Batho ba ka holimo ho 40 ba tšoaelitsoe, ba 15 ba shoele, ba tšoaelitsoe ke baktheria eo re sa e tsebeng hakaalo - Elizabethkingia anophelis.
Bohle ba nang le tšoaetso ba bile batho ba baholo Wisconsin, boholo ba batho ba baholo. Ba bangata ba 'nile ba feta lilemo tse 65' me ba tlalehoa hore ba na le mathata a mang a bophelo bo botle. Ba bang ba ne ba le mahaeng a maqheku, ba bang ba lipetlele. Ha ho hlake hore na ho kula ho e-s'o ka ho e-ba teng le hore na tšoaetso ea baktheria e ngata hakae ho tlatsetsa lefung.
Ha e bonahale e le bothata ho ba nang le bophelo bo botle le ba ka ntle ho litsi tsa tlhokomelo. Li-epidemiologists le basebetsi ba laboraka - ba tsoang mmuso le CDC - ba leka ho bona hore na sena se etsahala joang.
Elisabethkingia anophelis Effects
Boloetse bona ba baktheria bo ka lebisa feberu, phefumoloho e khutšoanyane, likokoana-hloko le tšoaetso ea letlalo - cellulitis - e ka kenyang libaka tse bohloko le tse ling tse khubelu tsa letlalo. E fumanoe metseng ea mali ea bakuli 'me e entse setšoantšo sa kliniki ea sepsis.
Ka linako tse ling kahobane mokuli a kula hantle, ha ho hlaka hore na tšoaetso ea Elizabethkingia ke mokolosi-baktheria e fumanoang ntle le ho baka bokuli; ho motho ea seng a kula sepetlele, ho thata ho bolela hore na sena se na le bothata kapa se baka mathata. Haeba e se moholehuoa, bothata boo bo kenya letsoho hakae kapa bo hlile boa kula? Ho bonahala libaktheria tsena, le hoja li atisa ho bonoa e le koloneli libakeng tse ling, li baka tšenyo ea eona ts'ebetsong ena ho Wisconsin.
Libaktheria li etsa hore batho ba kula-kapa ba kula (e hlasela haholo-holo ba seng ba ntse ba kula).
Tsejoa
Liteko tsa laboratori tsa microbiology li hlokahala ho fumana hore na tšoaetso e bakoa ke Elizabethkingia anophelis.
Haeba libaktheria li fumanoa maling kapa mokelikeli o mong oa 'mele, sesebelisoa sa' mele oa metsi o ka sebelisoa ho hōlisa libaktheria ho laboratori.
Libaktheria li hōlileng ka lipoleiti tsa laboratori tse sa tšoaneng tse nang le mefuta e sa tšoaneng, ho bona moo libaktheria li hōlang le moo li sa khoneng ho hōla, hammoho le liteko tse ling, ka tsela eo ho khetholla libaktheria tse teng.
Bothata ke hore libaktheria tse seng kae li ka 'na tsa se ke tsa tsejoa habonolo. Ho khetholla hase kamehla hang-hang. Ho bonolo ho qala ho tseba hore na baktheria e na le gram kapa e ntle. Elisabethkingia anophelis ke gram. Bothata ke hore lithibela-mafu tse ngata tse sebetsang ka libaktheria tse ngata tsa grama ha li sebetse ho Elizabethkingia anophelis.
Tse ling tsa li-Bugs tse tšoanang
Ho na le mefuta e meng ea mofuta oa Elizabethkingia. Tsena li kenyelletsa Elizabethkingia meningoseptica ( e tloaelehileng haholo bathong ), Elizabethkingia miricola, le Elizabethkingia endophytica.
Tsena kaofela ke li-aerobic, nonmotile, li-gram-negative. Mabitso a libaktheria ha a ngoloe ka majoe. Hangata ba fetoha. Tse ling tsa mefuta ena e neng e tloaelehile ho ba karolo ea mofuta oa Flavobacterium .
Mefuta ena e batla e tšoana; Karolo ea 98,6 lekholong ea liphatsa tsa lefutso e tšoana le Elizabethkingia meningoseptica le 98.2 lekholong liphatsa tsa lefutso tse tšoanang le Elizabethkingia miricola.
Phekolo
Bothata ba Elizabethkingia ke baktheria ebile bo phekoloa ka lithibela-mafu. Bothata ke hangata libaktheria ha li arabele likokoana-hloko tse tloaelehileng.
Likokoana-hloko tse sebetsang khahlanong le eona li ka 'na tsa makatsa -' me qetellong lingaka li tla li finyella. Tlhahlobo ea pele ea libaktheria (e le gram-negative) e tla lebisa litsebi tsa bongaka hore li sebetsane hantle le lithethefatsi tse ka 'nang tsa se ke tsa sebetsa.
Bothata ba Elizabethkingia hangata bo hanyetsa likokoana-hloko tse ngata tseo ka tloaelo li tšoarang libaktheria tsa gram-negative - li-aminoglycosides, le lithethefatsi tsa β-lactam, ho akarelletsa le li-carbapenems. Libaktheria tsena li tsejoa ka ho etsa li-β-lactamases (ESBL) tse atolositsoeng le metallo-β-lactamases. Ka mantsoe a mang, libaktheria tsena li ka loantša lithibela-mafu tseo hangata li nahanoang, empa hangata ka phoso, e le "lithunya" tse kholo ka ho fetisisa khahlanong le libaktheria.
Leha ho le joalo, E. meningoseptica, e tšoanang le litlhaselo tsohle tsa Elizabethkingia ke gram-negative, ho bonahala ho arabela lithethefatsi tse ling tse sebelisetsoang libaktheria tse nang le gram. Ke hore, Elizabethbetia mafu a tšoaetsanoang a tsebahala ho arabela lithethefatsi tse kang Vancomycin, eo hangata e khonang ho tšoara mafu a gram-positive.
Ho na le phihlelo e fokolang ea ho phekola Elizabethkingia anophelis , empa pele ho hlaha hona, libaktheria li ile tsa bontšoa, ntle le ho tsejoa ha li-antibiotic li hlahella, ho hanyetsa ampicillin, chloramphenicol, kanamycin, streptomycin, le tetracycline.
Tabeng ena, libaktheria li bonahala li hlaseloa ke Bactrim (trimethoprim / sulfamethoxazole), fluoroquinolones (joaloka levofloxacin kapa ciprofloxacin, mohlomong), le Zosyn (piperacillin / tazoctam). Hangata phekolo ea motsoako e khothalletsoa - joalo ka ho khoneha ho phaella ha Vancomycin.
Litaba li lokela ho tlalehoa ho basebeletsi ba Bophelo ba Sechaba - le hore na ho na le linyeoe tse bakoang ke libaktheria tse tšoanang. Ka ho khetheha, mefuta e meng ea Elizabethkingia kapa likokoana-hloko tse amanang le tsona li lokela ho tlalehoa kaha li ka 'na tsa se tsejoe hantle.
