T
he combination of physical stress and disease has resulted in
the decline of corals and coral reefs throughout the Caribbean
(1,2). In the Florida Keys and elsewhere, the iconic elkhorn coral
(Acroporapalmata) has experienced precipitous declines due in
part to white pox disease (WPD) (3, 4). Following outbreaks of
WPDin the late 1990s and early 2000s, the bacterium Serratia
marcescenswas isolated from diseased corals and subsequently
identified as an etiological agent by fulfillment of Koch’s postulates (4, 5). As originally proposed (4), to distinguish the disease
causedby this bacterium from broader signs of WPD, it is referred
to as acroporid serratiosis when, and only when,S. marcescensis
confirmed from a lesion on anA. palmatacolony.
