Integrons and gene cassettes in clinical isolates of co-trimoxazole-resistant Gram-negative bacteria.
The study identified a new dfr gene, dfrA22, in a class 1 integron, which contributes to trimethoprim resistance in co-trimoxazole-resistant Gram-negative bacteria.

Antimicrobial Resistance in Bacteria: Mechanisms and Current Challenges
This paper characterizes several beta-lactamases, including TEM-1, SHV-1, CTX-M-15, and NDM-1, which confer resistance to various beta-lactam antibiotics. It also identifies erm(B) and mef(A) as mechanisms of macrolide, lincosamide, and streptogramin B resistance. Additionally, aadA1 and aac(6')-Ib are noted for aminoglycoside resistance, while catA1 and floR contribute to chloramphenicol resistance. The vanA gene is associated with glycopeptide resistance, and mcr-1 is linked to polymyxin resistance.
Molecular characterization of extended spectrum cephalosporin resistant Escherichia coli isolated from livestock and in-contact humans in Southeast Nigeria.
The study identified four variants of bla CTX-M (CTX-M-15, CTX-M-55, CTX-M-64, and CTX-M-65) in extended-spectrum cephalosporin-resistant Escherichia coli from livestock and in-contact humans in Southeast Nigeria. Other AMR genes such as bla TEM-1b, aac 3-IId, qnr S1, and sul 2 were also characterized.
