Expression of MyoD and myogenin in muscles of mice experimentally infected with Trichinella spiralis or Trichinella pseudospiralis.

Amelioration of Myogenin, Bcl-2 expression and DNA damages in myocytes of Trichinella spiralis-infected mice after immunization with gamma radiation-attenuated larvae

Background: In trichinosis, the presence of muscle larvae inside skeletal striated muscle causes loss of identity and function of myotube through the releasing of myogenin and myosin. Considering the dominant role of vaccination, research on gamma radiation-attenuated vaccine has very promising value. The goal of this study was to determine the efficacy of vaccination with radiation-attenuated ...

Infectivity, reproductive capacity and distribution of Trichinella spiralis and T. pseudospiralis larvae in experimentally infected sheep.

Twelve Merino sheep were experimentally shown to be susceptible to infection with Trichinella spiralis or T. pseudospiralis by feeding on infected carcasses of mice or by oral intubation with recovered muscle larvae. The larvae recovered from the sheep showed variable tissue distribution. The diaphragm and tongue were most affected. The viability of the recovered larvae was confirmed by success...

Cross resistance against challenge infection in mice infected with Trichinella spiralis or T. pseudospiralis.

Susceptibility of Laboratory Rodents to Trichinella papuae

Members of the genus Trichinella are small nematodes that can infect a wide range of animal hosts. However, their infectivity varies depending on the parasite and host species combination. In this study, we examined the susceptibility of 4 species of laboratory rodents, i.e., mice, rats, hamsters, and gerbils to Trichinella papuae, an emerging non-encapsulated Trichinella species. Trichinella s...

Survival of North American genotypes of Trichinella in frozen pork.

North American genotypes of Trichinella spiralis (T-1), Trichinella nativa (T-2), Trichinella pseudospiralis (T-4), Trichinella murrelli (T-5), and Trichinella T-6 were examined for susceptibility to freezing in pork using time-temperature combinations that have been proven to inactivate T. spiralis. Infections were established in 3-month-old pigs of mixed sex and breed by oral inoculation of 1...
