Coral
Disease Identification and Information
Disease
Overview White
pox is characterized by coral tissue degradation that occurs in
association with circular lesions on the Caribbean
scleractinian coral Acropora
palmata. Rapid loss
of tissue progresses along a distinct line, or with small remnants
of tissue sometimes present near the margin of, irregularly shaped
patches anywhere on the upper or lower surfaces of Acropora
palmata branches. The
average rate of tissue loss is 2.5 cm2/day, although
rates up to 10.5 cm2/day can occur. It
is caused by the bacterium Serratia
marcescens, a well-known species that is widespread in both
terrestrial and aquatic environments as well as in mammalian and
arthropod hosts (Patterson et al., 2002).
White Pox (synonym: acroporid serratiosis) White pox is characterized by circular lesions. The pathogen is Serratia marcescens, a gram negative member of the enterobacteria. *** Click images to view full sized high resolution image ***
