I-Diarrhea enegazi elibangelwa yi-E. Coli

Nangona kungabonakaliswa njengobangela wesifo se-colitis (uhudo lwegazi) kude kube ngo-1982, u- E. coli O157: I-H7 ngoku ibonwa njengesizathu esiqhelekileyo sale meko. Ukuqubuka kwe-colitis obangelwa yi-bhaktheriya iye yadibaniswa ne-hamburger ecocekileyo, ijusi ye-apula, kunye nemveliso yobisi engaphunyekanga. Nangona uninzi lwasuleleko luyinto engathí sina kwaye luyicombulule ngokwabo, iingxaki ezinokuthi zenzeke zingenzeka emva kokusuleleka ngu- E. coli O157: H7.

Igama lohlobo: I-Esoriororhagic Escherichia coli , okanye i- "EHEC"

Uhlobo lweMicrobe: Ibhakteria ye-Gram-negative

Indlela Esasazeka ngayo

Ngokuqhelekileyo ukutya.

Ukutya okuhambelana no- E. coli kuye kwabandakanya inyama ecocekileyo okanye engadliwayo (umzekelo, inyama yenkomo), ukutya okunomsoco, iindizi zezityalo kunye neziveliso zobisi, kwaye zivelise. Ezinye izibonelelo zentsholongwane zibandakanya izilwanyana zokuthambisa, i-lake yamanzi kunye nezandla ezingcolileyo.

Ngubani Osemngciphekweni?

Bonke abantu banomdla kwisifo, kodwa abaselula kunye nabaludala kakhulu basengozini enkulu yezifo ezinzulu.

Iimpawu

Iimpawu ziyahluka, kodwa ngokuqhelekileyo ziquka ukuhanjiswa (ngokuqhelekileyo kugazini), ukuhlanza, kunye neengqumbo zesisu ezinzima. Ngokuqhelekileyo, umkhuhlane awukho okanye unobumnene kakhulu. Kubantu abaninzi, usulelo luya kugqiba malunga neentsuku eziyi-8.

Indlela Ebangelwa Izifo

U-E. coli unamathela kwiiseli zamathumbu kwaye avelise i-toxin (i-toxin yaseShiga) ebangela ukuvuvukala nokukhuselwa kwamanzi emathumbu. I-toxin nayo ibonakalisa i-tissue lining of the intestine enkulu kunye neentso.

Iingxaki

Malunga no-5-10% wabantu abane- E. coli O157: Izifo zokuhlaselwa kwe-H7 zihlakulela ingxaki enokuthi yingozi ebizwa ngokuba yi-hemolytic-uremic syndrome , okanye i-HUS, ebonakala yintliziyo okanye ukungaphumeleli komntu kunye ne-hemolytic anemia (ukulahlekelwa kweeseli ezibomvu zegazi). Le meko isoloko ibonakala kubantwana kwaye ingaba yinto ebalulekileyo, ekhokelela ekumonakalisweni kwintliziyo okanye ekufeni.

Ukuxilongwa

Ukuvavanywa kwebhanki yeesampuli zesebe kwenziwa ngeentlobo zebhaktheriya.

Prognosis

Uninzi lwasuleleko luzinyathelo ngokwabo kwiintsuku ezingama-5 ukuya kwezingama-7 ngaphandle kokonyango, kodwa ezinye izifo ziyakunzima okanye zisongela ubomi.

Unyango

Unyango lubandakanya ukunakekelwa okuxhasayo, ngokukodwa, ukuphepha ukungcoliswa kwamanzi ngokulawula amanzi. Amayeza okulwa ne-antibiotics kunye nee-anti-diarralal (ezifana ne-Imodium) ayilunyanzelwanga ngokunyanga kwi- E. coli i- O157: izifo ze-H7. Ukusetyenziswa kwezi nyeza kuye kwadityaniswa nokugula okukhulu; Kubonakala ukuba, banokulwandisa ubude behudo, banokubangela umphumo we-toxin yeShiga, kwaye bandise ingozi ye-hemolytic-uremic syndrome.

Thintelo

Sebenzisa ucoceko olufanelekileyo, ukuhlamba izandla rhoqo kunye neendlela zokukhusela ekhishini .
