Genotypic characterization on antibiotic resistant genes of Staphylococcus aureus isolated from conjunctivitis patients

Abstract

Bacterial conjunctivitis has a worldwide distribution, affecting persons of all ages and both genders.The study aimed to genotyping determination of antibiotic resistance genes in S.aureus . Thus,40 conjunctival swabs were collected from patients suffering from conjunctivitis were attended to Hospital in Al-Najaf province.The PCR amplification results for the predominance of S. aureus antibiotic resistance genes show that :10 (24.39 % ) of isolates have Neomycin resistances genes ( neo ) , While 5 ( 62.5% ) and 3 ( 75 % ) of isolates showed Gentamycin resistance gene (Tn1696 aacC1) and Chloramphenicol resistance genes (Tn9 cat ) respectively. Staphylococcus aureus is the common Bacterial predominance in conjunctivitis and appear a variable susceptibility for common antibiotics used in the treatment of conjunctivitis .
