hard bump that enlarges and breaks down. extremely infectious. persists for 2-6 weeks then
suddenly goes away
Secondary Syphilis - ANS 3 weeks to 6 months after chancre heals. fever, headache, sore
throat followed by lymphadenophathy and a peculiar red or brown rash that breaks out on all
skin surfaces, including palms and soles of feet. lasts a few weeks major complications: occur in
bones, hair follicles, joints, liver, eyes and brain can linger for months or years
Tertiary Syphilis - ANS many forms, many include heart, nervous system, or skin. gumma
formation (swollen tissue tumors) in tissues. 30% get to this stage, can last for 20 years
urethritis-gonorrhea - ANS in cervix in women and urethra in men. may spread to uterus and
fallopian tubes. can spread to joints. mouth if genital-oral contact. rectum. eyes of newborns

diagnosis - ANS -causative agent- Neisseria gonorrhoeae, gram negative, bean shaped -organ
effected- reproductive -transmission- sexual contact symptoms,- vaginal discharge, abdominal
pain, painful when urinating treatment-,antibiotics, complications- can spread to joints and be

, urethritis-chlamydia - ANS common term for urethra infection, discharge. caused by
Chlamydia trachomatis, q onlygrows intracellularlyin phagosome. most frequently reported
disease in US. same painful symptoms as gonorrhea but milder. can spread in same ways as
gonorrhea but the baby's eyes cannot be treated with silver nitrate. can also cause pneumonia
in new borns. treatment with azithrozymax, diagnosed by symptoms/history and looking at
specimen under flouresent light
Genital Herpes (STD) - ANS • Caused by Herpes simplex type 2 virus • 45 million Americans
infected • Periodic eruption of small, painfulblisters on genitals • Infection requires contact with
fluidfrom these sores. can be transmitted when no blisters • Antiviral drugs can reduce pain but
thereis no curecan go away for a while then come back. related to cervical cancer
