Doctor fish (Garra rufa) have recently been used for aesthetic purposes and as a medical treatment in patients with psoriasis (ichthyotherapy). For this particular kind of human therapy it is essential to guarantee adequate hygienic conditions for both people and fish. The aim of this study was to test two concentrations of water disinfectants, chloramine T and peracetic acid, on Garra rufa to ascertain possible exposure damage to the epidermis and gills. Fish were exposed to 2 mg/l and 10 mg/l of chloramine T and to 15 μl/l and 45 μl/l of peracetic acid in a 40-minute static bath up to six times a day for one week. The epidermis and gills were checked for histological changes and the number of epidermal mucous cells, club cells and taste buds were quantified; mucous cells were also characterized histochemically to detect alterations in mucin production. No mortality or severe histological changes were found in treated or control fish. Cell count showed a significant increase (p<0.05) in mucous cells (mean 49.1 ± 6.7 vs 37.0 ± 13.1 of controls) in animals treated with peracetic acid independently of the dose. Club cell number showed a significant (p<0.05) decrease in fish treated with 2 mg/l of chloramine T (mean 74.3 ± 15.6) and with 45 μl/l of peracetic acid (mean 78.17 ± 10.5) compared to controls (mean 107.0 ± 19.2). Histochemical evaluation of mucous cells did not reveal changes in mucin type in fish exposed to the two disinfectants. The results suggest a good tolerability of Garra rufa to the two disinfectants at the concentrations tested.
