Cystitis: Significant Associations Between Pathology, Histology, and Quantitative Bacteriology in Sows, a Cross-Sectional Study

The importance of cystitis in pig production is controversial and sparse information is available on its frequency and etiology in sows. The aim of this study was to determine the prevalence of bacteriuria, macroscopical and histological lesions of the urinary bladder in culled sows. Urinary bladders and urine samples were obtained from 176 culled sows at slaughter. The urine samples collected by cystocentesis were analyzed to determine bacterial content and pathological findings, macroscopic as well as microscopic, of the bladder were recorded for each sow. The prevalence of bacteriuria, defined by bacterial concentrations ≥ 103 colony forming units per mL of urine, was 34
