Chlamydiae and Zoonotic Intracellular Bacteria

Chlamydia species

• Three chlamydial species are pathogenic for humans: C. trachomatis, C. psittaci, and C. pneumoniae (Table 17-1).

Shared chlamydial properties

1. Chlamydiae are very small, obligate intracellular bacteria.

2. They possess a cytoplasmic membrane and outer membrane but lack peptidoglycan layer (unlike gram-negative bacteria) and thus are insensitive to β-lactam antibiotics.

3. Morphologic forms

4. Growth cycle (Fig. 17-1)

C. trachomatis

1. Identification

2. Pathogenesis

3. Chlamydial infections caused by types D through K (Box 17-1)

4. Lymphogranuloma venereum

• Caused by types L1 through L3 and transmitted by sexual contact

• Initial stage
