Bacterial diseases cause tilapia's high‐mortality outbreak. This study investigated the toxicity of azithromycin (AZT), a macrolide antibiotic that has been considered a possible therapeutic drug for tilapia aquacultural use. The 48‐h acute toxicity (50% lethal concentration, LC50; 48 h) of AZT was determined for Oreochromis niloticus. Thereafter, fish were exposed to 0, 1, 50 and 100 mg L?1 AZT during 14 days (chronic exposure) and measured the haematological variables, the activity of superoxide dismutase, catalase, glutathione peroxidase, glutathione‐S‐transferase (GST) and the concentration of glutathione (GSH), protein carbonyl and lipid peroxidation in the liver; histopathology was analysed the liver, gills and kidneys. The LC50; 48 h was >100 mg L?1. No fish died during chronic exposure. Haematocrit and haemoglobin concentration increased in fish exposed to 50 and 100 mg L?1, and the total number of leucocyte and thrombocyte increased after exposure to 100 mg L?1 AZT, suggesting a stimulation of defence cell production. In the liver, the antioxidant enzyme activities did not change, but GST activity and the GSH level increased in fish exposed to 100 mg L?1 AZT. Oxidative stress did not occur. Histopathological index (HIL) indicates moderate liver damage; minor histological changes in the gill and no change in the kidneys. AZT was considered non‐toxic for O. niloticus after acute exposure and, although it causes moderated histopathology in the liver after chronic exposure, this antibiotic may be an alternative against bacterial infections, depending on its efficacy to control bacterial disease in fish. 相似文献

The increased use of marginal quality water with drip irrigation requires sound fertigation practices that reconcile environmental
concerns with viable crop production objectives. We conducted experiments to characterize dynamics and patterns of soil solution
within wet bulb formed by drip irrigation. Time-domain reflectometry probes were used to monitor the distribution of potassium
nitrate (KNO3) and water distribution from drippers discharging at constant flow rates of 2, 4 and 8 L h−1 in soil-filled containers. Considering results from different profiles, we observed greater solute storage near the dripper
decreasing gradually towards the wetting front. About half of the applied KNO3 solution (48%) was stored in the first layer (0–0.10 m) for all experiments, 29% was stored in the next layer (0.10–0.20 m).
Comparing different dripper flow rates, we observed higher solution storage for 4 L h−1, with 45, 53 and 47% of applied KNO3 solution accumulating in the first layer (0–0.10 m) for dripper flow rates of 2, 4 and 8 L h−1, respectively. The results suggest that based on the volume and frequency used in this experiment, it would be advantageous
to apply small amounts of solution at more frequent intervals to reduce deep percolation losses of applied water and solutes. 相似文献
