Inhlupheko - isifo i nature esithathelanayo. It isifo anthroponotic kuthinta uhlelo lymph, emaphashini, isikhumba kanye nezinye izitho. Kuye owaziwa kusukela ezikhathini zasendulo eminyaka ehlukene phakathi kubhubhane wathumba izinkulungwane ngisho nezigidi zabantu.
Inhlupheko - isifo oyingozi ngokukhethekile. lwegciwane Ezazimzungezile - bacterium bohlobo lwe-Iersinia (Pasteurella) pestis. Y. pestis kungokwalabo umndeni Enterobacteriaceae. Emit foci ezahlukene zesifo (zemvelo, idolobha). Ngo izimo zemvelo, kwesigubhu engokwemvelo Yersinia pathogenic - namagundane zasendle. Lokhu, gophers, hamsters. Ngo izilungiselelo ezisemadolobheni, lesi sifo basakaza amagundane grey, ezimnyama. Kodwa kuba ichibi ukutheleleka. A esinegciwane kuyinto evamile rat zigcwele. Amagciwane faka ekusakazeni igazi ngokusebenzisa indle izimuncagazi ukunwaya. Kusukela wayevuka esesimweni somuntu yamaphaphu is zidlulele kubantu. Lesifo kwenzeka ngokuyinhloko ukuxhumana ngqo nezilwane bukhoma noma efile noma imikhiqizo kanye izinto zasekhaya, Yersinia ukusilaphazeka. Ngaphansi ngiphikelela kaningi kangakanani amacala sisemoyeni ukudluliswa indlela.
Ngqo indawo isingeniso zezinhlupho amagciwane akukho izinguquko sokugembula babonakala. Ezihlupha - isifo ngokuyinhloko kuthinta ISIZINDA lymph. Ngakho-ke, yonke inqubo ukutheleleka ezothuthukiswa khona. Esikhathini esiseduze lendawo kwesango lymph node ekhiqizwa izindawo elincane necrosis. Lokhu kuwumphumela isinyathelo izicubu zomzimba eziqinile uhlupho "murine" ushevu. Ngokulandelayo, isiguli eba periadenit. Lymph node - bubo - inyuka ngobukhulu, mhlawumbe kulandele wawo wokuvula suppuration.
amafomu eziningana ezahlukene zentuthuko izifo ezifana lesi sifo. Lesi sifo kwenzeka uma ufaka namagciwane abangela izifo of foci (buboes noma isikhumba) nge ukugeleza kwegazi emaphashini lomuntu siqu. Njengomthetho, kuba ifomu lesibili esakheka ngokumelene okwenza kwesikhumba noma ubhadane lwesifo sezimbilapho. Kulokhu isiguli kwetintfo ngesimo oluhambisana necrotizing ukutheleleka. Secondary lesi sifo kwenzeka ngohlobo nenyumoniya.
Mhlawumbe, kwezokwelapha it is izifo hhayi ngakho abaningi kuyingozi ukwedlula isifo esaziwayo. Izimpawu zesifo acace kakhulu futhi ancike kwasendaweni we lwegciwane. Isikhathi bayashintshana ekufukameleni ngokuvamile izinsuku ezingu-6. Lesi sifo cishe alikho nhlobo ifomu okungamahlalakhona, it is asathuthuka ngejubane umbani. Uphawu lokuqala - ukudakwa oyingozi. Iziguli ngokuthi ikhanda ezinzima, kukhona petechiae amaningi. Futhi abathintekayo ubende kanye uhlelo senhliziyo nemithambo yegazi. Ifomu cutaneous lesi sifo ivelakancane. Okuningi ezivamile nesifo sezimbilapho. Ngesimo esinjalo emitholampilo ye isifo ukumelana futhi kwakhiwa i ukuvuvukala okukhulu node-lymph. Kumiswa buboes okuthiwa. Ziyakwazi kubuhlungu ku palpation. Ngesimo ukonakala imakwe kumiswa hhayi elilodwa foci eziningana ukutheleleka. isifo Inhlupho abantu (isithombe emtholampilo ingabonwa lwemibhalo wezokwelapha) has a high nokufa rate kanye nekhono kubangele kubhubhane. Kodwa kuyafaneleka ukuthi kule minyaka engu-50 edlule, waloba kuphela emazweni athile ase-Afrika.
