Hatcheries' contamination: the molecular characterization and pathogenicity of Mycoplasma gallisepticum isolates in China.

ABSTRACT: Mycoplasma gallisepticum (M. gallisepticum) is a significant pathogenic microorganism contaminating poultry hatchery environments. During intensive hatching, M. gallisepticum significantly impairs embryonic health and development, ultimately reducing embryonic vitality. Clinically, it is common for affected embryos to exhibit incomplete pipping of eggshell, a condition referred to as pipping failure embryos (PFEs). Critically, live PFEs exhibit high M. gallisepticum shedding, substantially increasing the risk of M. gallisepticum transmission to healthy chicks at early-stage within the same space. These asymptomatic infected chicks often develop chronic respiratory disease (CRD) under stress during subsequent growth. This study investigated M. gallisepticum contamination in hatchery environ
