ABSTRACT
Purpose
To evaluate the frequency of Human adenovirus (HAdV) and its serotypes in keratoconjunctivitis patients who attended the outpatient clinics of Mansoura Ophthalmic Center, Egypt.
Methods
Conjunctival secretions and corneal scrapings were collected from patients complaining of clinically diagnosed viral keratoconjunctivitis. The molecular method for HAdV detection was performed by polymerase chain reaction (PCR) followed by restriction enzymes (REA) determination of serotypes for hexone gene.
Results
HAdV infection was detected in 38% of samples. There were 4 serotypes of Human adenovirus species D (HAdV-D) isolated (4, 8, 37, 3), where HAdV-D8 was the most dominant. Contact with infected patient, follicular conjunctivitis and subepithelial corneal infiltrates are useful features for clinical diagnosis of adenoviral conjunctivitis.
Conclusion
HAdV was significant etiological factor of acute follicular conjunctivitis. Accurate diagnosis of adenoviral conjunctivitis is essential for appropriate management, reducing permanent visual impairment and to limit the transmission of the virus within the community.
