Kodi muli ndi chifuwa chomwe sichimatha masiku angapo, kapena zizindikiro za matenda a mkodzo zomwe zimakuvutitsani? Mwina mutapita kwa dokotala, adakulemberani mayeso otchedwa 'Gram Stain'. Dzinali lingamveke lachilendo pang'ono kwa inu. Koma kwenikweni iyi ndi mayeso ofunikira kwambiri komanso achangu omwe amagwiritsidwa ntchito kuzindikira matenda m'thupi lathu. Chifukwa chake, tiyeni tikambirane za izi mosavuta, mwanjira yomwe mungamvetse.
Kodi Gram Stain ndi chiyani kwenikweni?
Mwachidule, Gram stain ndi mayeso omwe amachitidwa mu labu. Amafufuza mabakiteriya m'thupi lanu komwe kuli matenda. Tangoganizirani kuti muli ndi bala lomwe likutuluka. Kenako chitsanzo chaching'ono kuchokera pabalalo chingatumizidwe kuti chikayesedwe.
Chimodzi mwa ubwino waukulu wa mayesowa ndichakuti zotsatira zake zimapezeka mwachangu. Izi zimathandiza dokotala kudziwa mwachangu ngati muli ndi kachilombo ka bakiteriya, ndipo ngati ndi choncho, mtundu wake. Izi zimathandiza dokotalayo kudziwa bwino mankhwala omwe angakupatseni.
Si mabakiteriya onse m'thupi mwathu omwe ndi oipa. Ena ndi mabakiteriya abwino omwe amatithandiza. Koma mitundu ina ya mabakiteriya imatibweretsera matenda ndi matenda. Kuyesa kwa Gram Stain kumatithandiza kuzindikira mabakiteriya oopsa omwe amayambitsa matenda amenewo.
Kodi nkhaniyi yokhudza Gram-positive ndi Gram-negative ndi yotani?
Iyi ndi gawo lofunika kwambiri pa mayeso a Gram stain. Ganizirani za mabakiteriya ngati tizilombo ting'onoting'ono tovala zovala zosiyanasiyana. Mayeso a Gram stain amaphatikizapo kugwiritsa ntchito mitundu ingapo ya mabala apadera pa mabakiteriya. Kenako, kutengera kusiyana kwa khoma la selo la mabakiteriya, amapatukana m'mitundu iwiri.
1. Mabakiteriya okhala ndi gramu: Makoma a maselo awo amapangidwa ndi chinthu chokhuthala chotchedwa ``Peptidoglycan.'' Ichi ndichifukwa chake amasanduka mtundu wofiirira ndi wabuluu akapaka utoto.
2. Mabakiteriya opanda gramu: Awa ali ndi makoma opyapyala a maselo, kotero amasanduka mtundu wofiira ngati pinki akapaka utoto.
Chofunika kukumbukira apa ndichakuti 'zabwino' ndi 'zoipa' sizitanthauza 'zabwino' ndi 'zoipa'. Ndi gulu lokhalo lozikidwa pa mtundu wa mabakiteriya.
Tsopano tiyeni tiwone mitundu ikuluikulu ya mabakiteriya omwe ali m'magulu awiriwa ndi matenda omwe amayambitsa.
| Mabakiteriya a Gram-positive ndi matenda ena ofanana nawo | |
|---|---|
| Mtundu wa mabakiteriya | Matenda omwe angakhalepo |
| Mitundu ya Staphylococcus | Matenda a pakhungu, chibayo, poizoni wa chakudya, matenda a MRSA |
| Mitundu ya Streptococcus | Matenda a pakhosi (Strep throat), chibayo, meningitis |
| Mitundu ya Listeria | Kuopsa kwa chakudya |
| Mitundu ya Clostridium | Kupha poizoni m'chakudya, botulism, tetanasi |
| Mabakiteriya opanda gramu ndi matenda ena ofanana nawo | |
|---|---|
| Mtundu wa mabakiteriya | Matenda omwe angakhalepo |
| Escherichia coli (E. coli) | Matenda a mkodzo (UTIs), poizoni wa chakudya |
| Neisseria gonorrhoeae | Chinzonono (matenda opatsirana pogonana) |
| Mitundu ya Salmonella | Kuopsa kwa chakudya, malungo a typhoid |
| Mitundu ya Klebsiella | Chibayo, matenda a m'magazi, matenda a mabala |
Kodi kusiyana pakati pa Gram stain ndi bacterial culture ndi kotani?
Dokotala wanu nthawi zambiri angakulangizeni kuti muyese mayeso onse awiriwa pamodzi, koma zomwe amapereka ndi zosiyana.
- Gram Stain: Ichi chili ngati chithunzi cha nthawi yomweyo. Chimapereka mwachangu lingaliro la ngati mabakiteriya alipo, ngati alipo, ngati ali ndi Gram-positive kapena Gram-negative, komanso mawonekedwe awo (ozungulira kapena ofanana ndi ndodo).
- Kukula kwa Mabakiteriya: Izi zimaphatikizapo kukulitsa mabakiteriya omwe ali mu chitsanzo chanu mu chipangizo chapadera mu labu. Zili ngati kukulitsa chomera. Izi zingatenge masiku angapo. Mabakiteriya akakula bwino, mutha kuwazindikira ndikupeza maantibayotiki omwe amagwira ntchito bwino kwa iwo.
Mwachidule, Gram stain imapereka chitsogozo chachidule, pomwe chikhalidwe cha mabakiteriya chimapereka chitsimikizo chotsimikizika kwambiri .
Kodi mayeso a Gram Stain amachitidwa bwanji?
Njirayi ingagawidwe m'magawo atatu akuluakulu.
1. Kusonkhanitsa chitsanzo
Njira yotengera chitsanzocho imasiyana malinga ndi komwe mukuganiza kuti muli ndi kachilomboka.
- Ndi swab: Chitsanzo chingatengedwe kuchokera ku malo monga pakhosi, mphuno, zilonda za pakhungu, ndi malo oberekera pogwiritsa ntchito thonje.
- Kusonkhanitsa zinthu zotulutsa madzi m'thupi: Mukhoza kusonkhanitsa zinthu monga mamina, mkodzo, ndi ndowe m'chidebe choyera.
- Kutulutsa singano pang'ono: Njira iyi imagwiritsidwa ntchito pochotsa madzi m'thupi, mwachitsanzo, m'mafupa, m'mapapo, kapena m'mtima.
2. Chimachitika ndi chiyani mu labu
Chitsanzo chanu chikafika ku labu, wasayansi wa labotale ya zamankhwala adzachiyika pang'ono pa galasi loonera. Kenako, adzawonjezera utoto wapadera anayi, womwe takambirana kale, ndikuutsuka.
3. Kuyang'ana kudzera mu maikulosikopu
Pomaliza, slide yokonzedwayi imayesedwa pansi pa maikulosikopu. Apa ndi pamene timaona ngati mabakiteriya alipo, mtundu wawo (wofiirira/wabuluu kapena pinki/wofiira), mawonekedwe awo (ozungulira (cocci) kapena ooneka ngati ndodo (bacilli)), ndi momwe amagwirizanirana pamodzi (okha, awiriawiri, kapena m'magulu).
Kodi lipoti la kafukufuku likuti chiyani?
Pakhoza kukhala zotsatira ziwiri zazikulu mu lipoti lanu la mayeso.
- Dothi loipa la Gram (Palibe chamoyo chomwe chawoneka): Izi zikutanthauza kuti palibe mabakiteriya omwe adawoneka pa slide. Komabe, nthawi zina izi zitha kuchitika pamene pali mabakiteriya ochepa kwambiri. Chifukwa chake mungafunike kudikira lipoti la kukula kwa mbewu.
- Dothi labwino la Gram: Izi zikutanthauza kuti mabakiteriya analipo mu chitsanzo chanu. Lipotilo likhoza kuphatikizapo tsatanetsatane monga:
- Mtundu wa mabakiteriya: Gram-positive kapena Gram-negative?
- Mawonekedwe a mabakiteriya: `cocci` (wozungulira) kapena `bacilli` (ndodo)?
- Maselo ena: Zingadziwikenso ngati maselo ena alipo, monga maselo oyera a magazi (chizindikiro cha matenda).
Mwa kusonkhanitsa zonsezi ndikuziyerekeza ndi zizindikiro zanu, dokotala adzayamba chithandizo chabwino kwambiri kwa inu.
Uthenga Wopita Nawo Kunyumba
- Gram Stain ndi njira yofulumira komanso yosavuta yoyesera matenda a bakiteriya.
- Izi zimagawa mabakiteriya m'magulu awiri akuluakulu (Gram-positive - wofiirira/wabuluu ndi Gram-negative - pinki/wofiira).
- Izi zithandiza kwambiri dokotala wanu kuyamba kulandira chithandizo choyenera mwamsanga .
- Kuti mudziwe bwino matendawa, nthawi zambiri kuyezetsa kwa Gram stain kumachitika limodzi ndi kuyezetsa kwa bakiteriya .
- Ngati muli ndi nkhawa iliyonse yokhudza zotsatira za mayeso anu, musaope kukambirana momasuka ndi dokotala wanu .
