Riemerella anatipestifer (R. anatipestifer, RA) is the etiological agent of duck serositis, an acute multisystemic disease in ducks that is globally distributed and causes serious economic losses in the duck industry. Despite exhibiting multidrug resistance, the transmission mechanism of its antibiotic resistance genes (ARGs) remains incompletely identified.

Article Synopsis
- Ducks in Thailand are affected by duck circovirus (DuCV), leading to symptoms like feather abnormalities, weight loss, and poor growth, prompting a study to investigate the presence and genetic characteristics of the virus in local flocks.
- Tissue samples from affected ducks were collected for histopathological examination and molecular analysis to confirm DuCV infection and check for coinfections with other pathogens.
- The study found that DuCV isolates from Thailand belong to genotype I, with sub-genotypes identified, and revealed genetic variations that correspond with other known infections, indicating a complex interaction with multiple co-infections in affected ducks.

(RA) is a significant poultry pathogen causing acute septicemia and inflammation. The function of protease RAYM_01812, responsible for gelatin degradation, is unexplored in RA pathogenesis. To elucidate its role, we generated a deletion mutant ΔRAYM_01812 (ΔRAYM) and complementary CΔRAYM_01812 (CΔRAYM) strain and revealed the protease's role in extracellular gelatinase activity.

The Riemerella anatipestifer bacterium is known to cause infectious serositis in ducklings. Moreover, its adherence to the host's respiratory mucosa is a critical step in pathogenesis. Membrane cofactor protein (MCP; CD46) is a complement regulatory factor on the surface of eukaryotic cell membranes.
