Isolation and characterization of bacteria from patients with conjunctivitis in hilla province

الملخص EN

This work therefore, aims to study the isolation and identification of common bacterial pathogens associated with conjunctivitis and examine some virulence factors such as (Capsule) Hemolysis, Siderophores, Extracellular Proteases and Adherence Factor and Show the effect of some antibiotics on bacterial isolates.

In our study, 120 conjunctiva swabs were subjected to isolate and identify the bacterial strains associated with conjunctivitis.

These swabs were obtained from patients suffering from conjunctiva inflammation of both sexes who were attended to the Hilla Teaching Hospital / Ophthalmic Unit in Hilla province. Bacterial infections were detected in 82 (68.3%) samples and no growth resulting in 38 (31.7%) samples.

It was indicated that Hemophilic influenzae was the first colonizer of the conjunctiva sac (49 isolates) among the children and adults, followed by Staphylococcus aurous (19 isolates), Streptococcus pneumonia (7 isolates) and a few number (4 isolates) of Neisseria gonorrhea on the first week of life were isolated, an act, which confirmed the predominance of Gram-negative bacteria early in life. Also (3 isolates) of Klebsiella pneumonia were isolated from children below one year old and from adults.

Some virulence factors of these bacterial isolates were investigated.

Also, investor effect of some antibiotics on these bacterial isolates was studied, and the results showed that Ciprofloxacin and Chloramphenicol were the most sensitive among the other drugs; hence they should be the first choice for the treatment of bacterial conjunctivitis.
