How is chancre caused?

The pathogenic bacteria of chancre is Haemophilus dukley, and this bacteria is gram negative Brevibacterium. The route of infection is sexual contact. Pathogenic bacteria invade through small local tissue damage. Bacteria often exist in macrophages and neutrophils in the affected area. The pathogenesis of genital ulceration is still lack of research. Occasionally there is non sexual contact, the pathogen invades through the pudendal part and produces chancre outside the pudendal part.

Damp heat, dirty sexual intercourse, or unclean vulva, dirt immersion, damage to the penis, external exposure to poison evil; Or element body dampness is exuberant, dampness evil is stagnant, stagnant for a long time turns heat, so that dampness heat toxin evil is poured into front Yin, hair is chancre. Toxic heat contains desire to burn, excessive indulgence or no discharge of essence, stagnated essence and turbid blood in the stem; Or take hot medicine for a long time, fire depression in the inside, depression fire into poison, along the meridian outside the former Yin

After contact with the pathogen, a small inflammatory papule or pustule appeared at the infected site, and then it quickly became pustule. After 3-5 days, the damage continued to invade the affected area, forming a deep ulcer with severe pain. Ulcer is round or oval, soft texture, easy to bleed, rough and irregular edge. The surface is covered with malodorous yellowish gray exudate.
