Three weeks ago, she received a parrot as a birthday present. Her temperature is 38.5C 101.3F. Pulmonary examination shows crackles at both lung bases. Her leukocyte count is 8,000mm3. An x-ray of the chest shows diffuse patchy infiltrates that are most prominent in the lower lobes. Which of the following is the most likely causal organism?? A: Chlamydophila psittaci, B: Cryptococcus neoformans, C: Leptospira interrogans, D: Babesia microti, E: Francisella tularensis,  <response>: This is a medical diagnosis question involving a previously healthy 24-year-old woman who recently acquired a pet parrot and now presents with fever, headache, myalgia, photophobia, cough, and abnormal lung exam and chest x-ray findings. The key clues are the recent acquisition of a parrot, the pulmonary symptoms and infiltrates, and the normal leukocyte count. Chlamydophila psittaci choice A is the most likely diagnosis, as this organism can be transmitted from infected parrots and causes psittacosisornithosis, which commonly presents as an atypical pneumonia with systemic symptoms. Cryptococcus neoformans choice B is a fungus found in soil that can cause pneumonia, but there is no link to parrots and it more commonly causes meningitis in immunocompromised patients. Leptospira interrogans choice C causes leptospirosis, which may present with pulmonary involvement, but there is no association with parrots. The leukocyte count would likely be higher.Babesia microti choice D is a parasite transmitted by ticks that causes babesiosis. There is no link to parrots and it would not explain the pulmonary findings. Francisella tularensis choice E causes tularemia, but there is no association with parrots and it classically causes lymphadenopathy.A: Chlamydophila psittaci
