 Helicobacter spp. hat exhibit a large helical form, collectively referred to as HHLO(Helicobacter heilmannii-like organism), are a cause of zoonotic infections, and a mild gastric mucosal disorder is often observed. However, in recent years, this organism has attracted attention because of its suggested association with nodular gastritis and gastric MALT(mucosa-associated lymphoid tissue)lymphoma. The infection rate of our cases in Japan is 0.1%, which is approximately the same as in other developed countries. Eradication therapy was performed in six patients with HHLO-associated gastric MALT lymphoma, including one who underwent additional radiation therapy, and all six cases have maintained remission.

 The probability of encountering a case of HHLO infection in everyday clinical practice is low compared with that of Helicobacter pylori infections. However, it may be noteworthy with respect to the development of MALT lymphoma.Thus, the establishment of culture methods as well as analysis and classification using molecular biology techniques are expected.
