The aim of this study was to demonstrate and assess C-reactive protein (CRP) changes in dogs with induced bacterial cystitis with or without antibiotics. We also evaluated availability of CRP levels to serve as an indicator for monitoring or diagnosing bacterial cystitis. Serial CRP concentrations in dogs with induced bacterial cystitis were higher than those of controls (p < 0.001). CRP concen...

BACKGROUND Cathelicidin is a proposed defender against infection of the urinary tract via its antimicrobial properties, but its activity has not been delineated in a dedicated cystitis model. METHODS Female C57Bl/6 mice, wild type or deficient in cathelin-related antimicrobial peptide (CRAMP; an ortholog of the sole human cathelicidin, LL-37), were infected transurethrally with the cystitis-d...

Urinary tract infections (UTIs) afflict over 9 million women in America every year, often necessitating long-term prophylactic antibiotics. One risk factor for UTI is frequent sexual intercourse, which dramatically increases the risk of UTI. The mechanism behind this increased risk is unknown; however, bacteriuria increases immediately after sexual intercourse episodes, suggesting that physical...

Hemorrhagic cystitis is defined by lower urinary tract symptoms that include dysuria, hematuria, and hemorrhage and is caused by viral or bacterial infection or chemotherapeutic agents. Reports of hemorrhagic cystitis caused by non-typhoidal salmonella (NTS) are extremely rare. We report a case of a 41-year-old man with hemorrhagic cystitis from NTS that caused massive bleeding and shock. The p...

Bacterial cystitis accounts for the majority of urinary tract infection (UTI). It is frequently found in young, otherwise healthy females showing no signs anatomical or physiological defects. Among young women who have experienced an episode acute bacterial cystitis, 25% to 50% develop recurrent episodes. Individuals with episodes a greater susceptibility urogenital colonization uropathogens th...

Chronic infections are an increasing problem due to the aging population and the increase in antibiotic resistant organisms. Therefore, understanding the host-pathogen interactions that result in chronic infection is of great importance. Here, we investigate the molecular basis of chronic bacterial cystitis. We establish that introduction of uropathogenic E. coli (UPEC) into the bladders of C3H...

Bacterial virulence factors influence the site and severity of urinary tract infections. While pyelonephritis-associated molecular traits have been defined, virulence factors specific for acute cystitis strains have not been identified. This study examined the virulence factor repertoire of 247 Escherichia coli strains, prospectively isolated from women with community-acquired acute cystitis. F...

Background & Aims: Urinary tract infection (UTI) is one of the most frequently acquired bacterial infections caused by a large genetically heterogeneous group of Escherichia coli which are called uropathogenic E. coli (UPEC). Cystitis and pyelonephritis are two most common symptoms seen in patients with UTI. The genetic diversity of this organism has hampered the identification of UTI strains a...

Interstitial cystitis is a chronic, severely debilitating disease of the urinary bladder. Excessive urgency and frequency of urination, suprapubic pain, dyspareunia, chronic pelvic pain and negative urine cultures are characteristic of interstitial cystitis. The course of the disease is usually marked by flare-ups and remissions. Other conditions that should be ruled out include bacterial cysti...

BACKGROUND Long-duration beta-lactam antibiotics are used for empirical treatment in female dogs with uncomplicated bacterial cystitis. However, women with bacterial cystitis are treated with short-duration potentiated sulfonamides because longer courses of beta-lactams result in lower cure and higher recurrence rates. HYPOTHESIS/OBJECTIVES Short-duration potentiated sulfonamide treatment is ...
