Under the scanning electron microscope, the body surface of trichomonads appears ruffled and creased, with numerous crater-like depressions, which should probably be interpreted as the initial stage in the formation of digestive vacuoles or pinocytotic vesicles. Having contacted epithelial cells, trichomonads engulf them totally or partially. Various(More)
In previous papers* the main features of gonococcal structure as seen under the electron microscope were described. The study of gonococci taken from a culture on artificial medium is undoubtedly of importance, since it gives an idea of the structure of the pathogen outside the patient's organism and unaffected by exposure to the body's protective forces.(More)
Penicillin is an excellent remedy for syphilis. The speed with which the treponemes disappear from primary lesions and the way in which clinical manifestations resolve and serological tests become negative in many patients have raised hopes of a complete and rapid cure for syphilis, and in some quarters have even inspired hopes of complete eradication of(More)
Ultrathin sections of a rabbit scrotal syphiloma were examined by electron microscopy. Treponemes were observed in the endo-, peri-, and epineurium of the nerve fibre. The significance of these findings, in that infection may be transmitted via the nerve fibres and pain reduced by damage to the afferent fibres, are discussed.
