Two Escherichia coli isolates resistant to trimethoprim but negative for integrons carried two new resistance genes, dfrA24 and dfrA26, remotely similar to one another and to the cassette-independent genes dfrA8 and dfrA9. The dfrA24 gene was not associated with known

Protein concentrations are often regulated by dynamic changes in translation rates. Nevertheless, it has been challenging to directly monitor changes in translation in living cells. We have developed a reporter system to measure real-time changes of translation rates in human

Sulfonamides and trimethoprim have been used for many decades as efficient and inexpensive antibacterial agents for animals and man. Resistance to both has, however, spread extensively and rapidly. This is mainly due to the horizontal spread of resistance genes, expressing
