**7.6 Diagnosis**

Isolation and identification of the samples of yolk, joints, and internal organs from the infected bird should have to be practiced. Bacteria are harvested on the blood agar from the sheep or bovine and results are visible within a day of incubation. Selective media for this organism can be used as mannitol salt agar [87–89]. Serology testing includes microtiter plate agglutination assay and indirect immunofluorescent antibody titer assay. It can be differentially diagnosed from the diseases of the joints of the poultry [79, 83].
