The sulfonamides were the first drugs with antituberculous effects. Their use was abandoned and basically forgotten with the advent of streptomycin and isoniazid combination treatment. There is a widespread belief, apparently based on testing a single isolate on questionable media, that Mycobacterium tuberculosis is resistant to trimethoprim-sulfamethoxazole (TMP-SMX). We saw a complex immunoco...

OBJECTIVE To determine if trimethoprim use for urinary tract infection (UTI) is associated with an increased risk of acute kidney injury, hyperkalaemia, or sudden death in the general population. DESIGN Cohort study. SETTING UK electronic primary care records from practices contributing to the Clinical Practice Research Datalink linked to the Hospital Episode Statistics database. PARTICIP...

In trimethoprim-inhibited RCStr strains of Escherichia coli, the expression of the RC control of stable RNA synthesis arose primarily from a decrease in the intracellular concentrations of glycine and methionine, and not from inhibition of the initiation ofnew protein chains. In non-supplemented cultures, experiments with rifampicin showed that the immediate response to the addition of trimetho...

An intermittent regimen of trimethoprim-sulfamethoxazole was tested in the corticosteroid-treated rat model to learn whether or not administration for 3 consecutive days a week would provide prophylaxis equal to continuous daily doses. Although all of the untreated control animals acquired Pneumocystis carinii pneumonia, none of the animals given either continuous or intermittent trimethoprim-s...

Bacterial infections may cause disease and death. Infants and children are often subject to bacterial infections. Antimicrobials kill bacteria protecting the infected patients andreducing the risk of morbidity and mortality caused by bacteria. The antibiotics may lose their antibacterial activity when they become resistant to a bacteria. The resistance to different antibiotics in a bacteria is ...
