Syphilis is the infectious disease that named "great imitator" because can imitate manifestations of other diseases and can involve any organ in body. Late manifestations of syphilis in cardiovascular system and central nervous system (eNS) are important. A case of huge syphilitic aortic aneurysm who visited in Shahid Rajai Hospital, is being reported. The Patient underwent surgery under genera...
OBJECTIVE To study ultrastructural aspects of infection with Treponema pertenue (Pariaman strain), originating from West Sumatra, Indonesia. MATERIALS AND METHODS Biopsy material originating from skin lesions in ten young children suffering from early infectious yaws in Indonesia, and rabbit testicular tissue inoculated with T pertenue. Human skin as well as rabbit testicular tissue was exami...
The outer membranes from Treponema pallidum subsp. pallidum and Treponema vincentii were isolated by a novel method. Purified outer membranes from T. pallidum and T. vincentii following sucrose gradient centrifugation banded at 7 and 31% (wt/wt) sucrose, respectively. Freeze fracture electron microscopy of purified membrane vesicles from T. pallidum and T. vincentii revealed an extremely low de...
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.
Virulent Treponema pallidum has been shown to consume O(2) at a rate similar to that of the known aerobic spirochaete, Leptospira. Such O(2) uptake is cyanide sensitive, indicating a functioning cytochrome oxidase. Inhibition of O(2) uptake by azide, chlorpromazine, and amytal further suggests a functioning electron transport system for the oxidation of nicotinamide adenine dinucleotide (reduce...
Syphilis is a sexually transmitted infection caused by the spirochete Treponema pallidum. Ocular involvement can occur at any time, and it may affect 10% of patients in secondary stage, from 2% to 5% tertiary stage. Uveitis most common presentation ocular syphilis, affecting 0.4% 8% with systemic disease. Chorioretinitis posterior alteration. We present case 53-year-old male patient, presenting...
