Fecal material from cattle, which was confirmed to be infected with Johne's disease by clinical and pathological symptoms, was decontaminated with 4% NaOH and inoculated into the Lowenstein-Jensen media supplemented with 1% of heat-killed Mycobacterium bovis. After 2-4 week-incubation at 37 deg C, typical acid-fast mycobacteria was isolated. The requirements of mycobactin for growth and the other biochemical properties, isolated mycobacteria was identified as Mycobacterium paratuberculosis

1986
Shin, T.K. | Kim, M.G. (Chungnam National Univ., Taejon (Korea R.). Coll. of Medicine)
Authors evaluated retinal toxicity produced by intraocular injection of kainic acid in 10 ducks to provide further informations on the kainic acid induced retinal lesions in the avian species. By 8 hrs after injection there were severe vacuolar degenerations in the inner plexiform layer and the inner portion of the inner nuclear layer; by 24 hrs after injection many of the cells exhibited pyknotic nuclei in the inner nuclear layer; by 48 hrs after injection the reduction in the thickness was apparent in this layer because of the partial loss of the pyknotic cells. By 96 hrs there were only a few cells in the center and inner protion of the inner nuclear layer; by 10 days there was a conspicuous decrease in the thickness of the inner nuclear layer and the inner plexiform layer
