Trichinella Spiralis in the Diaphragms of Humans and Swine

The efficacy of flubendazole against Trichinella spiralis in swine.

A trial was undertaken to assess the efficacy of flubendazole against experimentally induced trichinellosis in pigs when given mixed with food at different dose rates. At the start of the experiment, 48 pigs were infected with approximately 35,000 larvae of Trichinella spiralis, afterwards the animals were distributed in six groups. The first three groups were used to test the activity of the d...

Comparison of IgM, IgG1 and IgG2 responses to Trichinella spiralis and Trichinella britovi in swine.

Pigs infected with T. spiralis and T. britovi were followed by double (IgG) and triple antibody ELISA (IgG1, IgG2 and IgM) during a 12-week-period. Specific IgG and IgG1 responses were similar and showed a significant relation with the infecting doses and intensity of infection. Response to T. britovi was slightly lower than in groups infected with the same dose of T. spiralis. IgG2 response wa...

Experimental Transmission of Trichinella spiralis to Swine by Infected Rats

The role of rats in the transmission of Trichinella spiralis to swine is controversial because some experimental investigations have failed to show that swine will eat rat carcasses. Confinement-reared, grain-fed hogs were offered fresh rat carcasses harboring varying densities of muscle larvae. In all trials, rat carcasses were readily eaten in part or in their entirety, usually within a few h...

Experimental and immunological comparison of Trichinella spiralis and Trichinella nativa

Distribution of Trichinella spiralis larvae in selected muscles and organs of experimentally infected swine.

Thirty-two Hampshire-Yorkshire pigs (6 to 8 wk old) were inoculated with the Beltsville strain of Trichinella spiralis at a level of about 880 larvae/kg of body weight (about 15 kg). At about 100 kg, the pigs were slaughtered and 10-g samples of muscle and other tissues were digested in pepsin-HC1 and examined microscopically for T. spiralis larvae. The mean number of larvae recovered/gram was:...
