Legionella Support Services

Legionella is a pathogenic group of bacteria that can cause illness. Legionellosis refers to two distinct clinical syndromes: Legionnaires disease which most often manifests as severe pneumonia accompanied by multi-systemic disease, and Pontiac fever which is an acute, febrile, self-limited, viral-like illness. Legionella is considered to be fairly common and serious; the Legionella organism is one of the top three causes of sporadic, community-acquired pneumonia.

VERTEX provides significant benefits for your business with respect to identifying and/or managing potential bacteria associated with Legionella.
