Description of four new Myxosporean species (Myxozoa: Myxosporea) from genus Myxobolus, fish parasites of Burkina Faso, West Africa

Abstract

The Myxosporean met in freshwater fishes of Burkina Faso, form all of them some whitish cysts on the fins for Myxobolus labeoi sp. n. and Myxobolus tingrelaensis sp. n. and on the branchial for Myxobolus heterotisi sp. n. and Myxobolus sourouensis sp. n. The spores of M. heterotisi sp. n. are ootid, they measure 2.13±0.46 out of 9.51±0.45 μm and have their anterior extremity slightly contracted. Their pyriform polar capsule measure 6.41±0.41 out of 3.53±0.51 μm. The polar filament is rolled in 10 turns of spires. M. labeoi n. sp. Presents some lengthened spores of 16.43±0.50 out of 10.73±0.52 μm. The dissymetrical polar capsules measure 8.37±0.56 out of 6.53±0.68 μm and 1.57±0.17 out of 0.35±0.09 μm. On M. sourouensis sp. n., the spores measure 11.33±0.33 out of 8.84±0.72 μm. The polar capsules are ootid measuring 5.77±0.73 out of 2.32±0.46 μm. M. tingrelaensis sp. n. form some ootid spores of 11.6±0.62 out of 9.37±0.67 μm. The pyriform polar capsules are 4.80±0.55 out of 2.40±0.38 μm and have a small inter-capsular appendix. © 2006 Asian Network for Scientific Information.
