Overview
Multidrug-resistant Shiga toxin-producing Escherichia coli 0118:H16 Latin America.
The study reports the first isolation of a multidrug-resistant STEC O118:H16 strain from cattle in Latin America, highlighting the presence of various AMR genes such as blaTEM1-like, aphA1, strA/B, sul2, and tet[A].
Pork contaminated with Salmonella enterica serovar 4,[5],12:i:-, an emerging health risk for humans.
The study identified the genes bla TEM1-like, sul2, strA-strB, and tet(B) as responsible for multidrug resistance to ampicillin, sulfamethoxazole, streptomycin, and tetracycline in Salmonella enterica serovar 4,[5],12:i:-.
Frequent combination of antimicrobial multiresistance and extraintestinal pathogenicity in Escherichia coli isolates from urban rats (Rattus norvegicus) in Berlin, Germany.
The study identified multidrug-resistant Escherichia coli strains in urban rats, including an ESBL-producing strain (IMT20717) carrying bla CTX-M-9, bla TEM-1-like, sul2, strA, strB, aac(6′)-Ib-cr, and aadA. These strains exhibited resistance to multiple antimicrobial classes, including beta-lactams, aminoglycosides, and fluoroquinolones.
Molecular characterization and in silico analysis of naturally occurring TEM beta-lactamase variants among pathogenic Enterobacteriaceae infecting Indian patients.
The study identified several TEM beta-lactamase variants, including bla TEM-1, bla TEM-1 like, bla TEM-116, bla TEM-169, bla TEM-190, and bla TEM-33, which contribute to third-generation cephalosporin resistance in Enterobacteriaceae isolates from Indian patients.
Analysis of antibiotic-induced drug resistance of Salmonella enteritidis and its biofilm formation mechanism.
The study identified several antibiotic resistance genes in Salmonella enteritidis, including sul2, sul3, blaTEM-1-like, tet(A), and tet(G). These genes contribute to resistance against sulfamethoxazole, ampicillin, cefoxitin, cefotaxime, cefoperazone, ceftriaxone, cefepime, and tetracycline.
