Mice challenged intravenously with Listeria monocytogenes at 7 or 21 days after Trichinella spiralis infection demonstrated a higher mean lethal dose and longer survival time than normal mice. This effect of helminthic infection was abrogated after 49 days.

Previously described methods for the recovery of intestinal Trichinella worms from rodents are not feasible when applied in larger experimental animals such as foxes. In this study,worm recovery by standard technique of simple incubation of the intestine in saline was compared to embedment of the intestine in an agar gel. The small intestines of Trichinella spiralis infected foxes (4-5 days pos...

background: the intraperitoneal injection is a common method for establishing the experimental animal model infected with parasites. the aim of this study was to investigate if the intraperitoneal injection was another route of trichinella spiralis infection. methods:  from june to july 2015, twenty balb/c mice were intraperitoneally injected with 300 t. spiralis muscle larvae in department of ...

Six diethylaminoethyl-cellulose fractions of a larval Trichinella spiralis extract, an Ascaris suum extract, and a nonrelated protein were used for cutaneous tests in guinea pigs with 8-, 14-, and 73-day-old T. spiralis infections, in guinea pigs with 13-day-old A. suum infections, and in normal guinea pigs. A selected T. spiralis fraction was used in hemagglutination (HA) tests with sera of 8 ...

Trichinella spiralis is a parasitic helminth that can infect almost all mammals, including humans. Trichinella spiralis infection elicits a typical type 2 immune responses, while suppresses type 1 immune responses, which is in favour of their parasitism. DNA vaccines have been shown to be capable of eliciting balanced CD4+ and CD8+ T cell responses as well as humoral immune responses in small-a...

The horse is considered an aberrant host for the nematode parasite Trichinella spiralis, and many aspects of the biology and epidemiology of Trichinella infection in the horse are poorly understood. It has been reported that experimentally-infected horses produce a transient serological response to infection and that muscle larvae are cleared more rapidly than in parasite-adapted hosts such as ...

Intensive epidemiological and seroepidemiological studies of Trichinella spiralis infection in swine have been carried out in the borough of Kladovo, one of the four regions in Yugoslavia where trichinellosis is endemic. A high prevalence (4.7%) of trichinellosis was discovered in three neighboring parishes adjoining the bank of the river Danube. Both geographically and epidemiologically these ...

Background. Trichinellosis is a parasitic zoonosis transmitted to humans by consumption of raw or undercooked meat from animals infected by worms of the Trichinella genus. Every year seropositive cases are found among the human population and thus trichinellosis still remains an epidemiologically important disease in Poland. The usefulness of ELISA for anti−T. spiralis IgG detection in pigs is ...

Time of survival and infectivity of Trichinella spiralis larvae in pig muscle tissue, buried at various depths in the ground were assessed. In the pork pieces the number of infective larvae was 250 ML/g. Meat originated from pig halves was divided in 39 equal pieces, 0.7 kg each, disposed in three groups of 1 3, and buried in depths of 30, 50, and 100 centimeters respectively. The pork was dug ...
