Stenotrophomonas maltophilia

Stenotrophomonas maltophilia

an opportunistic ocular bacterial pathogen producing keratitis, keratopathy, and conjunctivitis; a gram-negative nonsporebearing rod, a major emerging nosocomial pathogen, it is of especial importance in intensive care units in part because of its resistance to most penicillins and also to cephalosporins and aminoglycosides. Formerly called Xanthomonas maltophilia and Pseudomonas maltophilia.

STENOTROPHOMONAS INFECTION OF THE LEG
A gram-negative, motile, strictly anaerobic bacillus of the family Pseudomonadaceae. It may cause pneumonia, meningitis, endocarditis, conjunctivitis, wound infections, and infections related to the use of central venous catheters. Trimethoprim-sulfamethoxazole is used to treat infections with this organism. This species was formerly called Pseudomonas maltophila and Xanthomonas maltophila. See: illustration

The in vitro activity of Xerava was compared to a variety of other antibiotics against a total of 15,887 Gram-negative and Gram-positive pathogens and showed that Xerava was more active than meropenem and piperacillin-tazobactam against methicillin-resistant Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, vancomycin-resistant enterococci, Stenotrophomonas maltophilia and Acinetobacter baumannii.
