Microbiological characteristics, presumptive identification, and antibiotic susceptibilities of Staphylococcus lugdunensis.
This study validated abbreviated methods for the presumptive identification of Staphylococcus lugdunensis and studied the antibiotic susceptibilities of 106 isolates. The combination of positive responses to ornithine and pyrrolidonyl arylamidase identified all S. lugdunensis isolates. Resistance to penicillin and methicillin was detected in 27 and 5% of isolates, respectively.
متن کاملClinical and microbiological characteristics of community-acquired Staphylococcus lugdunensis infections in Southern Taiwan.
Most Staphylococcus lugdunensis strains (49/59, 83%) were related to clinical infections, were susceptible to most antimicrobial agents with an overall oxacillin-resistant rate of 5% (3/58), and carried relatively great genetic diversity. Community-acquired infections (41/49, 84%) were dominant, often developed in patients with comorbidity, and had rather benign clinical courses without mortality.
متن کاملCadmium-resistance plasmid in Staphylococcus lugdunensis.
Plasmids that confer resistance to cadmium (MIC > or = 125 microM), were found in 18 out of 30 independent Staphylococcus lugdunensis strains from clinical specimens. Variants that were cured of their plasmid were cadmium sensitive. Restriction endonuclease sites of a 3.2-kb cadmium-resistance plasmid of S. lugdunensis, designated pLUG10, were similar to those of pOX6, a S. aureus cadmium-resis...
متن کاملThe Clinical Aspects of β-Lactam-Resistant Stenotro- phomonas maltophilia
Recent papers argue that major increases in the isolation of multidrug-resistant Gramnegative bacteria have been of some concern in clinical practice. Among these bacteria, Stenotrophomonas maltophilia is an intrinsic producer of β-lactamases, and has been recognized as a nosocomial pathogen. But few reports are available on the impact of the potential risk of mixed infections. The goal of this...
متن کاملβ-Lactam Resistance and Enterobacteriaceae, United States
Extended-spectrum cephalosporins (ESC) are an important drug class for treating severe Salmonella infections. We screened the human collection from the National Antimicrobial Resistance Monitoring System 2000 for ESC resistance mechanisms. Of non-Typhi Salmonella tested, 3.2% (44/1,378) contained blaCMY genes. Novel findings included blaCMY-positive Escherichia coli O157:H7 and a blaSHV-positiv...
