Enterobacteriaceae are an important cause of infections, and the infection recurred weeks after finishing the antibiotic cycle, which led to another hospitalisation. For this reason, we decided to initiate treatment with the recent antibiespecially in immunocompromised patients. The recent appearance of carbapenemase-producing enterobacteriaceae otic ceftazidime–avibactam (C–A) for 2 weeks at a...

The in-vitro activities of six newer cepl~alosporins against 459 recently isolated strains of Gram-negative bacilli were determined using an agar dilution method to establish minimum inhibitory concentrations (mics). The cephalosporins tested were cefotaxime, moxalactam,cefoperazone, ceftriaxone, cefsulodin and ceftazidio~e. The strains tested included Enterobacteriaceae, Pscudornorlas aerugims...

Killing rates of fluoroquinolones, beta-lactams, and vancomycin were compared against Enterobacteriaceae, Staphylococcus aureus, pneumococci, streptococci, and Enterococcus faecalis. The times required for fluoroquinolones to decrease viability by 3 log(10) were 1.5 h for Enterobacteriaceae, 4 to 6 h for staphylococci, and >/=6 h for streptococci and enterococci. Thus, the rate of killing by fl...

We report on the evolution and epidemiology of carbapenem non-susceptible Enterobacteriaceae (CNSE) including carbapenemase-producing Enterobacteriaceae (CPE) in Belgium between January 2007 and April 2011. Significantly higher numbers of CNSE and of CPE were detected in 2010 and 2011 compared to the years 2007 to 2009. The majority of patients carrying CPE did not have history of travel abroad...

During January-June 2010, three Enterobacteriaceae isolates carrying a newly described resistance mechanism, the New Delhi metallo-beta-lactamase (NDM-1), were identified from three U.S. states at the CDC antimicrobial susceptibility laboratory. This is the first report of NDM-1 in the United States, and the first report of metallo-beta-lactamase carriage among Enterobacteriaceae in the United ...

The prevalence of carbapenem-resistant Enterobacteriaceae (CRE) infections is increasing in the United States. However, few studies have addressed their epidemiology in children. To phenotypically identify CRE isolates cultured from patients 1-17 years of age, we used antimicrobial susceptibilities of Enterobacteriaceae reported to 300 laboratories participating in The Surveillance Network-USA ...

Analysis of the cost of time and material required for the diagnosis of Enterobacteriacea isolates indicated that a conventional 17-tube (20-test) setup costs $7.98 per isolated identified. Using the API 20E, a similar identification cost $3.02. A conventional 7-tube (10-test) setup cost $3.60, whereas the comparable cost by 30% while increasing the number of isolate identified correctly by 3%....

One hundred strains of Enterobacteriaceae were examined in parallel with the API Rapid 20E and Micro-ID commercial four hour identification systems. With the API Rapid 20E system 78% of the strains were correctly identified, 15% were not identified, and 7% were misidentified. The respective figures with the Micro-ID system were 74%, 11%, and 15%.

The prevalence of members of the family Enterobacteriaceae in the intestines of seven species of iguanid lizards native to west-central Texas was determined. Of the 67 lizard specimens examined, 48.7% were infected with Salmonella and 9% were infected with Salmonella arizonae. Two lizard species (Sceloporus olivaceus and Crotaphytus collaris) were shown to have a 100% prevalence of Salmonella.
