 This study has shown that Entomeba-Moscowski is a significant cause of amoebiasis in eastern India and is likely to be an emerging enteric pathogen in the region. The results suggest that the species may have undergone a population expansion following a bottleneck event or selective sweep, which could explain its high prevalence in the region. Furthermore, the study also provides evidence of genetic diversity between different subgroups of the species, suggesting that there may be differences in virulence between these subgroups. This information can be used to develop more effective control measures against the species. This article was authored by Sanjib K. Sardar, Ajanta Goshaal, Tapas Holdar, and others.
