[Experimental infection of green monkeys with adenoassociated virus]

Primary infection and reinfection with adeno-associated virus type 4 (AAV-4) was reproduced in green monkeys experimentally infected with AAV-4 in mixture with adenovirus. Wide dissemination of the satellite virus in animals was observed. AAV-4 and its antigen were detectable 5 to 23 days after inoculation. In monkeys infected with a mixture of AAV-4 and adenovirus or with one of them the infection was accompanied by a marked fever persisting from the 5th to the 20th day after inoculation. The infected monkeys showed an intensive rise of homologous antibody titer most marked on the 10th-15th day after inoculation with AAV-4. AAV-4 and its antigen were detected in smears from conjunctival and tonsillar mucosa, rectal specimens in the time course of the infectious process, as well as from the trachea, lungs, liver, spleen, intestines and kidneys of the sacrificed monkeys. Besides, AAV-4 antigen was found in cells of the tonsils and blood leukocytes of the sacrificed monkeys. No virus or its antigen were found in the brain and heart tissues. Virions of adeno-associated virus were found by electron microscopic examinations of kidney cells of one of 3 monkeys infected with AAV-4.
