Summary Introduction
Introduction:
A patient’s serum, Chlamydia, guinea pig complement, sheep red blood cells and anti-sheep red blood cells are mixed in a tube. No hemolysis occurs, when the patient has antibodies against the Chlamydia. This gives the ocular infections in guinea pig.

Thank you An 87-year-old woman with dementia lives in a nursing facility. A nurse notices that she has been coughing frequently and seems warm to the touch. She performs an evaluation on the woman and confirms a fever with a dry cough. She also notices that her throat seems inflamed and irritated. The woman is unable to answer questions about how she has been feeling lately to provide a history for the nurse. The nurse ensures that the woman is comfortable and returns to the nursing station to review that patient’s chart. The nurse finds that within the year that the patient has been in the nursing facility, she has had two respiratory infections diagnosed as pneumonia. The nurse calls the physician, worried that the patient may be developing pneumonia again. 1). Pneumonia is an infection of the lung that can be caused by a virus, bacteria, or fungi.
