OBJECTIVE
To assess performance of a synthetic carbohydrate antigen for use in an enzyme immunoassay for diagnosis of trichinellosis in swine. ANIMALS AND SAMPLE POPULATION: 47 York X Duroc pigs and field sera from 265 farm pigs raised under various management systems.
METHODS
Each of 47 pigs was
An important approach to the study of trichinellosis is the development of sensitive diagnostic methods that allow the detection of Trichinella spiralis. Recently, ELISA assays that use surface/stichosome and/or secretion/excretion antigens from muscle larvae have been proved to be highly sensitive
The most commonly used serodiagnostic antigens for trichinellosis are the excretory-secretory (ES) antigens from T. spiralis muscle larvae (ML), but the specific antibodies against the ML ES antigens are usually negative during early stage of Trichinella infection. The recent studies demonstrated
Trichinella spiralis, an intracellular parasitic nematode, can cause severe foodborne zoonosis, trichinellosis. The life cycle of T. spiralis consists of adult (Ad), muscle larvae (ML) and newborn larvae (NBL). The protein profiles in different developmental stages of the parasite remain unknown. In
Primary exposure to Trichinella spiralis in the rat, while immunizing against reinfection, induces changes in the carbohydrate structure of intestinal brush border membranes. Immunity is expressed in heightened resistance to mucosal invasion by L1 larvae, and the change in structure is evident in
The biology of sialic acids has been an object of interest in many models of acquired and inherited skeletal muscle pathology. The present study focuses on the sialylation changes in mouse skeletal muscle after invasion by the parasitic nematode Trichinella spiralis (Owen, 1835). Asynchronous
