Molecular prevalence of Enterocytozoon bieneusi in stray cats of İzmir, Türkiye

Comp Immunol Microbiol Infect Dis. 2023 Aug 4;100:102037. doi: 10.1016/j.cimid.2023.102037. Online ahead of print.ABSTRACTThe phylum Microsporidia contains obligate single celled parasites that can infect many vertebrate hosts including humans. Enterocytozoon bieneusi is considered as the most diagnosed species in humans. E. bieneusi has also been detected in many animals such as cats, dogs and cattle. Among these animals, cats are carriers of type D and IV which are the most common human pathogenic genotypes of E. bieneusi. In Türkiye, the prevalence of E. bieneusi in stray cats is not well known. Therefore, in this study, the molecular prevalence of E. bieneusi in stray cats (n = 339) was determined by Real-Time PCR targeting ribosomal DNA ITS (internal transcribed spacer) region of E. bieneusi. Initially, the analytical sensitivity of Real-Time PCR was determined by a plasmid control and then E. bieneusi DNA was investigated in fecal samples of stray cats. The results showed that the analytical sensitivity of Real-Time PCR targeting ITS region of E. bieneusi was ≤1 copy plasmid/reaction. Analysis of fecal samples revealed that the molecular prevalence of E. bieneusi was 50.15% (170/339). Overall, these results showed that the Real-Time PCR successfully detected E. bieneusi in cat's fecal samples and stray cats can be an important source for transmission of E. bieneusi to humans and other animals.PMID:37556942 | DOI:10.1016/j.cimid.2023.102037
