THE PREVALENCE OF SEN VIRUS GENOTYPES IN BAGHDAD CITY

SEN virus (SEN V) is one of worldwide incidence of blood borne pathogen. The most dominant genotypes among the nine genotypes of the SEN virus are SENV-D and H. The objective of this research was to determine the frequency of SENV genotypes particularly SENV- D and H genotypes in healthy Iraqi participant’s sera. Totally, 200 serum samples from healthy voluntaries were collected from both gender as well as subjected to nested PCR. SENV-D was detected in 30% healthy individuals and more frequent in tested male 51.25 than in female individuals 48.75%. The frequency of SENV-H was found in 5% of participants. SENV-D is the dominant strain in the Iraqi studied group followed by genotypes H. phylogenetic tree analysis of virus near-complete open-reading frame 1(ORF1), was performed, and the evolutionary relationship indicated that local isolates were very close to the group that included the Asian isolates.
