During 1996-1998 epidemiological survey of domestic Trichinella spiralis infection and serological survey on human beings were carried out in Yanling, Xuchang counties and Luohe city. By the artificial digestion method, the positive rates of pork in market and mutton were 1.6% and 0.6% respectively. Meat samples of pigs from pig-farms, cats and dogs were all negative for Trichinella larvae. Tri...

Trichinella larvae collected from wildlife, domestic and synanthropic animals in Finland were identified to species by two molecular techniques: Random amplified polymorphic DNA (RAPD) polymerase chain reaction (PCR) and the recently described multiplex PCR. The RAPD-PCR was very sensitive to the sub-optimal preservation muscle larvae and resulting in weak and smeared bands on the gels for such...

—A common intertidal hoplonemertean species, Amphiporus nelsoni Sanchez, 1973, from Chile is re-described based on the investigation of material from the type locality and one other locality in Chile. The species is transferred to the genus Prosorhochmus Keferstein, 1862 (Prosorhochmidae) based on the presence of a dorsal epidermal fold, i.e., "prosorhochmid smile" on the bilobed head, truncate...

background: we have previously reported that a 31 kda protein was screened from the excretory-secretory (es) proteins of tichinella spiralis muscle larvae (ml) by immunoproteomics using early infection sera, and the gene encoding a 31 kda protein from t. spiralis was cloned and expressed in an e. coli expression system. in this study, the recombinant 31 kda antigens were used for detection of a...

Trichinellosis is a globally important food-borne parasitic disease of humans caused by roundworms of the Trichinella complex. Extensive biological diversity is reflected in substantial ecological and genetic variability within and among Trichinella taxa, and major controversy surrounds the systematics of this complex. Here we report the sequencing and assembly of 16 draft genomes representing ...

CRANDALL, RICHARD B., AND CRANDALL, CATHERIXE 4. 1972. Trichinella spiralis: Immunologic response to infection in mice. Experimen~tnl Purasitology 31, 378-398. Serum IgG1, IgG2. IgM, and IgA levels were measured by radial immunodiffusion in C57B1 mice after infection with 200 Trichinella larvae. IgG, concentrations increased 2to 5-fold during t,he second week of infection; IgA and IgGz levels s...

b ackground: the objective of this investigation was to detect the presence of trichinella in some carnivores of mashhad in northeast of iran and to identify trichinella species circulating in this area. methods: the present study was carried out using muscle tissue collected from 120 stray dogs, 26 wild boars, 25 rodents, two foxes and two hyenas captured in mashhad city, province of khorasan ...

In order to study the epidemiology of trichinellosis with special emphasis on swine a detailed study was performed. The goals of the study were to define the prevalence of trichinellosis in swine and rats and to determine the etiological agents of the disease with special emphasis on sylvatic species, Trichinella britovi. Considering the obtained data it can be concluded that the risk of Trichi...

Local environmental features can shape hybrid zone dynamics when hybrids are bounded by ecotones or when patchily distributed habitat types lead to a corresponding mosaic of genotypes. We investigated the role of marsh-level characteristics in shaping a hybrid zone between two recently diverged avian taxa - Saltmarsh (Ammodramus caudacutus) and Nelson's (A. nelsoni) sparrows. These species occu...
