Efficacy of flouroquinolone [Pefloxacin] on mycoplasma infection in chickens

The efficacy of the newer flouroquinolone [pefloxacin] given alone or in-combination with levamisole against Mycoplasma gallisepticum [MG] in experimentally infected chickens was investigated. Two hundred one day old chicks were used. The use of levamisole as a non-specific immunostimulant with pefloxacin 10 mg/kg body weight showed good curative effect which was indicated by decrease in mortality rates, increase in the body weight gain, high feed conversion as well as low rate of re-isolated MG and low titre in HIT as compared with those received pefloxacin alone 10 mg/kg body weight or levamisole 2.5 mg/kg body weight alone
