Ungakwazi yini Ukubamba Amagciwane Asesithweni Sangasese Sabanye Abantu Ezihlalweni Ze-Subway?

Kunezizathu eziningi zokungahlali kude nowesifazane ogqoke izikhindi zejimu ezimfushane kakhulu esitimeleni esingaphansi komhlaba. Okungenani kuwo amagciwane aqiniseke ukuthi ugcoba sonke isihlalo. Ngabe lawo magciwane ajulukile angakulimaza ngempela? Futhi kuthiwani ngezinye izindawo zomphakathi njengemishini yezandla nemishini yamathikithi? Ngabe nazo ngokuphelele, futhi? Ngokujabulisayo, ososayensi babenelukuluku lokwenele ukuthola wonke umuntu (ngoba sonke sesikhishwe ngokwanele manje).

Abaphenyi abavela kuHarvard T.H. IChan School of Public Health ihlolwe izimoto ezivela emigqeni emithathu engaphansi komhlaba eBoston ukuthola ukuthi iziphi izinhlobo zabagibeli bezitimela ezihamba ngaphansi komhlaba ezidlulayo. Akumangalisi ukuthi bathole izihlalo, izindonga nezigxobo zezimoto kanye nezikrini nezindonga eziseduze nemishini yamathikithi-yep, cishe yonke indawo-yayimbozwe ngamagciwane. Ingxenye emangazayo ukuthi izimbungulu eziningi ezazidluliswa zazingezinhle "zimbi" -okusho ukuthi zazingabhekwa njengokumelana nemithi elwa namagciwane futhi zazingenayo eminye imiphumela engase ibe yingozi. Eqinisweni, abacwaningi bathe izindawo ezingaphansi komhlaba abazigudluzayo zaziphansi kulawa ma-microorganisms akhathazayo kunalokhu okukhona emathunjini akho kakade. (Whew, and ew!) Futhi, usuvele umbozwe ngamagciwane-i-3D Bacteria Maps Prove It.

"Abantu abaphilile akudingeki bakhathazeke," kusho uTiffany Hsu, umbhali ocwaningayo kanye nomsizi wezocwaningo emnyangweni wesikole we-biostatistics. "Izimbungulu eziningi ezikhona zitholakala esikhunjeni esivamile somuntu noma kumasayithi omlomo, ngakho-ke abantu abaningi bangaziphatha nazo." Noma kunjalo, ukugeza izandla zakho ngemva kokugibela indlela ehamba ngaphansi ngeke kukulimaze, uyanezela. (Ngakolunye uhlangothi, kune-parasite eyedlulele etholwe icashe emachibini okubhukuda.)

Okutholwe nguHsu nozakwabo, okushicilelwa kuleli sonto kwi-American Society for Microbiology's journal mSystems, nikeza isisekelo samagciwane laphaya ukuze abacwaningi bakwazi ukukala izinkinga zezempilo zomphakathi ezizayo, njengokuqubuka komkhuhlane omkhulu.

Abaphenyi baphinde bathola izinhlobo ezahlukene zezimbungulu ezindaweni ezahlukahlukene. Amagciwane esikhumba nawomlomo asakazeka ngokuthimula noma ngokuthinta atholakala ngamanani aphezulu ezigxotsheni zesitimela esihamba ngaphansi komhlaba, futhi amagciwane esithweni sangasese sangasese ayekhona ezihlalweni. Inkulumo ethi "amagciwane esitho sangasese sowesifazane" ingahle ikwenze uthuke, kepha akusho ukuthi isitho sangasese somgibeli size ngokuxhumana kwesikhumba nesihlalo. Lezo zinhlobo zezimbungulu zingadluliswa ngezingubo. Futhi kungathatha okuningi ukuthi bakuthelele, kusho uHsu. Amagciwane kuzomele aqhubeke ephila, athathwe izingubo zakho endaweni lapho engaphila khona (uma kuqhathaniswa, yithi, nengalo yakho), bese eqhudelana nezinye izimbungulu ukuze athole indawo emphakathini wezinambuzane. (Yebo, ngiyaxolisa ukubika ukuthi unenani lomphakathi lezimbungulu kuwe ngaso sonke isikhathi.) Kukhona izindawo zokungcebeleka ezithile nakuba ziqukethe amagciwane namagciwane amaningi kunalokho obungathanda ukwazi ngakho-funda ngalezi zinto eziyi-10 okungenzeka ukuthi ubungeke' ngifuna ukuhlanganyela.)

Iphuzu elibalulekile: Noma indlela ehamba ngaphansi imbozwe ngamagciwane, akunakwenzeka ukuthi uzocosha amagciwane esithweni sangasese sabanye besifazane. "Okwamanje, kubonakala sengathi ngeke zidluliswe," kusho uHsu. "Isikhumba sethu namasosha omzimba ahlinzeka ngokuzivikela okukhulu!" Kuhle ukwazi, kepha akekho noyedwa ongakusola ngokuthatha isinqumo sokuma kuze kube isitobhu esilandelayo.
