Many bunyaviruses of the Bunyamwera and California serogroups are medically
important human pathogens. The development of an effective technique to
detect the viruses by using molecular biologic tools, such as PCR, improves
not only clinical diagnosis but also virologic surveillance of mosquito
vectors in the field. In this study, we evaluated eight pairs of primers
for reactivity with 44 viruses of the genus Bunyavirus, using a reverse
transcriptase PCR technique. With a pair of serogroup-specific primers we
designed, all viruses of the serogroups tested could be detected. Further,
virus-specific primer pairs were identified for California encephalitis
virus, Jamestown Canyon virus, La Crosse virus, and snowshoe hare virus for
use in North America. Using this technique, we could detect one La Crosse
virus- infected mosquito in a pool of 100 mosquitoes with undetectable
plaque titers.
