Salmonella lamphun: first isolation of a new Salmonella serovar in Thailand.

Two isolates of a new Salmonella serovar, Salmonella Lamphun were discovered from animal feeds in Thailand, in 2003, which belongs to group C, with antigenic formula 6,8:y: 1,2. Both isolates were susceptible to all antimicrobials tested. The pulsed field gel electrophoresis pattern of both isolates comprises 11 DNA fractions sized 48, 65, 77, 105, 110, 170, 244, 330, 337,453 and 1,135 kbp.

Comparison of leptospiral serovars identification by serology and cultivation in northeastern region, Thailand.

Blood from patients suspected of leptospirosis 148 specimens were cultured for leptospira. Twenty two specimens were positive (15%). The isolated leptospira were tested against the 24 serovars of standard antisera by Microscopic Agglutination Test (MAT).

Distribution of Chlamydia trachomatis serovars among female prostitutes and non-prostitutes in Thailand, and non-prostitutes in Japan during the mid-90s.

The distribution of Chlamydia trachomatis serovars in Thailand and Japan during the same period of the mid-90s was determined. Seventy-one C . trachomatis specimens isolated from female patients who visited the Venereal Diseases Center at Bangkok, Thailand in 1994 were used in this study.

Occurrence of extended-spectrum beta-lactamase in clinical isolates of Klebsiella pneumoniae in a University Hospital, Thailand.

The occurrence and antimicrobial susceptibility of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae in patients attending Siriraj Hospital in Bangkok from August 2000 to January 2001 were determined. ESBL-producing isolates were screened with four different methods: disk diffusion according to the National Committee for Clinical Laboratory Standards (NCCLS) guidelines, Etest ESBL (CT/CTL and TZ/TZL), Oxoid combination discs and MIC Etest strip. Antimicrobial susceptibility testing were determined by a microdilution automatic method (VITEX system, bioMerieux).
