“…The spores of Myxobolus eirasi Kaur et al [32] (parasite of Cirrhina mrigala in India), are morphologically comparable to those of our parasite, but shorter (8.4 μm-8.8 μm) with smaller polar capsules (1.4 μm-1.75 μm).…”

Examination of some Teleost fishes captured in the Maga detention lake located in the Far North Region of Cameroon, revealed the presence of three new species of Myxosporidia of the genera Myxidium Bütschli, 1882 and Myxobolus Bütschli, 1882 of which complete description is given in the present study. These species are: Myxidium tetraodoni sp. nov., parasite of the urinary bladder of Tetraodon lineatus Linnaeus, 1758 (Tetraodontidae) that form ellipsoidal spores with a turgid middle part and rounded ends. They measured 11.6 (10.5-12.5) µm long × 8.2 (7.2-9.6) µm broad; the spherical polar capsules are of equal size and measure 3.

“…Gill and dermal lesions due to myxozoan infection have been reported in many states of India (Chakravarty, 1939;Gupta and Khera, 1989;Padma Dorthy and Kalavati, 1992;Kalavati and Vaidehi, 1992;Mohan and Shanker, 1995;Kalavati and Nandi, 2007;Dar, 2013;Kaur et al, 2013). Besides this, many species of myxosporean parasites were recorded from freshwater fishes of wetlands of Punjab (Kaur and Singh, 2008, 2010a, 2010b, 2011a, 2011b, 2011c, 2011d, 2011e, 2011f, 2012a, 2012bSingh, 2011). In Punjab, the aquaculture is an upcoming practice being taken up by many farmers as the natural stock declined and representing it as the fastest growing animal husbandry.…”

A myxozoan parasite, Thelohanellus bifurcata Basu and Haldar, 1999 infecting gills of cultured major carp, Labeo rohita (Hamilton, 1822), rohu was collected from 4 fish farms in Patiala district (Punjab), India. The infection rate was 20% (3/15) and the age of the fishes examined was between 3-10 months. A total of 20-30% fish mortality was recorded which included young fish between the age of 3-4 months. Plasmodia were large, visible with naked eye, oval and creamish white in color enclosing 1000-1200 spores. Spores histozoic, large, elongate pyriform in shape, tapering anteriorly with a notch-like constriction at 3/4 th of the spore body and were characterized in having anteriorly bifurcated polar capsule. In histopathological sections each plasmodium occupied almost 15-25% of the gill filament. The cavity of the plasmodium was filled with spores and cellular debris. The pathogenesis caused by T. bifurcata was evident in cultured carps as infection caused severe damage to the gills leading to total loss of its respiratory surface. According to their location on the gill filament the plasmodia were of two types i.e. intrafilamental vascular type (FV 2 ) occupying the tip portion and intralamellar vascular type (LV 3 ) occupying side of the gill filament.All copyrights reserved to Nexus® academic publishers

“…Ziehl-Neelsen staining, used in the histopathological analyses, highlighted the polar capsules of the spores to identify spores with asymmetrical polar capsules dispersed throughout the nervous tissue ( Figure 2); Kaur & Singh (2009) used a similar histological technique to highlight the polar capsules of M. eirasi in Cirrhina mrigala.…”

The genus Myxobolus, parasites that infect fishes, which cause myxobolosis, includes spore organisms belonging to the phylum Myxozoa and represents approximately 36% of all species described for the entire phylum. This study describes lymphocytic meningoencephalomyelitis associated with Myxobolus sp. infection in the brain and spinal cord (the central nervous system, CNS) of Eigenmannia sp., from the Amazon estuary region, in the Administrative District of Outeiro (DAOUT), Belém, Pará, Brazil. In May and June 2015, 40 Eigenmannia sp. specimens were captured from this region and examined. The fish were anesthetized, slaughtered and dissected for sexing (gonad evaluation) and studying parasites and cysts; after diagnosing the presence of the myxozoans using a light microscope, small fragments of the brain and spinal cord were removed for histological processing and Hematoxylin-Eosin and Ziehl-Neelsen staining. Histopathological analysis of the brain and spinal cord, based on histological sections stained with Hematoxylin-Eosin, pronounced and diffuse edema in these tissues, and congestion, degeneration, and focal necrosis of the cerebral cortex. The present study describes lymphocytic meningoencephalomyelitis associated with infection by Myxobolus sp. in the central nervous system of Eigenmannia sp.
