De peste trei secole, caii s\u0103lbatici din Rezerva\u021bia Na\u021bional\u0103 de Flor\u0103 \u0219i Faun\u0103 Chincoteague au cutreierat insula-barier\u0103 Assateague. \u00cens\u0103, \u00een ultimii ani, a ap\u0103rut o nou\u0103 amenin\u021bare: cancerul de mla\u0219tin\u0103, o boal\u0103 letal\u0103 cauzat\u0103 de microorganismul similar unei ciuperci Pythium insidiosum. Aceast\u0103 boal\u0103 a ucis \u0219apte cai din 2017 \u00eencoace, \u00eengrijor\u00e2ndu-i pe fanii \u0219i \u00eengrijitorii hergheliei.<\/p>\n\n
Cancerul de mla\u0219tin\u0103 infecteaz\u0103 \u00een principal caii, c\u00e2inii \u0219i oamenii. Infec\u021bia are loc, de obicei, prin contactul cu apa care con\u021bine zoospori \u00eenot\u0103tori de P. insidiosum, care sunt atra\u0219i de r\u0103ni deschise. Odat\u0103 ajuns \u00een interiorul unei gazde, microbul se r\u0103sp\u00e2nde\u0219te prin filamente \u0219erpuitoare pe care le folose\u0219te pentru a se hr\u0103ni cu \u021besuturile animalului.<\/p>\n\n
P. insidiosum se g\u0103se\u0219te \u00een principal \u00een climatele tropicale. \u00cens\u0103, pe m\u0103sur\u0103 ce schimb\u0103rile climatice \u00eenc\u0103lzesc planeta, cazurile de cancer de mla\u0219tin\u0103 au \u00eenceput s\u0103 se deplaseze spre nord. Rezerva\u021bia Na\u021bional\u0103 de Flor\u0103 \u0219i Faun\u0103 Chincoteague are condi\u021bii ideale pentru acest parazit: zone umede cu ap\u0103 st\u0103tut\u0103 \u0219i temperaturi de var\u0103 care dep\u0103\u0219esc 100 de grade Fahrenheit. Testele preliminare au ar\u0103tat c\u0103 microbul este \u201edestul de r\u0103sp\u00e2ndit\u201d \u00een \u00eentreaga rezerva\u021bie.<\/p>\n\n
Ca r\u0103spuns la amenin\u021barea cancerului de mla\u0219tin\u0103, Compania de Pompieri Voluntari din Chincoteague, care de\u021bine \u0219i \u00eengrije\u0219te caii, a \u00eenceput s\u0103 testeze un vaccin \u00een 2019. Vaccinul are ca \u021bint\u0103 P. insidiosum \u0219i \u00ee\u0219i propune s\u0103 protejeze caii de infec\u021bie. De\u0219i tratamentul este \u00eenc\u0103 \u00een stadii incipiente, pare s\u0103 func\u021bioneze. Purt\u0103toarea de cuv\u00e2nt Denise Bowden a declarat: \u201eTrebuie s\u0103 continu\u0103m s\u0103 vaccin\u0103m \u00een urm\u0103torii [doi p\u00e2n\u0103 la trei] ani pentru a spune mai bine dac\u0103 acest vaccin a fost\/este un instrument eficient \u00een aceast\u0103 herghelie, \u00eempreun\u0103 cu practicile de gestionare a mediului.\u201d<\/p>\n\n
\u00cen mod interesant, urgia cancerului de mla\u0219tin\u0103 a cru\u021bat herghelia de cai de pe partea statului Maryland a insulei Assateague. Oamenii de \u0219tiin\u021b\u0103 investigheaz\u0103 dac\u0103 apa s\u0103rat\u0103 din apa st\u0103t\u0103toare de pe partea statului Maryland ar putea ucide microbul care provoac\u0103 boala.<\/p>\n\n
\u00cen fiecare prim\u0103var\u0103, caii sunt supu\u0219i unui control medical. La data de 18 aprilie, to\u021bi cei 160 de cai din Virginia erau f\u0103r\u0103 cancer de mla\u0219tin\u0103. Adunarea a vizat, de asemenea, o duzin\u0103 de cai care \u00eenc\u0103 nu primiser\u0103 vaccinul experimental.<\/p>\n\n
Richard Hansen, creatorul vaccinului, este \u201eoptimist prudent\u201d cu privire la poten\u021bialul s\u0103u de a men\u021bine caii s\u0103n\u0103to\u0219i. \u201eP\u00e2n\u0103 acum, pare s\u0103 mearg\u0103 foarte bine\u201d, a spus Bowden. \u201eNu am avut o var\u0103 extrem de umed\u0103 \u0219i ploioas\u0103 anul trecut. Cred c\u0103 \u00eentre asta \u0219i vaccin, suntem pe drumul cel bun.\u201d<\/p>\n\n
Lupta \u00eempotriva cancerului de mla\u0219tin\u0103 este \u00een curs de desf\u0103\u0219urare, dar noul vaccin ofer\u0103 speran\u021b\u0103 pentru supravie\u021buirea cailor s\u0103lbatici Chincoteague. Vaccinarea continu\u0103 \u0219i practicile de gestionare a mediului vor fi cruciale pentru protejarea acestei herghelii iconice.<\/p>","protected":false},"excerpt":{"rendered":"
