The following are the most important diseases or complications that may be contributed to by yersiniosis:
Skin and subcutaneous (L00-L99).
- Erythema nodosum (synonyms: nodular erysipelas, dermatitis contusiformis, erythema contusiforme; plural: erythemata nodosa) – granulomatous inflammation of the subcutis (subcutaneous fat), also known as panniculitis, and painful nodulation (red to blue-red color; later brownish). The overlying skin is reddened. Localization: both lower leg extensor sides, on the knee and ankle joints; less frequently on the arms or buttocks.
Cardiovascular system (I00-I99).
- Endocarditis (endocardial inflammation).
- Myocarditis (inflammation of the heart muscle)
Infectious and parasitic diseases (A00-B99).
- Sepsis (blood poisoning)
Musculoskeletal system and connective tissue (M00-M99).
- Osteomyelitis (bone marrow inflammation).
- Reactive arthritis (synonym: postinfectious arthritis/joint inflammation) – secondary disease after gastrointestinal (affecting the gastrointestinal tract), urogenital (affecting the urinary and genital organs) or pulmonary (affecting the lungs) infections; refers to arthritis in which pathogens (Campylobacter spp., Salmonella, Shigella, Yersinia) are (usually) not found in the joint (sterile synovitis).
Especially women older than 40 years can be affected by these sequelae.
