AGLV324 STREPTOCOCCUS

Algetec

Mayelana nalolu hlelo lokusebenza

1. INHLOSO
Lokhu kuhlolwa kunikeza ulwazi lwezimpawu ezijwayelekile zohlobo lwe-Streptococcus ngokuhlukaniswa kwezinhlobo zaleli qembu. Ukwengeza, ukuhlolwa kuthuthukisa ikhono lokubona amagciwane ohlobo lwe-Streptococcus ahlukaniswe amasampula ezinto eziphilayo elabhorethri yomtholampilo, kusukela ekuboneni ngeso lengqondo ikoloni kusiko lokuqala kuya ekuhlonzeni i-microorganism. Njengengxenye yemisebenzi, kuzodingeka ufunde ngokusebenza kokuhlolwa kwamakhemikhali ezinto eziphilayo asetshenziswa ohlelweni lwelabhorethri yomtholampilo, ngaphezu nokufunda indlela yokubika umphumela nokuxazulula izinguquko ezingaba khona ekuhlolweni kwamakhemikhali e-biochemical.


Ekupheleni kwalokhu kuhlolwa, kufanele ukwazi uku:

Khomba i-Streptococcus spp nge-morphologically macro.

enze ukuhlolwa okuhlukile kwezinye i-Gram positive cocci;

yenza ukuhlolwa okuhlukile kwezinhlobo ezahlukene.

2. Isetshenziswa kuphi le miqondo?
Ukwazi ukuthi ungawabona kanjani amagciwane ohlobo lwe-Streptococcus kuyimfuneko yokuthuthukisa amakhono okuhlola namakhono avumela ukuxilonga izifo ezibangelwa yilawa magciwane. Ngaphezu kwalokho, ukuhlonza okulungile kwenza ukwelashwa okusheshayo nokufanelekile kubantu abathintekile.


3. Ukuhlolwa
Kulolu cwaningo, i-Streptococcus spp izokhonjwa ngokwe-morphologically macro and microscopically. Kulokhu, okokufaka okuhlukahlukene kuzosetshenziswa, okufana nalokhu: ikhithi yokubulala amagciwane e-countertop (utshwala ne-hypochlorite), ikhithi yedayi ye-Gram (i-crystal violet, i-lugol, i-ethyl alcohol, i-fuchsin noma i-Safranine), isixazululo se-physiological (saline 0, 9%), uwoyela wokucwiliswa. , 3% i-hydrogen peroxide, ama-bacitracin discs, ama-trimethoprim-sulfamethoxazole discs, ama-optochin disc, ukuhlolwa kwe-PYR, umhluzi we-hyperchlorinated, Ukuhlolwa kwekamu, i-bile esculin, ukuhlolwa kwe-bile solubility, i-agar yegazi engu-5% yezimvu equkethe izinhlobo ze-Streptococcus α, β, δ i-hemolytics namathuluzi azosiza ekwenzeni lo mkhuba, njengamaslayidi, i-Pasteur pipette (uma ibhodlela likadayi lingenaso isikhiphi), ipensela yezibalo zabantu, isibani nesibonakhulu .


4. Ezokuphepha
Kulo mkhuba, amagilavu, imaski kanye nejazi, okubizwa nangokuthi i-dust jacket, izosetshenziswa. Nakuba umkhuba ungabangeli ingozi kumfundi, le mishini emithathu yokuzivikela ibalulekile endaweni yaselabhorethri. Igilavu ​​izovimbela noma yikuphi ukusikeka okungaba khona noma ukungcoliswa ngama-ejenti ayingozi esikhumbeni, imaski ivikela kuma-aerosol okungenzeka futhi ijazi lelebhu livikela umzimba wonke.


5. Isimo
Indawo yokuhlola ifaka isishisi se-Bunsen esibekwe ebhentshini lokusebenza, kanye nezinto ezisetshenziswayo namathuluzi. Kufanele uzikhethe futhi uzisebenzise ukuze uqinisekise ukwenziwa kahle kokuhlolwa.
