동물(젖소)건강 Monitoring System 모델 개발 V. 유우의 사육규모에 따른 Salmonella spp., Escherichia coli O157:H7 및 Listeria monocytogenes의 분리 빈도

Development of a Model for Animal Health Monitoring System V. Iso1ation Frequence Of Salmonella spp., Escherichia O157:H7 and Listeria monocytogenes from Dairy Cow with different herd size

  • 발행 : 2000.12.01

초록

The present study conducted to evaluate the isolation frequency of Salmonella sap., Escherichia O157:H7 and Listeria monocytogenes in fecal samples collected form 33 dairy cow feedlots in West Gyeong-nam province from tan. 179\ulcorner to Feb. 1999. Salmonella spp. were isolated from 8.7% of fecal samples and 57.5% of dairy cow feedlots participaiting in this study had at least one positive fecal 7ample. The isolation rates of Salmonella spp. in each herd size were 42.9% in ln less than 125 heads, 63.6% in 25% to 50 heads and 75% in more than 50 heads. Of the positive sample, the most common serogroup recovered was Bl(31.5%), followed by C1 and D(22.9%), C2(16.2%), A(4.2%) and E(2.1%), in order. However, E. coli O157:H7 and Listeria monocytogenes were net detected in the fecal samples collected from all feedlots.
