Аннотация
A study of conjunctivitis cases with a possible viral cause was carried out in Havana City during June and August, 1993. Thirty seven cases from "Ramón Pando Ferrer" Ophthalmological Hospital were studied, of whom 13 isolations (35.1%) in cell culture of Hela cells were obtained. Isolations showed a cytopathic effect characteristic of Adenovirus. A direct immunofluorescence with conjugated serum of rabbit specific to Adenovirus was performed and results were positive in 100% of cases. A DNA restriction analysis of each isolated was performed for their classification. Restriction endonucleases SmaI and Hind III were used and 2 isolates were classified as Adenovirus type 3, and 6 as Adenovirus type 7b, 4 out of 13 isolates were not classified because of the degradation of the genetic material.
