The transmission of hog cholera virus by Trichinella spiralis larvae.

Studies have been carried out to determine (a) the possible role of T. spiralis larvae in the transmission of hog cholera virus and (b) to determine the effect of elevated swine temperature on the viability of trichinae. Trichina larvae from hog cholera infected swine were freed from diaphragmatic tissue by artificial digestion. Washed and disinfected larvae transmitted hog cholera virus while the supernatant digestive fluid did not transmit the virus. Infectivity of the virus was lost when the larvae were transmitted through albino rats before administration to swine. Temperature elevation of the swine did not affect the viability of the trichinae.
