Avian pathogenic (APEC) is an important bacterial pathogen that causes severe respiratory and systemic infections in poultry. Our previous research investigated the prevalence and antimicrobial resistance phenotypes of APEC isolated from poultry flocks in Jiangxi Province, China. The present study aims to further identify the serotypes and the carbapenem-resistant gene in APEC strains.

- Poultry farming is widespread but threatened by pathogenic bacterial infections, particularly those resistant to antibiotics, highlighting a significant issue in meat production.
- A study in Jiangxi Province, China, analyzed bacterial pathogens from diseased poultry, revealing a 62.90% isolation rate with major pathogens like avian pathogenic E. coli (APEC) and Salmonella spp.
- APEC isolates exhibited high levels of antimicrobial resistance, with many resistant to multiple drug categories, indicating an urgent need for better disease management in poultry to combat emerging antimicrobial resistance (AMR).
Avian leukosis virus (ALV) induces multiple tumors in chicken and is still prevalent in a lot of local flocks in China. In this study, we analyzed the ALV infection status in an Anyi tile-like gray chicken flock by DF1-cells isolation, virus identification, and genome sequencing. Results showed a 29% (29/100) ALV positive rate in this flock.

In this study, 672 samples of fresh meat (pork, 347; chicken, 196; and duck, 129) were collected from retail markets in different provinces of China from 2010 to 2014. We identified 10 different serotypes among 80 isolates, whereas 12 isolates were nonmotile precluding conventional identification of complete serotype.

Aim: To prepare monoclonal antibodies (mAb) against the hemagglutinin(HA) of H9 subtype of avian influenza virus (AIV).
Methods: 8 week-old female BALB/c mice were immunized with the inactivated vaccine of H9 subtype of AIV. Splenocytes from the immunized mice were fused with Sp2/0 myeloma cells, and positive hybridoma clones were screened by indirect ELISA and hemagglutination inhibition test (HI).
