The Swine Lungworm as a Reservoir and Intermediate Host for Hog Cholera Virus
Evidence that the swine lungworm can serve as reservoir and intermediate host for the hog cholera virus has been presented. The virus, however, is ordinarily carried in a masked form and must be provoked to pathogenicity by some stress before it can cause apparent disease. In the present experiments, ascaris larvae supplied the provocation needed to induce hog cholera in swine carrying lungworm...
متن کاملThe Swine Lungworm as a Reservoir and Intermediate Host for Swine Influenza Virus
1. The presence of masked swine influenza virus has been demonstrated in lungworm larvae from earthworms dug on Midwestern farms. 2. Swine influenza virus infections were provoked in 2 of 3 swine obtained from an Iowa farm during an interepizootic period. 3. The evidence presented has been interpreted as indicating that the swine lungworm is the reservoir and intermediate host for swine influen...
متن کاملAn Intestinal Threadworm as a Reservoir and Intermediate Host for Swine Influenza Virus
A laboratory model exemplifying Shope's concept of virus carriage by helminths was developed using Strongyloides ratti (Sandground, 1925), swine influenza virus, and caesarean-originated, barrier-sustained (COBS) mice and rats. It was shown that S. ratti can act as a carrier of swine influenza virus and infect mice, despite the fact that the nematode has undergone a complete life cycle after ex...
متن کاملHOST FOR SWINE INFLUENZA VIRUS II. THE TP.ANSmSSlON OF SWINE IN:FLUENZA VIRUS BY THE SWINE LUNGWOI~
In the preceding paper (1) experiments have been described in which swine influenza virus infections were elicited in apparently normal swine by multiple intramuscular injections of suspensions of either living or heat-killed Hemophilus influemae suis. The findings suggested that the virus of swine influenza had been present somewhere in the pigs at the time of injection. In the present paper i...
متن کاملThe structural components of hog cholera virus.
Hog cholera virus grown in PK-15 cells and SK-cells was labeled with [35S]methionine and [3H]uridine. At least 3 polypeptides were resolved by polyacrylamide gel electrophoresis after disruption of the virus with sodium dodecyl-sulfate. The molecular weights of the structural proteins were determined to be 55000 (p55), 46000 (gp46), and 36000 (p36). The molecular weight of the viral RNA was det...
