Abstract
The aerobic bacterial flora in normal and inflammed conjunctiva has been widely studied, although much less work has been done on anaerobic bacteria.
Results: This study highlights the aerobic bacterial flora in normal and inflamed human conjunctiva. This study comprised of hundred eyes with normal conjunctiva (control group) and an equal number of eyes with inflamed conjunctiva (study group). Staphylococcus albus was the predominant aerobic bacteria isolated from the normal conjunctiva. In the inflamed conjunctiva, 87% of the eyes were positive for bacterial culture and, no growth was seen in 13%. Aerobic bacteria were isolated in 83% (pure and mixed cultures). Staphylococcus aureus (31.69%) was the commonest aerobic bacteria recovered from cases of acute conjunctivitis in (2.81%). The difference between bacterial cultures isolated from normal and inflammed conjunctiva is statistically highly significant at p value of (0.01).
Conclusion: It is of utmost importance for the Ophthalmologist to consider the bacterial flora while treating patients with conjunctivitis and prophylaxis prior to surgery.
Keywords: Human conjunctiva, Aerobic Bacteria, Aerobic Culture.
