Prevalence of Mycoplasma gallisepticum and Mycoplasma synoviae Antibodies in Free Range Chickens as Detected by ImmunoComb Assay

Abstract

This study was conducted to detect the antibody titer Mycoplasma gallisepticum and M. synoviae on the free-range chicken project at the Tarlac Agricultural University and its beneficiaries in Santa Ignacia. A total of 110 blood samples from free-range chickens were collected, regardless of age, sex, and breed. These samples were tested for Mycoplasma infection using the ImmunoComb Assay.

Results showed that 56.4% were found positive for Mycoplasma synoviae and 46.3% positive for Mycoplasma gallisepticum. However, even though they were found positive, the antibody titer for Mycoplasma synoviae was only 1.82 ImmunoComb® unit in Tarlac Agricultural University – FRC Project, and 1N.34 ImmunoComb® unit in Santa Ignacia FRC beneficiaries. This finding indicate weak positive. Further, Mycoplasma gallisepticum with 1.40 ImmunoComb® unit in Tarlac Agricultural University – FRC Project, and 1.11 ImmunoComb® unit in Sta Ignacia FRC beneficiaries were found to be weakly positive. Based on the results of the study, the Mycoplasma gallisepticum and Mycoplasma synoviae tested were both prevalent but in low antibody titers on the Freerange Chicken project at Tarlac Agricultural University and its beneficiaries in Santa Ignacia.
