Kwihanganira ubushyuhe no kwihagarika burundu indwara ziterwa n'udukoko dusanzwe mu miterere y'uturemangingo
Udukoko dusanzwe twanduza imiterere y'uturemangingo turimoEscherichia coli, Staphylococcus aureus, umusemburo, ibihumyo, mycoplasma na virusi. Ni mu bihe bihe utu dukoko dushobora guhagarara?
1) Escherichia coli
E. coliIfite ubushyuhe buke. Kwinika mu mazi ashyushye kuri 60°C mu gihe cy'iminota 30 bituma isuku ikomeza; gushyushya kuri 70°C mu gihe cy'iminota 3 byica bagiteri; amazi abira kuri 100°C atuma idakora mu gihe cy'iminota 1 kugeza kuri 3.
2) Staphylococcus aureus
Uturemangingo tw’ibimera tudafite sporesS. aureusIfite ubushobozi bwo kwihanganira ubushyuhe buri ku rugero kandi ntishobora kwihanganira ubushyuhe bwinshi. Kwiyuhagira mu mazi kuri dogere selisiyusi 60 mu gihe cy'iminota 30 bikuraho bagiteri nyinshi zikomeye; kuyivura kuri dogere selisiyusi 70 mu gihe cy'iminota 10 bituma uturemangingo tw'ibimera tudakora.
3) Umusemburo
Uturemangingo tw’umusemburo muri rusange tureka gukura hejuru ya dogere selisiyusi 47. Ubushyuhe bwiza bwo gukura bwazo buri hagati ya dogere selisiyusi 20 na dogere selisiyusi 30, naho ubushyuhe bwiza bwo gushyushya ni dogere selisiyusi 40–42. Uturemangingo tw’umusemburo twicwa mu minota mike kuri dogere selisiyusi 55–56.
4) Ibihumyo
Ibihumyo biramba kandi bikororoka mu mwijima kandi ahantu hashyushye kuri 20–30°C. Gushyushya ibihumyo byinshi kuri 80°C no kubibika mu gihe cy'iminota 20 bituma bikurwamo imiti. Ariko, ibihumyo (propagules) birwanya ubushyuhe bwinshi kandi biragoye kubikuraho ukoresheje amazi abira kuri 100°C; kuvura ubushyuhe bwinshi kuri 121°C mu gihe cy'iminota 10 bishobora gutuma ibihumyo bihagarara.
5) Mycoplasma
Mycoplasma ni bagiteri zoroshye zitagira inkuta z'uturemangingo kandi zizwi nk'utunyabuzima duto cyane twiyongeranya (ubusanzwe tuba turi hagati ya 0.1–0.3 μm mu murambararo). Ubushyuhe bwiza bwo gukura kwazo ni 35°C, kandi ntizikunda ubushyuhe cyane. Guhura na 100°C mu gihe cy'iminota 5 byica burundu mycoplasma.
6) Virusi
Muri rusange virusi zishobora kwibasirwa n'ubushyuhe. Virusi nyinshi zihagarara nyuma y'iminota 30 kuri dogere selisiyusi 55–60, kandi amasegonda make gusa yo kubira kuri dogere selisiyusi 100 arahagije kugira ngo zihagarike burundu.
