A different set of dissection instruments was used for each animal. Cultures were incubated at 10 °C–16 °C and examined for cytopathic effects (CPE) daily for 7–10 days. Cultures that did not exhibit CPE were blind passed at least once before being classified as negative. Cultures that exhibited CPE were frozen at −80 °C and thawed three times, and cellular debris was removed by centrifugation at 1000 g for 30 min at 4 °C. For electron microscopic analysis, aliquots of the supernatant were re-centrifuged at 100 000 g for 10 min in a Beckman Airfuge (lndianapolis, CA, USA). The pelleted viral particles were negatively stained with 2% phosphotungstic acid and examined in a Hitachi H-7600 transmission electron microscope (Schaumnberg, lL, USA).","tracks":[{"project":"2_test","denotations":[{"id":"27599472-10603206-27784053","span":{"begin":263,"end":264},"obj":"10603206"},{"id":"27599472-19409947-27784054","span":{"begin":532,"end":535},"obj":"19409947"}],"attributes":[{"subj":"27599472-10603206-27784053","pred":"source","obj":"2_test"},{"subj":"27599472-19409947-27784054","pred":"source","obj":"2_test"}]},{"project":"MyTest","denotations":[{"id":"27599472-10603206-27784053","span":{"begin":263,"end":265},"obj":"10603206"},{"id":"27599472-19409947-27784054","span":{"begin":532,"end":535},"obj":"19409947"}],"namespaces":[{"prefix":"_base","uri":"https://www.uniprot.org/uniprot/testbase"},{"prefix":"UniProtKB","uri":"https://www.uniprot.org/uniprot/"},{"prefix":"uniprot","uri":"https://www.uniprot.org/uniprotkb/"}],"attributes":[{"subj":"27599472-10603206-27784053","pred":"source","obj":"MyTest"},{"subj":"27599472-19409947-27784054","pred":"source","obj":"MyTest"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93a6ec","default":true},{"id":"MyTest","color":"#c0ec93"}]}]}}
