title: [Experimental data on the remanence of the virus causing the infectious pancreatic necrosis in Salmonidae in water environment (author's transl)].
abstract: To study the virus persistence in water environment, a purified suspension of the infectious pancreatic necrosis virus was submitted to different conditions of conservation: temperature of 4 degrees C and 1.4 degrees C in a mineral water of mean mineralization, temperature of 4 degrees C in a river water with a higher minerlization, filtered or not, with or without mud and vegetation. The cyto-infectious power of the virus subsists at least during 300 days at + 4 degrees C and 60 days at + 14 degrees C in the less mineralized water (fig I). Comparatively the virus strength sinks more slowly at 4 degrees C in the more mineralized river water (figure 2). When filtered this same river water keeps its infectious power better than its untreated homologous (fig. 3). The sediment and vegetation suspended in river water catch the virus (fig. 4 and 5).
