non-retroviral derived nucleic acid sequence. Examples of non-retroviral nucleic acid sequences are a neomycin resistance gene from the bacterial transposon TnS, a herpes simplex virus thymidine kinase gene and a chicken growth hormone gene, however, any prokaryotic or eukaryotic nucleic acid sequence of interest may be used. Transgenic chickens have been produced whose cells contain and express a replicationdefective retroviral vector nucleic acid sequence.
5165929 FUNGAL
ANT KILLER
William Howell The fungus, Rhizopus nigricans, can be used as an insecticide for use in killing ants in the order Hymenoptera. When this fungus is brought into or put into an ant hive, it kills the ants within a few days.
5165924 SERUM-FREE, CELL-FREE VACCINE EFFECTIVE AGAINST PNEUMONIC PASTEURELLOSIS IN CATTLE Patricia E Shewen, Bruce N Wilkie, Ontario, Canada assigned to University of Guelph A serum-free vaccine effective against pneumonic pasteurellosis in cattle comprising a nontoxic leukotoxin specific for ruminant leukocytes is disclosed. The leukotoxin is prepared in a serum-free medium from a culture of Pasteurella haemolytica. The produced leukotoxin is harvested from the culture medium upon detecting a certain stage during the logarithmic phase of the cell growth to obtain the optimum concentration of produced cytotoxin in the serum-free medium. Cattle may be treated with the vaccine to develop anti-leukotoxic immunity to pneumonic pasterellosis.
5165928 BIOLOGICAL CONTROL OF PHYTOPHTHORA BY GLIOCLADIUM Victoria Smith, Wayne F Wilcox, Gary E Harman assigned to Cornell Research Foundation Inc Certain strains of Trichoderma and Gliocladium protect plants against diseases caused by Phytophthora spp. when applied to root system biosphere, e.g., P. cactorum caused root rot and crown and collar rot in apple tree seedlings and P. sojae caused stem and root rot in soybeam plants.
5166196 METHOD FOR REMOVING IMMUNOCOMPLEXES FROM BLOOD Kazuy Otsuji, Hakar Inaoka, Yasuki Honda, Kikuhiko Okamoto, Morihisa Tanaka, Tsukas Matsumoto, Koji Ijima, Jong-Chol Cyong, Utsunomiya, Japan assigned to Kao Corporation A composition for curing autoimmune diseases is disclosed. The composition comprises as an effective component an acidic heteropolysaccharide which is secreted by a callus induced from a plant belonging to the genus Polianthes L. The acidic heteropolysaccharide can be prepared as a uniform product by the application of plant tissue culture methods and exhibits superior capability of removing immunocomplexes with the least side effects.
5169770 AGROBACTERIUM MEDIATED TRANSFORMATION OF GERMINATING PLANT SEEDS Paula Chee, Stephen Goldman, Anne C Graves, Jerry Slightom assigned to The University of Toledo PCT No. PCT/US88/04464 Sec. 371 Date Jun. 21, 1990 See. 102(e) Date Jun. 21, 1990 PCT Filed Dec. 16, 1988.A non-tissue culture process using Agrobacterium-mediated vectors to produce transgenic plants from seeds of such plants as the common bean and soybean.
