A histopathological study of carp (Labeo rohita) ABSTRACT Indian major carp (Labeo rohita) were exposed to 1/10 and 1/5 sub-lethal doses of hexachlorocyclohexane during a 45-day trial period. Fish were sacrificed at the end of the trial period to study light microscopic changes associated with toxicity. Organ tissues, viz., liver, kidney, gill, skin,(More)

The present study was carried out to study the effect of different dosages of β-glucan suspension on immune response and disease resistance in Anabas testudineus spawns against a fungal pathogen Saprolegnia parasitica. Eight day old spawns were exposed for 3 h in four different dosages of β-glucan suspension in phosphate buffered saline at the rate of 0, 5,(More)
Rhizobia diversity is considered as one of the most useful resources for bioprospecting due to their symbiotic nitrogen-fixing ability with members of Leguminosae. The highly conserved nature of the nitrogenase reductase gene (nifH) makes it an ideal molecular tool to determine the potential for biological nitrogen fixation in any environment. In the(More)
The phytochemical screening of the various extracts of Spirodela polyrrhiza revealed the presence of alkaloids, steroids, flavonoids and saponins. Fourteen fractions were elucidated from the ethanolic extract using the silica gel column chromatography. Antimicrobial activities of the ethanol and fractions of ethanolic extract of S. polyrrhiza against(More)

The purpose of the current work was to conduct phytochemical screening and antioxidant activity of different extracts of Leucas aspera. The dried powder of the whole plant was extracted with n-hexane, ethyl acetate and ethanol which were subjected to various chemical tests to ascertain the main constituents of the plant. The results revealed the presence of(More)
