A Rare Case of Infective Endocarditis Caused by .

is an alpha-hemolytic gram-positive catalase-negative coccus that typically causes urinary tract infections. It has been rarely implicated in other invasive infections such as endocarditis, bacteremia, peritonitis, meningitis, and vertebral osteomyelitis. There are approximately 50 reported cases of infective endocarditis in literature.

A case of meropenem-induced liver injury and jaundice.

This report describes what we believe is the first reported case of clinically significant cholestasis and acute liver injury within three days of meropenem therapy. An 83-year-old Hispanic female was admitted for sepsis of unknown origin and was started on intravenous meropenem.

Evolution of antimicrobial resistance among Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae in Brooklyn, NY.

Objectives: To document resistance patterns of three important nosocomial pathogens, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae, present in hospitals in Brooklyn, NY.

Methods: Susceptibility profiles of pathogens gathered during a surveillance study in 2006 were analysed and compared with similar surveys performed in 1999 and 2001. MICs were determined according to CLSI standards, and selected isolates were screened by PCR for the presence of VIM, IMP and KPC beta-lactamases.
