Última Occurrence of Salmonella sp. and coagulase-positive staphylococci in raw eggs and Coalho cheese: comparative study between two cities of Brazil's northeast BJM Evêncio-Luz,L; Lima-Filho,J.V.; Evêncio-Neto,J.. Microbiological analyses of chicken eggs in Recife and Salvador have shown a high occurrence of Salmonella in the egg shells and yolks. Likewise, the occurrence of Salmonella plus coagulase-positive staphylococci in Coalho cheese reached alarming levels. The data revealed a significant risk of infections and intoxications from consuming these foods in the cities.

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.

Bras. Med. Vet. Zootec. Rapini,L.S.; Teixeira,J.P.; Martins,N. E.; Cerqueira,M.M.O.P.; Souza,M.R.; Penna,C.F.A.M.. 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.

Abstract Introduction There is a mechanism of macrolide resistance in Staphylococcus spp. which also affects the lincosamides and type B streptogramins characterizing the so-called MLSB resistance, whose expression can be constitutive (cMLSB) or inducible (iMLSB) and is encoded mainly by ermA and ermC genes. The cMLSB resistance is easily detected by susceptibility testing used in the laboratory routine, but iMLSB resistance is not. Therapy with clindamycin in cases of infection with isolated iMLSB resistance may fail. Objective To characterize the phenotypic (occurrence of cMLSB and iMLSB phenotypes) and molecular (occurrence of ermA and ermC genes) profiles of MLSB resistance of clinical isolates of susceptible and methicillin-resistant Staphylococcus...

Bras. Med. Vet. Zootec. Rapini,L.S.; Cerqueira,M.M.O.P.; Carmo,L.S.; Veras,J.F.; Souza,M.R.. 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).

The presence of yeasts and staphylococci in the oral cavity is important because they can act as supplementary microbiota and in certain situations can cause oral or systemic diseases. The aim of this work was to study the prevalence of Candida spp. and Staphylococcus spp. in the human oral cavity. Oral rinses were collected from sixty-eight individuals according to the technique described by Samaranayake and MacFarlane and then cultured on Sabouraud medium supplemented with chloramphenicol and Baird-Parker agar. After the incubation period, the microorganisms were isolated and identified through biochemical tests. The data obtained were statistically analysed by ANOVA. Candida spp. were isolated from 61.76% of the examined individuals and C. albicans was...

Venom. Anim. Toxins incl. Trop. Dis. Marconi,C.; Cunha,M. L. R. S.; Araújo Jr,J. P.; Rugolo,L. M. S. S.. Coagulase-negative staphylococci (CNS), components of the normal flora of neonates, have emerged as important opportunistic pathogens of nosocomial infections that occur in neonatal intensive care units. Some authors have reported the ability of some CNS strains, particularly Staphylococcus epidermidis, to produce a toxin similar to S. aureus delta toxin. This toxin is an exoprotein that has a detergent action on the membranes of various cell types resulting in rapid cell lysis. The objectives of the present study were to standardize the Polymerase Chain Reaction (PCR) technique for the detection of the gene responsible for the production of delta toxin (hld gene) in staphylococcal species isolated from catheters and blood cultures obtained from neonates,...

ABSTRACT: The genus Staphylococcus comprises some of the most important pathogenic bacteria for both humans and animals. It is responsible for bovine mastitis and canine otitis, besides being present in the microbiota of animals and as a contaminant in food. Its pathogenesis is related to the formation of capsule and biofilm, which contribute to its infectivity. The objective of this study was to observe the production of slime layer and formation of biofilm, which are related to the resistance to antimicrobial agents and presence of icaA and icaD genes, in 41 isolates of Staphylococcus spp. from different origins, provided by the Universidade Federal de Pelotas (UFPEL), Laboratório Regional de Diagnóstico (LRD). Strains of Staphylococcus spp. were... Tipo: Info:eu-repo/semantics/article Palavras-chave: Staphylococcus; Biofilm; Slime layer.

Ferreira dos; Cortelli,José Roberto; Jorge,Antonio Olavo Cardoso. Staphylococcus spp are not usually isolated from the oral cavity, and when this occurs, they are considered to belong to the transitory microbiota. Individuals with periodontal disease represent possible reservoirs of these opportunistic bacteria in the oral cavity. The use of antibiotics for treatment of periodontal disease or other infections may predispose to the increase of the number of Staphylococcus spp. in the oral cavity. These microorganisms easily become resistant to antibiotics, and may result in superinfection. The purpose of this study was to evaluate the presence of Staphylococcus spp. in the oral cavity and in periodontal pockets of patients with chronic periodontitis, identify the isolates and verify the relationship between the presence...

Bras. Med. Vet. Zootec. Dias,R.S.; Carmo,L.S.; Heneine,L.G.D.; Rocha,P.H.; Barbosa,C.F.; Rodrigues,R.J.; Linardi,V.R.. 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.... Tipo: Info:eu-repo/semantics/report Palavras-chave: Mice; TSST-1; Acute toxicity (LD-50); Staphylococcus.

BACKGROUND: Usual treatment regimens with vancomycin often fail to provide adequate serum levels in patients with severe infections. METHODS: Retrospective analysis of vancomycin trough serum measurements. The following parameters were calculated by Bayesian analysis: vancomycin clearance, distribution volume, and peak estimated concentrations. The area under the concentration curve (AUC) (total daily dose/24 h clearance of vancomycin) was used to determine the effectiveness of treatment through the ratio of AUC/minimum inhibitory concentration (MIC) above 400, using MIC = 1 µg/mL, based on isolates of Staphylococci in cultures. RESULTS: Sixty-one vancomycin trough measurements were analyzed in 31 patients. AUC/MIC > 400 was obtained in 34 out of 61...
