Asahi Kasei Pharma Corp.

Asahi Kasei Pharma is launching the sale of Ribotest™ Legionella in Japan on February 1, 2019, as a new product in the Ribotest™ series of extracorporeal diagnostic kits. Ribotest™ Legionella assists the diagnosis of Legionnaires’ disease by enabling the detection of all 15 serogroups of Legionella pneumophila.

Developed with Asahi Kasei Pharma’s antibody technology utilizing the L7/L12 protein of the legionella bacterium, Ribotest™ Legionella enables the rapid diagnosis of infection by Legionella pneumophila, the most prevalent cause of Legionnaires’ disease. As this disease tends to progress quickly and lead to a severe condition, early diagnosis and prompt treatment are considered to be critical.

While the currently available rapid diagnostic test kits can only detect serogroup 1 of Legionella pneumophila, Ribotest™ Legionella can detect all 15 serogroups. The new kit is thus expected to make a significant contribution to the rapid diagnosis of Legionnaires’ disease. It will be sold by Alere Medical Co., Ltd. and Kyokuto Pharmaceutical Industrial Co., Ltd.
