| 129 strains of Micrococcaceae were isolated from food of animal origin (minced meat, cakes with confectioner's custard) on Baird-Parker medium. 120 were Staphylococcus and 9 Micrococcus, according to the ID 32 STAPH-System (1989). The results were analyzed using a computer program. 60% of these 120 Staphylococcus strains of animal origin were coagulase positive S. aureus (aurease+, Rapidec Staph technique). 46% were resistant to novobiocin (5 microg/ml), 13 to 44% were identified with negative discordant tests using this micromethod. 44% produced no acetoin, 35% had no urease and 15% no arginine dihydrolase. 48 Staphylococcus strains (40%) were identified as human coagulase negative Staphylococcus species (strains: 39; species: 9) or as animal species... |

| The antimicrobial resistance profile of 45 Staphylococcus strains isolated from 10 samples of Brazilian type "coalho" cheese was evaluated against eight antibiotics used either in human or in veterinarian medicine. The tested antibiotics decreasing resistance degree was: penicillin (100.0%), tetracycline (91.0%), vancomycin (75.5%), gentamicin (71.1%), oxacillin (66.7%), erythromycin (60.0%), cephalothin (48.9%) and sulphazothrin (26.7%). The high frequency of Staphylococcus strains presenting resistance to the tested antibiotics, emphasizes the importance of the control of the abusive use of antibiotics by medical and veterinarian subjects. |

| Agruparam-se 167 cepas de Staphylococcus, isoladas de diferentes sítios (fossas nasais, orofaringe, palma das mãos e leitos subungueais), de dois manipuladores de queijos de leite de cabra, em pools (45), de acordo com a similaridade da espécie e o local de origem, e testou-se o seu potencial de produção de enterotoxinas (SE) A, B, C e D, e da toxina da síndrome do choque tóxico (TSST-1). Constatou-se que 62,2% dos pools foram capazes de produzir, de forma individual ou associada, SEA (33,3%); SEB (46,7%); SEC (8,9%); SED (4,4%) e TSST-1 (4,4%). Dos pools enterotoxigênicos, 96,4% corresponderam a espécies coagulase negativa (Staphylococcus epidermidis e Staphylococcus cohnii). A capacidade de produção de SE e de TSST-1 pelas cepas de Staphylococcus spp.... |

| Canastra cheese is produced from raw cow's milk, and it is made at the farmhouse level using artisanal procedures and natural starters. The aim of this work was to determine the main hygienic-sanitary indicators and enterotoxigenic staphylococcal strains present during the manufacturing of traditional cheese of Serra da Canastra region, Minas Gerais state, Brazil. Samples from 10 farms were studied, and they included: water employed in the process, raw milk, natural starters, cheese curd before salting and cheese after five days of ripening. All water samples exhibited faecal coliform contamination above the maximum acceptable value recommended by Brazilian standards. Pseudomonas aeruginosa and sulfite-reducing clostridia were also isolated from the water... |

| Acute toxicity test (LD-50) using toxic shock syndrome toxin (TSST-1) was tested in BALB/c, C57BL/6 and Swiss mice. Animals (n = 10) were intraperitoneally injected with TSST-1 (0.01-10.0µg/mouse) followed 4h later by potentiating dose of lipopolysaccharide (75.0µg of LPS - E. coli O111:B4) and cumulative mortality was recorded over 72h. Control animals received either TSST-1 or LPS alone. The data were submitted to qui-Square test and acute toxicity test was calculated by probit analysis (confidence limits expressed as µg toxin/kg). BALB/c mice was the most sensitive (20.0µg/kg, 95% confidence limits: 9.0-92.0) followed by C57BL/6 (38.5µg/kg, 95% confidence limits: 9.11- 401.6). Data from Swiss mice was not conclusive, indicating only low sensitivity.... |

| 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 streptogramins B (MS B). The iMLS B resistance is the most difficult to detect in the clinical laboratory. OBJECTIVE: This study investigated the expression of MLS B resistance and the prevalence of the erm genes among 152 clinical isolates of Staphylococcus aureus and coagulase-negative Staphylococcus (CNS) from Hospital de Clínicas de Porto Alegre. METHODS: Primary MLS B resistance was detected by... |

| The antibacterial potential of leaf's essential oil (EO) from Brazilian pepper tree (Schinus terebinthifolius Raddi) against staphylococcal isolates from dogs with otitis externa was evaluated. The minimum inhibitory concentration of EO ranged from 78.1 to 1,250 fg/mL. The oil was analyzed by GC and GC/MS and cytotoxicity tests were carried out with laboratory animals. |

| The population dynamics of Staphylococcus spp. was studied during the ripening of Canastra Minas cheese at three farms located in the State of Minas Gerais, Brazil. The presence of coagulase (coa), thermonuclease (nuc), and enterotoxin (sea, seb, sec, and sed) genes was investigated in Staphylococcus strains isolated during the 60-day cheese-ripening period. The presence of the staphylococcal enterotoxins A, C, and D was also investigated in the cheese samples. Cheese samples that were matured for 0, 7, 15, 30, and 45 days presented staphylococci counts from 10³ to 10(8)cfu/g. All isolates considered coagulase-positive by physiological tests had the coa gene. However, no association was observed between the results obtained with biochemical tests and those... |

| Antimicrobial therapy may cause changes in the resident oral microbiota, with the increase of opportunistic pathogens. The aim of this study was to compare the prevalence of Candida, Staphylococcus, Pseudomonas and Enterobacteriaceae in the oral cavity of fifty patients undergoing antibiotic therapy for pulmonary tuberculosis and systemically healthy controls. Oral rinsing and subgingival samples were obtained, plated in Sabouraud dextrose agar with chloramphenicol, mannitol agar and MacConkey agar, and incubated for 48 h at 37ºC. Candida spp. and coagulase-positive staphylococci were identified by phenotypic tests, C. dubliniensis, by multiplex PCR, and coagulase-negative staphylococci, Enterobacteriaceae and Pseudomonas spp., by the API systems. The... |
