Kua pāngia tonutia te umanga whāngai kararehe e te "mate urutā takirua" o te kirika poaka Āwherika me te COVID-19, ā, kei te anga atu hoki ki te wero "takirua" o te pikinga utu maha me te aukati whānui. Ahakoa he uaua te huarahi kei mua, kei te kaha te umanga whakatipu kararehe ki te whakatairanga i tana ake huringa me te whakapai ake, me te whakatairanga tahi i te whanaketanga o te umanga. Ko te kaupapa matua o tēnei pepa ko te whakapai ake i te mahi a ngā whākōkī nakunaku i roto i te whekau manu, te whakatairanga i te whanaketanga o te whekau me te whakapai ake i te hanganga o ngā tipu whekau.

He okana nui te ara whekau mō te manu hei nakunaku me te mimiti i ngā matūkai. Ko te nakunaku o te whekau ka mahia mā roto i ngā tauhohenga whākōkī (exopeptidase, oligosaccharide whākōkī, lipase, me ētahi atu); ko ngā matūkai ngota iti i hangaia e te tauhohenga whākōkī ka haere mā roto i te paparanga epithelial whekau ka mimitihia e ngā pūtau whekau.

He ārai taiao anō hoki te whekau hei tiaki i ngā manu mai i ngā antigens kai, ngā moroiti mate me ō rātou matū kino, me te pupuri i te pumau o te taiao o roto. Ko te ārai whekau he ārai ā-ringa, he ārai matū, he ārai moroiti me te ārai ārai mate hei tiaki tahi i te whakaekenga mai o ngā matū antigenic tauhou. Ko te ārai ā-ringa (ārai tinana) e pā ana ki ngā pūtau epithelial whekau katoa e hono tata ana tetahi ki tetahi; Ko te ārai matū he mea tito mai i te hūpē, te wai nakunaku i hunaia e ngā pūtau epithelial mucosal whekau me ngā matū antibacterial i hangaia e ngā huakita pirinoa whekau, ka taea te aukati, te patu rānei i ngā moroiti mate; Ko te ārai koiora he mea tito mai i te ātete koroni o ngā tipu noho whekau ki ngā huakita mate me te kohikohinga i waenga i ngā huakita; Ko te ārai ārai mate te okana lymphoid nui rawa atu me te kiko lymphoid nui e pā ana ki te mucosa. Nō reira, ko te whakatipuranga he whakaara ake i te ara whekau, ā, ko te whakarite i te hauora o te whekau te kī ki te whakatipuranga hauora me te kore ātete.

He pānga waikawa te waikawa me te bacteriostasis, ā, he mahi nui tāna ki te whakatipu heihei hauora. Ko ngā waikawa waro noa ko ngā waikawa carboxylic māmā (waikawa formic, waikawa acetic, waikawa propionic me te waikawa butyric), ngā waikawa carboxylic kei roto ngā rōpū hydroxyl (waikawa lactic, waikawa malic, waikawa tartaric me te waikawa citric), ngā waikawa carboxylic mekameka poto kei roto ngā hononga takirua (waikawa fumaric me te waikawa sorbic) me ngā waikawa inorganic (waikawa phosphoric) (sh Khan me j Iqbal, 2016). He rerekē te kaha waikawa me te kaha bacteriostatic o ngā waikawa rerekē, hei tauira, ko te waikawa formic te kaha bacteriostatic kaha rawa atu; I roto i ngā waikawa mō ia taumaha, ko te waikawa formic te kaha tuku hauwai kaha rawa atu; he kaha te pānga ārai harore o te waikawa propionic me te waikawa formic. Nō reira, i te wā e whiriwhiri ana i te waikawa, me whakatauritehia kia rite ki ngā āhuatanga o te waikawa. He maha ngā rangahau kua whakaatu ko te tāpiri i ngā whakaritenga waikawa ki te kai ka taea te whakapai ake me te whakatairanga i te whanaketanga o te puku, te whakapai ake i te mahi a ngā whākōkī nakunaku puku, te whakapai ake i te hanganga o ngā tipu puku, me te āwhina i te whakatipu hauora me te kore kai Hapanihi.

Hei whakamutunga, he mea nui te whakarite waikawa hei whakarite i te hauora o te puku o te manu. I te wā e whakamahia ana, e tīpakohia ana hoki te waikawa, me aro nui ki te hanganga, te ōwehenga, te ihirangi me te tukanga o te whakarite waikawa kia mau ai te haumaru, te pumau me te uara o ngā hua.
