Background:
Microsporidia have been reported as the cause of opportunistic infections in immunocompromised patients in Iran and other countries. There is no data on prevalence of intestinal microsporidia in healthy population of Iran. This study aimed to provide preliminary data on the present status of microsporidia infection in the local healthy population in Jiroft, Kerman Province from southeastern Iran in 2013-2014.
Methods:
Fresh stool samples were randomly collected from 418 residents in rural 209 (50%) and urban 209 (50%) areas of Jiroft. All of the collected samples were concentrated with conventional formalin-ether, stained with Ryan blue. Microscopic examination was performed with high magnification on each sample separately for the demonstration of microsporidia spores.
Results:
Microsporidial spores were identified in 41 out of 418 (9.8%) samples including 16.41(39%) from rural areas and 25.41(61%) from urban areas. In general, there was no significant difference between sex, age, job, education, and contact with soil and livestock, water supply, gastrointestinal disorders and microsporidia infection among general population in Jiroft.
Conclusion:
Intestinal microsporidia infection without clinical manifestations is prevalent in general population resident in southeastern Iran. Appropriate molecular methods are needed for microsporidia species identification.
Insights
Intestinal microsporidia infection is prevalent in Iran
Area of Science:
- Parasitology
- Infectious Diseases
- Public Health
Background:
- Microsporidia cause opportunistic infections in immunocompromised individuals.
- Data on intestinal microsporidia prevalence in Iran's healthy population is lacking.
- This study investigated microsporidiosis in a healthy Iranian population.
Purpose of the Study:
- To determine the prevalence of intestinal microsporidia in the healthy population of Jiroft, southeastern Iran.
- To provide preliminary data on the status of microsporidiosis in this region.
Main Methods:
- Stool samples were collected from 418 healthy residents in rural and urban areas of Jiroft.
- Samples underwent formalin-ether concentration and Ryan blue staining.
- Microscopic examination was used to detect microsporidia spores.
Main Results:
- Microsporidial spores were detected in 9.8% of samples (41/418).
- Prevalence was higher in urban (61%) compared to rural (39%) areas.
- No significant differences in infection rates were observed based on sex, age, job, education, or environmental factors.
Conclusions:
- Asymptomatic intestinal microsporidia infection is common in the general population of southeastern Iran.
- Further molecular studies are required for accurate species identification.
