Feeding Eucommia ulmoides extract enhances protection against high-temperature stress in chicks.

Chick's susceptibility to heat stress often leads to growth retardation, immune function impairment, disease, and mortality. This thesis explores the potential ameliorative effect of 0.8% Eucommia ulmoides extract (EUE) into the diet of heat-stressed chicks in a 15-d feeding trial.

Overexpression of the NbZFP1 encoding a C3HC4-type zinc finger protein enhances antiviral activity of Nicotiana benthamiana.

Viral diseases are crucial determinants affecting tobacco cultivation, leading to a substantial annual decrease in production. Previous studies have demonstrated the regulatory function of the C3HC4 family of plant zinc finger proteins in combating bacterial diseases. However, it remains to be clarified whether this protein family also plays a role in regulating resistance against plant viruses.

Isolation and In Vitro cultivation of Lawsonia intracellularis from China.

Lawsonia intracellularis is an obligate intracellular bacterium that cannot be cultured by conventional bacteriological methods. Pigs infected with L. intracellularis suffer from decreased daily weight gain and poor feed conversion ratio.

Preparation and Characterization of a New Monoclonal Antibody Specific Against and Its Application in Indirect Immunofluorescence and Immunocytochemistry Assay.

Proliferative enteropathy (PE) is an infectious enteric disease caused by () and is endemic in pig herds worldwide. However, a -specific monoclonal antibody plays an important role in the evaluation of infection . Therefore, the objective of this study was to produce and identify the characteristics of a new monoclonal antibody against the outer membrane protein (Omp2) of and apply it in an indirect immunofluorescence assay (IFA) and immunocytochemistry (IHC).

Dietary Extract Alleviates the Effect of Cold Stress on Chick Growth Performance, Antioxidant and Immune Ability.

This study aimed to investigate the protective value of extract (EUE) on chicks under cold stress. A total of 21 compounds were identified in EUE using mass spectrometry (LC-MS). Ninety chicks were divided into a control group (CS) fed a basal diet and an experimental group supplemented with EUE, exposed to 10 ± 1 °C for 8 h per day.

Evaluation of immune efficacy of Omp2 protein against Lawsonia intracellularis in mice.

Porcine proliferative enteropathy (PPE) is caused by the obligate intracellular bacterium Lawsonia intracellularis. Infection results in an enteric disease characterised by decreased growth performance of pigs, and presents a major economic burden for swine industries worldwide. Since vaccination is an effective technique for controlling PPE, novel effective vaccine platforms are need to be developed.

Coinfection with porcine circovirus type 2 and Streptococcus suis serotype 2 enhances pathogenicity by dysregulation of the immune responses in piglets.

Porcine circovirus type 2 (PCV-2) and Streptococcus suis (S. suis) are common pathogens in pigs. Both pathogens are associated with the porcine respiratory disease complex.
