Construction of vaccine from Lactococcus lactis bacteria using Aeromonas hydrophila virulent Aerolysin gene
In this study the forward and reverse primers were designated to amplify the segments (~250 bps and ~650 bps) of the gene coding domains 1 and 4 of aerolysin of Aeromonas hydrophila. These two domains are involved in pathogenesis of the aerolysin gene. Sequences for two restriction enzymes, Pst I and Hind III, were included in the forward and reverse primers respectively. These restriction enz...
متن کاملCloning of EprA1 gene of Aeromonas hydrophila in Lactococcus lactis
Bacterial-based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. Developments in genetic engineering have given Gram-positive lacticacid bacteria (LAB) the advantage of being used as a host expression system for antigen delivery to inducethe immune response. A fragment containing the full length of the “eprA1” ...
متن کاملThe Construction of a Probiotic Lactic Acid Bacterium Expressing Acid-Resistant Phytase Enzyme
The use of probiotics engineered to express specific enzymes has been the subject of considerable attention in poultry industry because of increased nutrient availability and reduced cost of enzyme supplementation. Phytase enzyme is commonly added to poultry feed to improve digestibility and availability of phosphorus from plant sources. To construct a probiotic with potential of phytate degrad...
متن کاملInduction of Immunogenic Response in BALB/c Mice by Live and Killed Form of Recombinant Lactococcus lactis Displaying EG95 of Echinococcus granulosus Immunogenic Response in BALB/c Mice
Background: CE is a zoonotic parasitic infection caused by Echinococcus granulosus worldwide and is associated with economic losses among livestock animals. EG95 is an immunogenic antigen from the E. granulosus. Lactococcus lactis has been prested as a safe vehicle for antigen delivery. The goal of this study was to design a novel L. lactis strain displaying EG95 as a vaccine delivery system. M...
متن کاملافزایش تولید نایسین در بیوراکتور با کشت همزمان Lactococcus lactis و Yarrowia lipolytica
نایسین اولین نگهدارنده غذایی تایید شده FDA است که در مقیاس صنعتی توسط Lactococcus lactis subsp. lactisتولید میشود. برای کاهش اثر منفی اسید لاکتیک تولید شده در متابولیسم Lactococcus lactis subsp. lactisبر روی تولید نایسین، کشت توام این باکتری با Yarrowia lipolytica استفاده شده است. در این پژوهش برای اولین بارLactococcus lactis به همراه Y. lipolytica در تخمیر بسته با استفاده از بیوراکتور آزمای...
