Aurantimonas coralicida

Aurantimonas coralicida is a gram-negative bacterium, and a causative agent of white plague in Caribbean corals. It is rod-shaped, with polar flagella.[1]


An obligate aerobe, A. coralicida obtains its nourishment chemoheterotrophically. It tests positive for oxidase and catalase, and contains carotenoid pigments, possibly to protect against solar radiation.[1]

Role in Disease[edit]

A. coralicida is believed to be the causative agent of white plague, a disease of some corals.[1] This was first described in 1995 in an epizootic in reefs in the Florida Keys. 17 of 43 coral species in the area were infected, and up to 38% of infected corals died.[1]


The type strain of A. coralicida is WP1T(=CIP 107386T =DSM 14790T), which was the original strain isolated.[1]


A coralicida was originally isolated as the cause of white plague in coral in the Caribbean in 1998.[1] In 2003, the 16s rRNA sequence of the bacterium was compared to other known sequences to determine its taxonomic relationship to other bacteria. It was found to be a previously-undescribed member of the order Rhizobiales and was classified under the newly created genus Aurantimonas as Aurantimonas coralicida.[1]
