In this study, we examined the microbial population in different parts, gill, muscles and intestine region of Channa punctatus from two different fish culture farm. Based on their growth characteristics on specific culture media, the following human bacterial pathogen such as Achromobacter xylosoxidans (Gram +ve), Acinetobacter anitratus (Gram -ve), Bacillus subtilis (Gram +ve), Proteus vulgari...

In the intestine of 10 (n = 18) cyprinid fish species collected from natural waters of Hungary, the author demonstrated oocysts which were shed unsporulated In tapwater, oocysts sporulated within 24 to 48 h In 6 of the fish species, oocysts of 2 sizes were observed Histological examnations proved that, of the morphologically similar oocysts larger ones developed in nodules in size of a pinhead ...

The magnesium handling of freshwater teleost fish is discussed, with an emphasis on the role of branchial, intestinal and renal transport. In response to the eminent threat of constant diffusive losses of minerals such as magnesium, freshwater fish have developed efficient mechanisms for magnesium homeostasis. Magnesium losses are overcome by the uptake of magnesium from the food, making the in...

Abstract This paper applies a new approach to the identification of discourses, based on Multiple Correspondence Analysis (MCA), study discourse variation over time. The MCA keywords deals with major issue use identify discourses: allocation individual multiple discourses. Yet, as this demonstrates, also allows us observe in prevalence discourses texts patterns keyword co-occurrence. Metadata c...

diazinon is a moderately persistent organ phosphorus pesticide largely used in agriculture. thepurpose of this study was to evaluate the histopathological damages induced by diazinon in gills, kidney,spleen, and intestine tissues of rainbow trout, oncorhynchus mykiss. the fishes were exposed to sub-lethalconcentrations of diazinon (0.1 and 0.2 mg/l) for a period of 28 days. tissues analyzed by ...
