Renal Disease in Teleost Patients

Cutaneous nerve sheath tumours, non‐infectious polycystic kidney disease, renal granulomas, nephrocalcinosis and crystals: Incidental pathological findings in pond‐living goldfish (Carassius auratus, Linnaeus)

“…There are currently no known medical treatments. 9 In the non-infectious PKD here described, the absence of clinical scale protrusion could suggest a partially conserved function of the nephrons. Nevertheless, the lack of any clinical, diagnostic imaging and haematological data excludes the possibility of confirmation of this assumption.…”

“…The condition is progressive and leads to the eventual death of the animal. There are currently no known medical treatments 9 . In the non‐infectious PKD here described, the absence of clinical scale protrusion could suggest a partially conserved function of the nephrons.…”

“…Unfortunately, there is no known treatment for this condition; management for this pathogen involves decreasing the area for oligochaete worms that reside in the pond. 9 Histologically, the parasite may trigger papillomatous cystic hyperplasia of the renal tubular epithelium and subsequent degeneration of the interstitium. Glomeruli are rarely involved.…”

“…It is caused by the myxozoan Hoferellus carassii that, for the vital cycle, requires two aquatic oligochetes as intermediate hosts. Unfortunately, there is no known treatment for this condition; management for this pathogen involves decreasing the area for oligochaete worms that reside in the pond 9 . Histologically, the parasite may trigger papillomatous cystic hyperplasia of the renal tubular epithelium and subsequent degeneration of the interstitium.…”

“…Casos graves de distensão da cavidade celomática também podem ocasionar a protrusão das escamas devido a compressão do inchaço contra a parede do tronco do animal, levando ao eriçamento das escamas. As causas para a distensão celomática são variadas, podendo ser devido a infecções, como por bactérias e vírus, assim como por causas não infecciosas, como cistos ovarianos e renais (SMITH, 2019;WEBER, 2020). Situações de estresse, como transporte, má qualidade de água e má alimentação, podem deixar os peixes mais suscetíveis a bactérias que provocam o acúmulo de líquido intracelomático (SMITH, 2019), no estudo estes fatores foram relacionados ao diagnóstico de doença sistêmica granulomatosa, lesões de brânquias, fígado e renais.…”
