Clinical and microbiological characteristics of community-acquired Staphylococcus lugdunensis infections in Southern Taiwan.
نویسندگان
چکیده
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.

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 کاملStaphylococcus lugdunensis; a pathogen that should be considered in Iran
Background: Staphylococcus lugdunensis is Gram-positive cocci of the staphylococcaceae family. S. lugdunensis despite having a clotting factor (wall coagulase), was classified in the coagulase negative staphylococcus group (CoNS) for lack of free coagulase. Although this bacterium is part of the human normal flora, in terms of virulence, S. lugdunensis is in second place after S. aureus. S. lug...
متن کاملFrom clinical microbiology to infection pathogenesis: how daring to be different works for Staphylococcus lugdunensis.
Staphylococcus lugdunensis has gained recognition as an atypically virulent pathogen with a unique microbiological and clinical profile. S. lugdunensis is coagulase negative due to the lack of production of secreted coagulase, but a membrane-bound form of the enzyme present in some isolates can result in misidentification of the organism as Staphylococcus aureus in the clinical microbiology lab...
متن کاملIncidence, characteristics, and outcomes of Staphylococcus lugdunensis bacteremia.
Of 63 patients with Staphylococcus lugdunensis bacteremia, 15 (23.8%) had clinically significant bacteremia, with an incidence of 1.3 cases per 100,000 admissions. Of the five patients with community-acquired S. lugdunensis bacteremia, three had endocarditis. Catheters were the most common portal of entry for health-care-associated or hospital-acquired bacteremia. Only one patient died of bacte...
متن کاملPrevalence of resistance and toxin genes in community-acquired and hospital-acquired methicillin-resistant Staphylococcus aureus clinical isolates
Objective(s): Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major health hazards and became of greater public health concern since the emergence of community-acquired MRSA. This work aimed to study the prevalence of mecA, femA, femB, lukS-PV, lukF-PV (PVL), intI, and intII genes among community-acquired (CA) hospital-acquired (HA) MRSA to increase vi...
