Xa iimeko zendalo, ichibi endalo Yersinia yayintsholongwane eyosulela - namabuzi zasendle. Oku, gophers, hamsters. Xa izicwangciso ezisezidolophini, isifo bezandlala amabuzi ndiyingwevu, obomvu nomnyama. Kodwa ke kukho ichibi usulelo. Umdlali ophethe kweso sibetho intakumba ibuzi eqhelekileyo. Magciwane ngenisa egazini nge ituwa izinambuzane kufwaya. Ukususela fomu yabantu pulmonary luyasuka ebantwini. Usuleleko kwenzeka ikakhulu kukudibana ngqo izilwanyana eziphilayo okanye ufile okanye iimveliso kunye nezinto zendlu, Yersinia ungcoliseko. rhoqo Ngaphantsi iimeko balo matshinana emoyeni ugqithiso.
Ngqo kwindawo ukuqaliswa isibetho iintsholongwane akukho lutshintsho zophendlo lwezifo mbaleko. Ihlasela - isifo kakhulu echaphazela ezalathelwe nkovu. Ngoko ke, yonke inkqubo usulelo iza kuphuhliswa khona. Xa kufutshane kwindawo isango nkovu node wavelisa kwiindawo ezincinane necrosis. Oku sisiphumo inyathelo ancedisana eliyingxondorha umzimba isibetho "murine" yoluvo. Okulandelayo, isigulane iphuhlisa periadenit. Nkovu node - bubo - ukunyuka ngobukhulu, mhlawumbi kulandele suppuration sisithethi sembeko.
Zininzi iintlobo ezahlukeneyo zophuhliso izifo ezifana nenyumoniya.

Ngokuqhelekileyo, oko luhlobo yesibini ukuvela sizoku lwisana esikhumbeni okanye sisibetho ukudumba. Kulo mzekelo ogulayo kwingxaki ngokohlobo yosulelo ukopha necrotizing. isibetho Secondary inyumoniya kwenzeka kuhlobo pneumonia.
Mhlawumbi, imithi kuyaziwa izifo ezininzi kangaka eliyingozi isibetho. Iimpawu zesi sifo ngqo kakhulu kwaye zizakuxhomekeka kwasendaweni lwe gciwane.

Izigulane ofunwa yintloko ebuhlungu, kukho petechiae ezininzi. Kwakhona nokwadala udakada kunye nemithambo yegazi. Ifom cutaneous isifo kunqabile kakhulu. Kakhulu ngakumbi eqhelekileyo isibetho ukudumba. Ngefomu kwezonyango sifo-resistant yaye ayila nangokurhala lokugxininisa esiludumbo nkovu. Wabumba ekuthiwa-buboes. Bona ibuhlungu kakhulu Ngokucofa. Xa uhlobo yokubolisa ephawulwe ukubunjwa akukho namnye kodwa nakujoliso olutsha eziliqela zosulelo. izifo isibetho ebantwini (umfanekiso lwezonyango ingabonwa kubalawuli zonyango) has a sabulala eliphezulu kwaye ukukwazi okubangela izifo. Kodwa kubalulekile ukuphawula ukuba kwiminyaka engama-50 edlulileyo, oko kubhalwe kuphela kwamanye amazwe aseAfrika.
