Antibiotic susceptibility and toxin production of Escherichia coli isolated from diseased domestic animals
환축에서 분리한 대장균의 항균제 감수성 및 독소생산능
Abstract
The present study was carried out to investigate the biochemical characteristics, antibiotic susceptibility and toxin(ST, LT, VT1.2 type) production test of 60 Escherichia coli isolated from diseased domestic animals in southern area of Kyungbuk province from April to December 1997. 1. The biochemical and cultural reaction were consistent with the classification criteria of Edwards and Ewing. 2. In antibiotic susceptibility test, 60 E coli showed highly susceptible to CL(96.7%), XNL(86.7%), AN(81.7%), SXT(61.7%), Lin(55%), GM(53.3%), KM(41.7%), N(41.7%), ENR(40%), AM(40%), CF(30%), 5(13.3%) and Te(11.7%), in order. 3. Sixty E coli isolates were multiful resistant to seven or more antibiotics incombination. 4. Three strains for 60 E coli were detected heat-labile enterotoxin(LT) and that's titers were 2, 8 and 16, respectively.
