Vibrio sp. INFL group that has been confirmed to be a causative bacterium of this discase by experimental infection(MASUMURA et al.,1989) was the dominant isolate from diseased flsh. In this study an indirect immunofluorescent technique and a histopathological study were performed to reveal the invasiveness of Vibrio sp. INFL group into intestinal tissues. Slight infectious lesions occurred in the mucosae of posterior part of intestine and the rectum. These lesions showed separation of affected mucosal cells with invasions of numbers of Vibrio sp. INFL group that were revealed by the specific fluorescence. Extended intestinal lesions involved the posterior half of intestine and the rectum. They showed marked bacterial multiplication in mucosae and the underlying tunica propria, and extensively slouphed mucosae, indicating that the histological characteristic was desquamative enteritis. The invasive bacteria were revealed to be Vibrio sp. INFL group by the specific fluorescence. Other visceral organs were spared of the bactorial invasions. The damage of intestine and rectum would induce fish mortalities.}, pages = {7--13}, title = {ヒラメ仔魚の腸管白濁症の病理組織学的研究}, volume = {25}, year = {1990} }
