OBJECTIVES
Upon completion of this course the participant will
be able to:
1. Discuss the principal characteristics of chlamydiae, including their intracellular
life cycle and their classification.
2. Contrast the classic chlamydiae species with the newly described Para- chlamydiaceae.
3. Outline the pathogenesis of chlamydial infections.
4. Discuss human diseases caused by chlamydiae, including emerging chlamydial
infections.
5. Describe the possible role of chlamydia in chronic diseases.
6. Summarize current diagnostic methods and treatment options.
INTRODUCTION
Long considered a unique group of intracellular bacteria containing
a few pathogenic species, the chlamydiae have recently been shown through molecular
studies to represent a highly diverse group of ubiquitous organisms. In addition
to well known human pathogens there is an abundance of environmental chlamydiae
symbiotic in free-living amoebae and in other hosts. These symbionts are obligate
intracellular parasites. Phenotypic comparison of newly described chlamydial
groups suggests that all have descended from a common ancestor that replicated
intracellularly within eukaryotic host cells. The minor phenotypic differences
observed among chlamydial groups depend on small genomic differences.
The divergence of environmental and pathogenic chlamydiae is thought
to have taken place about 700 million years ago. The common ancestor of diverse
chlamydial groups was already adapted to intracellular survival in early eukaryotic
cells and contained many virulence factors found in modern pathogenic chlamydiae.
Recent molecular studies of environmental chlamydiae have identified three families:
Simkaniaceae, Parachlamydiaceae, and Waddliaceae.
