Xinjiang fine-wool sheep is an exclusive breed for wool in China, which has excellent stress tolerance. In this study, we collected feces and blood samples of 20 Xinjiang fine-wool sheep under the same genetic characteristics, the Fine-Wool Sheep (FWS) group and the Control Fine-Wool Sheep (CFWS) group were set up according to the differs in phenotypic characteristics of their wool.

The rapid evolution of multidrug-resistant and the fact that there is no currently licensed effective vaccine against warrant the need for vaccine development. Reverse vaccinology (RV), which involves screening a pathogen's entire genome and proteome using various web-based prediction tools, is considered one of the most effective approaches for identifying vaccine candidates.

The infection status of gastrointestinal parasites in camels () in the Tianshan Mountains pastoral area in China is still unclear. The aim of this study was to investigate the species and infection intensity of gastrointestinal tract parasites in local camels.

Materials And Methods: A total of 297 blood samples of pet dogs and 709 skin ticks () were subjected to molecular detection using PCR for 16S gene, and then, positive samples were amplified, sequenced, and phylogenetically analyzed for gene.
Introduction: type 3 (PCV3) is a newly discovered . The molecular characteristics and genetic evolution of PCV3 in Xinjiang province, China still being unclear, the aim of the study was their elucidation.
Material And Methods: A total of 393 clinical samples were collected from pigs on commercial farms in nine different regions of Xinjiang and phylogenetic analysis based on full-length genes was performed.
As an important zoonotic pathogen, has led to serious mastitis and endometritis in infected dairy cows. In this study, a total of 164 strains of were isolated from dairy cows in Xinjiang Province, China, and subjected to assays to determine drug susceptibility and biofilm (BF) formation ability. Enterotoxin-related genes were detected, and the transcription levels of genes related to BF formation were determined by using reverse transcription-quantitative polymerase chain reaction.

A survey on the infection and epidemic status of PoSaV in Xinjiang Province, Northwest China, was conducted in this study. We applied indirect viral protein 1 (VP1)-ELISA method to detect specific antibodies in 1218 serum samples of 3-month-old piglets collected from eight regions in Xinjiang during 2013-2014 and also detected PoSaV in 146 diarrhea stools of piglets in these eight regions using RT-PCR technology.

Mycoplasma pneumonia is one of the most important infectious diseases that threaten sheep production. In order to investigate the epidemic status of Mycoplasma ovipneumoniae infection in sheep, indirect hemagglutination assay was used to analyze 1679 serum samples collected from four different breeds of sheep (Kazak sheep, Hu sheep, Merino sheep, and Duolang sheep) in six regions in Xinjiang between 2012 and 2014. One thousand one hundred sixty-nine sheep nasal swabs and 180 lungs were PCR analyzed.

Objective: To study the effect of RsbV gene deletion on the virulence of Listeria monocytogenes.
Methods: The fragment with RsbV deletion was generated by gene overlap extension PCR (SOE-PCR) and the mutant with RsbV deletion was obtained by homologous recombination based on the wild strain LM-XS5. The differences in virulence between the two strains were determined by LD50, bacterial counts in liver and spleen, and qRT-PCR experiments.

Purpose: Akabane disease characterized mainly by fetal damage is a ruminant disease caused by insect-transmitted Akabane virus infection.
Methods: We investigated Akabane disease using serum neutralization tests in 446 blood samples collected from 187 cattle and 259 sheep of Xinjiang province, northwest China.
Results: (1) The overall prevalence rate of neutralizing antibody was 19.
