Pomoc\u00ed molekul\u00e1rn\u00edch metod a celogenomov\u00e9ho sekvenov\u00e1n\u00ed auto\u0159i sledovali nejen samotnou p\u0159\u00edtomnost viru, ale tak\u00e9 zm\u011bny jeho genetick\u00e9 struktury v \u010dase a prostoru.<\/p>\n

Jak se virus udr\u017euje v p\u0159\u00edrod\u011b<\/h6>\n

V\u00fdsledky ukazuj\u00ed, \u017ee virus se v jedn\u00e9 lokalit\u011b vyskytoval opakovan\u011b po cel\u00e9 sledovan\u00e9 obdob\u00ed. Genetick\u00e1 anal\u00fdza nicm\u00e9n\u011b nazna\u010dila, \u017ee jeho p\u0159etrv\u00e1v\u00e1n\u00ed nen\u00ed statick\u00e9 \u2013 virus se m\u016f\u017ee vym\u011b\u0148ovat mezi sousedn\u00edmi populacemi my\u0161\u00ed, a to i p\u0159es jejich relativn\u011b omezen\u00fd pohyb v krajin\u011b.<\/p>\n

\u201eProk\u00e1zali jsme, \u017ee i velmi lok\u00e1ln\u011b roz\u0161\u00ed\u0159en\u00fd virus m\u016f\u017ee v p\u0159\u00edrodn\u00edch podm\u00ednk\u00e1ch p\u0159etrv\u00e1vat des\u00edtky let. To je d\u016fle\u017eit\u00e9 nejen z hlediska virologie, ale i pro pochopen\u00ed dlouhodob\u00fdch rizik pro lidsk\u00e9 zdrav\u00ed,\u201c<\/em> \u0159\u00edk\u00e1 Jo\u00eblle Go\u00fcy de Bellocq, vedouc\u00ed t\u00fdmu z \u00dastavu biologie obratlovc\u016f AV \u010cR (\u00daBO AV \u010cR).<\/p>\n

Z\u00e1sadn\u00ed roli v tomto procesu hraje pravd\u011bpodobn\u011b samotn\u00e1 biologie hostitele. My\u0161i dom\u00e1c\u00ed \u017eij\u00ed v mal\u00fdch, relativn\u011b uzav\u0159en\u00fdch skupin\u00e1ch a virus se u nich m\u016f\u017ee p\u0159en\u00e1\u0161et tak\u00e9 z matky na potomstvo. Tento tzv. vertik\u00e1ln\u00ed p\u0159enos umo\u017e\u0148uje viru dlouhodob\u011b p\u0159e\u017e\u00edvat v konkr\u00e9tn\u00edm m\u00edst\u011b i bez nutnosti \u010dast\u00e9ho p\u0159enosu mezi dal\u0161\u00edmi oblastmi.<\/p>\n

Dopady na ve\u0159ejn\u00e9 zdrav\u00ed<\/h6>\n

Z hlediska ve\u0159ejn\u00e9ho zdrav\u00ed je kl\u00ed\u010dov\u00e9, \u017ee riziko n\u00e1kazy \u010dlov\u011bka je sice geograficky omezen\u00e9, ale \u010dasov\u011b stabiln\u00ed. To znamen\u00e1, \u017ee i po mnoha letech m\u016f\u017ee virus v dan\u00e9 oblasti znovu p\u0159edstavovat potenci\u00e1ln\u00ed hrozbu.<\/p>\n
