13. Caracterização fenotípica e genotípica de fatores de virulência e resistência à oxacilina em Staphylococcus spp. coagulase-positivos isolados de mastite bovina. / Phenotipic and genotipic characterization of virulence factors and oxacillin resistance in Staphylococcus spp. coagulase-positives isolated from bovine mastitis.
The present study was done to characterize phenotypic and genotypically the virulence factors and resistance profile to antibiotics, specifically to the oxacillin, of species of Staphylococcus spp. coagulase-positives isolated from milk samples of cows with mastitis. Of 150 isolated, the species S.aureus, S.intermedius and S.hyicus were identified. The antim

14. Caracterização Fenotípica da Resistência aos Antimicrobianos e Detecção do Gene mecA em Staphylococcus spp. coagulasenegativos Isolados de Amostras Animais e Humanas / Phenotypic Characterization of Antimicrobial Resistance and Detection of the mecA Gene in CoagulaseNegative Staphylococcus spp. Isolates of Animal and Human Samples
Coagulasenegative staphylococci (SCN) take part of normal microbiota. Although it has been considered saprophytic, nowadays there is a concern about its pathogenic potential.Nevertheless, all advance in SCN identification assays, these microorganisms are continually neglected in laboratorial routine of infectious diseases, because of the wide range of specie

15. Serogroups, K1 antigen, and antimicrobial resistance patterns of Aeromonas spp. strains isolated from different sources in Mexico
A total of 221 strains of Aeromonas species isolated in Mexico from clinical (161), environmental (40), and food (20) samples were identified using the automated system bioMérieux-Vitek®. Antisera for serogroups O1 to 044 were tested using the Shimada and Sakazaki scheme. The K1 antigen was examined using as antiserum the O7:K1C of Escherichia coli. Beside

16. 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

17. Resposta terapÃutica e inflamatÃria de ratos com infecÃÃo peritoneal submetidos ao uso tÃpico de Ampicilina/Sulbactam
A peritonite aguda representa uma importante causa de sepsis e Ãbito nas unidades de terapia intensiva e cirurgia. Classicamente o seu tratamento deve incluir: a administraÃÃo sistÃmica de antibiÃticos, a remoÃÃo mecÃnica dos XXII contaminantes e a restauraÃÃo da integridade gastrintestinal. A utilizaÃÃo de antibiÃticos diretamente na cavidade p

18. Risk Factors for Recovery of Ampicillin-Sulbactam-Resistant Escherichia coli in Hospitalized Patients
Ampicillin-sulbactam resistance in Escherichia coli is an emerging problem. This study determined risk factors for the recovery of ampicillin-sulbactam-resistant E. coli in hospitalized patients. A case-control design was used to compare two groups of case patients with control patients. The first group of case patients consisted of patients from whom nosoco

19. Pharmacodynamics of Ampicillin-Sulbactam in an In Vitro Infection Model against Escherichia coli Strains with Various Levels of Resistance
The activity of ampicillin-sulbactam against β-lactamase-producing Escherichia coli has been questioned. Therefore, in this study, the killing activity of ampicillin-sulbactam was investigated in an in vitro infection model which simulates human pharmacokinetics. One ampicillin-sensitive strain (E. coli ATCC 25922, ampicillin-sulbactam MIC = 4/2 μg/ml) and

20. Pharmacokinetics of Ampicillin and Sulbactam in Pediatric Patients
Intravenous ampicillin-sulbactam is effective in the treatment of various infections in adults, but little is known about the pharmacokinetics (PK) of ampicillin-sulbactam in children. The objective of this study was to determine the PK of ampicillin and sulbactam in pediatric patients with intra-abdominal infection, skin and/or skin structure infection, or

21. In vitro efficacy of sulbactam combined with ampicillin against anaerobic bacteria.
An ampicillin-sulbactam combination was compared with ampicillin alone, chloramphenicol, clindamycin, and metronidazole against 272 strains of anaerobic bacteria. Chloramphenicol and ampicillin-sulbactam were the most effective, inhibiting 98 to 99% of strains tested at breakpoint (16 micrograms/ml). The combination of sulbactam and ampicillin was much more

22. Proposed changes in interpretive criteria and potency of ampicillin and ampicillin-sulbactam disks for susceptibility tests.
The accuracy of disk susceptibility tests with ampicillin and ampicillin-sulbactam was not improved when the amount of ampicillin was increased from 10 to 20 or 30 micrograms per disk. For testing members of the family Enterobacteriaceae, ampicillin disk tests correlated better with broth microdilution tests when the zone size standards were altered from gre

23. Pharmacokinetics of ampicillin-sulbactam in healthy elderly and young volunteers.
The pharmacokinetics of ampicillin-sulbactam in elderly subjects (65 to 85 years; group 3, n = 8), compared with those in middle-aged (41 to 64 years; group 2, n = 8) and younger (20 to 40 years; group 1, n = 8) subjects, were investigated. A single 2-g dose of ampicillin combined with 1 g of sulbactam in 60 ml of intravenous solution was administered to eac

24. Optimal dilution susceptibility testing conditions, recommendations for MIC interpretation, and quality control guidelines for the ampicillin-sulbactam combination.
The ampicillin-sulbactam combination was evaluated in vitro to determine the optimal susceptibility testing conditions among five combination ratios and four fixed concentrations of sulbactam. The organisms tested were markedly resistant to aminopenicillins and most other beta-lactams. The ratio of 2:1 is recommended to assure recognition of the ampicillin-s
