The levels of cockroach allergen in relation to cockroach species and allergic diseases in Thai patients.

Recently, cockroaches have been established as the second most Important allergen, producing allergic diseases, especially in low socioeconomic populations. In Thailand, about 44-61% of atopic patients were positive to cockroach extract by a skin-prick test. This study examined cockroach allergen levels in relation to cockroach species and allergic diseases in the houses of cockroach-sensitive patients. Sixty households of allergic patients in the Bangkok metropolitan area were surveyed using open- and closed-ended questionnaires. Cockroaches were collected using commercial cockroach traps, while dust samples were obtained from the bedrooms, kitchens and living rooms of the houses using a vacuum cleaner. The cockroaches were counted and their species Identified. The levels of cockroach allergens were determined by specific monoclonal antibodies using a monoclonal antibody-polyclonal antibody based sandwich ELISA kit. Six cockroach species were Identified: Periplaneta americana (American cockroach, 72.15%), Supella longlpalpa (2.75%, found in only one house), Periplaneta brunnea (0.78%), Periplaneta australaslae (0.78%), Neostylopyga rhombifolla (0.78%), Blattella germanica (German cockroach, 0.39%) and nymphs (22.35%). Allergens of the predominant species, P. americana, were detectable in all homes studied, with the highest levels in the kitchen areas. The range of allergen levels in house dust varied from 0.40-162.00 microg per g of dust. The median and mean allergen levels in kitchen dust were 59.16 microg and 62.80 microg per g of dust, respectively, while the median allergen level in bedroom dust was only 15.90 microg per g of dust. The German cockroach allergen (Bla g 2) was undetectable in any of the houses. IN CONCLUSION: P. americana was the most common cockroach and may be the species causing allergic diseases, especially asthma, in Thailand, which differs from the USA and Europe

Cockroach surveys in the Northern region of Thailand and Guangxi Province of China.

Cockroach surveys were carried out in three provinces of the Northern region of Thailand: Chiang Mai, Chiang Rai, and Mae Hong Son, and three cities of Guangxi Province of the People's Republic of China: Nanning, Huangjiang, and Hechi. Sticky traps were used for cockroach sampling in these surveys. At least 30 houses in each province or city were randomly sampled. Traps were placed in kitchen areas for 2 nights. In Thailand, a total of 214 cockroaches was caught in 65 of 112 houses (59.4%) with an average of 1.9 cockroaches/ house. There were 5 species of cockroach caught: Periplaneta americana (32.7%), Pycnoscelis surinamensis (29%), Periplaneta australasiae (18.2%), Periplaneta brunnea (17.3%), and Periplaneta fuliginosa (2.8%). In China, a total of 198 cockroaches was caught in 67 of 99 houses (67.5%) with an average of 2 cockroaches/ house. There were 6 species of cockroaches caught: P. americana (53%), Py. surinamensis (12.6%), P. brunnea (12.1%), P. australasiae (12.1%), P. fuliginosa (9.6%), and Neostylopyga rhombifolia (0.6%). According to the surveys in this study, there were no significant differences among the number of cockroaches caught in the six locations of the two countries (p > 0.05). P. americana was the most abundant cockroach species in both countries.

Survey of indoor cockroaches in some dwellings in Bangkok.

This study aimed to investigate the species distribution of indoor cockroaches in dwellings in Bangkok. Commercial sticky traps were used to catch cockroaches in 128 private residences (40 single houses, 49 townhouses, 39 apartments), 34 offices, and 30 small groceries. The cockroaches were identified as Periplaneta americana, Supella longipalpa, Blattella germanica, Neostylopyga rhombifolia, P. brunnea, P. australasiae, Pycnoscelus surinamensis, and B. lituricallis; two were unidentified species. The most common species were P. americana, S. longipalpa and B. germanica--most of which were nymphal stages. P. americana and S. longipalpa infested all kinds of buildings, especially private residences (50.0% and 17.2%, respectively) and offices (61.8% and 58.8%, respectively); they were also found mostly (15.1%) in mixed infestation and with no predominant species. B. germanica (26.7%) were significantly predominant in groceries. Air conditioners have no influence on cockroach distribution.
