👉 Parainvenusta is a type of bacterial infection that can cause severe complications in the respiratory system, particularly when it involves the lungs and trachea. This condition typically begins with symptoms such as fever, coughing, shortness of breath, and chest pain or discomfort. In some cases, it may also include difficulty breathing due to the constriction of airway passages. The term "parainvenusta" is derived from Latin, meaning "bacteria that cause a disease."
