The chondracanthid copepod, Chondracanthus goldsmidi is an ectoparasite of gills, inner opercula and nasal cavities of cultured striped trumpeter, Latris lineata (Forster). Whilst often present in high numbers (up to 60 parasites per host), little is known about its effect on striped trumpeter. In this study C. goldsmidi was associated with extensive epithelial hyperplasia and necrosis. Pathological changes were most pronounced near the parasite's attachment site, with papilloma-like growths surrounding the entire parasite resulting in deformation of the filament. The number of mucous cells increased near the parasite attachment sites on both the opercula and gills. Mast cells were absent in healthy gills; in contrast numerous mast cells were identified in the papilloma-like growths. Immunostaining identified piscidin-positive mast cells in the papilloma-like growths, presenting the first evidence of piscidin in the family Latridae.
chondracanthid 桡足类 copepod，Chondracanthus goldsmidi 是养殖条纹笛鲷（Latris lineata (Forster)）的鳃、内鳃盖和鼻腔的外寄生虫。虽然它通常存在于大量的宿主中（高达 60 个寄生虫/宿主），但对条纹笛鲷的影响知之甚少。在这项研究中，C. goldsmidi 与广泛的上皮细胞增生和坏死有关。病变在寄生虫附着部位最为明显，整个寄生虫周围有类似乳头瘤的生长，导致丝状体变形。在鳃盖和鳃上，寄生虫附着部位附近的粘液细胞数量增加。健康的鳃中没有肥大细胞；相比之下，在类似乳头瘤的生长物中发现了大量的肥大细胞。免疫染色在类似乳头瘤的生长物中鉴定出含有鱼精蛋白的肥大细胞，这是首次在 Latridae 科中发现鱼精蛋白。
