Abstract
Objective: This study aimed to determine the adenovirus genotypes and their epidemiological features between January 2018 and
 November 2019, in Istanbul, Turkey.
 Material and Methods: Conjunctival swab samples were obtained from patients who were clinically diagnosed with keratoconjunctivitis.
 Samples were screened with an Adeno Detector kit (Rapid Pathogen Screening, RPS Inc., South Williamsport, PA). Nucleic acid
 extraction and amplification were performed with the ADENOVIRUS ELITe MGB® kit in the ELITe In Genius instrument (Elitech
 Group, Torino, Italy). For subtyping of the strains, sequencing primers targeted the ‘Hypervariable Region 7’ (HVR-7) of the hexon
 gene were used. DNA sequence analysis (n:72) was performed with ABI PRISM® 3100 Genetic Analyzer (Applied Biosystems, USA),
 and subtyping was done by BLAST analysis.
 Results: The median viral load in the samples (n: 77) was 7 log10 copies/mL (IQR: 4.5-7.4 log10 copies/mL). The clinical finding score
 was found to be significantly higher in the high viral load group (Adenovirus DNA≥6 Log 10 copies/mL) than in the low viral load
 group (Adenovirus DNA
