How do you identify, isolate, and treat an active outbreak of Mycoplasma Synoviae (MS) causing joint issues and eggshell apical abnormalities in brown layers?

Mycoplasma Synoviae (MS) is a highly infectious pathogen that presents in two distinct clinical forms in brown layers: subclinical respiratory infection leading to swollen hocks, footpads, and infectious synovitis, and a newer, destructive syndrome known as Eggshell Apical Abnormality (EAA). MS causes severe inflammation in the shell gland, disrupting the deposition of the crystalline shell layer specifically at the egg apex (tip), resulting in a distinct zone that is glassy, thin, rough, and highly prone to cracking. To manage an active outbreak, immediately isolate the infected rows or sheds. Veterinary staff must treat the entire flock via drinking water with targeted antimycoplasmics, such as tylosin, tilmicosin, or tiamulin, for 5 to 7 days, paired with dietary chlortetracycline. Complete eradication requires deep disinfection of equipment between production cycles. Diagnostic pathology is detailed in the Poultry Encyclopedia, diagnostic PCR kits and specialized antimycoplasmic agents are sold on Poultry Plaza, daily live bird rates are on Poultry Rates, and MS-free certified flocks are traded on Murghi Mandi.
