The aim of this work is to develop a membrane-based cost-effective process for the rapid isolation of immunoglobulin from chicken egg yolk. It was found that a single-stage ultrafiltration using a 100 kDa molecular weight cut-off regenerated cellulose membrane could be employed to isolate immunoglobulin from the crude feedstock. The effects of operational parameters (solution pH, ionic strength, stirring speed and permeate flux) on the transmission of immunoglobulin and the presence of impurity protein with molecular weight close to immunoglobulin were quantified using the parameter scanning ultrafiltration technique. Under optimized conditions, the purity of immunoglobulin obtained was about 85 percent after the single-stage ultrafiltration process, and the recovery of immunoglobulin from the feedstock was 91 percent.

Antivenom antibodies were generated in white leghorn chicken against bentonite and adjuvant coated venoms of Common Indian Poisonous Snakes (Cobra, Krait, Russell's viper and Saw Scaled viper).The antivenom from immunized chicken egg yolk were purified by polyethylene glycol (PEG) and ammonium sulphate precipitation method and further purified by DEAE cellulose ion exchange column chromatography and concentrated by polyvinyl pyrolidone powder at room temperature. The titer of antibodies was estimated using Enzyme Linked Immunosorbent Assay (ELISA).The chickens immunized with Freund's complete adjuvant showed slightly higher titre when compared to bentonite. Inhibition of lethal, edema, haemorrhagic, procoagulant and phospholipase A2 and fibrinolytic activities of snake venoms were determined. The chicken egg yolk antivenom was effective in neutralization of these toxic and enzymatic activities of venom. The median effective dose (ED50) of chicken egg yolk antibodies raised against adjuvant coated venoms showed effective neutralizing venom toxicity when compared to the antibodies raised using bentonite coated venoms.

The article presents the results of experimental evaluation of the effectiveness of new culture substrate developed for the isolation and cultivation of Legionella, the strains isolated from environmental objects in the resort city of Sochi before and during XXII Olympic games. Dense nutrient substrate prepared on the basis of enzymatic hydrolysate of chicken egg yolk and enzymatic hydrolysate of the lung of the pig with additional stimulants allowed saving number of colonies in the earlier stages of the study and storage of the isolated strains during long period of time compared with domestic commercial nutrient substrate.
