Ishishini lokutya kwemfuyo lisoloko lichatshazelwa "ngubhubhane ophindwe kabini" we-African swine fever kunye ne-COVID-19, kwaye likwajongene nomceli mngeni "ophindwe kabini" wokunyuka kwamaxabiso amaninzi kunye nokuthintelwa okubanzi. Nangona indlela engaphambili igcwele ubunzima, ishishini lokufuya izilwanyana likwakhuthaza ngenkuthalo utshintsho lwalo kunye nokuphucula kwaye likhuthaza uphuhliso lweshishini ngokubambisana. Eli phepha lixoxa kakhulu ngendlela yokuphucula umsebenzi wee-enzymes zokugaya ukutya emathunjini enkukhu, ukukhuthaza uphuhliso lwamathumbu kunye nokuphucula ulwakhiwo lwezityalo zamathumbu.

Umgudu wamathumbu sisitho esibalulekileyo kwinkukhu ukuze ikwazi ukugaya nokufunxa izondlo. Ukugaya amathumbu kwenziwa ikakhulu ngee-enzyme reactions (exopeptidase, oligosaccharide enzyme, lipase, njl.njl.); Izondlo ezincinci zemolekyuli eziveliswa yi-enzyme reaction zidlula kwi-intestinal epithelial layer kwaye zifunxwe ziiseli zamathumbu.

Amathumbu akwangumqobo wendalo wokukhusela iinkukhu kwi-antigens zokutya, iintsholongwane ezibangela izifo kunye ne-metabolites yazo eyingozi, kwaye agcine uzinzo lwendalo yangaphakathi. Umqobo wamathumbu uquka umqobo womatshini, umqobo weekhemikhali, umqobo weentsholongwane kunye nomqobo wokuzikhusela ukuze kukhuselwe ngokudibeneyo ekuhlaselweni kwezinto zangaphandle ze-antigen. Umqobo womatshini (umqobo womzimba) ubhekisa kwiiseli ze-epithelial zamathumbu ezidibeneyo ngokusondeleyo; Umqobo weekhemikhali wenziwe yi-mucus, ijusi yokugaya ekhutshwa ziiseli ze-epithelial zamathumbu kunye nezinto ezilwa neentsholongwane eziveliswa yintsholongwane ye-parasitic yamathumbu, enokuthintela okanye ibulale iintsholongwane ezibangela izifo; Umqobo webhayoloji wenziwe kukuxhathisa ukoloni lwezityalo ezihlala emathunjini kwiintsholongwane ezibangela izifo kunye nokuqokelelana phakathi kweentsholongwane; Umqobo wokuzikhusela lolona lungu likhulu le-lymphoid kunye nezicubu ezibalulekileyo ze-lymphoid ezinxulumene ne-mucosa. Ke ngoko, ukuzalisa kukuphakamisa indlela yamathumbu, kwaye ukuqinisekisa impilo yamathumbu ngundoqo ekuzaleni okunempilo ngaphandle kokuxhathisa.

I-asidi inefuthe le-acidification kunye ne-bacteriostasis, kwaye idlala indima ebalulekileyo ekuzaleni iinkukhu ezisempilweni. Ii-asidi ze-organic eziqhelekileyo ziquka ii-asidi ze-carboxylic ezilula (i-asidi ye-formic, i-acetic acid, i-propionic acid kunye ne-butyric acid), ii-asidi ze-carboxylic eziqulathe amaqela e-hydroxyl (i-asidi ye-lactic, i-asidi ye-malic, i-asidi ye-tartaric kunye ne-citric acid), ii-asidi ze-carboxylic ze-short chain eziqulathe ii-double bonds (i-asidi ye-fumaric kunye ne-sorbic acid) kunye nee-asidi ezingaphiliyo (i-asidi ye-phosphoric) (sh Khan kunye no-j Iqbal, 2016). Amandla e-acidification kunye ne-bacteriostatic ee-asidi ezahlukeneyo ahlukile, umzekelo, i-asidi ye-formic inamandla e-bacteriostatic anamandla; Phakathi kwee-asidi ngobunzima beyunithi, i-asidi ye-formic inamandla okubonelela nge-hydrogen anamandla; i-asidi ye-Propionic kunye ne-asidi ye-formic zinefuthe elinamandla lokulwa nokubola. Ke ngoko, xa ukhetha i-asidi, kufuneka ilinganiswe ngokwesayensi ngokweempawu ze-asidi. Izifundo ezininzi zibonise ukuba ukongeza amalungiselelo e-asidi ekutyeni kunokuphucula nokukhuthaza uphuhliso lwamathumbu, kuphucule umsebenzi wee-enzymes zokugaya ukutya kwamathumbu, kuphucule ulwakhiwo lwezityalo zamathumbu, kwaye kuncede ekuzaleni okunempilo ngaphandle kokutya okuchasene neJapan.

Ukuqukumbela, ukulungiswa kwe-asidi kunexabiso elibalulekileyo ekuqinisekiseni impilo yamathumbu enkukhu. Xa kufakwa kwaye kukhethwa i-asidi, kufuneka kuqwalaselwe ukwakheka, ubungakanani, umxholo kunye nenkqubo yokulungiswa kwe-asidi ukuqinisekisa ukhuseleko, uzinzo kunye nexabiso leemveliso.
