Abstract Objective: Catfishes harbour a greater variety and occurrence of larval helminth parasites because they are exposed to more infective helminth larvae in their diet due to their predatory habit which makes them more susceptible to higher parasitic burden. This study was conducted at department of zoology in Post Graduate Campus, Biratnagar, Nepal to determine the prevalence of helminth parasites in the gastrointestinal tract of two species of catfishes i.e Clarias gariepinus and Heteropneustes fossilis collected from the different water resources of Biratnagar, Eastern Nepal.Results: Out of 280 fish examination, 264 (94.28%) fishes were found to be infected with helminths parasites. Clarias gariepinus infection rate was 84.0% with three species of parasites, one each of nematode i.e. Procamallanus laevionchus, cestode i.e. Proteocephalus species, and trematode i.e. Allocreadium species. Heteropneustes fossilis have prevalence rate of 100% with five species of helminth parasites i.e. two nematode species namely Procamallanus heteropneustes and Eustrongyloides species, one cestode namely Lytocestus indicus, one trematode i.e. Phyllodystomum folium and an acanthocephalan i.e. Pomphorhynchus species were detected.

The purpose of this research was to describe the characteristics and number of microbes that grow in the gastrointestinal tract of catfish and to determine the potential of microbes as probiotics. The type of this research was observational conducted on 30 September-15 October 2018 at the Microbiology Laboratory, Faculty of Science and Technology, Universitas Airlangga, Surabaya. Microbial isolation using NA (Nutrient Agar), MRSA (de Man, Rogosa and Sharpe Agar) and PDA (Potato Dextrose Agar) media. The fish that used is catfish that are bred in ponds at Desa Tlasih, Kecamatan Tulangan, Kabupaten Sidoarjo, East Java. The identification includes microscopic and macroscopic characteristics. Based on the research that has been done, it can be concluded that there are 8 kinds of bacterial colonies in NA media, on PDA media there are 8 kinds of fungi, and on MRSA media there are 2 bacterial colonies and each has different macroscopic and microscopic characteristics. The total number of bacteria growing in NA and MRSA media respectively were 8.7 x 104 CFU / gram and 1.2 x 105 CFU / gram. It is suspected that there are potential bacteria as beneficial probiotics for catfish which still need further research. Keywords: catfish, gastrointenstinal tract, microbes, bacteria, fungi

African Sharptooth Catfish

The article presents specific features of adaptive response of stomach tissues of African sharptooth catfish bred in artificial environment with application of “Sporothermin” probiotic. Probiotics influence metabolism of the host organism due to their participation in digestion processes, they also promote synthesis of proteins and increase the degree of absorption. The microorganisms that compose the probiotic contribute to better assimilation of incoming nutrients into the fish organism, they synthesize biologically active substances due to their fermentation activity. Histological slides were analyzed and documented applying a universal microscope Axio Imager.M2. Differences were found in structural features of the stomach of fish bred with application of “Sporothermin” probiotic and without it. Thus, fish that did not receive the probiotic had edema of the stomach inner muscular layer, epithelial layer detachment from the gastric mucosa and disorder of structural organization of the gastric fields. These changes were not observed in fish bred with application of “Sporothermine” probiotic. The conducted studies indicate the prospects of using the microbiota with probiotic properties when breeding Clarias gariepinus in an artificial environment. The spore forms of bacteria (Bacillus subtilis, Bacillus licheniformis), which are part of the probiotic “Sporothermin”, contribute to improvement of microbiocenosis of fish gastrointestinal tract, triggering a mechanism that stimulates a complex of adaptive reactions in stomach tissues of Clarias gariepinus. At the same time, conditionally pathogenic and pathogenic microbiota in the gastrointestinal tract is suppressed, ensuring effective digestion and increasing the degree of nutrient absorption. As a result, the productivity of the fish stock increases and the costs of breeding it in an artificial environment are reduced.

Heterobranchus Longifilis

The structure of the pectoral fins spine of 4 catfish species Heterobranchus longifilis, Clarias gariepinus, Chrysichthys auratus, Synodontis schall and Synodontis serratus were described. The fish specimens were collected from Asyut City and Lake Nasser about 319 and 900 Km south of the capital Cairo, Egypt respectively on 10 November 2017 are described. The species examined showed variation in the shape of the spine-shaft tip varies from finely to broadly and rounded pointed; the curvature of the spine-shaft is either straight or curved partially or complete; the anterior serrae varies between is either broad or irregular; the anterior ridge groove is well developed, deep, and curved, with some pores in some species; the anterior dentations varies between short and sometimes are merged together or curved and their number decreased towards the tip; the posterior dentations can vary between absent or long and numerous and sometimes increased in their number towards the tip of the spine; the dorsal, anterior and ventral processes are well developed structures, with rounded, flange-like, and the shape of the basal fossa varies in having narrow, elongated, boat-shape, with high walls at sides; and very wide fossa and lunate in shape. It is usually deep with high walls.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).
