Aminoglycosides are antimicrobials that repress bacterial protein synthesis
[38]. Streptomycin is one of the primary aminoglycoside antibiotics presented in human medication. It is additionally utilized in animals and poultry.
Salmonella resistance to streptomycin has been documented in chicken in Bangladesh, ranging from 38% to 100%
[11][39][40][12][16]. Similarly, Souza et al.
[21] reported 98.30% resistance in
Salmonella to streptomycin from poultry in Brazil. Gentamicin, a broad-spectrum aminoglycoside antibiotic, has long been used to treat Gram-negative and Gram-positive microbes in poultry in Bangladesh. Extremely recently, Siddiky et al.
[16] reported 86.70% resistance in
Salmonella to gentamicin in the broilers, sonali, and indigenous chickens in Bangladesh. Previously, Wajid et al.
[19] observed 64.70% resistance to gentamicin from
S. Typhimurium isolates in poultry in Pakistan. Earlier, Hassan et al.
[35] and Paul et al.
[7] also observed significant amount of resistance to other aminoglycosides in
Salmonella such as kanamycin in the layers. Alam et al.
[12] reported the aminoglycoside-resistant gene
aadA1 (77.10%) in
Salmonella isolates from cloacal swabs and a litter of broilers in Mymensingh. Siddiky et al.
[16] observed the
strA/B (33.33%) resistance gene in
S. Typhimurium isolates from broilers ceca at wet markets in Dhaka. Earlier, Wajid et al.
[19] reported aminoglycosides
aadA1 (35.20%),
strA (20.50%) and
strB (41.10%) resistance genes, respectively, in
S. Typhimurium from poultry in Pakistan.
