Key Concepts

Cystitis

Cystitis is an inflammation of the bladder, often caused by a bacterial infection. It is characterized by symptoms such as frequent urination, pain during urination, and lower abdominal discomfort. Understanding the pathophysiology of cystitis is crucial for identifying its causative agents and appropriate treatments.

Common Uropathogens

Common uropathogens are bacteria that frequently cause urinary tract infections (UTIs), including cystitis. Escherichia coli (E. coli) is the most prevalent among these pathogens, accounting for the majority of cases. Recognizing these organisms helps in diagnosing and treating UTIs effectively.

Antibiotic Resistance

Antibiotic resistance refers to the ability of bacteria to withstand the effects of medications that once killed them or inhibited their growth. This phenomenon complicates the treatment of infections like cystitis, as resistant strains may not respond to standard antibiotics, necessitating alternative therapeutic strategies.
