386 PATENT ABSTRACTS 5418152 ACIDIC POLYCYCLIC ETHER ANTIBIOTIC Cullen Walter; Dirlam John P; Maeda Hiroshi; Tone Junsuke East Lyme, CT, UNITED STATES Assigned to Pfizer Inc PCT No. PCT/US91/06084 Sec. 371 Date Mar. 12, 1993 Sec. 102(e) Date Mar. 12, 1993 PCT Filed Aug. 30, 1991. An acidic polycyclic ether antibiotic, having structure established by X-ray crystallography, is formed by fermentation of a novel microorganism, Actinomadura sp. ATCC 55080. This novel antibiotic is useful as an anticoccidial in poultry, in the prevention and treatment of swine dysentery and as a growth promotant in cattle and swine. 5418159 LEUKAEMIA INHIBITORY FACTOR FROM LIVESTOCK SPECIES AND USE THEREOF TO ENHANCE IMPLANTATION AND DEVELOPMENT OF EMBRYONIC CELLS Gough Nicholas M; Willson Tracey A; Seamark Robert F North Balwyn, AUSTRALIA Assigned to Amrad Corporation Limited PCT No. PCT/AU90/00001 Sec. 371 Date Aug. 29, 1991 Sec. 102(e) Date Aug. 29, 1991 PCT Filed Jan. 9, 1990 PCT Pub. No. WO90/08188 PCT Pub. Date Jul. 26, 1990. The present invention relates generally to the isolation of leukaemia inhibitory factor (LIF) genes from livestock species, the expression of said genes in recombinant vectors and the isolation of the recombinant LIF molecules and the use of livestock species LIF to enhance the in vitro development of an embryo to the implantation stage. 5418164 SELF-SUPPORTING CARRIER- FREE CELL GRANULATES FOR COMBATING PESTS AND TREATING PLANTS Andersch Wolfra; Hartwig Jurgen; Homeyer Bernhard; Stenzel Klaus Cologne, GERMANY Assigned to Bayer Aktiengesellschafi An agent for combating pests and for protecting plants comprising a carrier-free cell granulate of a microorganism which is suitable for combating pests or for plant treatment such as fungi or bacteria which are capable of mycelium formation, e.g. Deuteromycetes and Metarhizium including the new anisopliae strains DMS 3884 and 3885. 5418165 COLD TOLERANT TRICHODERMA McBeath Jenifer H Fairbanks, AK, UNITED STATES Assigned to The University of Alaska- Fairbanks The invention includes a new, cold tolerant strain of mycoparasite Trichoderma and mutants that are resistant to a pesticide to which the Trichoderma isolate is sensitive. These novel Trichoderma are capable of parasitizing fungi which are pathogenic to plants. They are also capable of producing proteinaceous, antimycotic substances which can inhibit the growth of plant pathogenic fungi. Cold tolerant Trichoderma and its biotypes can be used in, but not limited to, controlling fungal plant disease. 5419907 PATHOGENIC PORCINE RESPIRATORY CORONAVIRUS Paul Prem S; Vaughn Eric M; Halbur Patrick G Ames, IA, UNITED STATES Assigned to Iowa State University Research Foundation Inc PATENT ABSTRACTS 387 The present invention provides a biologically pure culture of a novel pathogenic porcine respiratory coronavirus (PRCV) and a vaccine derived therefrom effective against PRCV infection and transmissible gastroenteritis virus (TGEV) infection. 5420031 GYPSY MOTH VIRUS WITH ENHANCED POLYHEDRA PRODUCTION STABILITY Slavicek James M; Mercer Melissa J Dublin, OH, UNITED STATES Assigned to The United States of America as represented by the Secretary of Agriculture A virus having the identifying characteristics of ATCC VR2396 is disclosed. This virus has the trait of enhanced polyhedra production stability and resists forming a few polyhedra mutant virus. A method of protecting crops from insects comprising applying an insecticidally effective amount of virus having the identifying characteristics of ATCC VR2396 is also disclosed. 5422106 METHOD OF CONTROLLING COLEOTERA USING BACILLUS THURINGIENSIS STRAINS MG P- 14025 AND LMG P-14026 Lambert Bart J; Jansens Stefan K; Peferoen Marui Beernem, BELGIUM Assigned to Plant Genetic Systems N V Two new Bacillus thuringienses strains, LMG P- 14025 and LMG P-14026, produce insecticidal components that are toxic to Coleoptera, more particularly toxic to Diabrotica spp. The strains themselves, their sporulated cultures, or their insecticidally effective components can be used as the active ingredient in an insecticidal composition for combatting Coleoptera, more specifically Diabrotica species. 5422107 TRICHODERMA HARZIANUM SK-55 FUNGUS, FUNGICIDE CONTAINING IT, AND METHOD OF MANUFACTURE OF THE SAME AND ITS USE Kubota Terumas Kawachinagano, JAPAN Assigned to Hokkaido Green Kosan Incorporated The fungus Trichoderma harzianum SK-55 provides broad antagonistic interaction against plant pathogenic diseases, and may be used to control fungal diseases in plants. A fungicidal composition contains Trichoderma harzianum SK- 55 isolated from the soil. A method of manufacturing a fungicidal composition comprises introducing a large quantity of Trichoderma harzianum SK-55 into a culture medium, incubating it on the culture medium at a specific temperature range and at a specific humidity for a specific period of time, drying it at a specific low temperature range,
