Two new genome types of adenovirus 7c.
Adenovirus type 7 is the type most frequently associated with serious disease. Eighteen different genome types of adenovirus type 7 had been reported up to October 1986. The genome type Ad7c, based on the restriction enzyme profiles of SmaI and BamHI, has been reported from Europe prior to 1969 and more recently from South Africa. Here, we report two new genome types of adenovirus 7 c that have not previously been identified and that have been isolated in South Africa between 1975 and 1986 from children with postmeasles pneumonia. The two new genome types differ from the prototype Ad7c virus in having two (Ad7c1) or one (Ad7c2) extra cleavage sites for the restriction endonuclease EcoRI. These sites have been located at 3.68kb and 5.32kb from the left terminus of the genome map published for the prototype Ad7c strain. A strain resembling the prototype Ad7c was also isolated in 1986 from a case of post measles pneumonia.
