Abstract

SUMMARY

Twenty colonies from each of 27 randomly selected primary cultures of cholera vibrios on bile-salt agar were investigated. All of the individual colonies comprised cholera vibrios that would be labelled as but they varied in their sensitivity to polymyxin. In 10 of the primary cultures, all of the colonies were of vibrios resistant to polymyxin B, and in another nine cultures all the colonies proved to be of organisms sensitive to the antibiotic. The remaining eight primary cultures were found to be mixtures of sensitive, partially sensitive and resistant colonies. The fact that all the individual colonies in the primary cultures examined were found positive for haemagglutination and resistance to cholera group-TV phage irrespective of their pattern of polymyxin sensitivity indicates that these two characters are not linked with resistance to polymyxin B.
