Microbial phosphate solubilisation as influenced by sodium chloride

Mon, 01 Feb 1999 00:00:00 GMT

Title: Microbial phosphate solubilisation as influenced by sodium chloride Authors: Gaind, Sunita; Gaur, A C Abstract: A thermotolerant phosphate solubilizing bacteria was tolerant to salt stress and could solubilise P₂O₅, (56 %) at sodium chloride concentration of 3.5 %, whereas, Bacillus polymyxa and a Bacillus sp. were sensitive. Turbidity and pH showed no correlation with phosphate solubilization by these bacteria. Page(s): 209-210

Biological activity of indigenous plant extracts as mosquito larvicides

Mon, 01 Feb 1999 00:00:00 GMT

Title: Biological activity of indigenous plant extracts as mosquito larvicides Authors: Latha, C; Vijayakumar, P D; Velayudhan, Saleena; Joseph, Ammini Abstract: Petroleum ether extracts of 41 indigenous plants abundant in different parts of Kerala were studied for the larvicidal activity against the urban mosquito, Culex quinquefasciatus and the saline water mosquito, Culex sitiens. The extracts of 18 plants showed larvicidal activity against the early fourth in star larvae of Cx. sitiens. Two plant species Piper longum and Zingiber wightianum were effective against the early fourth instar larvae of Cx. quinquefasciatus and ex. sitiens. Therefore, the plant species P. longum and Z. wightianum were identified as potential biopesticides. Page(s): 206-208

Immunization of cattle against Hyalomma anatolicum anatolicum using larval antigens

Title: Immunization of cattle against Hyalomma anatolicum anatolicum using larval antigens Authors: Ghosh, S; Khan, M H Abstract: Development of immunity in cross-bred (Bos taurus x Bos indicus) calves against Hyalomma analolicum analolicum, vector of bovine tropical theileriosis, was studied using larval antigen (LS) in Freund's complete adjuvant (FLA). Calves immunized with LS + FCA showed significant rejection of larvae (57.25±6.8) and nymphs (45.75 ± 5.16). Abnormally fed larvae (11.4 ± 0.8) and nymphs (8.25 ± 1.2) were also recovered from immunized calves. This abnormal feeding may possibly be attributed to their inability to gain access to the blood vessels owing to the host immunological reactions. Consequently, feeding of extravascular fluid leads to white colour of fed ticks. Sera from all immunized calves after a week of immunization were positive for anti-LS antibodies in ELISA. The investigation indicates that LS in FCA enhanced anti-tick immunity. Page(s): 203-205

Effects of vanadate, insulin and fenugreek (Trigonella foenum graecum) on creatine kinase levels in tissues of diabetic rat

Title: Effects of vanadate, insulin and fenugreek (Trigonella foenum graecum) on creatine kinase levels in tissues of diabetic rat Authors: Genet, Solomon; Kale, Raosaheb K.; Baquer, Najma Z. Abstract: The in vivo effects of insulin, and other insulino mimetic agents like vanadate and fenugreek (T. foenum graecum) were followed on the changes in the activit ies of creatine kinase in heart, skeletal muscle and liver of experimental diabetic rats. As compared to control rats, creatine kinase activities were found to decrease significantly in the tissues during experimental diabetes. All the antidi abetic compounds used namely, insulin, vanadate and Fenugreek seed powder normalised the decreased activities to almost control values. The effects of insulin and vanadate were comparable in restoring normoglycemia and the creatine kinase activities. Page(s): 200-202
