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.
Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae are endemic in New York City hospitals and have been associated with serious infections globally. A real-time polymerase chain reaction (RT-PCR) assay was developed to detect carbapenem resistance attributable to KPC from blood culture bottles positive for gram-negative bacilli. Culture confirmation of carbapenemase producti...

Background: Nail biting (NB) is a common, but unresolved, problem in psychiatry, psychology, medicine and dentistry. It is the habit of biting one’s nails, is commonly observed in both children and young adults Materials & Methods: The study was a comparative cross‐ sectional microbiological study, conducted on the saliva samples of 40 chronic nail biting subjects in that 20 were males and 20 w...
The in vitro antibacterial activity of four beta-lactam antibiotics (cefatrizine [BL-S640], cefamandole, cefoxitin, and carbenicillin) and three aminoglycosides (amikacin, gentamicin, and tobramycin) was determined against 197 strains of cephalothin-resistant Enterobacteriaceae. Eighty strains were found to be gentamicin-sensitive, and 117 were found to be gentamicin-resistant. Carbenicillin wa...
