Establishment and Characterization of UTI and CAUTI in a Mouse Model

The ability to model urinary tract infections (UTI) is crucial in order to be able to understand bacterial pathogenesis and spawn the development of novel therapeutics. This work’s goal is to demonstrate mouse models of experimental UTI and catheter associated UTI that recapitulate and predict findings seen in humans.

We are measuring perigenital mechanical sensitivity and mast cell activation in the prostate of male C57BL/6 mice that underwent an early life stress paradigm – neonatal maternal separation, in order to induce a preclinical model of chronic prostatitis/chronic pelvic pain syndrome.

Quantitative Assessment of Human Neutrophil Migration Across a Cultured Bladder Epithelium

We developed an in vitro model that mimics an important component of the acute inflammatory response during infection of the bladder with uropathogenic Escherichia coli. The transuroepithelial neutrophil migration assay enables quantitative assessment of human neutrophil migration across bladder epithelia, cultured on permeable supports, in response to bacterial infection or chemoattractant substances.
FAQs
Bacteria usually enter through the urethra, then multiply within the bladder. Their presence activates inflammation in the bladder lining, which disrupts normal urinary function and contributes to urgency, frequency, and painful urination. This sequence matters clinically because symptoms reflect both bacterial growth and the tissue response, rather than bacterial presence alone.
Infectious cases are associated with bacteria entering and multiplying in the bladder, whereas noninfectious cystitis can result from irritation or medication-related inflammation. The distinction cannot be made reliably from the symptom pattern alone, because urinary discomfort and altered urinary function may occur in either setting. Identifying the cause therefore directs appropriate clinical management.
Accurate diagnosis helps clinicians distinguish infection from noninfectious inflammation, so treatment can address the underlying cause rather than symptoms alone. It also supports efforts to prevent recurrence and lowers the risk that an infection will spread from the bladder to the kidneys. This is why evaluation remains important even when symptoms seem familiar.
A clinical evaluation may begin with a detailed assessment of urinary symptoms, including urgency, frequency, and painful urination. Clinicians may then use urinalysis and, when needed, urine culture to investigate whether infection is present or whether another cause better explains the bladder inflammation. This combined approach connects the patient’s experience with objective testing.
Urine culture is one of the clinical tests used alongside symptom assessment and urinalysis. Its role is to help distinguish a bacterial infection from noninfectious causes such as irritation or medication-related inflammation. That information is clinically useful because identifying the cause allows treatment decisions to be guided by the actual process affecting the bladder.
When evaluation identifies the relevant cause, treatment can be selected more accurately instead of assuming that every case results from infection. Appropriate management can help prevent recurrence and reduce the risk of an infection spreading to the kidneys. These outcomes make accurate clinical evaluation important whenever cystitis is suspected.
