Lezi zihloko zithi inyama Edla amabhaktheriya atholakele eGulf Coast. Kusho ukuthini lokhu? Ngokuvamile, libhekisela kuVibrio Vulnificus engabangela ukutheleleka kesikhumba esibi. Kungabangela izifo zesikhumba ezinobuthi ezibizwa nge-bullae (ezingagcwaliswa ngegazi). Okukhathazayo kakhulu ukuthi kungabangela ukutheleleka okukhulu okusabalalisa egazini.
Ngenhlanhla, akuvamile.
Njalo ngonyaka e-US, abantu banesifo se-East Coast ne-Gulf Coast. EFlorida ngo-2013, abangu-31 banesandulela ngculaza futhi abangu-11 bafa.
Ukuthola lesi sifo, nakuba singavamile, ngeshwa kuyilula. Ukuhamba okulula ebhishi, isinyathelo esikhwameni elibukhali, futhi amabhaktheriya emanzini afudumele olwandle afaka.
Amabhaktheriya atholakala ngokuvamile emanzini asolwandle afudumele. Amanzi afudumele akhulisa inani leVibrio Vulnificus elitholiwe. Itholakala kuphela emanzini anosawoti.
Iyiphi uhlobo lwesifo i-Vulnificus?
Ama-bacterium isihlobo sekholera. Bobabili bangela ukuhlanza nokuhuda. I-cholera isakazeka ngokushesha kusuka komuntu kuya komuntu obangela izifo eziwumshayabhuqe, kuyilapho kungekho bufakazi bokuthi u-Vulnificus usakazelele umuntu kumuntu. I-Vulnificus ingabangela ukutheleleka kesikhumba esinzima nesibindi. Futhi kungasakazeka egazini kulabo abasengozini kakhulu; lokhu kungasheshe kubulale.
Amaqiniso we-bacteria okudla inyama empeleni kuphela ama-Strep A izifo.
Ukutheleleka kwe-Vulnificus kubonakala sengathi ku-Strep kodwa kungabangeli ukutheleleka okusakazeka esikhumbeni ngokujulile njengoStrep.
Ziyini izimpawu?
- Uhudo, isisu, ubuhlungu besisu.
- Ukucindezelwa Kwegazi Eliphansi
- Isikhumba esiqhakazile nesibomvu eduze nalapho amabhaktheriya angena khona. Kukhona ukuphuma kwegazi okuhlobene nalezi zibhamu ezithokozayo.
Ngubani osemngciphekweni?
- Noma ubani odla ama-oyster aluhlaza noma amanye ama-shellfish.
- Noma ubani onenqamu evuliwe emanzini afudumele asolwandle, ikakhulukazi eGulf of Mexico, kodwa nakweminye imikhakha e-East Coast yase-US
Abaningi abasengozini
- Izifo zesibindi
- Amazinga aphezulu e-Iron
- Utshwala
- Izinkinga zesisu (kuhlanganise nokusetshenziswa kwe-Antacid)
Uthola kanjani igciwane?
Izifo zingenzeka kusukela ekuhambeni ogwini. Amabhaktheriya angangena amanxeba avulekile, afana nalawo angena emagobolondo abukhali noma ngilazi. Ikakhulukazi ehlotshaniswa nokusetshenziswa kotshwala. Ukutheleleka kungasakazeka kusukela esikhumbeni kuya egazini, kulabo abasengozini.
Ukutheleleka kungase kwenzeke ngokudla ama-oysters aluhlaza noma angaphuphuki okuvela eGulf Coast. Ingatholakala futhi emanzini ase-Atlantic nasePacific. Ukutheleleka kungasakazeka emathunjini abe ngegazi, kulabo abasengozini.
Iyini ingozi?
Ama-bacterium ngokuvamile adala izifo ezinzima - ukuxhaphazwa noma ukutheleleka egazini - kulabo abasengozini enkulu. Ingozi yokufa kulabo abahlakulela i-sepsis enamandla ingaba ngaphezu kwama-50%.
Indlela yokuphathwa ngayo
Ukwelashwa kwamacala amakhulu kudinga ukunakekelwa esibhedlela. Ngokuvamile i-ceftazidime ye-antibiotic ye-IV kanye ne-doxycycline yama-antibiotic. Ngezinye izikhathi kungaphathwa nge-fluoroquinolones. Ukutheleleka kwesikhumba kungaba nzima kakhulu kangangokuthi ukuhlinzwa kuyadingeka ukuyiqeda noma ngisho nokuxoshwa kungadingeka.
Kutholakala kanjani
Amabhaktheriya angatholakala esitokisini, enxebeni, noma emasikweni egazi, kodwa kudinga ukuba ama-lab abe nomphakathi okhethekile - noma ipuleti - ukuze amabhaktheriya akhule futhi abonakale.
Yini eyenziwa ukuyivimbela?
Ngisho nama-oysters avunwa ngokomthetho angaba ne-Vibrio Vulnificus. I-FDA isebenza nezikhulu zikahulumeni ukulandelela noma yikuphi ukutheleleka emibhedeni yama-oyster. Umsebenzi wenziwa ukuze kubonakale kangcono ukuthi yiziphi izinto eziholela ekukhuleni futhi kuncishiswe ingozi ukuthi labo oyster abavunwa baphathe amabhaktheriya.
