“…However, the number of papers describing new myxozoan species from North and South America (Cone et al 2004;Eiras et al 2010), from Asia (Baska et al 2009;Kaur and Singh 2010), from Africa (Abdel-Ghaffar et al 2008), and from marine fishes (Ali et al 2007) have been constantly increasing in recent years.…”

Differentiation of Myxobolus spp. (Myxozoa: Myxobolidae) infecting roach (Rutilus rutilus) in Hungary

During a survey on fishes from Hungarian freshwaters, the occurrence of eight Myxobolus species was registered in roach (Rutilus rutilus L.). Most species had a specific location within the fish host. Of the known species infecting roach, the intramuscularly developing species Myxobolus pseudodispar was found to be the most common. Besides Myxobolus intimus and Myxobolus diversicapsularis infecting the capillary network of gill lamellae, Myxobolus feisti infecting the cartilaginous gill rays were observed. Of the "muelleri-type" Myxobolus spp, Myxobolus rutili and Myxobolus sommervillae sp. n. formed elongated plasmodia in the gill filaments outside and inside the arteria efferens, respectively, while Myxobolus wootteni sp. n. developed cysts in fins. Plasmodia and spores of Myxobolus fundamentalis sp. n. were detected in the cartilaginous gill arch under the basis of gill filaments. Despite similarities of some species in spore morphology, 18S rDNA sequences and phylogenetic analyses showed clear differences among all species examined. The findings of the study demonstrate that morphologically similar spores could only be correctly identified by considering the location of plasmodia and the genetic characters of the myxozoan species.

“…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

During the present study two new species were collected from mucous membrane around gill lamellae of Puntius sophore (Ham.) vern. chittal and Cirrhina mrigala (Ham.) vern. mrigal from Harike Wetland, Punjab respectively. Spore of the first species i.e. Myxobolus chittalii are histozoic, pear shaped with characteristic nipple-like anterior end and rounded posterior end. They measure 9.0 × 6.18 μm. Polar capsules are two, equal, measuring 4.5 × 2.4 μm, pyriform with bluntly pointed anterior end and rounded posterior end. They are placed posteriorly from the tip of the spore and are parallel to each other in the spore body cavity. A prominent, tongue shaped intercapsular process is present. Spores of the second species i.e. M. mehlhorni are histozoic, oval to egg in shape having narrow, blunt anterior end and broad rounded posterior end, measure 8.9 × 6.8 μm. Shell valves smooth, symmetrically thin, measure 0.5 μm in thickness. Parietal folds are absent. Polar capsules two, prominently unequal, placed anteriorly and converge towards the anterior end. Both polar capsules are flask-shaped with anterior end having a prominent neck. The larger polar capsule measure 3.7 × 2.5 μm occupying less than half while the smaller one measure 2.6 × 1.5 μm and occupy less than one-third of the spore body cavity. An intercapsular process is absent.
