Gonorrhoea
Presented by:- Meenakshi Tadhiyal
Roll No.:- 24
Batch:- 2018
What is
gonorrhoea??
 A sexually transmitted disease caused by
gonococcal bacteria that affects the
mucous membrane chiefly of the genital
and urinary tracts and is characterized by
an acute purulent discharge and painful
or difficult urination, though women
often have no symptoms.
Neisseria gonorrhoeae
Neisseria gonorrhoeae
 a gram-negative (coffee bean shaped) diplococcus
shifting from 0.6 to 1.0 micrometer in diameter.
 It has 2069 genes, 2002 protein genes, and 67
structural RNAs.
 They grow on chocolate agar with Carbon
Dioxide.
 It multiplies in warm and moist areas because it's
easy to grow. Ex: reproductive tract, urine canal,
History: when & who
discovered It?
 Neisseria Gonorroeae
was discovered in
1879.
 By (and named after)
a a German physician
and bacteriologist,
Albert Ludwig
Sigesmund Neisser.
Modes of transmission
 Unprotected sex
 Oral sex
 When someone is infected, the bacteria can
be easily spread by: rubbing your eyes.
 Mothers who are infected can give their baby
the infection through delivery.
Pathogenesis
 Only mucous membranes lined by
columnar or cuboidal, noncornified
epithelial cells are susceptible to
gonococcal infection.
 N. gonorrhoeae adhere to mucosal cells ,
mediated by pili, Opa, and other surface
proteins.
Steps of pathogenesis
Invasion :-Organism is then pinocytosed by epithelial
cells, which transport gonococci from mucosal
surface to subepithelial spaces.
Adherence :- initial event , N. gonorrhoeae adhere
to mucosal cells , mediated by pili, Opa, and other
surface proteins.
Invasion :-Organism is then pinocytosed by
epithelial cells, which transport gonococci from
mucosal surface to subepithelial spaces.
 Simultaneous with attachment of
gonococci to nonciliated epithelial cells,
gonococcal LOS(endotoxin) impairs
ciliary motility and contributes to
destruction of surrounding ciliary cells.
 3. Tissue damage :-Progressive mucosal
cell damage and submucosal invasion are
accompanied by a vigorous neutrophil
response, submucosal microabscess
formation, and exudation of purulent
material into lumen of the infected organ.
This process may promote further attachment
of additional organisms.
 Dissemination:- ability to resist the
killing activity of antibodies and
complement in normal human serum is
closely related to the ability of gonococci
to cause bacteremic illness with or
without septic arthritis.
Pathogenesis
Symptoms in
men
Symptoms begin: 2 to 14
days
 Burning sensation while
urinating.
Testicular swelling and/or
pale Green, yellow
discharge.
Symptoms in women
 Symptoms begin: 7 to 21 days
Pain and burning sensation
while urinating.
 Spotting blood after sex.
 Irregular bleeding period.
 Yellow, green, and white
discharge.
Common Symptoms
Rectal infection
 Rectal mucosa is infected in 35–50% of
women with gonococcal cervicitis.
 Only rectum is involved in 5% women.
 40% in homosexual men.
 Symptoms range from minimal anal
pruritus, painless mucopurulent
discharge (often manifested only by a
coating of stools with exudate),
 or scant rectal bleeding, to symptoms of overt
proctitis, including severe rectal pain,
tenesmus, and constipation.
 External inspection :- only occasionally shows
erythema and abnormal discharge .
 On Anoscopy:- mucoid or purulent exudate (
localized to anal crypts), erythema, edema,
friability, or other inflammatory mucosal
Pharyngeal Infection
 3–7% of heterosexual men.
 10–20% of heterosexual
women.
 and 10–25% of homosexually
active men.
 acute pharyngitis or tonsillitis
and occasionally is associated
with fever or cervical
lymphadenopathy.
 >90% are asymptomatic
Disseminated gonorrhoea With
layngeal involvement
Who are at risk?
 Any sexually active person Ages between
15-29 years old have the highest rates of
gonorrhea.
 In 1996, gonorrhea rates were high for
men. 2010, women's rates are higher.
Laboratory diagnosis
 Gram’s stain:- Microscopic examination of
stained smears shows gram –ve diplococci in
PMN are seen.
 Culture:- antibiotic-containing selective media
(e.g., modified Thayer- Martin medium) have
diagnostic sensitivities of 80– 95% for promptly
incubated specimens, depending in part on
anatomic site being cultured.
 Small pinpoint colonies can be seen.
Gram
Stain
Culture
 Oxidase reaction:- aids to identify gonococci from
mixed culture .
 A drop of tetra methyl-p-phenylene diamine
hydrochloride is poured over suspected colonies,
which turn pink and then dark blue.
Oxidase reaction
Non diagnostic
techniques
Nucleic acid amplification tests
(NAATs):- polymerase chain reaction
(PCR), transcription-mediated
amplification (TMA), and other nucleic
acid amplification technologies. More
sensitive than culture for gonorrhea
diagnosis and specificities are nearly as
Complications
 Pelvic inflammatory disease (PID)
 Infertility
 Scarring or narrowing of the urethra
 Abscess (collection of pus around the
urethra)
 Joint infections
 Heart valve infection
 Meningitis
 Pregnant women with severe gonorrhea may
pass the disease to their baby while in the
womb or during delivery.
 Premature delivery
 Spontaneous abortion
 Blindness, joint infection, or blood infection
Treatment
 While under treatment, one must not
have any sexual contact. – Must wait at
least 7 days after medication. – Both
partners must be tested & treated or else
the infection will happen again. If failed,
one must be tested for a gonorrhea
culture (sample of body fluid),
Prophylaxis of Opthamia
neonatorum
 Prevention is for all of preterm infants.
It is done immediately after birth. Silver
nitrate, 1% aqueous solution of a single
dose of 2-3 drops in each eye.
Erythromycin 0.5%, 1% eye ointment
once Tetracycline 1% eye ointment
Neonatal conjutivitis
Treatment of gonococcal
infection in childrens
 Ceftriaxone (Rocephin) / m single 125
mg (body weight less than 45kg)
Alternative modes: Spektomitsetin 40
mg / kg dose. And children weighing
over 45 kg, are treated like an adult.
Treatment of uncomplicated gonococcal
infection of urethra, cervix & rectum
 Single dose of Tab.
cefixime 400mg, Inj.
Ceftriaxone 125 mg IM,
tab. Ciprofloxacin
500mg, tab. Ofloxacin
400mg, or tab.
Levofloxacin 250mg
PLUS
If chlamydial infection
is not ruled out- tab.
Azithromycin 1 g
single dose or tab.
Doxycyclin 100mg BID
x 7days.
“Fun fact”
 In France, gonorrhea was known as “La
chaude pisse” (Hot piss) because of the
burning sensation while urinating.
 It's also called as“The Clap!”Nickname
from a treatment: clapped on both side
of the penis for the discharge to come
out.
Thankyou
