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)
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.
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)
The authors describe the results of studies carried out in rabbits infected with syphilis on the therapeutic properties and duration of penicillinaemia of a number of penicillin preparations manufactured in the USSR and of certain others from Czechoslovakia and the USA. These products were studied after intramuscular administration, mainly in doses of 42(More)
