Influence of intensity of infection on morphological characteristics of <i>Trichinella spiralis</i> larvae at experimental infection of white rats and their distribution in muscles
The purpose of the research is to study the morphological changes in the capsules of Trichinella spiralis larvae and their distribution in muscles.Materials and methods. In the experiment, 12 white rats were used, divided into 3 groups of 4 animals each. Rats of the first group were infected with T....

| description | The purpose of the research is to study the morphological changes in the capsules of Trichinella spiralis larvae and their distribution in muscles.Materials and methods. In the experiment, 12 white rats were used, divided into 3 groups of 4 animals each. Rats of the first group were infected with T. spiralis larvae at a dose of 5 larvae per 1 g of body weight, the second – at a dose of 40 larvae per 1 g, rats of the 3rd group served as control and were not infected. The selective dispersal of larvae was studied by determining the intensity of infection in post-mortem studies of the main muscle groups of the animal and measuring the capsules of larvae in different muscle groups.Results and discussion. In the entire muscle mass, 45±10 T. spiralis larvae/animal were found in the 1st group, in the 2nd group the number of larvae was 2250±180, in the control group no T. spiralis larvae were found. It has been established that the distribution of T. spiralis larvae in the muscles of infected animals depends on the dose of infection: at low doses, the largest number was found in the gastrocnemius muscles and diaphragm, at high doses, the number of larvae in the muscles of the head sharply increases. |
