Isitya se-petri sisitya esinganzulwanga, esisilinda, esicacileyo, kwaye esiqhelekile singenazintsholongwane esisetyenziswa kwiilabhoratri zokulima iintsholongwane, ezifana neebhaktheriya, umngundo, okanye ezinye izinto ezincinci. Ithiywe ngegama lomqambi wayo, uJulius Richard Petri.Isitya sepetri siqhele ukwenziwa ngeglasi okanye iplastiki ecacileyo, kwaye isiciko saso sikhulu ngobubanzi kwaye sijike kancinane, sivumela ukupakishwa ngokulula kwezitya ezininzi. Isivalo sithintela ukungcoliseka ngelixa sisavumela ukuhamba komoya okwaneleyo.Izitya zePetri zizaliswe ngendawo yezondlo, ezifana ne-agar, enika indawo exhasayo yokukhula kwe-microorganisms. I-agar yezondlo, umzekelo, iqulethe umxube wezondlo, kubandakanywa i-carbohydrates, iiprotheni, kunye nezinye izinto eziyimfuneko ezifunekayo ekukhuleni kwe-microbial.Izazinzulu zisebenzisa izitya ze-petri ngeenjongo ezahlukeneyo, ezibandakanya: Ukulima i-microorganisms: izitya zePetri zivumela izazinzulu ukuba zikhule kwaye zikhule ii-microorganisms ezahlukahlukeneyo, ezinokubonwa ngabanye okanye zifundwe ngesampulu ye-microorganisms i-isolating kwi-microorganisms i-isolating a isolating. isitya, iikholoni zomntu ngamnye we-microorganisms ziyakwazi ukubekwa zodwa kwaye zifundwe ngokwahlukeneyo.Uvavanyo lwe-antibiotic susceptibility: Ngokusetyenziswa kwe-antibiotic-impregnated discs, izazinzulu zinokumisela ukusebenza kwe-antibiotics ngokuchasene ne-microorganisms ethile ngokuqwalasela imimandla yokuthintela ejikeleze iidiski.Ukubeka iliso kokusingqongileyo: Izitya zePetri zingasetyenziselwa ubukho bendawo ye-microorganism ubukho okanye iisampulu zomoya ukuze zikwazi ukuqokelela indawo yomoya. izitya zisisixhobo esisisiseko kwiilebhu ze-Microbiology, ukunceda kuphando, ukuxilongwa, kunye nokufundwa kwee-microorganisms.
