FUSARIUM-SOLANI FUNGAL INFECTION OF THE LATERAL-LINE CANAL SYSTEM IN CAPTIVE SCALLOPED HAMMERHEAD SHARKS (SPHYMA-LEWINI) IN HAWAII

Two of five scalloped hammerhead sharks (Sphyrna lewini) captured May 1987 in Hawaii (USA) developed granulomatous exudative mycotic dermati tis localized in the lateral line canal system, The lesion initially w as noted in the cephalic canals, but over a period of months extended into the lateral canal. Fusarium solani and Vibrio spp. were isolated from the canal exudate of both sharks. Bacterial colonies were not obs erved in the canal walls or surrounding tissues. Fusarium solani infec tion resulted in a chronic physical and behavioral deterioration of th e two sharks; one shark was euthanized in September 1988 and the other in July 1989. This is the first report of Fusarium solani infection i n the lateral line canal system and the third account in hammerhead sh arks.
