Study Notes
- Antibiotics like Trimethoprim, sulfamethoxazole, Fosfomycin, Nitrofurantoin, Cephalexin, and Ceftriaxone are commonly used to treat UTIs.
- Factors contributing to urinary tract infections (UTIs) include age (very young and old individuals are at higher risk), gender (more common in females due to anatomy), instrumentation like catheters, neurogenic bladder dysfunction, obstruction, underlying diseases like diabetes, and vesico-ureteral reflex.
- UTIs can lead to systemic infections like urosepsis when the infection spreads to the bloodstream causing a systemic infection.
- Common causative agents of UTIs are gram-negative rods like Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Proteus spp., as well as Enterococci and Staphylococcus saprophyticus.
- Criteria for evaluating urine cultures include specimen type, significant pathogen colony-forming units (CFU/ml), and interpretation of culture results indicating UTI presence.
