Abstract

Seroprevalence Mycoplasma synoviae infection was carried out in male and female breeder flocks as well as commercial layer flocks by ELISA antibody (Idexx Laboratories USA) testing kit for M. Synoviae. The birds from few healthy flocks were also tested for MS antibody. A total of 134 serum samples were collected from ten different male parent flocks showing signs of lameness due to tenosynovitis out of which 95 serum samples (70.90%) were positive for MS antibodies. The overall mean titre, titre range and coefficient of variation (CV) from male broiler parent (BP) flocks were 4123, 0 to 8130 and 70.1, respectively. Moreover, total of 126 serum samples were collected from twelve female BP flocks out of which 66 serum samples (52.38%) were positive for MS antibodies. The overall mean titre in female BP flocks was 2351 with a CV of 100.4. The titres of these flocks were ranged from 11 to 7056. The overall mean titre in two commercial layer flocks was 9381 with a titre range of 3693 to 16291 and a CV of 42.3. However, all the serum samples collected from different healthy flocks were negative for MS antibodies.
