Abstract
Summary
Fusion of E. coli cells and spheroplasts, B. megaterium cells and protoplasts, and M. laidlawii by UV-inactivated Sendai virus could not be demonstrated by direct methods or indirectly by recombination analysis. Studies show that E. coli cells and spheroplasts adsorb, in contrast to HeLa cells, only small amounts of Sendai virus, indicating that fusion may be blocked at the adsorption stage. The NANA in E. coli appears to be inaccessible to the virus neuraminidase.
