Item Human health importance zoonotic gastrointestinal helminths and ectoparasites among stray dogs in Galle District, Sri Lanka(Department of Biosystems Engineering of the Faculty of Agriculture & Plantation Management Wayamba University, 2021) Rathnayaka, S.; Gunathilaka, N.; Udayanga, L.BACKGROUND: A notably high stray and semi domesticated dog population exist in close proximity to humans in Sri Lanka. However, the prevalence of gastrointestinal and ecto-parasites among these stray dog population has been limitedly studied. Therefore, the present investigation focused on zoonotic potential among stray dog community in Sri Lanka. METHODS: A total of 110 stray dogs randomly captured from the Galle District of Sri Lanka during May to July 2018 was considered for the study. Freshly voided fecal samples were obtained. Ectoparasites were collected using a lose comb and stored in an alcohol solution. Presence of major gastrointestinal and ectoparasitic species were investigated using standard microscopic methods. The Chi-square test of independence was used for statistical analysis. RESULTS: The highest egg count as Eggs per Gram (EPG) were detected from A. caninum (264.65 + 86.02 EPG), followed by T. canis (58.38 + 7.22 EPG) and E. vermicularis (22.70 + 5.70 EPG). Approximately one third of the stray dog population (29.1%; n= 32) indicated ectoparasitic infestations, dominated by Rhipicephalus sanguineus (40.9%; n=45), Ctenocephalides canis (23.6%; n=26) and Ixodes scapularis (19.1%; n=21). The results of the Chi-square test of independence denoted that there was a significant difference on the prevalence of helminthic parasites, among male and female stray dog populations (χ2= 15.19, df = 7, P = 0.03). CONCLUSIONS: The present study revealed the potential risk on human health by intestinal helminthic and ectoparasites among stray dog populations. Hence, better understanding of such diseases and their control is essential.Item Prevalence of ectoparasitic infections and other dermatological infections and their associated factors among school children in Gampaha District, Sri Lanka(Hindawi Publishing Corporation, 2019) Gunathilaka, N.; Chandrasena, N.; Udayanga, L.Skin disorders are one of the commonest conditions among school children in developing countries. There are only a few published studies available from Sri Lanka on the prevalence of skin disorders. A community-based cross-sectional study was carried out among five government-run schools randomly selected from the district of Gampaha, Sri Lanka, during 2016-2017. A total of 41 students between 5 and 16 years of age were randomly selected from each school. Sociodemographic profile and hygienic behaviors of selected students were assessed using a pretested interviewer-administered questionnaire. Students were examined by a medical officer for the presence of different skin disorders. The chi-squared test of association and binary logistic regression were used for the identification of the significance of socioeconomic factors and hygienic practices among the study participants. A total of 205 school children participated in the study. The commonest skin disorder was pediculosis (42.0%; n=86), followed by dandruff (8.3%; n=17), fungal infections (6.8%; n=14), and scabies (1.5%; n=3). Almost one-fourth of the study participants (22.9%; n=30/131) had more than one disorder, majored by Pediculus captis infestation with dandruff. Over one-third (36.1%; n=74) were free of any skin disorders. The prevalence of skin disorders was significantly high among females (87.3%; n=110), compared to males (26.6%; n=21). Presence of long hair, higher family size, and limited number of rooms in the house were risk factors associated with the prevalence of skin disorders. The commonest skin disorder was pediculosis, while scabies and fungal infections were scarce among school children in the district of Gampaha, Sri Lanka. Implementation of health education and monitoring programs at the school level for maintaining the dermal health status of school children is recommended.
