Bacterial infection: mesenteric lymph node inflammation caused by bacterial infection can be treated with cefixime, cefdinir, etc. according to the drug sensitivity, mainly by inhibiting the synthesis of the bacterial cell wall, so as to achieve antibacterial effect. 2. Viral infections: viral infections resulting in inflammation of the mesenteric lymph nodes are self-limiting and can be treated symptomatically with compresses without special medication. 3. Tuberculosis infection: mesenteric lymph node inflammation caused by tuberculosis infection can be treated with isoniazid, rifampicin, etc. Due to the inhibition of phospholipids and branching bacilli within the cell wall, resulting in increased permeability of the cell wall, which leads to bacterial death due to the loss of acidity, so as to play the effect of anti-tuberculosis.
