Ososayensi bafundele amathambo angaphezu kwezinkulungwane ezingama-69 ezinhlamvu ezahlukene
Iqembu lochwepheshe lihlaziye iminonjana yezifo ezisele emathanjeni omuntu, okwenza ukuthi kube nokwenzeka ukulandelela inqubo yokuziphendukela kwemvelo ukulwa namagciwane ahlukahlukene. Imiphumela yesifundo esikhulu savela kumagazini kaPlos One.
Izinto eziphambili zomsebenzi wesayensi kwakunguchoko, isifo sofuba kanye ne-treponematosis. Le ndawo yiqembu lezifo ezibandakanya i-syphilis. Isici salezi zifo amandla abo okushiya amathrekhi emathanjeni namazinyo. Lokhu kwavumela ochwepheshe ukuthi balandele amandla ashukumisayo wokuthuthukiswa kwezifo ezizukulwaneni ezifika kwezingu-200. Njengoba uMatsa Henneberg, ongudokotela we-anthropologist wase-University of Fliinders e-Australia, ukwanda kwalezi zifo kuncishisiwe njengoba zivumelana ngokuhlangene. Inqubo enjalo inomthelela ekusindeni kwamagciwane nomuntu ophethe ngayo.
Eminyakeni engama-5000 edlule, ngaphambi kokuvela komuthi wanamuhla, izimpawu zamathambo zesifo sofuba zaba ngaphansi futhi zivame kakhulu; Ukubonakaliswa kwamathambo kochoko e-Europe kwaqala ukwehla ngemuva kweNkathi Ephakathi; Futhi izimpawu zamathambo ze-treponematosis eNyakatho Melika ziye zancipha eminyakeni yamuva nje ukuxhumana nabantu baseYurophu abahlaselayo, - i-anthropologist evela e-University of Fliinders e-Australia, umbhali ocwaningweni.Njengengxenye yomsebenzi wesayensi, kwasetshenziswa imiphumela yezifundo zakuqala zezifo ezifundwayo, lapho ochwepheshe bahlaziye amathambo angama-69,379. Izinsalela zabantu zazingezinhlobonhlobo ezahlukahlukene, kusukela ngo-7250 BC. e. Futhi uphela ngamathambo abantu besikhathi sethu. Kuyaqapheleka ukuthi akuzona zonke izinsalela ezingaphansi kokutheleleka ngesinye sezifo ezintathu, kepha usayizi omkhulu wesampula avunyelwe ochwepheshe ukwenza iziphetho eziningana zesayensi.
Kwatholakala ukuthi azikho kulezi zifo ezintathu ezabulala umuntu ngokushesha. Lokhu kwavumela amagciwane ukuze asinde futhi asakaze. Kodwa-ke, ukwehla kwezibalo kokwanda kwesifo sofuba, uchoko kanye ne-treponematosis kunikeza izizathu zokucabanga ukuthi abantu bakhule ukumelana nalawa magciwane, noma izifo ngokwazo seziyingozi.
Ngombono wokuziphendukela kwemvelo, ngoba ama-pathogen anengqondo ukudala ukulimala okuncane kumnikazi, ngakho-ke ukusinda okuphezulu kuncike, ngakho-ke kubonakala sengathi amazinga aphezulu okudlulisela kubonakala sengathi angowesikhashana we-Evoluly I-Flinders University, umbhali ongumhlangano wesifundo.Ochwepheshe baphawule ukuthi ukuhlaziya ukuvela komzimba womuntu kanye namagciwane, kuyadingeka ukubheka izinto eziningi ezahlukahlukene ezingathinta ukusakazeka kwezifo. Naphezu kweqiniso lokuthi ucwaningo olusha akuyona into eqinile ye-epidemiological, imiphumela yayo izokwazi ukusiza ochwepheshe esikhathini esizayo ukuze bakhombe izizathu zokwakhiwa kwamagciwane amasha.
