Distribution of Trichinella spiralis, Trichinella britovi, and Trichinella pseudospiralis in the Diaphragms and T. spiralis and T. britovi in the Tongues of Experimentally Infected Pigs

Trichinella according to their geographical distribution and biological, morphological and biochemical characteristics: Trichinella spiralis; Trichinella nativa; Trichinella britovi; Trichinella pseudospiralis; Trichinella murrelli; Trichinella nelsoni; Trichinella papuae;

The first outbreak of human trichinellosis in China,according to official national publication,was registered in Tibet in 1964. Since then,more than 500 outbreaks, numbering 25 161 cases with 240 deaths, have been recorded.However, this reported quantity is probably highly underestimated because adequate diagnostic techniques might not have been available in the whole area.Moreover, infection i...

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...

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...

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

We developed a detection system for myogenic regulatory factors such as MyoD and myogenin. Adapting the method we performed a longitudinal analysis of such regulatory factors after infection with T. spiralis and T. pseudospiralis. MyoD and myogenin were expressed from the early phase of cystogenesis in T. spiralis infection. The expression returned to the normal level after 18 days from the inf...
