sp isolated from nasal cavities and hands of food handlers
Food handlers, an important factor in food quality, may contain bacteria that are able to cause foodborne disease. The present study aimed to research coagulase-negative (CNS) and -positive staphylococci (CPS) in 82 food handlers, analyzing nasal and hand swabs, with identification of 62 CNS (75.6%) and 20 CPS strains (24.4%). Staphylococcal enterotoxins gen

7. Bacterial biofilms with emphasis on coagulase-negative staphylococci
In addition to their capacity to attach to surfaces, various groups of microorganisms also produce an extracellular polymeric substance known as "slime". This slime forms a thin layer around cells known as biofilm. Thus, biofilm structure comprises bacterial cells and an extracellular polymeric substance. It also presents a defined architecture, providing th

8. Heterogeneous resistance to vancomycin and teicoplanin among Staphylococcus spp. isolated from bacteremia
This study evaluated the BHIA screening method with 4 or 6 mug/mL of vancomycin to detect glycopeptides heteroresistant staphylococci strains isolated from bacteremia. A total of 213 staphylococci strains were isolated from 106 patients between October/2001 and November/2002 in a tertiary hospital in Rio de Janeiro city. Fifty-seven (53.8%) patients presente

9. Slime production and antibiotic susceptibility in staphylococci isolated from clinical samples
A total of 187 isolates from several clinical specimens were identified to species level as 129 Staphylococcus aureus strains and 58 coagulase-negative staphylococci (CNS) strains by the API Staph System (Biomerieux). Slime production was detected both by the conventional Christensen's method as well as by the Congo red agar method. Seventy-two strains of st

10. Study of virulence factors in coagulase-negative staphylococci isolated from newborns
Coagulase-negative staphylococci (CNS) have been identified as the etiological agent in various infections and are currently the microorganisms most frequently isolated in nosocomial infections. However, little is known about the virulence factors produced by CNS that contribute to the pathogenesis of infections caused by these microorganisms. The study of C

11. Profile of antimicrobial resistance of bacteria isolated from cockroaches (Periplaneta americana) in a Brazilian health care institution
Cockroaches carry microorganisms to sterilized materials, equipment and non-contaminated food in hospitals and in homes. Hence, they are regarded as major microbial vectors. We isolated and identified microorganisms from living cockroaches captured from a Brazilian health care institution and we determined the antimicrobial susceptibility profile of the isol

12. Identification and enterotoxigenic potential of coagulase negative Staphylococcus spp. isolated from Brazilian industrialized salamis and microbiological quality of product. / Identificação e verificação do potencial enterotoxigenico de Staphylococcus spp.coagulase negativa isolados a partir de salames brasileiros industrializados e avaliação da qualidade microbiologica do produto.
Staphylococcus is ubiquitous distribution bacteria and present in skin of humans and other animals. However, staphylococci species can cause various diseases. Staphylococcal food poisoning is one of these diseases. But for meat industry staphylococci importance is not only because diseases. Some species are very important for the fermented sausage?s manufact
