In addition, 250 market pigs from bc>th slaughter houses were also randomly oc1]eoted and studies the lungs and sea by the methcds of thology, serology and direct fluorescent antibody technic (DFAT) in order to compare their accuracy for the detection of mycoplasrnal pneumonia, 110 out of 250 cases (44%) revealed the lesions U]fl1[1fl7 confirmed microscopically. 109 of examined samples were deteote antigens in lungs by DFAT, of which, 97 were sen with lesions of mycoplasmal pneumonia. The antibcdy-po€itivera were shown 39.2% (981250) of IHA and 34.4% (8&250)of CF test. Amongthem, 91 with lHAantibodyandallwithCFantibodycases werealso sscciati with lesions of mycoplasinal pneumonia in lungs.
