  Mesenteric adenitis is a syndrome characterized by right lower quadrant pain secondary to an inflammatory condition of mesenteric lymph nodes. […] The etiologies of mesenteric adenitis include several causes of inflammatory response within mesenteric lymph nodes. These include viral infections, bacterial infections, inflammatory bowel disease, or lymphoma. Two common gram-negative bacteria that are known to cause mesenteric adenitis include Yersinia pseudotuberculosis and Yersinia enterocolitica. […] Other known culprits include salmonella, E coli, and streptococci. The etiology can further classify as primary versus secondary. Primary etiology occurs when the lymphadenopathy is the result of an unidentifiable inflammatory process. Secondary mesenteric adenitis occurs secondary to an intra-abdominal inflammatory process with a known source or etiology.

  Mesenteric lymphadenitis is the inflammation of the lymph nodes on the wall of the mesentery (the covering of the intestines) in the absence of appendicitis, leading to abdominal pain. […] The following are the usual causes of mesenteric lymphadenitis: […] Several studies have shown that up to 60 percent of mesenteric lymphadenitis are caused by viruses. […] Bacteria contamination of food can mesenteric lymphadenitis. […] Parasitic protozoa has also been shown to cause mesenteric adenitis. […] Any of these infections – virus, bacteria or parasite can get into our intestine and get trapped inside the lymph nodes on the mesentery and trigger an inflammation, leading to the enlargement of the lymph nodes and the symptoms of mesenteric lymphadenitis.

  Numerous organisms have been cultured from mesenteric lymph nodes and blood, such as beta-hemolytic streptococcus, Staphylococcus species, Escherichia coli, Streptococcus viridans, Yersinia species (responsible for most cases currently), Mycobacterium tuberculosis, Giardia lamblia, and nonSalmonella typhoid. Viruses, such as coxsackieviruses (A and B), rubeola virus, and adenovirus serotypes 1, 2, 3, 5, and 7, have also been implicated. […] Mesenteric node involvement can also be part of infectious Epstein-Barr virus (EBV), acute human immunodeficiency virus (HIV) infection, and catscratch disease (CSD). […] The frequent association of this condition, especially in children with upper respiratory tract infection, has popularized a theory that swallowed pathogen-laden sputum may be the primary source of infection. […] Fecal-oral transmission occurs in Y enterocolitica infection and may present as a common source outbreak. This infection has also been associated with meat, milk, and water contamination. Rarely, person-to-person or zoonotic contacts with fecal carriers can lead to infection.

  https://www.afcurgentcare.com/sevierville-tn/blog/what-are-the-common-risk-factors-of-mesenteric-adenitis/

  Mesenteric adenitis (also known as mesenteric lymphadenitis) is the swelling of the lymph nodes in the mesentery, which attaches the intestines to the abdominal wall. […] Mesenteric adenitis is most often caused by a viral or bacterial intestinal infection, which causes the lymph nodes to swell, thus inducing pain and tenderness. […] Because mesenteric adenitis is almost always caused by a bacterial or viral infection, it is unlikely to appear out of nowhere. Lymphadenitis is almost always the result of a previous infection, such as a stomach virus, a cold virus or a respiratory infection. Y. enterocolitica-infected pork can also cause lymphadenitis.

  Mesenteric lymphadenitis is a condition characterized by inflammation of the lymph nodes in the mesentery. Systemic inflammatory response syndrome (SIRS) is a clinical response to a non-specific insult, which can be caused by various factors such as infection, trauma, burns, or other severe bodily stresses. […] Mesenteric lymphadenitis is usually caused by bacterial or viral infections and is more common in children and young adults. […] While it is important to consider the potential relationship between mesenteric lymphadenitis and SIRS, it is also crucial to acknowledge that not all cases of mesenteric lymphadenitis lead to SIRS. […] The inflammatory response in mesenteric lymphadenitis tends to be contained within the abdominal area and may not always meet the criteria for a systemic inflammatory response. […] Although mesenteric lymphadenitis and SIRS are primarily distinct conditions, their intersection in clinical scenarios underscores the importance of vigilant assessment and management to prevent potentially life-threatening complications.
