Capillariasis

Capillaria plica is a parasite that invades the mucosa or submucosa of the bladder or (rarely) the renal pelvis and ureter, causing a mild inflammatory response.
C. plica in dogs and cats and C. feliscati in cats have been uncommonly associated with signs of lower urinary tract disease.
First stage in life cycle of C. plica is passage of bipolar ova in urine. After earthworms ingest embryonated ova, the parasite develops into the infective stage. Ingestion of infective earthworm results in a patent infection in dogs in 58–88 days.
Details of life cycle of C. feliscati are poorly understood.
