A. Diamant et al., X-CELL PSEUDOTUMORS IN A HARDHEAD CATFISH ARIUS-FELIS (ARIIDAE) FROM LAKE PONTCHARTRAIN, LOUISIANA, USA, Diseases of aquatic organisms, 18(3), 1994, pp. 181-185
X-cell epidermal lesions are described from a single specimen of the h
ardhead catfish Arius felis (Ariidae). The lesions exhibited an unusua
l growth pattern but did not involve any visceral organs. Histological
ly, the lesions resembled those previously described for coldwater fis
hes. This is the first report of X-cell lesions from Lake Pontchartrai
n, Louisiana, USA, and the hardhead catfish represents the first warmw
ater species affected with the disease.
