Electron microscopic study of phages and aberrant structures produced by induction of prophage kappa in Vibrio cholerae el tor cells. Indian Journal of Experimental Biology. 1993 Dec; 31(12): 955-62http://imsear.searo.who.int/handle/123456789/58331Prophage kappa in V. cholerae el tor strain SLH22(J) could be induced spontaneously or by treatment with nitrofurantoin, though the efficiency of induction was very low (not more than 0.8%). V. cholerae el tor cells were found to release many different aberrant structures of the temperate phage, kappa. These aberrant structures were characterized by density gradient centrifugation and electron microscopy.engBacteriophages --growth & developmentCentrifugation, Density GradientDefective Viruses --ultrastructureMicroscopy, ElectronVibrio cholerae --ultrastructureVirus ActivationJournal Article
