| Description | Fish nematodes are important group of parasites, because it can cause several serious diseases. They can infect any part of the fish body, including the body cavity, internal organs, deeper layers of the skin or fins, and external muscle layers as adults or as larvae. SEM of their outer morphology revealed, that under this name is several morphospecies hidden. Procamallanus laeviconchus sensu lato is quite common nematode of various African fish species and has a Pan-African distribution. It has indirect life cycle, crustaceans (copepods) serve as intermediate hosts. Camallanid specimens were recovered mainly from stomachs of catfishes from different families. For study of important, however poorly recognizable morphological structures, light microscopy (LM), scanning electron microscopy (SEM) and partially also environmental scanning electron microscopy (ESEM) were used. Samples were prepared by standard methods for SEM and examined using a Quanta TM 250 FEG SEM at an accelerating voltage of 10 kV or JEOL JSM-7401F FE SEM at an accelerating voltage of 4 kV. |
