Pleuropneumonia is an infection that affects the lungs and the pleura, the membrane surrounding the lungs. It is often caused by bacteria, viruses, or fungi, leading to inflammation and fluid accumulation in the pleural space. Symptoms may include cough, fever, chest pain, and difficulty breathing. This condition can occur in both humans and animals, particularly in livestock such as cattle and pigs. Treatment typically involves antibiotics to combat the infection and supportive care to manage symptoms. Early diagnosis and intervention are crucial for a better prognosis and recovery.
