TAENIASIS IN BANGLADESH: SITUATION AND FUTURE PERSPECTIVES (ID 2092)
DYNAMICS OF HELMINTH INFECTIONS IN EPIDEMIC AND EPIZOOTIC SYSTEMS OF BANGLADESH (ID 52)
Abstract
Introduction
In view of a growing international commitment to control human helminths infection, there is an urgent need to intensify the detection of the cases from reservoir hosts. This study was performed to reveal the dynamics of helminthic infections in the epidemic and epizootic systems of Bangladesh with the concept of One Health.
Methods
We employed a combination of qualitative and quantitative methods including cryomicroscopy, scanning electron microscopy, sedation, culture, molecular approaches, and interviews. Specimens (human stools, animal feces, and soils) were collected from the three ecological areas in Bangladesh.
Results
The ecological zone shared by host communities is rich in diversity of helminths, of which some are extensively shared across the host species. Humans, animals, and soils showed an overall prevalence of 31.7%, 59.3%, and 52.5% respectively. Diverse species of helminths include Ascaris, Trichuris, Capillaria, hookworms, Hymenolepis, Enterobius, Rhabditis. Toxocara, Spirometra, opisthorchiid, Fasciola, Paramphistomum, roundworms, taeniid were detected. For the first time in Bangladesh, nematodes, i.e., Rhabditis sp. from human, Agriostomum sp. from goat, Ancylostoma caninum from soil, and cestode Spirometra decipiens was reported from lion. This study also developed a context-based method for geohelminths recovery and the method proved feasible in terms of field applicability and egg recovery rate.
Conclusions
This study provides the overall infection status of helminths in humans, animals, and soils from similar ecological settings. This pattern would be helpful for understanding helminth propagation, environmental persistence, and transmission.
