Abstract | ||||
The pathogenicity of Aeromonas hydrophila to embryonated chicken eggs (ECE) at different ages of incubation was studied. Infected 5 and 17-day-old ECE revealed mortality and hatchability rates renged between (36.7 % and 30 %) and (63.3% and 70 %) respectively. Acidic and alkaline disinfectants (Aldekol GDA and Virkon-S) were used to control of Aeromonas hydrophila infection of these ECE that proved improvement in the rate of hatchablity reaching (80 % and 86.6 % ) and (76.6 % and 83.3 %) respectively. Post- mortem lesions as well as bacterial reisolation from dead embryos as well as hatched chicks were discussed in details. | ||||
