Nezhizha richisvika nekukurumidza kupfuura zvaungati 'beach bod', kutya kurwiswa kweshark kunozosimudza musoro waro wakapinza zvakare. Zvakadaro kune ese hubbub yakavakomberedza, iyo chaiyo frequency yekurwiswa muUnited States ndeye, uye yaramba, inonyadzisa yakaderera. makumi mashanu nenhatu chete akatendeseka, kurwiswa kusiri kupomerwa kwakanyorwa muna 2013, sekureva kweShark Research Institute.

Aiwa, kana totaura nezvengozi dzakajeka uye dziripo dzinobva mumhuka dzomusango munguva yechirimo, shaki inotyisa inochenuruka kana ichienzaniswa nechisikwa chine makumbo masere maduku akawanda pane ayo, chikwekwe. Nepo kurumwa kwavo kungave kwakapfava, akasiyana ehutachiona avanogona kuparadzira neimwe neimwe, kusanganisira avo vane mhosva yeChirwere cheLyme, chokwadi havana. Uye kana yambiro ichangoburwa kubva kuIndiana University Bloomington (IUB) vaongorori vakabereka chero muchero, izvi zvikwekwe 'nzvimbo yesimba inongokura muhukuru sezvo mamiriro edu ekunze anodziya.

A Rising Tide

Kunyangwe iyo Centers for Disease Control and Prevention (CDC) yakataura gore rega rega makumi maviri, 000 kusvika 30, 000 zviitiko zvechirwere cheLyme kwemakore gumi apfuura, ivo pachavo vanoyambira kuti huwandu hwavo hunogona kunge hwakanyanya kudzikisira kupararira kwechokwadi kweLyme, kunyanya. zvinokonzerwa nebhakitiriya Borrelia burgdorferi kuburikidza nekurumwa kwechikwekwe chine makumbo matema (Ixodes scapularis neIxodes pacificus). Muchiziviso chayo chaMay seMwedzi Wekuzivisa Chirwere cheLyme, CDC yakatsanangura kuti tsvagiridzo inoratidza mazana matatu emazana ezviitiko zveLyme zvinorapwa uye kuongororwa gore rega rega.

Asi Lyme handiyo yega chirwere chinoparadzirwa nezvikwekwe. Nepo Lyme ichiwanzo onekwa nechepakati pemadokero, New England, uye pakati peAtlantic nyika, nyaya dzemaodzanyemba-inosanganiswa nerwere chirwere (STARI) dot kumabvazuva, maodzanyemba kwakadziva uye maodzanyemba-pakati nyika, inopararira neiyo imwe nyeredzi chikwekwe, Amblyomma americanum. Zvikwekwe izvi zvakare zvakabatanidzwa netambo yezvirwere zvichangobva kuwanikwa, kusanganisira hutachiona hweHeartland kuMissouri, uye mate ayo ega anofungidzirwa kuti anokonzera kusawirirana kwenyama mune vamwe vanhu.

Kwete kuti ibude pachena, mhuri yeIxodes yezvikwekwe yakabatana nekubuda kwe babesiosis uye chirwere chePowassan virus. Zvirwere izvi zvinosiyana mukuomarara kwazvo, asi kubva mukuremara kuneta mwedzi mushure mekurapwa nemishonga inorwisa mabhakitiriya kusvika kukukuvara zvachose kwetsinga uye kunyange kufa. Kusiyana-siyana kwezvirwere zvinogona kuparadzirwa kuburikidza nezvikwekwe zviri nyore zvinoita kuti ive yakanyanya kupesvedzera chirwere chevector muUS, yechipiri chete kune mosquito pasi rese.

Uye maererano naDr. Keith Clay, Purofesa Anoremekedzwa muIndiana University Bloomington College of Arts and Sciences 'Dhipatimendi reBiology, tiri kungowedzera kushamwaridzana navo. "Mumakore gumi apfuura, tiri kuona zvinhu zvichichinja zvakanyanya," Clay akadaro mukuburitswa kwenhau nekoreji, "Wakanga usingamboona zvikwekwe zvenyeredzi imwe chete muIndiana; zvino zvakajairika. Mumakore gumi, isu tingangoonawo Gulf Coast tick pano zvakare. Pane dzidziso dzakawanda dzekuti sei izvi zviri kuitika, asi chikuru ndechekuchinja kwemamiriro ekunze."

Tsvagiridzo yakaitwa neClay Lab kuIUB yakaongorora zvakanyanya kuti kudyidzana pakati pezvipenyu, kunyanya tupukanana, kunogona kukanganisa sei ecology yenharaunda, kana kunyange iyo yerudzi rwega. Kwanga kuri kuedza kwavo mukudzidza nyika ine utachiona mukati mezvikwekwe zvakavabvumira kuona mafambiro ekuchinja pakati pehuwandu hwavo. "MuIndiana, chikwekwe chine makumbo matema chiri kupinda chichibva kuchamhembe uku nyeredzi imwe chete ichipinda kubva kumaodzanyemba," vaongorori veClay Lab vakanyora.

Imwe tsvagiridzo yakadzokorora mhedziso dzakafanana, kunyangwe nezvenzvimbo dzakasiyana dzepasi. "Nhamba yenzvimbo dzinozivikanwa dzechirwere cheLyme muCanada dziri kuwedzera nokuti huwandu hweI. scapularis huri kuwedzera kumapurovhinzi ekumabvazuva nepakati," chidzidzo che2009 kubva kuCanada Medical Association Journal yakagumisa. Uye sangano reIntergovernmental Panel on Climate Change (IPCC), riri muchikamu chiri kuongorora zvingangokanganisa shanduko yemamiriro ekunze pautano hwevanhu, rinoti kuwedzera kwezvikwekwe kuNorth America neEurope kwakamboonekwa mumakore makumi maviri apfuura. humbowo hunoratidza kuwirirana pakati pechando chakanyorovera muSweden kubva 1980 kusvika 1994 nekuwanda kwekukura kwekwekwe.

Hapana Pfuti Yekusvuta

Kunyangwe zvese izvo, zvichiri kukurumidza kuzivisa kubatana kwepfuti pakati pekushanduka kwemamiriro ekunze uye zvirwere zvinotapuriranwa nezvikwekwe. Muongororo yakaitwa muna 2015 yakabudiswa muPhilosophical Transactions B, vanyori vanocherechedza kuti kunyange zvazvo zvidzidzo zvakawanda zvakawana humbowo hwekubatana pakati pekudziya kwekushisa uye zvirwere zvinokonzerwa nezvikwekwe zvinoparadzirwa nekakwekwe-nemakumbo matema, pane zvakawanda zvakanyanyisa kufungidzira zvakaitwa nezvidzidzo izvi. kuti tikwanise kusvika chero mhedziso dzakasimba.

Imwe tsvagiridzo yakatsamira panzira dzemurabhoritari kudzokorora mamiriro akanakisa ezvakatipoteredza ekukura kwekwekwe, asi zvinogona kunetsa kushandura mhedzisiro yavo kumamiriro ehupenyu chaihwo. Vanyori vanonyatsoratidza kuti kunyange nzvimbo ingave yakaoma uye yakaoma, mamiriro asina kunaka kune dema-makumbo chikwekwe, vanogona kuwana hunyoro mumashizha emashizha kana ivhu. Uye kuedza kugadzira dzidziso dzekukura kwekikwe kunoenderana neakasiyana ezvakatipoteredza zvinogona kukonzera mhedziso dzakasiyana, vanyori vachiona kuti nepo imwe modhi yakafanotaura kumadokero kutama kwezvikwekwe nekushanduka kwemamiriro ekunze, mumwe akafanotaura kuti zviitiko zveLyme zvaizowedzera zvakanyanya. nzvimbo dzekumabvazuva neMidwestern United States.

Mune mamwe mazwi, kunyange zvazvo zvichida kuti kupisa kwekushisa kune uye kuchaparadzira zvikwekwe kune dzimwe nzvimbo dzenyika; isu hatinyatso nzwisisa kuti izvi zvichaitika sei uye kupi chaizvo. Uye isu hatizodaro kudzamara tamisa mwero uri nani wekutsvagisa unoverengera kusangana kwakaoma kwemamiriro ekunze pane kwete chete chikwekwe, asi vanhu, pathogen, uye dzimwe mhuka dzinotambira, vanyori vanoyambira. "Kunzwisisa kwemamiriro ekunze pane vector uye pathogen kuchabvumira vaongorori kufanotaura kuti njodzi yekusangana nevanhu kune hutachiona uhu ichachinja sei sezvo mamiriro ekunze ari kuramba achichinja," vakanyora kudaro.

Nekuda kwavo, Clay Lab yakaedza kunzwisisa kuti nharaunda yemicrobial, inowanzonzi microbiome, yechikwekwe inogona kukanganisa hupenyu hwayo chete, asi pamwe kurwisa kubuda kwehutachiona hunokonzera chirwere nekuwedzera huwandu. yeutachiona husingakonzere zvirwere hunozivikanwa semasymbionts anowanikwa muchikwekwe. "Kunzwisisa microbiome yechikwekwe kuri kuisa hwaro hwekutsvagisa mune ramangwana," aimbove mudzidzi weClay Lab akapedza kudzidza uye azvino anotsvakurudza paUniversity yeEdinburgh Evie Rynkiewicz akati, "Kune mapoka ari kushanda izvozvi kuunza symbionts muumhutu 'microbiome kudzivirira. kana kuderedza huwandu hweutachiona huri muhurongwa hwavo hunobata vanhu.
