Abstract


Background: Amoebiasis is still a leading cause of intestinal parasitic infections in the world. It can be asymptomatic or manifest a wide variety of presentation and hence its diagnosis of the pathogenic from the non-pathogenic is quite challenging. Methodology: However, a changing pattern has been observed over the years with this pathogen. This study tried to explore the changing trends in patients infected with this pathogen over a period of 3 years. Results:E. histolytica microscopy was positive in 55 cases with no gender predisposition. Most of the patients presented with mild abdominal pain associated with diarrhea. In this study we found that there is a decrease in prevalence of infection caused by vari-ous Entamoeba species. The overall positivity of infection was 3% during the study period, which could most probably be due to improper sanitation favouring the transmission of the disease. Conclusion: There has been increasing trend towards the non-pathogenic ones being recovered from the patients. This observation is especially applicable in light of the fact that expanding significance has been given to generally nonpathogenic species such as E. dispar and E. moshkovskii, since invasive amoebiasis has been exhibited to be related with these species. All things considered, the determinants of invasive amoebiasis are complicated and furthermore include different host factors
