THIN SECTIONS OF DIVIDING NEISSERIA GONORRHOEAE

Fitz-James, Philip (University of Western Ontario, London, Ontario, Canada). Thin sections of dividing Neisseria gonorrhoeae. J. Bacteriol. 87:1477-1482. 1964.-The fine structure of the gram-negative pathogen Neisseria gonorrhoeae is described. Its cell-wall and membrane structures are not unlike those of Escherichia coli, possessing periodic points where wall and membrane are approximated. It appears to divide by a process of unequal constriction plus septum formation, preceded by a loop of membrane. Mesosomes are also seen but in the cell periphery away from the division plane. At some of the wall-membrane junctions, the cell wall appears to arise out of the membrane.
