Susceptibility of laboratory animals to Trichinella from synanthropic and natural foci of the northern Caucasus.

Laboratory animals were infected with larvae of four species of Trichinella. The tests have whown that T. pseudospiralis is highly infectious for golden hamsters and guinea pigs. Rats are relatively resistant to T. pseudospiralis but highly susceptible to T. spiralis. T. nelsoni turned out to be little infectious to rodents which were used in the experiment. T. nativa is little infectious for rats but more infectious for golden hamsters and guinea pigs as compared to T. nelsoni.
