Summary

Blastocystis is an anaerobic unicellular protozoal parasite infecting the gastrointestinal tract of humans and a wide range of animals. It is one of the most common enteric microorganisms with higher prevalence rates in developing than in developed countries. Feco-oral is the main route of transmission where low socioeconomic conditions, poor hygienic practices, close contact with animals, and drinking contaminated water act as major risk factors. Infection with Blastocystis was demonstrated in both symptomatic and asymptomatic people. For a long period, Blastocystis was considered a commensal organism with no pathogenic role, but recently, many studies linked it to different gastrointestinal symptoms such as nausea, diarrhea, and abdominal pain. Association with irritable bowel syndrome and colorectal cancer was also reported.

This study aims to:

\- Identify subtypes of human Blastocystis isolates in Sohag by using RFLP-PCR and provide additional information on the molecular epidemiology of this parasite in our locality.

Conditions

  • Blastocystis Infections

Interventions

DIAGNOSTIC_TEST

RFLP analysis of SSU rRNA

1. Genomic DNA will be extracted from Blastocystis-positive fecal samples using a specific DNA Stool Mini Kit according to the manufacturer's instructions and will be stored at -20°C until use. 2. PCR will be used to amplify a region of Blastocystis small subunit ribosomal RNA (SSU rRNA) gene. 3. The amplified products for the SSU rRNA gene will be digested to determine the strain subtype of Blastocystis spp. using specific restriction enzymes.
