Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary disorder in humans. Through a population study for G6PD deficiency using a cord blood quantitative G6PD assay in Bangkok, Thailand, we found that the prevalence of G6PD deficiency is 11.1% in Thai male (N=350) and 5.8% in female (N=172) cord blood samples. Among the neonates(More)
Infection caused by intestinal parasites is still a common health problem especially in children from developing countries. Orphans are a group of underprivileged population in society. To evaluate the intestinal parasitic infections in children in an orphanage in Pathum Thani province, Thailand, stool samples were collected during a cross-sectional study(More)
Lymphatic filariasis has been targeted by the World Health Organization (WHO) to be eliminated by the year 2020. In addition to chemotherapy and vector control, the control of reservoir hosts is necessary for the control program to succeed. Malayan filariasis, caused by Brugia malayi, is endemic in the South of Thailand where domestic cats serve as the(More)
OBJECTIVE Survey the prevalence of intestinal parasitic infections in 14 primary schools of Central Thailand. MATERIAL AND METHOD A cross sectional survey of the prevalence of intestinal parasitic infections in 14 primary schools of Central Thailand that included Ang Thong, Ayudthaya, and Suphanburi provinces was conducted One thousand and thirty seven(More)
Gnathostoma spinigerum infection is endemic in Thailand and many Asian countries. Current diagnosis is the skin test and enzyme-linked immunosorbent assay (ELISA) for IgG antibody against the G. spinigerum third-stage larvae (L3), but cross-reactivity is common. We evaluated the sensitivity and specificity of anti-G. spinigerum L3 IgG subclass antibodies(More)
The livers were separated from the viscera of 2738 swamp eels (Monopterus alba) purchased from Klong Toey market, the largest market in Bangkok, between June 1999 and May 2000. When these livers were digested in artificial gastric juice, 524 (19.1%) were found to be infected with the human-infective, third-stage larvae (L3) of Gnathostoma spp. All the(More)
Lymphatic filariasis has been targeted by the World Health Organization for elimination by the year 2020. Malayan filariasis, caused by Brugia malayi, is endemic in southern Thailand where domestic cats serve as a major reservoir host. However, in nature, domestic cats also carry B. pahangi infection. In addition to chemotherapy and vector control, control(More)
Filarial nematode parasites are a serious cause of morbidity in humans and animals. Identification of filarial infection using traditional morphologic criteria can be difficult and lead to misdiagnosis. We report on a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP)-based method to detect and differentiate a broad range of(More)
Infection caused by intestinal parasites is still a common health problem in a poor-hygiene population especially for children in developing countries. A cross-sectional study was conducted among 781 Karen students (age: 3 to 19, males: 325, females: 456) to determine the current status of intestinal parasitic infections in a mountainous area in the North(More)
Parasitic diseases are still considered to be a major public health problem. Most patients with parasitic infections are asymptomatic and therefore remain undetected. Asymptomatic parasitic infections are usually discovered by routine parasite examination. To determine the result of parasite examination at the Parasitology Unit, Out Patient Department, King(More)
