- Abstract
The studies have shown that the distribution of this parasite is globally vast, and it is present in both temperate, tropical and arctic areas. The research aimed at isolating and examining the Trichinella spp. larvae from samples of muscle tissue collected from wild animals from the forest enviroment in the Dolj County (Radovan forest): fox Vulpes vulpes (Linnaeus, 1758), (2 samples), wild boar Sus scrofa (Linnaeus, 1758), and common rat Rattus norvegicus (Berkenhout, 1769) (a sample), mentioning that the disease was reported in 1999 in other species of wild animals raised in captivity (Panthera leo - lion) (Linnaeus, 1758) - The Zoo from the "Nicolae Romanescu" Park in Craiova, and the causes that led to the death of the animal being frequent feeding with infested horse meat. The experiments were performed using the equipments and devices of the parasitology laboratory within the L.S.V.S.A - Dolj, by two methods: the artificial digestion method and the Trichinella spp. parasite detection method by trichinelloscopic examination. Trichinelloscopic examination allows the differentiation of Trichinella and Sarcocystis cysts, the latter being arranged among the muscle fibers not being delimited by fibrillar layers that form a secondary cystic wall. Trichinella spiralis is the Trichinella species with the highest infectivity of domestic pigs Sus scrofa (Linnaeus, 1758), Rattus norvegicus rats (Berkenhout, 1769) and Mus musculus mice (Berkenhout, 1769). It can be said that that the wild environment can still be considered a reservoir of Trichinella spp. for domestic animal species. The results of the performed investigations may provide information for taking action regarding the diffusibility of trichinellosis in the forest environment such as the proper lifting and disposal of the wild animal carcasses from forests, rodent control around farms or households.
