Monitoring of drug resistant Staphylococcus aureus in People's Democratic Republic of Lao.

Abstract

Drug susceptibility of Staphylococcus aureus has been examined in the past 9 years to monitor the appearance of drug resistant strains especially methicillin resistant S. aureus (MRSA). The pattern of drug susceptibility has been relatively constant, but S. aureus is gradually becoming resistant to ampicillin. One MRSA was isolated in 1996 from the nasal vestibulum of a non-infected patient at Mahosot Hospital but not isolated thereafter. In 2001, 2 strains of MRSA which belonged to different clones were first isolated from the infection foci of patients. One was isolated from Setthathirath Hospital, where many Japanese staff have been dispatched since 2000. Careful monitoring and epidemiological studies of MRSA are recommended.

Antimicrobial use and resistance data in human and animal sectors in the Lao PDR: evidence to inform policy

“… 24 In 2002, the first two MRSA isolates from clinically infected patients were reported. 25 The first MRSA isolated from blood was identified at Mahosot Hospital in 2017, with 14 subsequent cases by December 2020 for the whole country. S. aureus from non-blood culture specimens during 2012 and 2014 was described in 2017 with Panton-Valentine leukocidin positivity reported in 56/96 (58%) of isolates.…”

“…The first isolation of MRSA ( mecA positive) in Laos was reported in 1997 from the nose of an inpatient, without signs of local infection, in a central Vientiane hospital 24. In 2002, the first two MRSA isolates from clinically infected patients were reported 25. The first MRSA isolated from blood was identified at Mahosot Hospital in 2017, with 14 subsequent cases by December 2020 for the whole country.…”
