Prevalence of cryptosporidiosis in domestic and stray cats in Mymensingh, Bangladesh

Abstract

Background: Cryptosporidium sp. infection is a significant zoonotic disease affecting both humans and animals, including cats. The primary objectives of this research were to determine the prevalence of Cryptosporidium sp. infection and to identify the pathological lesions caused by the infection in domestic and stray cats in the Mymensingh district, Bangladesh.

Methods: In this study, fecal samples from 36 cats were collected and analyzed using both direct smear and safranin staining methods to detect Cryptosporidium oocysts. Additionally, the intestines of euthanized cats were examined for gross and microscopic lesions. The study was performed at the Department of Parasitology and the Department of Pathology, Bangladesh Agricultural University, Mymensingh, Bangladesh.

Results: A total of 36 adult cats (16 males and 20 females) were examined. Among them, three cats (8.3%; 95% Confidence Interval: 2.2–23.6) tested positive for Cryptosporidium sp. infection. The prevalence was higher in young cats under 1 year of age (16.6%) compared to adult cats over 1 year (4.1%). Females showed a higher prevalence (10%) compared to males (6.2%). The infection was detected throughout the year except during the winter season. Prevalence was higher during the summer season (15.4%) compared to the rainy season (8.3%). However, none of the observed differences in prevalence by age, sex, or season were statistically significant.

Conclusion: The study highlights that Cryptosporidium sp. infection is a health concern for both domestic and stray cats, regardless of their age, sex, or season. Regular screening and treatment of domestic cats are recommended to reduce the risk of zoonotic transmission to humans.
