“…The maximum similarity was obtained with M. haichengensis, which reportedly infects the gill filaments of Abbottina rivularis in China. The single species of Myxobolus sequenced from Cyprinidae collected in Cameroon was M. dibombensis (Lekeufack et al 2019), which exhibited only 83% similarity. The phylogenetic tree did not show strict clustering of selected species of Myxobolus according to geographic locality or tissue tropism.…”

We report a new myxozoan, Myxobolus opsaridiumi sp. nov., infecting the ornamental fish Opsaridium ubangiensis (Pellegrin, 1901) collected from the Anga River near the city of Yaounde, Cameroon. Plasmodia were found in the skin, muscles and spleen. The overall prevalence of infection was 54.7% (288 parasitized fish out of 526 examined). The myxospores were ovoid to subspherical in frontal view and lenticular in lateral view. The valves were symmetrical and relatively thick, without edge markings. The myxospore measurements were 10.7 ± 0.14 (10–11.5) μm long, 9 ± 0.15 (8–10) μm wide and 6.2 ± 0.7 (5.6–7.2) μm thick. The two ovoid polar capsules were equal in size, converging and opening together at the anterior end, measuring 5 ± 0.07 (4.3–6.0) μm long and 2.7 ± 0.07 (2.2–3.0) μm wide. Polar filaments were coiled from 5 to 7 turns. Histopathological analysis revealed no inflammatory reaction associated with the infection. A BLAST search found that the newly obtained 18 rDNA sequence had a low sequence similarity with available sequences for Myxobolus on GenBank. A phylogenetical analysis based on ribosomal DNA partial sequences showed that M. opsaridiumi sp. nov. is closely associated with several species of Myxobolus infecting cyprinid fish.

“…The location of plasmodia in interlamellar site was revealed to be associated with hypertrophy and inflammation. Lekeufack Folefack et al (2019), believe that rupture of cysts can lead to haemorrhages, and sometimes may result in considerable loss of blood. In case of severe infection, hypertrophy of the basal epithelial can lead to increase in mucus production.…”

Myxosporea are almost exclusively fish parasites and have been recognized as a key limiting factor in the development of aquaculture. For this, we aimed at studying myxosporean, parasites of Enteromius martorelli so as to facilitate their future comparative identification and provide histopathological data. The morphological and metric characteristics of myxospores harvested fit together with those of Myxobolus nyongana; Myxobolus oloi and Myxobolus njinei. Histological funding revealed that M nyongana form plasmodia in the lumen of vascular network directly at the base of the secondary gill lamellae and result in deformation of adjacent gill lamellae. Plasmodia of M. oloi were implanted between the muscle fibers and exert a mechanical pressure on the adjacent cells. M. njinei affected the fins and gill. Plasmodia of M. njinei on fins occur in three typical locations: between the finrays; inside the lumen of the finrays; and the outer surface of the hemisegments under the basal lamina. Parasites species harvested exhibited two type of specificity: euryxenous and mesostenoxenous. Given the lack of knowledge on pathogens that affect E. martorelli, data from the present study could be of considerable importance in the handling of the species under cultivation.
