Streptococcus suis is regarded as one of the major pathogens of pigs while S. suis type 2 (SS2) is considered to be a zoonotic bacterium for its ability to cause meningitis and streptococcal toxic shock-like syndrome in humans. Many bacterial species contain genes encoding serine/threonine protein phosphatases (STP) responsible for dephosphorylation of their substrates in a single reaction step. This study was aimed to investigate the role of stp1 in pathogenesis of SS2. An isogenic stp1 mutant (Δstp1) was constructed from the SS2 strain ZJ081101...

The excessive production of reactive oxygen species (ROS) and endoplasmic reticulum (ER) stress mediated responses are critical to embryonic development in the challenging in-vitro environment. ROS production increases during early embryonic development with the increased protein requirement for cell survival and growth. The endoplasmic reticulum (ER) is a multifunctional cellular organelle responsible for protein folding, modification, and cellular homeostasis. ER stress is activated by a variety of factors including ROS, leading to activation of the adaptive unfolded protein response (UPR), which restores homeostasis...

Porcine reproductive and respiratory syndrome virus (PRRSV) has a high degree of genetic variation. Here, we characterized the genetic variation and evolutionary relationships among circulating PRRSV strains in Southern China. In this study, we analyzed 29 NSP2 strains and 150 ORF5 strains from clinical samples collected in Southern China during 2007-2014. The alignment results showed that the nucleotide identities of the two genes among these strains were 80.5-99.7% and 80.9-100%, respectively. Phylogenetic analysis based on NSP2 gene showed that high pathogenic PRRSV were still the dominant virus in Southern China from 2013 to 2014...

Specific anti-venom used to treat scorpion envenomation is usually obtained from horses after hyperimmunization with crude scorpion venom. However, immunized animals often become ill because of the toxic effects of the immunogens used. This study was conducted to evaluate the toxic and immunogenic activities of crude and detoxified Tityus serrulatus (Ts) venom in sheep during the production of anti-scorpionic anti-venom. Sheep were categorized into three groups: G1, control, immunized with buffer only; G2, immunized with crude Ts venom; and G3, immunized with glutaraldehyde-detoxified Ts venom...
