DGGE analysis of the PCR products of lactic acid bacteria present in the neonatal Thoroughbred feces by lactic acid
bacteria-specific primers [25]. Approximately 200 bp 16S rDNA of E.
coli No. 341–534 were amplified by PCR. Lane 1: meconium, lane 2: feces obtained on the 7th day after birth, lane
3: feces obtained on the 14th day after birth, lane 4: feces obtained on the 21st day after birth. Band a: L.
johnsonii (100% similarity), band b: L. equi (100% similarity), band c: L.
ruminis (99.9% similarity), and band d: L. reuteri (99.8% similarity).
