Successful treatment of carbapenemase producing Enterobacteriaceae peritonitis: 'Old therapy for a new bug'.

Multidrug-resistant organisms cause significant morbidity and mortality. Infections due to resistant gram-negative bacilli are increasingly being reported. For years, carbapenem antibiotics have been successfully used to treat infections due to resistant Enterobacteriaceae, such as and , including those producing extended spectrum β-lactamases, a subset of β-lactamase enzymes that confer broad resistance to penicillins and cephalosporins.

Evaluation of the BD Phoenix automated microbiology system for identification and antimicrobial susceptibility testing of Enterobacteriaceae.

We evaluated the accuracy of the BD Phoenix system for the identification (ID) and antimicrobial susceptibility testing (AST) of 251 isolates of the family Enterobacteriaceae representing 31 species. Organisms were inoculated onto the Phoenix panel according to the manufacturer's instructions. The results from conventional biochemical tests were used for the reference method for ID.

Leptotrichia buccalis bacteremia in two patients with acute myelogenous leukemia.

Leptotrichia buccalis is rarely implicated in systemic disease. We report two patients with clinically significant L. buccalis bacteremia which developed during the neutropenia secondary to chemotherapy.

Utility of extended blood culture incubation for isolation of Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, and Kingella organisms: a retrospective multicenter evaluation.

The incidence of and average time to detection for Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, and Kingella (HACEK) bacteria in blood cultures with standard incubation and the utility of extended incubation of blood culture bottles were reviewed at four tertiary care microbiology laboratories. HACEK organisms were isolated from 35 (<0.005%) of 59,203 positive blood cultures.
