Abstract :
Foot and Mouth Disease (FMD) is one of the highly contagious diseases of domestic and wild animals of many countries of the world including Bangladesh. The present study was undertaken to detect currently circulating FMD virus (FMDV) in Bangladesh using BHK-21 cell line, and the FMDV were typed using RT-PCR. The viruses induced characteristics cytopathic effects in BHK-21 cell lines, for examples, rounding, swelling, breaking down of intercellular bridge and cell death. Out of 151 clinical samples collected from different districts of Bangladesh, 85(56.29%) were successfully adapted in BHK-21 cell line, and were analyzed using FMDV type specific primers. Among these 85 BHK-21 adopted virus, 71(83.52%) were found as positive for FMD virus by RT-PCR; of which, 31 (36.47%) were positive for type A, 26 (30.58%) for type O, and 10 (11.76%) for type Asia 1. Only 4 (4.70%) samples were found as positive for mixed infection having Type A and Asia 1 FMDV. All the FMDV originated from Tangail (n=7) and Rajshahi (n=6) districts were found as positive for FMDV while 71.42% (n=14/36) samples of Mymensingh district were positive for FMDV. The FMDV identified in this study could now be used for effective vaccine development to control the disease in Bangladesh.
