Detection of different bacteria causing decreased hatchability in turkey ecgs

A total of 360 eggs collected from turkey farms, from low fertility and low hatchability, were examined for both Mycoplasma and egg borne bacterial diseases. Fresh fertile eggs revealed the recovery of Mycoplasma meleagridis [50%] and Salmonella typhimurium [20%]. From non-fertile eggs, Mycoplasma iowae [50%], Mycoplasma gallopavonis [25%] were isolated. No bacteria were recovered from the non-fertile eggs. From dead embryos several Mycoplasma species were isolated viz., Mycoplasma iowae [25%], Mycoplasma meleagridis [25%] and Mycoplasma gallopuvonis [25%]. Mixed infection with coliforms were isolated from all the internal contents of the eggs and dead embryos
