| outbreaks of fowl cholera in muscovy ducks (cairina moschata) on a farm in aomori prefecture. | outbreaks of a subacute disease characterized by lameness, corneal turbidity, dysstasia and depression occurred in muscovy ducks (cairina moschata) on a farm in aomori prefecture in february and may 1991. nine strains of pasteurella multocida were isolated from 5 to 6 dead ducks, and 4 of 8 ducks with clinical signs. serotypes of the isolates were identified as heddleston's serotype 1, 10 or 12 and namioka's serotypes 5:a, 8:a, 9:a or 9:ut. these isolates were highly susceptible to 12 antibiotic ... | 1996 | 8777238 |
| monitoring of dsp toxins in small-sized plankton fraction of seawater collected in mutsu bay, japan, by elisa method: relation with toxin contamination of scallop. | monitorings were conducted on dsp toxins in mid-gut gland of scallop (mouse assay), cell numbers of toxic dinoflagellate species of dinophysis, and diarrhetic shellfish poisoning (dsp) toxins in small-sized (0.7-5 microm) plankton fraction of seawater collected from surface (0 m) and 20 m depth at a station in mutsu bay, aomori prefecture, japan, in 2000. a specific enzyme-linked immunosorbent assay (elisa) was employed for the analysis of dsp toxins in small-sized plankton fraction using a mous ... | 2003 | 12787606 |
| genotoxic assessment of small mammals at an illegal dumpsite at the aomori-iwate prefectural boundary. | in 2003, we examined the chromosomes of grass voles at an illegal dumpsite at the aomori-lwate prefectural boundary. in subsequent years, from 2003-2006, we surveyed the chromosomes of four species of small mammals, namely, the japanese grass vole (microtus montebelli), the large japanese field mouse (apodemus speciosus), the small japanese field mouse (a. argenteus), and the greater japanese shrew mole (urotrichus talpoides). each annual survey revealed, both on a yearly basis and during the en ... | 2009 | 19341331 |
