Molecular Study of Most Common Pathogenic Bacteria Isolated From Conjunctivitis Patients In Baghdad


The current study was conducted to investigate the causes of bacterial eye infections which included inflammation of conjunctivitis, and detection of molecular study of most common pathogenic bacteria at different age groups].The study was conducted in Educational laboratories of Microbiology-Baghdad medical city, involve taken sample from Ibn al-Haitham teaching hospital, Al-Kindi specialized hospital and Baghdad medical city / ghazi al– Hariri teaching hospital during the period from December / 2016 to Jun / 2017.Culture investigation showed 194 positive bacterial growth of 200,103 isolate represent Gram positive,91 isolate Gram negative, and 6 no growth. Most common bacteria were Staphylococcus aureus showed high percentage [41(20.5%)], While other bacteria less than Staphylococcus aureus.To the best of our knowledge this study was the first study in Iraq explained the molecular study of conjunctivitis patients. That concluded there 41cases infection with Staphylococcus aureus and showed all cases were methicillin resistance (MRSA), but not all carried gene mecA only [35(85.37%)], 13(31.71%) carried Panton-Valentine leukocidingene (PVL), and no one have VanA gene responsible of Vancomycin resistance.
