O I-Staphylococcus epidermidis, noma S. epidermidis, yigciwane eline-gram-positive elikhona ngokwemvelo esikhumbeni, elingalimazi emzimbeni. Le microorganism ibhekwa njengosomathuba, njengoba ikwazi ukudala izifo lapho amasosha omzimba entekenteke, ngokwesibonelo.

Ngoba ngokwemvelo ikhona emzimbeni, i- I-Staphylococcus epidermidis akubhekwa kabanzi ekusebenzeni komtholampilo, ngoba isikhathi esiningi sihlukaniswe elebhu kusho ukungcoliswa kwesampula. Kodwa-ke, le microorganism iyakwazi ukukhula kalula kumadivayisi wezokwelapha, ngaphezu kokubikwa ukuthi ayizweli kuma-antibiotic ahlukahlukene, okwenza kube nzima ukwelapha ukutheleleka.

Indlela yokukhomba ukutheleleka nge S. epidermidis

Uhlobo oluyinhloko lokutheleleka nge S. epidermidis yi-sepsis, ehambelana nokutheleleka egazini, ngoba leli bhaktheriya lingena kalula emzimbeni, ikakhulukazi lapho amasosha omzimba ehlehlisiwe, ngaphezu kokuhlanganiswa ne-endocarditis. Ngakho, ukutheleleka nge S. epidermidis kungabonakala ngokuhlaziywa kwezimpawu, okuyizona eziyinhloko:

• Umkhuhlane omkhulu;
• Ukukhathala ngokweqile;
• Ikhanda;
• Ukugula okuvamile;
• Ukwehla komfutho wegazi;
• Ukuphefumula kanzima noma ukuphefumula kanzima.

O S. epidermidis imvamisa ihlotshaniswa nokutheleleka endaweni yesibhedlela ngenxa yekhono layo lokufaka ikholoni kumadivayisi we-intravascular, amanxeba amakhulu kanye nokufakelwa, ngokwesibonelo, ukuphatha ukwanda nokumelana nokwelashwa.

Ukuxilongwa kwenziwa kanjani

Endaweni yokucwaninga, ukuhlonza leli bhaktheriya kwenziwa ngokuhlolwa, okuyinhloko okuyi-coagulase test, ehlukanisa S. epidermidis ye I-Staphylococcus aureus. O S. epidermidis ayinayo le enzyme, ngakho-ke, kuthiwa i-coagulase negative, futhi ibhekwa njenge-coagulase negative staphylococcus ebaluleke kakhulu emtholampilo, ngoba ihlotshaniswa nokungcola okuyisampula, ukutheleleka kosomathuba kanye nekoloni lamadivayisi ezokwelapha.

Ukukuhlukanisa nezinye izinhlobo ze-coagulase-negative staphylococci, ukuhlolwa kwe-novobiocin kuvame ukwenziwa, okwenziwa ngenhloso yokubheka ukumelana noma ukuzwela kwaleli antibiotic. O S. epidermidis imvamisa iyazwela kule antibiotic, futhi imvamisa iyindlela yokwelashwa ekhonjiswa ngudokotela. Kodwa-ke, kunezinhlobo ze- S. epidermidis esivele inendlela yokumelana nale antibiotic, eyenza ukwelashwa kube nzima.

Imvamisa ubukhona be S. epidermidis egazini akusho ukuthi ukutheleleka, ngoba njengoba kusesikhumbeni, ngesikhathi senqubo yokuqoqwa kwegazi, amagciwane angangena ekusakazeni, kubhekwe njengokungcola kwesampula ezimweni eziningi. Ngakho-ke, ukuxilongwa kokutheleleka nge S. epidermidis kwenziwa kusukela ekuhlaziyweni kwamasiko egazi amabili noma ngaphezulu, okuvame ukuqoqwa ezindaweni ezahlukahlukene ukugwema imiphumela engamanga.

Ngakho-ke, ukuxilongwa kokutheleleka nge S. epidermidis kuyaqinisekiswa lapho wonke amasiko egazi elungile kule-microorganism. Lapho kuphela isiko elilodwa legazi elifanele S. epidermidis kanti ezinye zivumelana nenye i-microorganism, kubhekwa njengokungcola.

Kuyini S. epidermidis ukumelana

Imvamisa ukungcoliswa kwesampula ngu S. epidermidis itolikwa kabi ngamalabhorethri futhi ikhonjiswe njengokutheleleka emphumeleni wokuhlolwa, okwenza udokotela akhombise ukusetshenziswa kwama-antibiotic alwa "nokutheleleka". Ukusetshenziswa okungafanele kwama-antibiotic kungavumela ukwakheka kwamagciwane amelana nawo, okwenza kube nzima ukwelashwa.

Njengamanje, ukutheleleka ngu S. epidermidis bebehlala njalo ezigulini ezibhedlela futhi, ngakho-ke, bathole ukubaluleka komtholampilo hhayi kuphela ngenxa yokusebenzisa ngokungakhethi ama-antibiotic, kodwa futhi namandla abo okwenza i-biofilm kwimishini yezokwelapha, ethanda ukwanda kwaleli bhaktheriya nokumelana nokwelashwa.

Yelashwa kanjani

Ukwelashwa kokutheleleka nge I-Staphylococcus epidermidis kuvame ukwenziwa ngokusetshenziswa kwama-antibiotic, noma kunjalo, i-antimicrobial of choice iyahlukahluka ngokuya ngezimpawu zamagciwane, ngoba amaningi anezindlela zokumelana nawo. Ngakho-ke, ukusetshenziswa kweVancomycin neRifampicin, ngokwesibonelo, kunganconywa ngudokotela.

Ngaphezu kwalokho, ukwelashwa kwe- S. epidermidis kukhonjiswa kuphela lapho ukutheleleka kuqinisekisiwe. Uma kwenzeka kusolwa ukungcoliswa kwesampula, kuqoqwa amasampula amasha ukubheka ukuthi ngabe bekukhona ukungcola noma ngabe kumele ukutheleleka.

Endabeni yokwenza amakoloni ama-catheters noma ama-prostheses ngu S. epidermidis, kuvame ukunconywa ukushintsha idivayisi yezokwelapha. Njengamanje, ezinye izibhedlela zisebenzisa ukusetshenziswa kwemishini yokuvikela ukubulala amagciwane evimbela ukwakheka kwe-biofilm kanye nokwakhiwa kwe- I-Staphylococcus epidermidis, ukuvimbela ukutheleleka.
