Figure 2From: Effects of temperature on Veronaea botryosa infections in white sturgeon Acipenser transmontanus and fungal induced cytotoxicity of fish cell linesHistologic findings in white sturgeon fingerlings challenged by intramuscular injection with Veronaea botryosa at 13 °C. A Low magnification photomicrograph of an irregular area of granulomatous inflammation (arrows) radiating into skeletal muscle at the injection site. H&E stain, Bar = 500 μm. B Higher magnification image of muscle lesion. Inflammatory infiltrates were dominated by macrophages, with smaller numbers of multinucleated giant cells and lymphocytes. H&E stain, Bar = 100 μm. C Spleen, multinucleated giant cell containing pigmented hyphal fragments (arrow). H&E stain, Bar = 20 μm. D Kidney, giant cells with hyphal fragments (arrow) surrounded by hematopoietic tissue and renal sinusoids. H&E stain, Bar = 20 μm.Back to article page
