Retrospective Evaluation of Intestinal Protozoa Parasites in Patients Presenting to Kafkas University Health Research and Application Hospital Between 2019-2022.

OBJECTIVE

This study aimed to retrospectively evaluate the prevalence of protozoan parasites in stool samples collected from patients presenting with various gastrointestinal complaints to the Medical Parasitology Laboratory of Kafkas University Research and Application Hospital between 2019 and 2022.

METHODS

Stool samples were initially examined using the native-Lugol method for the detection of protozoan parasites, followed by the formol-ethyl acetate sedimentation method, Giemsa, and carbol fuchsin staining methods. Specific immunochromatographic card tests were used for the diagnosis of Entamoeba histolytica, Cryptosporidium spp., and Giardia intestinalis.

RESULTS

Of the 2.267 stool samples examined over the four-year period from January 2019 to December 2022, 7.63% were found to contain one or more protozoan parasites. Among these parasites, Entamoeba histolytica was detected at the highest rate of 4.06%. The other parasite species were identified as follows: Blastocystis spp. 1.15%, Entamoeba spp. and Entamoeba coli each 0.52%, Giardia intestinalis 0.48%, Endolimax nana 0.17%, and Entamoeba histolytica/dispar 0.08%.

CONCLUSION

This study indicates that despite a decrease in the prevalence of intestinal protozoan infections in the Kars region, these infections remain a significant public health issue. Therefore, improvements in hygiene and sanitation conditions, increased public health education, and the widespread implementation of early diagnosis and treatment methods are necessary. Special measures should be taken to protect vulnerable groups, particularly children and the elderly.
