Isolation and Molecular Characterization of Mycoplasma gallisepticum and Mycoplasma synoviae in Chickens in Sudan.

The current study described the isolation and molecular detection of Mycoplasma gallisepticum (Mg) and Mycoplasma synoviae from tracheal swabs of diseased birds showing signs of respiratory distress in selected commercial (layer and broiler) farms and from yolk and an open air of pens of vaccinated breeder flocks in Sudan. A number of 45 Mycoplasma isolates were recovered from chickens in Khartoum, Gezira, and Equatoria states in Sudan. Of these, eight Mg and three Ms isolates were identified using growth inhibition and rapid serum agglutination (RSA) tests.
