Cov khoom no muaj zog inhibitory cuam tshuam rau feem ntau cov kab mob gram-zoo thiab tsis zoo. Cov kab mob rhiab heev rau cov tshuaj sulfonamide tsis tuaj yeem siv cov tshuaj folic acid hauv ib puag ncig ib puag ncig, tsuas yog tuaj yeem siv p-aminobenzoic acid thiab dihydropteridine, nyob rau hauv qhov kev txiav txim ntawm cov kab mob dihydrofolate synthase los ua ke tetrahydrofolate, activated tetrahydrofolate nyob rau hauv lub synthesis ntawm purine, thymine nucleoside plays ib tug tseem ceeb luag hauj lwm ntawm cov pa roj carbon dioxide. Cov tshuaj sulfa zoo ib yam li cov qauv rau p-aminobenzoic acid, thiab tuaj yeem sib tw nrog p-aminobenzoic acid rau dihydrofolate synthetase hauv cov kab mob, cuam tshuam cov synthesis ntawm dihydrofolate, thaum kawg cuam tshuam rau synthesis ntawm nucleic acid, thiab inhibit qhov kev loj hlob thiab kev loj hlob ntawm cov kab mob. Kev txiav txim ntawm sulfanilamide tshuaj tuaj yeem tiv thaiv los ntawm cov tshuaj uas tuaj yeem ua rau cov amino benzoic acid, xws li procaine thiab tetracaine. Tsis tas li ntawd, cov kua paug thiab cov ntaub so ntswg puas tuaj yeem muab cov khoom tseem ceeb rau kev loj hlob ntawm cov kab mob, thiab muaj kev cuam tshuam rau sulfonamides. Trimethoprim yog ib qho tshuaj tiv thaiv kab mob sib koom ua ke uas inhibits kev ua haujlwm ntawm dihydrofolate reductase. Kev sib xyaw ua ke ntawm ob tuaj yeem tsim cov nyhuv synergistic los txhim kho cov nyhuv antibacterial.
Sulfonamides tshuaj tua kab mob, feem ntau cov kab mob gram-zoo thiab cov kab mob tsis zoo muaj zog inhibition nyhuv, siv nyob rau hauv cov tsiaj nyeg thiab nqaij qaib escherichia coli thiab pasteurella kab mob. Nws kuj tseem siv tau rau swine toxoplasmosis, nqaij qaib thiab luav coccidiosis.
Los ntawm cov khoom no. Rau kev tswj hwm sab hauv: koob tshuaj txhua hnub, ib 1kg lub cev hnyav, 32mg rau npua thiab qaib; rau npua, rau 5 mus rau 10 hnub; thiab nqaij qaib, rau 3 mus rau 6 hnub. Kev sib xyaw pub mis: Cov khoom no 100g sib tov 500 ~ 750kg, nruam siv npua 5 ~ 10 hnub, tsis tu ncua siv nqaij qaib 3 ~ 6 hnub. Mixed haus: 100g ntawm cov khoom no tov nrog dej 1000- 1500kg, siv rau 5 ~ 10 hnub rau npua, 3 ~ 6 hnub rau qaib.
