If disease becomes systemic (moves away from reproductive tract), may move into blood, then joints, heart, liver.If untreated in women, sometimes causes pelvic inflammatory disease (PID), which may lead to sterility.Usually remains a local infection, causing little permanent damage.Symptoms in women (if any): inflammation of cervix, thick, yellowish discharge, possibly burning urination, cloudy urine.Symptoms in men: urethral discharge, burning urination, cloudy urine.

In men, it is most commonly a urethral infection in women, cervical or urethral.

Can be genital, anal/rectal, oral, or eye infection.

Transferred by direct sexual contact with infectious discharge.

Louis was 3rd and Chicago 14th in case frequency of gonorrhea in large cities

Spreads rapidly through sexually active population.

90% of women and 10% of men are asymptomatic.

Caused by small round bacteria often found in pairs, Neisseria gonorrhoeae.

Gonorrhea and Chlamydia (both caused by bacteria, often found in mixed infections).

Case frequency of congenital syphilis closely follows frequency in pregnant women-both have been declining since 1991.

25% of infected fetuses die before birth, 25% die after birth, 25% born with stage 2 syphilis, and 25% not infected.

Bacteria can cross placenta to infect fetus before birth.

100% preventable if mother diagnosed and treated before 16th week of pregnancy.

Treatment: penicillin (100% curable in stages 1 and 2, within 2-3 days not contagious, but must complete treatment).

More than 50% of women pass through stages 1 and 2 without knowing it.

After a peak in case frequency in 1991, incidence of syphilis has declined over 80% in US, and is now at the lowest frequency since 1941.

Black Americans are 30X more likely to have syphilis that white Americans.

Men (peak ages 35-39) are 50% more likely than women (peak ages 20-29) to have syphilis.

Blood test for antibacterial antibodies useful in diagnosis.

Not treatable, not contagious, damage not reversible.

Immune response made to bacteria causes damage to small blood vessels in various organs (brain, heart, kidney, liver, eyes, skin, bone).

Bacteria no longer detectable in tertiary syphilis.

25% develop serious tertiary stage symptoms.

50% of stage 2 never develop tertiary stage (or die of something else first).

Person may be asymptomatic for 3 to 30 years or more after secondary stage.

Blood test for anti-bacterial antibodies useful in diagnosis during secondary stage.

Rash goes away in 2-6 weeks regardless of treatment.

Secondary syphilis is contagious, but treatable.

Rash is systemic, may occur on thighs or trunk, with many lesions.

Skin rash typical of secondary syphilis.Person may be asymptomatic for 2-24 weeks before next stage.Bacteria transferred to another person by direct sexual contact (contact with fluid from lesion).

Can diagnose by using special microscopic technique to look at the bacteria (blood test not useful).Fluid from chancre is infectious (contains bacteria).Chancre may be internal or external, is painless, and goes away in 2-6 weeks without treatment.Three week incubation period between exposure and appearance of lesion (chancre).Picture of primary syphilitic lesions, or chancres, male (right) and female (left).Picture of spirochete bacteria that cause syphilis ( Treponema pallidum).Lecture Notes, Biology 203, Human Sexuality and Reproduction
