dc.description.abstractMycoplasmosis is one of the important diseases of exotic and local poultrybreeds in Nigeria. The disease causes decreased feed efficiency, poor carcass quality and sub-optimal egg production in layers. Seroprevalence of Mycoplasma gallisepticum(MG) and M. synoviae(MS) infection in local chickens in three Local Government areas (L.G.A.) of Niger State was determined between August and December, 2010. A total offive hundred and fifty two blood samples were collected. Serum plate agglutination (SPA) test and a combined MG/MSEnzyme-linked immunosorbent assay(ELISA)techniques were used to determine the presence of antibodies against M. gallisepticum and M. synoviae. The overall seroprevalence of MG was 85.86%, while the prevalence for MS was 79.71% with SPA test. The ELISA gave a seroprevalence of 91.84% for both MG and MS. There was highly significant difference (P<0.001) between the mean red blood cell (RBC), haemoglobin (Hb) and packed cell volume (PCV)(3.28 ± 2.23×106/ml, 14.45 ± 7.85g/dl, 44.85 ± 30.15%,respectively) of the chickens affected by MG and MS in Kontagoraand the corresponding mean RBC, Hb and PCV (2.36 ± 1.55×106/ml, 12.6 ± 7.65g/dl, 32.05 ± 23.85%, respectively)in Minna. The results of the serum biochemistry obtained during this study were lower than the reports of previous works by Durotoyeet al. (2000) but similar to the report of Ladokunet al.(2008) who also reported serum total protein range of 4.63 - 4.81 mg/dl, cholesterol 31.3 – 32.45mg/dl and albumin 3.28 - 3.48 g/dl in Nigerian chickens. Thehistopathological changes of some lung tissues collected from apparently healthy chickens revealed varying degrees of cellular infiltrations in the lungs. It was concluded thatM. gallisepticum and M. synoviaeare in circulation among local chickens in three Local Government Areas surveyed and they could serve as major reservoirs of these organisms in Niger State and in Nigeria as a whole.en_US
