Histopathological effects in gills, heart, liver, spleen, intestine and genital organs of
carangid fishes Carangiodes malabaricus and Megalaspis cordyla infection with
trypanorhynch cestodes [Callitetrarhynchus gracilis, Callitetrarhynchus sp., Floriceps
minacanthus, Progrillotia sp. and Pseudogrillotia spratti] were studied. A total of 86 fishes
samples were collected during the period between September 2011 till March 2012. Fish
samples were obtained from northwest Arab Gulf, Iraq [latitudes 47° 30′ to 48° 15′;
longitude 30° 50′ to 30° 00′]. It was found the macroscopic lesions represented
hemorrhagic congestion, patches and redness around the heart, spleen, liver and
intestines. The microscopically showed that thickening in the lamella and the presence of
foreign bodies may be from parasites, collected acidophilic materials, erosion,
hyperplasia of lamina propria of the intestine and infiltration and expansion of blood
vessels around the heart area.
