Rare Case of Human Ancylostoma ceylanicum Infection in Bangladesh

The zoonotic hookworm species Ancylostoma ceylanicum has drawn more attention recently because of its potential impact on public health. Although A. duodenale and Necator americanus are more common, A. ceylanicum is still known to play a major role in human infections, particularly in regions where close human-animal interactions are prevalent. Although there has been a notable increase in documenting the presence of A. ceylanicum in the Asia-Pacific area, bottleness remains in understanding its epidemiology in Bangladesh. This report highlights the first documented case of Ancylostoma ceylanicum infection isolated and identified in a 15-year-old girl experiencing frequent diarrhea and weakness, residing in an urban tea garden area in Sylhet, Bangladesh. Microscopic examination of stool samples revealed the presence of hookworm eggs and subsequent culture led to the observation of larvae. Molecular investigation by amplifying ITS1+ regions confirmed the infection as A. ceylanicum. The identification of Ancylostoma ceylanicum in a human host in Bangladesh carries significant implications for global health. The careful measurement of eggs and larvae, coupled with molecular analysis, serves as an appropriate diagnostic strategy for confirming the infections. This finding emphasizes the emergence of A. ceylanicum as a zoonotic infection in endemic regions and calls for increased awareness among healthcare professionals and the general public.
