Chlamydia is a common sexually transmitted bacterial infection caused by Chlamydia trachomatis. It is most prevalent in sexually active young men and women aged 15-25. The bacteria have a unique developmental cycle where they exist in both extra- and intracellular forms. While often asymptomatic, chlamydia infections can cause lymphogranuloma venereum, infant pneumonia, and urinary tract infections if left untreated. Diagnosis involves laboratory tests to detect signs of infection. Treatment consists of antibiotics like doxycycline or azithromycin. Abstaining from sex or using condoms can help prevent spreading chlamydia to partners.

2. Introduction
chlamydia is a common, sexually transmitted infection
caused by a bacteria, Chlamydia affects people of all ages
but is most common in young women. There are three
main species of Chlamydia causing human infection:
Chlamydia trachomatis, Chlamydia pneumoniae, and
Chlamydia psittacci.

3. Chlamydia organisms have a worldwide distribution.
C. trachomatis is now extremely common and the most
common sexually transmitted infection in Australia. In
particular, men and women between 15 and 25 years of
age are commonly affected
Distribution of chlamydia in humans
young men and women are mostly affected

4. Characteristics of bacteria
Chlamydiae are obligate, intracellular, nonmotile, gram-
negative bacteria with a unique biphasic developmental
cycle consisting of extra- and intracellular forms.
Chlamydiae have an outer membrane that contains
lipopolysaccharide (LPS) and membrane proteins.

6. Diagnosis
• Laboratory test may reveal general signs of chlamydia
infection – raised white cell count, elevated CRP (a non-
specific marker of inflammation).
• CXR may reveal an atypical pneumonia picture in C.
pneumoniae and C. psittacci.

7. Treatment of chlamydia
Antibiotics are used in the treatment of chlamydia
Regimes for uncomplicated infection include 100mg 12-
hourly doxycycline for 7 days, or 1g single dose oral
azithromycin, since it is asymptomatic It is important
that you tell anyone you have had sex with that you
have chlamydia infection, so they can be treated to
prevent nasty complications.
Thank you!

8. Prevention of chlamydia
Since chlamydia is sexually transmitted then one should apply the ABC
Rule in order to prevent this disease
• Abstain from sex
• Be faithful
• Use condoms
Persons with chlamydia Should abstain from sexual activity for 7 days
after single dose antibiotics or until complete of a 7 day course of
antibiotics, To prevent spreading the infection to partners.
