Chlamydia Bacteria Developmental Cycle
The developmental cycle of chlamydia is explained below:
Attachment and Entry
- Chlamydia attaches to the host cell membrane, often epithelial cells of mucous membranes, using adhesion molecules.
- It enters the host cell through endocytosis, forming a membrane-bound vesicle called an inclusion.
Differentiation into Elementary Bodies (EBs)
- Within the inclusion, Chlamydia differentiates into elementary bodies (EBs), which are small, metabolically inactive, and highly infectious.
- This transformation is essential for survival and transmission.
Multiplication as Reticulate Bodies (RBs)
- The EBs then transform into reticulate bodies (RBs), which are larger, metabolically active, and non-infectious.
- RBs replicate within the inclusion by binary fission, utilizing host cell resources.
- After several rounds of replication, RBs re-differentiate back into infectious EBs.
Release and Spread
- The host cell lyses, releasing newly formed EBs, which can infect neighboring cells.
- Alternatively, EBs are released via exocytosis without host cell lysis, allowing for stealthy spread within tissues.
- The host immune system recognizes the infection and provides an immune response, including both innate and adaptive immune mechanisms.
Chronic Infection or Clearance
- In some cases, Chlamydia can establish chronic infections, persisting within host cells and evading immune clearance.
- However, in many cases, the immune response clears the infection, leading to resolution of symptoms.
Chlamydia Overview
Chlamydia is one of the sexually transmitted infection (STI) which is caused by the bacterium chlamydia trachomatis. Chlamydia infection spreads through unprotected sexual contact. Often there are no chlamydia symptoms which allows it to proliferate undetected. If left untreated, chlamydia can cause severe complications such as pelvic inflammatory disease and infertility.
Timely diagnosis and chlamydia treatment with antibiotics are essential to prevent the spread of the infection and long-term health consequences. In this article, we will study chlamydia and its biological classification, symptoms, diagnosis, and treatment in detail.
