👉 Paratephritis is a condition characterized by inflammation of the small intestine, often leading to severe abdominal pain and fever. It is caused by an infection with Streptococcus pyogenes or Escherichia coli, which can be spread through contaminated food or water sources. Symptoms may include cramping, diarrhea, nausea, vomiting, fever, and sometimes abdominal pain. Treatment typically involves antibiotics, usually given intravenously to the abdomen for at least 14 days.
