Histological studies on the development of porcine tonsils after birth.

Tonsils form the topographically first immune barrier of an organism against the invasion of pathogens. We used histology to study the development of tonsils of pigs after birth. At birth, the tonsils consist of diffuse lymphoid tissue without any lymphoid follicle aggregations.

The effect of meat processing methods on changes in disulfide bonding and alteration of protein structures: impact on protein digestion products.

We investigated the effects of different pork preparation methods (cooked pork, emulsion-type sausage, dry cured pork, and stewed pork) on protein structures and digestion. Compared with raw meat, processed meats contained lower levels of free sulfhydryl groups ( < 0.05).

Seasonal variation in the biocontrol efficiency of bacterial wilt is driven by temperature-mediated changes in bacterial competitive interactions.

Microbe-based biocontrol applications hold the potential to become an efficient way to control plant pathogen disease outbreaks in the future. However, their efficiency is still very variable, which could be due to their sensitivity to the abiotic environmental conditions.Here, we assessed how environmental temperature variation correlates with ability of , an endophytic bacterial biocontrol agent, to suppress the pathogen during different tomato crop seasons in China.
