A.YR 1966 T1 The Action of Chloroform-killed Suspensions of Enteropathogenic Escherichia Coli on Ligated Rabbit-gut Segments JF Microbiology, VO 42 IS 2 SP 309 OP 313 DO https://doi.org/10.1099/13500872-42-2-309 PB Microbiology Society, SN 1465-2080, AB SUMMARY: Suspensions of enteropathogenic Escherichia coli and organisms of the same O-antigen group were tested for ability to cause dilatation of the ligated gut segment of rabbit small intestine. Suspensions treated with penicillin or by disintegration in a Mickle shaker were unsuccessful, since it was impossible to obtain sterile material. Suspensions killed with toluene did not cause dilatation, but chloroform-killed cultures did so when the living culture also gave a positive reaction, whereas chloroform-killed cultures of negative living strains were also negative. Chloroform-killed positive suspensions lost their gut-dilatation effect on keeping; this loss ran parallel to loss of esterase activity, though the esterase was not responsible for the dilatation effect., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/13500872-42-2-309
