Legionnaires' disease Although the risk of Legionnaires' disease being spread by large-scale water systems cannot be eliminated, it can be greatly reduced by writing and enforcing a highly detailed, systematic water safety plan appropriate for the specific facility involved (office building, hospital, hotel, spa, cruise ship, etc.) Some of the elements that such a plan may include are: An effective water safety plan also covers such matters as training, record-keeping, communication among staff, contingency plans, and management responsibilities.

Bacterial cold water disease eggs. Bacterial cold water disease Bacterial cold water disease (BCWD) is a bacterial disease of salmonid fish. It is caused by "Flavobacterium psychrophilum" (previously classified in the genus "Cytophaga"), a gram-negative rod-shaped bacterium of the family Flavobacteriaceae.

This disease is not zoonotic. Asymptomatic carrier fish and contaminated water provide reservoirs for disease. Transmission is mainly horizontal, but vertical transmission can also occur. BCWD may be referred to by a number of
