This case was found in Holstein cow suffering from dystocia. The twin calves in uterus were dead and removed by fetotomy. Gross anatomical analysis of thoracopagus siamese calf was carried out. Two normal heads were present on two necks, however, the twins were fused in the thoracic region. There were four forelimbs and an abnormal orientation of ribs. Two separate vertebral columns along the length of the animal ended with two tails. A single pericardium lay on the midline when opening the thorax.

Shiga toxin (stx) producing Escherichia coli (STEC) causes various clinical signs in animal and himan. In this study, 255 fecal samples from samples from calves showing diarrhea were collected from cattle farms in Chonnam province during the period from January 2005 to July 2005. Twenty six STEC (10%) were isolated from 255 fecal samples by PCR. The isolates displayed three different stx combinations (stx1[69%], stx1 and stx2 [15%], and stx2 [38%]). The isolates were further studied for virulence associated genes and antimicrobial resistance to define the virulence properties.
