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 yesondlo, umzekelo, iqulethe umxube wezondlo, kuquka i-carbohydrates, iiprotheni, kunye nezinye izinto ezibalulekileyo ezifunekayo ekukhuleni kwe-microbial.Izazinzulu zisebenzisa izitya ze-petri ngeenjongo ezahlukeneyo, ezibandakanya: Ukulima ii-microorganisms: izitya zePetri zivumela izazinzulu ukuba zikhule kwaye zikhule ezahlukeneyo. i-microorganisms, enokuthi ibonwe ngabanye okanye ifundwe ngokudibeneyo.I-Isolating microorganisms: Ngokubetha isampuli kwisitya se-petri, iikholoni zomntu ngamnye ze-microorganisms ziyakwazi ukubekwa zodwa kwaye zifundwe ngokwahlukileyo.Ukuvavanya ukuchaphazeleka kwe-antibiotic: Ngokusetyenziswa kweediski ezifakwe kwi-antibiotic-impregnated, izazinzulu zinokumisela ukusebenza kwe-antibiotics ngokuchasene ne-microorganisms ethile ngokuqwalasela imimandla yokuthintela ejikeleze iidiski.Uhlolo lwendalo: izitya zePetri zingasetyenziselwa ukuqokelela iisampulu zomoya okanye ezingaphezulu ukufumanisa ubukho be-microorganisms kwindawo ethile.Izitya zePetri sisixhobo esisisiseko kwi-microbiology. iilebhu, ukunceda kuphando, ukuxilongwa, kunye nophononongo lwee-microorganisms.
