OBJECTIVE To describe antimicrobial resistance patterns for healthcare-associated infections (HAIs) reported to the National Healthcare Safety Network (NHSN) during 2009-2010. METHODS Central line-associated bloodstream infections, catheter-associated urinary tract infections, ventilator-associated pneumonia, and surgical site infections were included. Pooled mean proportions of isolates inte...

Lactic acid bacteria (LAB) such as Enterococcus spp. have an advantage over several because of their ability to easily adapt extreme conditions which include high temperatures, highly acidic or alkaline and toxic metals. Although many microorganisms been shown reduce selenite (SeO32?) elemental selenium (Se0), not much work has done on the combined effect In this study, aerobic batch reduction ...

Kolář M., J. Bardoň, I. vágnerová, P. Sauer, d. Koukalová, J. Petrželová, l. Čekanová, r. Pospíšil: resistance to antibiotics in Strains of Staphylococcus spp., Enterococcus spp. and Escherichia coli Isolated from rectal Swabs of Pigs. acta Vet Brno 2008, 77: 103-1100. The study aimed at determining the level of resistance of selected bacterial species (Staphylococcus spp., Enterococcus spp., E...

Mean pH values in pooled samples of foregut, midgut, and hindgut from adult Melanoplus sanguinipes, which had been raised in the laboratory on barley shoots and wheat bran, were 5.15, 6.39, and 5.98, respectively. Homogenates of midgut/hindgut sections and frass (feces) yielded colony counts of bacteria by the spread plate method of 5.7 to 5.9 and 5.3 to 5.5 log(10) colonies per mg, respectivel...

BACKGROUND & OBJECTIVES Enterococci are the leading cause of nosocomial infections, and are thus a persisting clinical problem globally. We undertook this study to determine the virulence factors and the antibiotic resistance in Enterococcus clinical isolates. METHODS One hundred and fifty Enterococcus isolates obtained from various clinical specimens were speciated biochemically and subjecte...

El objetivo de este estudio fue realizar una revisión la literatura sobre Enterococcus spp. resistente a antimicrobianos y cepas formadoras biofilme en queso coalho originario del Noreste Brasil. Se observó el impacto presencia bacterias enterocócicas sus efectos salud pública los consumidores tipo alimento. Sin embargo, se necesitan más estudios microbiológicos debido su importancia económica ...

The aim of the work was to collect, evaluate, summarize and compare heat resistance data reported for Campylobacter, Enterococcus, Escherichia, Listeria, Salmonella and Yersinia spp. The work was limited to resistance in liquids with pH values 6-8. Results obtained under similar experimental conditions were sought. Thermal destruction lines for the various bacterial groups studied were construc...

Pexiganan, a 22-amino-acid antimicrobial peptide, is an analog of the magainin peptides isolated from the skin of the African clawed frog. Pexiganan exhibited in vitro broad-spectrum antibacterial activity when it was tested against 3,109 clinical isolates of gram-positive and gram-negative, anaerobic and aerobic bacteria. The pexiganan MIC at which 90% of isolates are inhibited (MIC90) was 32 ...

An outbreak of occupational diseases involving 38 metal workers with local infections on the hands and the face (53%), bronchitis (29%), and bronchopneumonia (18%) urged an examination of 150 samples of emulsions which the workers used in processing metals. Among the isolated bacteria, the most frequent was Pseudomonas aeruginosa (48%), followed by Escherichia coli (44%), Proteus spp. (11%), En...

INTRODUCTION Knowledge of the microbiology of surgical infections after abdominal surgery can be of use when prescribing effective empirical antibiotic treatments. METHOD Analysis of surgical infections after abdominal surgery in patients enrolled in the Prevalence of Infections in Spanish Hospitals (EPINE) corresponding to the years 1999-2006. RESULTS During the period of the study, 2,280 ...
