Protective immunity against Trichinella spiralis in mice elicited by oral vaccination with attenuated Salmonella-delivered TsSP1.2 DNA.

Trichinellosis is a worldwide important food-borne zoonosis caused mainly by ingesting raw or undercooked pork infected with Trichinella spiralis larvae. The development of vaccine is needed for preventing swine from Trichinella infection to ensure pork safety. Previous studies showed that T.

Screening and characterization of early diagnostic antigens in excretory-secretory proteins from Trichinella spiralis intestinal infective larvae by immunoproteomics.

The excretory-secretory (ES) antigens from Trichinella spiralis muscle larvae are the most commonly used diagnostic antigens for trichinellosis, but specific IgG antibodies were not detected in early stage of infection. The aim of this study was to identify early diagnostic antigens from ES proteins of intestinal infective larvae (IIL), the first invasive stage of T. spiralis.

Complete mitochondrial genome of a German Shepherd (Canis lupus familiaris breed German Shepherd) provides insights into genome-wide sequence variations.

In this work, we report the complete mitochondrial genome sequence of a German shepherd. The total length of the mitogenome was 16,727 bp. It contained the typical structure of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a non-coding control region (D-loop region).

[Studies on functional genes of Chinese herbal medicine].

In order to establish the foundation for modernization of Chinese herbal medicine, discovery of the functional genes related with the bioactive components of Chinese herbs and the rules of their expression was progressed for determining the regulatory mechanism, obtaining the core metabolic pathway and key regulatory factors of the medicinal components synthesis. In this article, the studies about plant's functional genes at home and abroad was introduced in three aspects: the pattern plants (rice, thaliana, etc.), the main technologic strategy (gene expression differentia, sequential tag of gene expression, DNA microarray technique and gene expression sequential analysis) and bio-informative method (comparative genomics).
