Immunogenicity of different antigen preparations of outer membrane proteins (OMP) of Aeromonas hydrophila such as Poly d, l-lactide-co-glycolic acid (PLGA) microparticles, oil emulsion, neat OMP and bacterial whole cells were compared through intra-peritoneal injection in fish, Labeo rohita. Among these preparations, PLGA encapsulated antigen stimulated(More)
Lack of immune competence in the early stages of life leads to severe mortality in larval stages of different fish species including Indian major carp (IMC). Investigation through indirect enzyme linked immunosorbent assay (ELISA) and agglutination test revealed a significant increase in specific serum antibody response in the brood fish of Indian major(More)
Different non-specific immune parameters and their seasonal changes in brood Indian major carp Labeo rohita reared in two major freshwater aquaculture regions of India viz. West Bengal and Orissa were investigated. It was undertaken for 2 consecutive years and included three main seasons of a year such as summer (March-May), rainy (July-September) and(More)
An 84-day feeding trial was conducted to study the effect of replacing dietary fishmeal with dried chicken viscera meal (CVM) on the growth (net biomass gain, specific growth rate, SGR), feed acceptability, feed conversion ratio (FCR), protein efficiency ratio (PER) and carcass composition of Clarias batrachus fingerlings. Triplicate groups of fingerlings(More)
Spermatogenesis is a highly co-ordinated and complex process. In vitro propagation of spermatogonial stem cells (SSCs) could provide an avenue in which to undertake in vivo studies of spermatogenesis. Very little information is known about the SSC biology of teleosts. In this study, collagenase-treated testicular cells of farmed catfish (Clarias batrachus,(More)
An epidemiological investigation was carried out to know the prevalence of Dental Caries amongst 1257 children in the age group of 5, 8, 11 & 15 years respectively attending schools in the city of Cuttack, Orissa. The examination was carried out under natural light and dental caries was diagnosed according to W.H.O. Criteria 1983. The point prevalence of(More)
An in situ modified Hummers method (without the use of any surfactants) has been used for the deposition of bismuth (Bi) nanoparticles onto the surface of reduced graphene oxide (RGO) sheets. The as-synthesized nanocomposites were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, transmission(More)
To overcome the limitations of the use of conventional liposomes chitosan coated egg yolk lecithin based liposomes were used as antigen carrier through parenteral administration in two animal models such as fish and rabbit. Extracellular proteins (ECPs) antigen of Aeromonas hydrophila encapsulated in liposomes became more stable and induced better immune(More)
Common name: Magur, Walking Catfish. Conservation status: Vulnerable (CAMP 1998). Identification: Brownish black in colour. Elongated body with round abdomen and laterally compressed tail. Head with two depressions. Upper jaw slightly longer than lower. The mouth is wide and terminal. Four maxillary and four mandibular barbells. The dorsal fin and anal fin(More)
Induced spawning of C. batrachus was conducted at different Ovaprim dose and latency period combinations to observe the deformed larvae among the hatchlings. For the purpose, four doses of Ovaprim (0.5, 1.0, 1.5 and 2.0 ml/kg body weight) and five latency periods (11, 14, 17, 20 and 23 hr) were considered in 20 different combinations. There were no deformed(More)
