چکیده

A study was conducted in buffaloes to detect the M. bovis in blood samples through PCR. The PCR assay was described which could detect M. bovis infection in blood samples that were apparently negative in PPD of tubercle bacilli. A total of 100 buffaloes blood samples were tested and 2.0 % buffaloes were found positive for M. bovis infection through single comparative cervical intradermal tuberculin test (SCCIDTT) while 54 % were found positive for M. bovis infection through PCR. The positive cases were analyzed in the background of their history. History revealed that these positive buffaloes were reared in a populated herd for a long time. This study provides an evidence of bovine tuberculosis caused by M. bovis in buffaloes which are main source of milk and meat is South Asia.

Development of one-tube multiplex polymerase chain reaction (PCR) for detecting Mycobacterium bovis

A multiplex PCR (m-PCR) with primers targeting the 16S rRNA, Rv3873 and a 12.7-kb fragment in the genomes of a Mycobacterium tuberculosis complex was designed for the differential diagnosis of M. tuberculosis, M. bovis, M. bovis BCG and non-tuberculosis Mycobacterium (NTM). The specificity of this assay was 100%, and the detection limit was 15 pg of genomic DNA. Of the 206 blinded clinical samp...
