| Abstract |
Staphylococcus argenteus is similar to Staphylococcus aureus and may be misidentified as S. aureus or misidentified as Coagulase-negative staphylococci (CNS). However, in recent years, identification by mass spectrometry has become possible, and detection has become possible at our hospital. In this study, we analyzed 1,101 isolates of S. aureus and S. argenteus from patient materials between April 2019 and June 2020. S. argenterus was detected in 9 males and 11 females, and the age range was 1-96 years (median 79 years). Sputum was detected in 11 cases (50.0%), pus in 4 cases (18.2%), blood in 2 cases (9.1%), wound in 2 cases (9.1%), others in 3 cases (13.6%), and multiple materials in 2 cases. Drug susceptibility testing was performed in 16 cases, methicillin-sensitive: 15 cases (93.75%), resistant: 1 case (6.25%). Analysis of detection trends showed that there was no difference between sexes, but there were more cases detected in the elderly and in sputum and pus, suggesting a low rate of methicillin resistance. |
