Studies on gonococcus infection. VI. Electron microscopic study on in vitro phagocytosis of gonococci by human leukocytes.
The ingestion of Neisseria gonorrhoeae by isolated human leukocytes in vitro has been studied by electron microscopy. Use of the modified critical-point drying method allows clear visualization of progressive ingestion of both pilated and nonpilated gonococci by leukocytes. Incomplete ingestion of pilated gonococci with protrusion of tangled masses of pili from sites of phagocytosis are also found.
