Chlamydia is an infection with Chlamydia bacteria. it is a sexually transmitted bacterium. When an infection is present, the bacteria can be present in the cervix, urethra, vagina, and rectum of an infected person, It can also live in the throat.
this bacteria lives inside cells, Infect columnar epithelial cells that can results in the death of the cells.
I will also be explaining about prevention, treatments and medicines (for women, men, pregnant women and kids )
2. • Chlamydia is an infection with Chlamydia
bacteria. When an infection is present, the
bacteria can be present in the cervix,
urethra, vagina, and rectum of an infected
person, It can also live in the throat.
• Lives inside cells
• Infect columnar epithelial cells
• results in the death of the cells

4. Species (genus) Disease
C. trachomatis conjunctivitis, Infant pneumonia,
C. pneumoniae Pharyngitis, bronchitis, pneumonia
C. psittaci Psittacosis (parrot fever)
5. • Transmission is sexual
• Incubation period 7-21 days
• Highly transmissible
• Significant asymptomatic reservoir exists in
the population
• Re-infection is common
• Any type of sexual contact (vaginal/vagina,
anal/ anus, or oral) with an infected person
can spread the infection.
• Chlamydia can also be passed during vaginal
birth to the infant, 30% - 50%
6. • Adolescence (old people)
• New or multiple sex partners
• Oral contraceptive user
7. • Majority (50%) asymptomatic
• Conjunctivitis
• Urethritis
• Prostatitis
• Symptoms/signs: mucoid or clear urethral
discharge, dysuria (pain during urination)
• Incubation period unknown (probably 5-10 days
in symptomatic infection)
11. Reduce its happening by more than 50%
Most infections are asymptomatic.
reduces the transmission of disease
Screening Recommendations: Non-pregnant Women
Sexually active women age 25 years and under
should be screened yearly.
Repeat screening of women 3-4 months after
treatment for C. trachomatis infection.
Screening recommendations: non-pregnant women:
Screen all pregnant women at the first prenatal visit.
Pregnant women aged more than 25 years and those
at increased risk for chlamydia should be screened
again in the third trimester.

orally divided into 4 doses daily for 14 days
- Children who weigh ≥45 kg, but are <8 years of age:
- Azithromycin 1 g orally in a single dose

16. 1. Culture:
- Historically the “gold standard”
- Variable sensitivity (50%-80%)
- High specificity
1. Nucleic Acid Amplification Tests (NAATs)
- more sensitive than other tests
1. Non-NAATs
- Enzyme imunoassay (EIA)
1. Rarely used for uncomplicated infections (results
difficult to interpret)
