1. Gonorrhea is caused by the bacterium Neisseria gonorrhoeae and can infect the genitals, rectum, and throat through sexual contact. It is the second most commonly reported infectious disease in the US with over 700,000 new cases per year. 2. Symptoms of gonorrhea vary between men and women. Men typically experience painful urination while infections in women are often asymptomatic, leading to untreated pelvic inflammatory disease and infertility. 3. Diagnosis involves gram staining, culture, or detection of bacterial components. Treatment consists of a single dose of ceftriaxone or cefixime plus azithromycin.

3.  Gono-seeds, rhoea-flow.
so, gonorrhoea means abnormal flow of semen.
 Caused by gram-negative diplococcus Neisseria
gonorrhoeae.
 Gonorrhea can cause infections in the genitals, rectum,
and throat.
 Vaginal, anal, or oral sex with someone who has
gonorrhea.
 Humans are the only known host of this intracellular
parasite.

4. In the U.S.
 2nd most common disease that is required to be
reported.
 718,000 new cases per year.
 Adolescent women (ages 15 to 19) currently have the
highest rates of infection.
 High risk of single episode of vaginal intercourse with
an infected male & increases with multiple exposures
(50%-70%).
 Risk of transmission from infected female to an
uninfected male is not as great following a single
episode(20%).

5.  Multiple & new sex partners
 Inconsistent condom use
 Urban residence
 Adolescents, females particularly
 Lower socio-economic status
 Drug addicts
 Exchanging of sex for drugs & money

6.  Efficiently transmitted by sexual contact
-Male to female via semen
-Female to male urethra
-Anal intercourse
-Oro-genital sex (pharyngeal infection)
-Peri-natal transmission (mother to infant)
 Gonorrhea associated with increased transmission &
susceptibility to HIV infection

7.  On contact with a mucosal surface lined by columnar,
cuboidal, or noncornified squamous epithelial cells, the
gonococci attach to cell membranes by means of surface
pili and are then pinocytosed.
 The virulence of the organism is mediated primarily by
the presence of pili and other outer membrane proteins.
After mucosal damage is established, polymorphonuclear
(PMN) leukocytes invade the tissue, submucosal
abscesses form, and purulent exudates are secreted.
 Most common sites of inoculation:
• Cervix (cervicitis) or vagina in the female
• Urethra (urethritis) or penis in the male

8. Differences Between Men
& Women with Gonorrhea

9. IN MEN:
 Urethritis; Epididymits
 Most infections among men are acute and symptomatic
with purulent discharge & dysuria (painful urination) after
2-5 day incubation period
 Male host seeks treatment early preventing serious
sequelae, but not soon enough to prevent transmission to
other sex partners
 The two bacterial agents primarily responsible for
urethritis among men are N. gonorrhoeae and Chlamydia
trachomatis

10. IN WOMEN:
 Cervicitis; Vaginitis; Pelvic Inflammatory
Disease (PID); Disseminated Gonococcal
Infection (DGI)
 Women often asymptomatic or have atypical
indications (subtle, unrecognized S/S); Often
untreated until PID complications develop
 Pelvic Inflammatory Disease (PID)
• May also be asymptomatic, but difficult diagnosis
accounts for many false negatives
• Can cause scarring of fallopian tubes leading to
infertility or ectopic pregnancy

11. IN WOMEN:
 Disseminated Gonococcal Infection (DGI):
• Result of gonococcal bacteremia
• Often skin lesions
• Petechiae (small, purplish, hemorrhagic spots)
• Pustules on extremities
• Arthralgias (pain in joints)
• Tenosynovitis (inflammation of tendon sheath)
• Septic arthritis
• Occasional complications: Hepatitis; Rarely
endocarditis or meningitis

associated complications (ie,
ectopic pregnancy, infertility)
Disseminated gonorrhea (3 times
more common than in men)

13.  Gram-stained smears, culture, or methods based
on the detection of cellular components of the
gonococcus
 Alternative methods of diagnosis, including
1. Enzyme immunoassay (EIA),
2. DNA probe techniques, and
3. Nucleic acid amplification techniques (NAATs)

14.  NOTE: Importance of
Sensitivity vs. Specificity
for any Diagnostic Test

15. Sensitivity = Measure of True Positive Rate (TPR)
TPR = No. of True Pos. = No. of True Positive .
No. of Actual Pos. No. of (True Pos. + False Neg.)
Specificity = Measure of True Negative Rate (TNR)
TNR = No. of True Neg. = No. of True Neg. .
No. of Actual Neg. No. of (True Neg. + False Pos.)

16.  All gonorrhoea treatment regimens recommended
by the Centers for Disease Control and Prevention
(CDC) consist of various oral or parenteral
cephalosporins and fluoroquinolones given as a
single dose.
 Ceftriaxone, the only parenteral agent included in
CDC recommended first-line agents for the
treatment of gonorrhoea, is administered IM as a
single 125 mg dose.
 Some clinicians advocate that a single 2g dose of
azithromycin should be treatment of choice for
gonorrhoea because it is also effective in
eradicating concomitant chlamydial infection.

19. Treponema pallidum

20.  The causative organism of syphilis is Treponema pallidum,
a spirochete.
 Syphilis usually is acquired by sexual contact with infected
mucous membranes or cutaneous lesions, although on
rare occasions it can be acquired by nonsexual personal
contact, accidental inoculation, or blood transfusion.
 Syphilis has been known as "the great imitator" as it may
cause symptoms similar to many other diseases.

21.  In 2015, about 45.4 million people were infected with
syphilis, with 6 million new cases. During 2015, it caused
about 107,000 deaths, down from 202,000 in 1990.
 Of these newly diagnosed cases, 91% were reported in
men, the majority of whom were reported as MSM.

22.  The signs and symptoms of syphilis vary depending in
which of the four stages:
1. Primary syphilis,
2. Secondary syphilis,
3. Latent syphilis, and
4. Tertiary syphilis.

23.  The primary stage classically presents with a single
chancre (a firm, painless, non-itchy skin ulceration) but there
may be multiple sores.
 Typically disappear after a few weeks without treatment (still
progresses to next stage)
 Acquired by direct sexual contact with the infectious lesions of
another person.
 Incubation period- 9-90 days (mean, 21 days)
 Sharp borders- 0.3–3.0 cm in size
 The most common location in women is the cervix (44%),
the penis in heterosexual men (99%), and anally
and rectally relatively commonly in men who have sex
with men (34%).

24. Primary syphilis - chancre

25.  Develops 2-8 weeks after initial infection in untreated or
inadequately treated Individuals.
 In secondary syphilis a diffuse rash occurs, which frequently
involves the palms of the hands and soles of the feet.
 There may also be sores in the mouth or vagina.
 There may be a symmetrical, reddish-pink, non-itchy rash on
the trunk and extremities, including the palms and soles.
 Other symptoms may include fever, sore throat , malaise
, weight loss, hair loss, and headache.
 Rare manifestations include liver inflammation
, kidney disease, joint inflammation, periostitis , inflammation
of the optic nerve, uveitis, and interstitial keratitis.

26. SECONDARY SYPHILIS

27.  Latent syphilis is defined as having serologic proof of
infection without symptoms of disease.
 In latent syphilis, which can last for years, there are few
or no symptoms.
 It is further described as-
1. Early (less than 1 year after secondary syphilis)
2. Late (more than 1 year after secondary syphilis)
 Early latent syphilis may have a relapse of symptoms.
Late latent syphilis is asymptomatic, and not as
contagious as early latent syphilis.

28. Late syphilis

29.  In tertiary syphilis there are gummas (soft non-cancerous
growths), neurological, or heart symptoms.
 Tertiary syphilis may occur approximately 3 to 15 years after
the initial infection
 It may be divided into three different forms:
1. Gummatous syphilis (15%)
2. Late neurosyphilis (6.5%), and
3. Cardiovascular syphilis (10%)
 Gummatous syphilis or late benign syphilis usually occurs 1-
46 years after the initial infection, with an average of 15 years.
 Typically affect the skin, bone, and liver, but can occur
anywhere.

30. Cardiovascular syphilis -
narrowing of coronary ostia
in aortus
Neurosyphilis - spirochetes in
neural tissue

31.  In pregnant women with syphilis, T. pallidum can cross
the placenta at any time during pregnancy.
 Transmission of syphilis during pregnancy occurs
primarily transplacentally and can result in fetal death,
prematurity, or congenital syphilis.
 Symptoms can be seen during the first months of life
(early congenital syphilis) or later in childhood or
adolescence (late congenital syphilis)

32. Clinical presentation of Syphilis
General
Primary Incubation period 10-90 days (mean, 21 days)
Secondary Develops 2-8 weeks after initial infection in untreated or
inadequately treated Individuals
Latent Develops 4-10 weeks after secondary stage in untreated or
inadequately treated individuals
Tertiary Develops in approximately 30% of untreated or inadequately
treated individuals 10-30 years after initial infection
Site of Infection
Primary External genitalia, perianal region, mouth, and throat
Secondary Multisystem involvement secondary to hematogenous and
lymphatic spread
Latent Potentially multisystem involvement (dormant)
Tertiary CNS, heart, eyes, bones, and joints

33. Signs and Symptoms
Primary Single, painless, indurated lesion (chancre) that
erodes, ulcerates, and eventually heals (typical);
regional lymphadenopathy is common; multiple,
painful, purulent lesions possible but uncommon
Secondary Pruritic or nonpruritic rash, mucocutaneous lesions,
flu like symptoms, lymphadenopathy
Latent Asymptomatic
Tertiary Cardiovascular syphilis (aortitis or aortic
insufficiency), neurosyphilis (meningitis, general
paresis, dementia, tabes dorsalis, eighth cranial
nerve deafness, blindness), gummatous lesions
involving any organ or tissue

34.  Serologic test
 Dark-field microscopic examination
 Direct fluorescent-antibody (test) for T. pallidum (DFA-TP),
 Common nontreponemal tests include:
1. Venereal Disease Research Laboratory (VDRL) slide test,
2. Rapid plasma reagin (RPR) card test,
3. Unheated serum reagin (USR) test, and
4. Toluidine red unheated serum test (TRUST).
