In a parasitology survey of Hungarian fishes, heavy infections of parasitic copepods Lamproglena pulchella and a Lamproglena sp. were found in the gills of the asp and the European catfish, respectively. Individuals of both fish species were emaciated and infected with hundreds of Lamproglena. Copepods located close to the tip of gill filaments and formed a depression at the attachment sites. In histological sections, cell degenerations and local haemorrhages were present adjacent to the maxillipeds and where the maxillary claws pierced the gill tissue. Around maxillae and in the midgut of the Lamproglena, damaged piscine blood cells and remains of the gill tissue were observed. Host reaction was expressed by proliferation of epithelioid cells, increase in both number and size of goblet and mast cells and formation of giant cells.
在一项对匈牙利鱼类的寄生虫学调查中，分别在赤梢鱼和欧洲鲶鱼的鳃中发现了大量寄生桡足类美丽灯镖水蚤和一种灯镖水蚤属物种的感染。这两种鱼类个体均消瘦，且感染了数百只灯镖水蚤。桡足类位于鳃丝末端附近，并在附着部位形成凹陷。在组织学切片中，靠近颚足以及上颚爪刺入鳃组织的部位出现了细胞退化和局部出血。在灯镖水蚤的上颌周围和中肠中，观察到了受损的鱼类血细胞和鳃组织残余物。宿主反应表现为上皮样细胞增殖、杯状细胞和肥大细胞数量及大小增加以及巨细胞形成。
