Amelioration of Myogenin, Bcl-2 expression and DNA damages in myocytes of Trichinella spiralis-infected mice after immunization with gamma radiation-attenuated larvae
Background: In trichinosis, the presence of muscle larvae inside skeletal striated muscle causes loss of identity and function of myotube through the releasing of myogenin and myosin. Considering the dominant role of vaccination, research on gamma radiation-attenuated vaccine has very promising value. The goal of this study was to determine the efficacy of vaccination with radiation-attenuated ...
متن کاملImmune responses in mice vaccinated with a DNA vaccine expressing serine protease-like protein from the new-born larval stage of Trichinella spiralis
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...
متن کاملTaxonomy of Trichinella and the epidemiology of infection in the Southeast Asia and Australian regions.
Seven species belonging to the Trichinella genus (five with encapsulated larvae and two with non-encapsulated larvae in host muscles) and three additional genotypes have been described to date: T. spiralis (genotype T1), a cosmopolitan species with a high infectivity to swine and rats; T. nativa (T2), etiological agent of sylvatic trichinellosis in arctic and subarctic areas of the Holarctic re...
متن کاملSurvival of North American genotypes of Trichinella in frozen pork.
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...
متن کاملReduction of muscle larvae burden in rats experimentally infected with Trichinella spiralis.
In Wistar rats infected with 500 to 2,500 Trichinella spiralis larvae the muscle larvae intensity (larvae per gram-l.p.g.) was measured from 20 to 180 day post infection (d.p.i). The l.p.g. increased to day 40-50 p.i. and decreased thereafter. The highest reduction took place between 60 and 120 d.p.i. with intermediate inoculum of T. spiralis larvae. The mechanism of the reduction of T. spirali...
