A serological survey of simian virus 40 in monkeys.
A serological survey of simian virus 40 (SV 40) was conducted by an immune adherence hemagglutination (IAHA) test in breeding monkeys. Of a total of 356 monkeys tested, 168 (47.2%) were seropositive. All 168 seropositive monkeys were detected from 224 monkeys which were bred or kept in Japan for a long time. In contrast, none of the 132 monkeys which were newly imported from Southeast Asia was seropositive. If a comparison was made in the same breeding place, the positive rate of 80.4% (111/138) of Japanese monkeys was significantly (P less than 0.01) higher than the 59.5% (25/42) among rhesus monkeys. The positive rate and the IAHA titers were higher in older age group (greater than 5 years) but similar in male and female. These results indicated that SV 40 was highly prevalent among breeding monkeys in Japan.
