Since 1995, Trichinella larvae have been detected in 39.5% of farmed crocodiles (Crocodylus niloticus) in Zimbabwe. Morphological, biological, biochemical and molecular studies carried out on one isolate from a farmed crocodile in 2001 support the conclusion that this parasite belongs to a new species, which has been named Trichinella zimbabwensis n.sp. This species, whose larvae are non-encaps...

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...

The European Union (EU) countries are searching for new ways to certify meat free of Trichinella; however, with the expansion of the EU, the acceptance of a unilateral method is complicated by the variability of pig and human trichinellosis among EU countries, where significantly higher prevalence rates have been observed in the newly added eastern countries. Several attempts have been made to ...

Introduction Roundworms of the genus Trichinella are spread worldwide and are responsible for one of the most serious helminthic zoonoses. It is recognized that in many parts of the world none of the existing methods of control for Trichinella infection are applied because of the economic problems, erosions of veterinary infrastructures, failure of educational systems, ineffective abattoir cont...

Parasitic nematodes of the genus Trichinella cause significant food-borne illness and occupy a unique evolutionary position at the base of the phylum Nematoda, unlike the free-living nematode Caenorhabditis elegans. Although the forthcoming genome sequence of Trichinella spiralis can provide invaluable comparative information about nematode biology, a basic framework for understanding the histo...

Hunting in Poland has a long tradition and became more popular after 1990. Each year over 60,000 wild boar are hunted. Some of them may act as Trichinella carriers thus all carcasses of wild boar are systematically sampled in game-handling establishments as part of the post-mortem examination. The aim of the study was to determine the species of Trichinella and to evaluate the year to year diff...

The genus Trichinella is currently divided into seven species and at least three additional, unclassified genotypes, Trichinella T6, T8 and T9, where both T8 and T9 have been deemed very similar to T. britovi. Other than for the non-encapsulated species, the absence of distinguishing morphological characters and the overlapping nature of the biological characters within this genus make these tr...

Several outbreaks of trichinellosis associated with the consumption of raw pork have occurred in Laos since 2004. This cross-sectional study was conducted in four provinces of northern Laos to investigate the seroepidemiology of trichinellosis in the human population and determine the prevalence and species of Trichinella infection in the domestic pig population. Serum samples and questionnaire...

Six species of rodents from Kern County, California, were inoculated subcutaneously with western equine encephalomyelitis (WEE) virus to determine their susceptibility to infection and their potential as natural hosts. Ammospermophilus nelsoni, Citellus beecheyi, Dipodomys heermanni, Dipodomys nitratoides, Peromyscus maniculatus, and Sciurus griseus were readily infected. Infection was usually ...
