Strengthening public health laboratory capacity in Thailand for International Health Regulations (IHR) (2005).

Introduction: Thailand conducted a national laboratory assessment of core capacities related to the International Health Regulations (IHR) (2005), and thereby established a baseline to measure future progress. The assessment was limited to public laboratories found within the Thai Bureau of Quality and Safety of Food, National Institute of Health and regional medical science centres.

Methods: The World Health Organization (WHO) laboratory assessment tool was adapted to Thailand through a participatory approach.

Efficiency of a rapid test for detection of tetrodotoxin in puffer fish.

The selling and importing of puffer fish species and their products was banned in Thailand in 2002, because of possible neurotoxic effects. However, the sale of their flesh is still happening in Thai markets. Standard methods for toxin quantification (HPLC and LC-MS) have significant limitations, therefore a lateral flow, immuno-chromatographic test (TTX-IC) was developed as a tool for rapid detection of toxin.

Development of a 5-minute rapid test for detecting Vibrio cholerae O139.

Vibrio cholerae O139 is an etiology of cholera in Thailand. We determined to prepare a rapid test to detect V cholerae O139 using an immunochromatographic method to be used for surveillance and use in community laboratories. We conjugated murine monoclonal antibodies specific to the lipopolysaccharide of V.

Outbreak of norovirus gastroenteritis infection, Thailand.

Norovirus is a leading cause of gastrointestinal illness worldwide. We investigated an outbreak of gastrointestinal illness in Pattaya, Thailand, among participants of a course. We asked participants and family members to complete a questionnaire asking about symptoms, meals eaten, and foods consumed during the course.

Human herpesvirus 6 (HHV-6) infection and exanthem subitum in Thailand.

Of 50 patients in Thailand suspected clinically of having exanthem, subitum, 31 (62%) were serodiagnosed as HHV-6 infection. Sixteen strains of HHV-6 from 31 patients (52%) whose antibody titers had converted during convalescence were isolated during the acute phase. The disease occurred in infants from 3 months to 1 year of age and most frequently at age 4-6 months.
