Molecular Characterization of Intestinal Microsporidia in Immunocompromised Patient in THI-QAR Province

Introduction: Immunocompromised host has one or more defects in the normal defense mechanisms that protect against infectious agents. Microsporidia are group of protozoa characterized via obligate intracellular and spore formation, detected many hosts. Up till now, 1300 microsporidia species more, related to 150 genera, were, microsporidiosis caused by microsporidia. Objectives: To conduct Molecular characterization intestinal immunocompromised patient Thi-Qar province cases. Patients Methods: Totally, two hundred stool samples were collected subdivided into 185 cancer patients 15 organ transplantation patients. Samples examined for light microscopy smears stained Chromotrope Kenyon stain PCR techniques. Results: using Polymerase chain reaction technique (PCR), eleven sample out 116 positive microscopic examination stain. Positive sent sequencing result showed current study similar three microsporidia, Enterocytozoon bieneusi, Encephalitozoon cuniculi intestinalis. Conclusion: The present confirmed presence infection is among Keyword: Molecular, ,
