Akazi kasohotse mu kinyamakuru cyo muri Amerika genetiki y'abantu. Mu myaka ibihumbi n'ibihumbi ishize, abantu ntibagize imihindagurikire y'ikirere, ahubwo banagize icyorezo cyose, harimo igituntu, icyorezo n'ibicurane byo muri Esipanye. Muri icyo gihe, igituntu giterwa na tuberculose yanjye ya mycobacterium akomeje kuba imwe mu mpamvu nyamukuru zitera abantu ku isi yose ku isi (ukurikije abantu barenga miliyoni 1.5 barapfa).
Ubu bwanduye bufatwa nkumwe mu mateka yica mu mateka - mu myaka ibihumbi bibiri ishize abantu barenga miliyari imwe baramupfa. Ariko, imiterere n'umuvuduko wo guhura na koche kuri twe tugakomeza kutamenyekana. Abahanga bo mu kigo cya Pasteur na kaminuza ya Pasris (Ubufaransa) basesenguye amakuru y'abaturage mu rwego rwo gusobanukirwa uburyo guhitamo bisanzwe byagize ingaruka kareho.
Ubushakashatsi buherutse gukorwa bwerekanye ko verisiyo ya Tyk2 yitwa P1104a, ifitanye isano no guhura n'indwara nyuma yo kwandura Koch. Ukoresheje ibintu byinshi by'amakuru aturuka ku gihumbi kirenga igihumbi cy'umuntu wa kera, abahanga basanze ari bwo buryo bwa P1104a ku bwa mbere bagaragaye mu myaka irenga ibihumbi 30 ishize kandi babyaye abakurambere muri rusange.
Isesengura ryerekanye ko inshuro zibi zagabanutse cyane hashize imyaka ibihumbi bibiri ishize. Icyo gihe nibwo buryo bugezweho bwo gutwara igituntu cya Mycobacterium bwatangiye gutsinda. Abanditsi b'ubushakashatsi bamenye ko mu gihe cy'umuringa, p1104 va divane ya gene yari isanzwe yari isanzwe kuruta uyu munsi. Kandi birashoboka ko byatewe no kwiyongera kwa Igituntu mubantu bo muricyo gihe.
Nyuma y'ibiciro binini by'abahinzi ba Anatoliya n'abahinzi ba Euragean mu Burayi mu myaka icumi ishize, P11044000404ya yahise ihindagurika. Ariko hashize imyaka igera ku bihumbi bibiri, guhitamo nabi gukabije byatangiye, byagabanije ikwirakwizwa rya divayi ya 20 ku ijana, rishobora kwitwa kimwe mubyo rugaragara cyane muri genome ya muntu.
