a sensitive high performance liquid chromathography (hplc) analytical procedure was developed for the quantitive determination of trimethoprim (tm* and sulphamethoxazole (sm) in commercial dosage forms. c18 analytical column (stainless steel, 25 cm * 4.6 mm i.d.) was packed with 5-*m particles of the reversed phase material and used for assays. mobile phase containing 0.025 m sodium phosphate a...

Antimicrobial susceptibility test results for trimethoprim-sulfadiazine with Streptococcus equi subspecies are interpreted based on human data for trimethoprim-sulfamethoxazole. The veterinary-specific data generated in this study support a single breakpoint for testing trimethoprim-sulfamethoxazole and/or trimethoprim-sulfadiazine with S. equi This study indicates trimethoprim-sulfamethoxazole...

infectious agents cause disease in virtually any susceptible hosts. in the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antibiotics into hatching eggs. there is little information available describing the safety of the folate antimetabolite/sulfonamide class of antibiotics on the game birds embryonated eggs. the objective of this study was ...

Urine samples with trimethoprim-resistant or trimethoprim-sensitive Gram-negative bacteria and samples with no bacterial growth (NG) were identified. Age-sex matched community controls were generated with each trimethoprim-resistant case. These four groups were evaluated for exposure. Prior trimethoprim use was significantly more common in the trimethoprim-resistant group when compared with the...

Trimethoprim resistance is increasingly prevalent in community-acquired urinary infections. The objective of this study was to evaluate the association between exposure to community-prescribed trimethoprim and other risk factors in subjects and subsequent trimethoprim-resistant urinary tract infection. The design was a nested case-control study using a record-linkage database. Study subjects su...

OBJECTIVES Trimethoprim-sulfamethoxazole may cause hyperkalaemia by the amiloride-like effect of trimethoprim on sodium channels in the distal nephron. Hyperkalaemia usually occurs after 7-10 days and has been reported in 20%-50% of patients receiving trimethoprim-sulfamethoxazole. Patients with Pneumocystis jiroveci pneumonia and severe hypoxaemia benefit from the use of prednisolone as an adj...
