Disease Identification

• Q fever, caused by Coxiella burnetii, has a mortality rate of 40% in untreated cases.
• Q fever is a rickettsial disease transmitted from animals to humans by inhalation.
• Psittacosis, caused by Chlamydia psittaci, can be contracted by inhaling respiratory droplets or dust from droppings of infected birds.
• Chlamydophila pneumoniae causes a disease characterized by lower respiratory infection, fever, non-productive cough, and can lead to pneumonia and CNS involvement.
• Trachoma, caused by Chlamydia trachomatis, can lead to blindness if not treated.
• Chlamydial keratoconjunctivitis can scar the cornea in 15-20 years if not treated.
• Chlamydia trachomatis is the single most frequent bacterial STD in the U.S., causing over 4 million cases per year.
• Chlamydia trachomatis can cause urethritis, endometritis, and PID in females, and nongonococcal urethritis, epididymitis, and prostatitis in males.
• Chlamydial conjunctivitis is characterized by acute, copious, purulent eye discharge and is often found in populations where genital infections are common.
• Lymphogranuloma venereum, caused by Chlamydia trachomatis, is characterized by inguinal swelling and lymphatic drainage and is commonly found among immigrants and travelers.
