32 strains were untyped from quails and wild The total incidence percentage of mycoplasma birds. Serodiagnosis by using ELISA test for bothsera and egg yolk of quails had no any detectable which isolated from living quails was 5.75%antibody titres for both M. gallisepticum and M. while it was 3.75% in dead ones, although total recovery rate in dead in sheel cggs was 10% and synoviae. The results of scrodiagnosis of samples 6% in infertile quail eggs. Also the total recovery collected from living quails which were cxperi-rate of mycoplasma isolated from kestrel falcons mentally infected by M. gallisepticum S 6 strain was 28.75% and it was 30% in Black-shoulder and M. gallisepticum “ficld strain" under stress kite. On the other hand, the total incidence per- factors by both environmental and_ biological centage of mycoplasma isolated from Moorhen _ Stresses, proved that no detectable antibodics fowls was 12.5% and it was 20% in Doves. Bio- were present in their sera samples indicating that chemical tests for glucose and arginine were done these birds may act as reservoir for such myco- and the results were recorded. Serological exami nation was done by growth inhibition and growth precipitation tests which revealed that 23 strains plasma microorganisms.
