Chlamydia bacteria

Chlamydia trachomatis

Three varieties of chlamydia bacteria infect humans. Chlamydia pneumoniae, Chlamydia psittaci, and Chlamydia trachomatis. They cause respiratory illness, such as pneumonia and bronchitis, being passed to others via coughing and sneezing; or passed to humans from birds, causing an infection called psittacosis; and the most common sexually transmitted infection - Chlamydia. This bacterial strain is also passed to children during birth if their mother is infected and can be passed via any intimate contact, including in the throat.
