Geographic distribution Ubiquitous.
Host species All penaeids.
Similar bacteria have been observed on Pandalus platyceros held in captivity. Impact on the host Discolouration of gills due to associated secondary infections. Larvae and postlarvae fouled. Reduced mobility, feeding and growth. Direct microscopic examination of body surface at 100 or higher reveals filaments of bacteria 3-5 m wide and of variable length but often 100 to 500 m long.
