Clinical Information:
Eye infections are usually caused by bacteria, fungi and viruses. Bacterial conjunctivitis is more common in children. The most common bacteria are Haemophilus influenza, Streptococcus pneumoniae and Staphylococcus aureus.
 
Reference Value:
No growth or usual flora
 
Interpretation:
Any microorganism found where no resident flora is present is considered significant and is reported. For specimens contaminated with the usual bacterial flora, bacteria that are potentially pathogenic are identified.
