BACKGROUND: @entity8184 is one of the most common @entity12354 reported in Thai population of all age groups for which epidemiological information is important to understand patterns of transmission for developing methods ofprevention and control for each specific group. The authors aimed to study prevalence, incidence and riskfactors associated with @entity8184 in orphans and childcare workers. Additionally, subtypes ofBlastocystis were identified MATERIAL AND METHOD: A retrospective cohort study of Blastocystis sp. was conducted in orphans aged less than 5 years and their childcare workers at Babies' Home, Nonthaburi Province, Thailand. A base line survey was conducted in December 2009 and afollow-up survey was conducted in April 2010. A total of 336 and 331 stool samples were collected. @entity8184 was examined using short-term in vitro cultivation in Jones's medium supplemented with 10% fetal calf serum. To analyze subtypes ofBlastocystis sp., PCR-RFLP of the small subunit ribosomal RNA gene was performed. RESULTS: Theprevalence @entity281 in December 2009 and April 2010 were 8.1% and 13.3%, respectively The inlcidence rate @entity281 was 1.6/100 @entity1 -months. Subtype analysis ofBlastocystis sp. in December 2009 and in April 2010 showed that subtype 3 was the most predominant (76% and 76%), followed by subtype 1 (16% and 20%), and unidentified subtype (8% and 4%), respectively. Subtype 3 is of @entity1 origin, thus @entity1 -to- @entity1 transmission is considered a major @entity281 in this population. CONCLUSION: @entity1 -to- @entity1 transmission of @entity8184 in orphans living in the same house had been proposed, thus the prevalence and incidence of @entity8184 could be used to reflect the @entity558 in the orphanage. Infection prevention and control practice can be effectively implemented.
