Thus, this study is aimed at assessing the prevalence and associated factors of intestinal parasitic infections among inmates of Hosanna town prison. <b>Materials and Methods:</b> An institution-based cross-sectional study was conducted in Hosanna Town's prisoners from June 1 to July 30, 2022, on a total of 420 inmates. The study participants were chosen using a simple random sampling technique. Sociodemographic, sanitation, hygienic, and related information were collected by using pretested questionnaires. In addition, about 5 g of stool sample was collected using a leak-proof plastic stool cup and examined microscopically by using direct wet mount preparation and formalin-ether concentration techniques, and data were analyzed by using SPSS Version 25. <b>Results:</b> This study indicated an overall 39.2% (95% CI: 34.6-44.1) prevalence of intestinal parasites (165/420). <i>Entamoeba histolytica/dispar</i> was the most prevalent intestinal parasite found, followed by <i>Giardia lamblia, Ascaris lumbricoides, Hookworms, Taenia</i> species, and <i>Schistosoma mansoni</i>. About 3.1% of participants had dual parasitic infections. In addition, there is a significant association in multivariable logistic regression analysis between intestinal parasitic infection and various hygiene practices such as not using soap when washing hands after using the toilet ((aOR 1.62 (95% CI: 1.06-2.48)), <i>p</i> ≤ 0.027), not regularly washing hands before meals ((aOR 2.83 (95% CI: 1.79-4.46)), <i>p</i> ≤ 0.001), poor hand hygiene overall ((aOR 3.18 (95% CI: 2.00-4.99)), <i>p</i> ≤ 0.001), not trimming fingernails ((aOR 2.09 (95% CI: 1.29-3.37)), <i>p</i> ≤ 0.003), and length of time in prison (aOR: 4.27, 95% CI: 22.62-6.96, <i>p</i> = 0.001). <b>Conclusions:</b> The findings of the study indicated that the overall prevalence of intestinal parasitic infections was 39.2%, with 38.8% of the infected individuals falling within the 25-34 age range. Additionally, 67.3% of those infected had been imprisoned for over a year. Furthermore, the personal hygiene status of prisoners was found to be substantially correlated with the presence of parasites.

The exchange of parasites between different host species is common in nature and often involves intermediate hosts or sharing space such as pastures or watering holes.

One such effect is an increased risk of parasitic infections, particularly in social animals. We quantified the prevalence of selected helminths typically found in cervids, in samples of the European bison faeces, using molecular methods, and compared endoparasite species richness between supplementarily fed and nonfed European bison herds in the Białowieża Primeval Forest, NE Poland. <b>Methods:</b> Using the diagnostic PCR method, we analysed the faecal samples for molecular markers of nine parasite species which are typically found in cervids: moose, red deer, and roe deer. <b>Results:</b> All analysed samples tested positive for at least one parasite species, and the average number of parasite species per sample was 3.2.
