Última Risk of peritonitis during peritoneal dialysis in carriers of Staphylococcus aureus and coagulase-negative staphylococci J. Venom. Anim. Toxins incl. Trop. Dis. Batalha,J. E. N.; Caramori,J. C. T.; Corrente,J. E.; Montelli,A. C.; Barretti,P.; Cunha,M. L. R. S.. The presence of Staphylococcus aureus in the nasal cavities and pericatheter skin of peritoneal dialysis patients put them at high risk of developing peritonitis. However, it is not clear whether the presence of coagulase-negative staphylococci (CNS) in the nasal passages and skin of patients is related to subsequent occurrence of peritoneal infection. The aim of the present study was to verify the relationship between endogenous sources of S. aureus and CNS and occurrence of peritonitis in patients undergoing peritoneal dialysis. Thirty-two patients on peritoneal hemodialysis were observed for 18 months. Staphylococcus species present in their nasal passage, pericatheter skin and peritoneal effluent were identified and compared based on drug...

Venom. Anim. Toxins incl. Trop. Dis. Genaro,A.; Cunha,M. L. R. S.; Lopes,C. A. M.. Enterococcus faecalis is considered a pathogen responsible for hospital infections and, due to its frequent multi-resistant profile, has caused preoccupations among many medical authorities. The objective of this study was to determine the antimicrobial susceptibility of 74 strains isolated from blood cultures and purulent secretions to vancomycin and ciprofloxacin through the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) by using the Microdilution test. The results showed a greater efficacy of vancomycin compared to ciprofloxacin (98.6% of the strains were inhibited by vancomycin at lower concentrations: 0.06 - 1 µg/ml). However, in the MBC analysis 73% of the strains showed a MBC of vancomycin only at high...

Ano: 2005 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1678-91992005000300004 Standardization of the PCR technique for the detection of delta toxin in Staphylococcus spp. J. 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,...
