Evaluation of 3ABCFMD Specific Immunity versus Clinical Infection among Cattle in Diyala Province

Background and Objectives The study was carried out to determine FMD specific antibodies in cattle using 3ABC ELISA in different age groups in Diyala province. Methods Ninety two local breed cattle of different ages and of both sexes, were ran-domly selected, include 21 males and 71 females ( 24 pregnant and 47 non-pregnant). Blood samples were collected and sera were separated. Serum samples were exam-ined by CHEKIT 3 ABC Enzyme Linked Immunosorbent Assay. Results The results revealed that the overall percentage of 3ABC FMD specific antibodies in cattle was 16.3 %. Higher percentage (18.3 %) and low in male (8.76 %). There was no significant difference between different animals status and no signifi-cant difference among regions. The highest percentage of 3ABC positive cases was recorded in adult cattle (more than 3 years) 25.53 % and lowest percentage (3.33 %) in age group of (1-2 year). There is a significant difference (P
