In a precious report (Woolfrey et al., J Clin. Microbiol. 13:58-61, 1981), we indicated that the Repliscan system did not reliably identify Enterobacteriaceae. Recent improvements in the system prompted us to evaluate Repliscan II (Cathra International, Inc., St. Paul, Minn.) by using representative isolates of the population sample previously used to test the system. Isolates (692) representin...

OBJECTIVES The aims of this study were to determine the prevalence of extended-spectrum beta-lactamases (ESBLs) in AmpC-carrying Enterobacter spp. in a tertiary care university hospital in Vienna, Austria, and to implement a cost-effective strategy to detect ESBLs in this particular genus on a routine basis. METHODS Clinical Enterobacter isolates (n=208) were investigated by means of (i) an i...

The aim of this paper was to determine in 32 patients from 4 different Mexican hospitals the frequency of opportunistic bacteria in the 2010 to 2011 time period. The patients were divided in 4 groups. Group 1 included 21 HIV positive patients with acute respiratory syndrome. Four HIV positive patients with tuberculosis symptoms were included in Group 2; two patients with tuberculosis symptoms a...

BACKGROUND Cefotaxime plays an important role in the treatment of patients with bacteremia due to Enterobacteriaceae, although cefotaxime resistance is reported to be increasing in association with extended-spectrum β-lactamase (ESBL) and AmpC β-lactamase (AmpC). METHODS We conducted a case-control study in a Japanese university hospital between 2011 and 2012. We assessed the risk factors and...

results in general 438 urine isolates were obtained. e. coli was the most frequently occurring pathogen (54.80%), followed by klebsiella pneumoniae (16.0%), coagulase negative staphylococci (11.2%), enterobacter spp. (9.6%), proteus spp. 1.4% and p. aeruginosa (1.4%). resistance rates of e. coli isolates were 85.9% to co-trimoxazole, 80.0% to penicillin, 77.0% to ampicillin, 68.0% to chloramphe...

In a prospective, double-blind trial prophylactic cotrimoxazole produced a highly significant reduction in the incidence of bacteriuria after prostatectomy. Only two out of 38 patients who received the drug developed bacteriuria compared with 19 out of 36 patients on placebo. Klebsiella-Enterobacter spp and coagulase-negative staphylococci were responsible for most infections. Although co-trimo...

The in vitro activity of a new semisynthetic penicillin, piperacillin, was determined against 577 clinical isolates of gram-positive cocci and gram-negative bacilli. A concentration of 12.5 mug/ml inhibited 92% of isolates of Pseudomonas aeruginosa, 82% of Serratia marcescens, 73% of Escherichia coli, 61% of Klebsiella spp., and 42% of Enterobacter spp. Most Proteus spp. were extremely suscepti...

During this research 159 samples of ready-to-eat and precooked food were examined for the detection of Salmonella spp., Listeria monocytogenes, Escherichia coli, coagulase-positive staphylococci and Enterobacteriaceae, bacterial count. All samples were negative for Salmonella spp. and Listeria monocytogenes; although a low count of coagulase-positive staphylococci (no. 5 samples) and E. coli (n...

Since the first isolation in 2002, the metallo-β-lactamase GIM-1 has not been detected outside Germany. The data presented here, for 50 clinical blaGIM-1-positive isolates, including Pseudomonas spp. and Enterobacteriaceae (Enterobacter cloacae, Klebsiella oxytoca, Serratia marcescens, Escherichia coli, and Citrobacter freundii), collected between 2007 and 2012 at the original site in an ongoin...

Thienamycin, a new beta-lactam antibiotic, exhibited potent, broad-spectrum activity in vitro against gram-negative bacilli and gram-positive cocci, including many isolates resistant to currently available antibiotics. All isolates were inhibited at concentrations less than or equal to 25 mug/ml, with the exception of 12% of isolates of Enterobacter spp. and 3% of isolates of Serratia marcescen...
