Rodents and ticks as a reservoir of mycoplasmas in poultry farms.
The role of rodents and ticks in the transmission of mycoplasmas was studied in upper Egypt. Of 50 rats [Rattus sp.] trapped on a poultry farm in Assiut Province, 14 isolates were recovered and identified as either Mycoplasma gallisepticum or M. neurolyticum. Examination of larvae, eggs and nymphs of Argas persicus collected from the walls, cracks and crevices of poultry housing revealed 40 isolates of M. gallisepticum and M. meleagridis.
