Nasal immunization with homogenate and peptide antigens induces protective immunity against Trichinella spiralis.

Mice were successfully immunized against the intestinal nematode Trichinella spiralis by intranasal administration of a 30-mer peptide antigen with cholera toxin B. Immunized mice developed antigen-specific serum immunoglobulin G1, intestinal immunoglobulin A, and a type 2-biased cytokine response. Intranasal immunization therefore generates the Th2-mediated responses required for immunity agai...

Protective Immunity against Trichinella spiralis Infection Induced by a Multi-Epitope Vaccine in a Murine Model

Trichinellosis is one of the most important food-borne parasitic zoonoses throughout the world. Because infected pigs are the major source of human infections, and China is becoming the largest international producer of pork, the development of a transmission-blocking vaccine to prevent swine from being infected is urgently needed for trichinellosis control in China. Our previous studies have d...

Heterologous Prime-Boost Vaccination Enhances TsPmy’s Protective Immunity against Trichinella spiralis Infection in a Murine Model

TsPmy is a paramyosin expressed by parasitic Trichinella spiralis and confers a protective immunity when its recombinant protein or DNA was used as an immunogen. To improve its immunogenicity and vaccine efficacy, we conducted a heterologous prime-boost strategy by orally delivering one dose of TsPmy DNA carried by attenuated Salmonella typhimurium (SL7207), followed by two doses of recombinant...

Vaccination with a Paramyosin-Based Multi-Epitope Vaccine Elicits Significant Protective Immunity against Trichinella spiralis Infection in Mice

Trichinellosis is a worldwide zoonosis and remains a serious public health problem. Interrupting parasite transmission via vaccination of livestocks with a potent vaccine is a practical approach to prevent human Trichinellosis. Our previous studies have identified that paramyosin of Trichinella spiralis (Ts-Pmy) is a good vaccine candidate against Trichinellosis. In this study, a novel multi-ep...

Oral Vaccination with Attenuated Salmonella typhimurium-Delivered TsPmy DNA Vaccine Elicits Protective Immunity against Trichinella spiralis in BALB/c Mice

BACKGROUND Our previous studies showed that Trichinella spiralis paramyosin (TsPmy) is an immunomodulatory protein that inhibits complement C1q and C8/C9 to evade host complement attack. Vaccination with recombinant TsPmy protein induced protective immunity against T. spiralis larval challenge. Due to the difficulty in producing TsPmy as a soluble recombinant protein, we prepared a DNA vaccine ...
