(n = 6)
|NM||–||–Predominant by tetracycline, MLS, aminoglycoside, and β-lactam.|||
(n = 4)
|Yes||NS||–Predominant by tetracycline, followed by aminoglycoside.||[120, 121]|
(n = 178)
|Yes||NS||–Tetracycline, macrolide, β-lactam and aminoglycoside AMR made up the majority of ARGs.|||
(n = 12)
–Predominant by MDR, followed by aminoglycoside, and tetracycline.|
–Chlortetracycline at low or therapeutic doses did not alter the relative abundance of total ARGs and predominant ARG classes.
(n = 63)
–Predominant by tetracycline, followed by MLS, aminoglycoside, and β-lactam.|
–More abundant ARGs in the fecal samples collected in markets than farms.
(n = 15)
–Predominant by tetracycline.|
–Ampicillin led to the increase in the abundance of ARGs belonging to β-lactam and bacitracin, and decrease of those belonging to tetracycline.
–Increase in β-lactam, bacitracin-resistance, and MDR genes were more evident for oral than intramuscular administration of ampicillin.
(n = 10)
–Predominant by tetracycline, MLS, and cephalosporin resistant genes are the most abundant in two altitudes (730 m and 3300 m).|
–Differential abundant MLS, cephalosporin, and tetracycline between low and high altitudes.
