Antibodies in urine of chimpanzees with chronic adenoviral viruria.
Many chimpanzees have naturally occurring chronic intermittent viruria with an adenovirus of a new type called Pan 11. Small amounts of neutralizing antibodies to Pan 11 adenovirus were found in the urine of chimpanzees. Urinary antibodies to adenovirus were mainly of the immunoglobulin G (IgG) class with some IgA antibodies also present. There was no neutralizing activity in urine against another adenovirus, Pan 9, which has been isolated from lymph nodes, but not from urine, of chimpanzees; however, sera of all chimpanzees had neutralizing antibodies to Pan 9 virus, some with titers similar to those of antibodies against Pan 11 virus. Antibodies reacting with simian cytomegalovirus by indirect immunofluorescence were found in sera of all chimpanzees tested and in two of six urines. There was no correlation between levels of antiviral IgG antibodies in serum and urine by immunofluorescence. These findings suggest that both IgG and IgA antibodies may be locally produced in response to viral infection of the urinary tract in primates.
