Study Notes
Chlamydia and Gonorrhoea
- Chlamydia is an intracellular bacteria, whereas Gonorrhoea is non-intracellular but becomes intracellular to avoid the immune system.
- Chlamydia cannot be grown on a plate, but can be cultured in cell culture, similar to a virus.
- Chlamydia has a typical Gram-negative cell wall with an inner membrane and outer membrane, but lacks peptidoglycan, which is important for the Gram stain reaction.
- Chlamydia infection is similar to Gonorrhoea, but lacks purulent material and instead presents with mucoid discharge.
- Symptoms of Chlamydia infection include little to no symptoms, but can cause mild inflammation in the cervix, conjunctions, and follicular symptoms (feeling like sand in the eye).
Treatment and Testing
- Azithromycin is the drug of choice for treating Chlamydia and Gonorrhoea infections.
- Penicillin binding proteins are lacking in Chlamydia, making beta-lactam antibiotics ineffective.
- Molecular testing is the preferred method for diagnosing Chlamydia, as it requires cells for growth.
- Testing can be performed on First void urine samples, but the choice of molecular target needs to be reviewed as mutant strains may result in negative molecular tests.
