Measuring of free endotoxin in alum-precipitated vaccine of haemorrhagic septicaemia by limulus amebocyte lysate test
Haemorrhagic septicaemia (HS) vaccine which is prepared in Razi Institute is used in endemic areas ofIran. Aluminum-hydroxide gel was used as adjuvant for preparing this vaccine. Post-vaccinal shock reactionswere the main complaint after use of this vaccine. In a previous study, we could improve the vaccine byalum-precipitation Pasteurella multocida cells and removing the liquid phase. In this ...
متن کاملEndotoxin neutralization by lactoferricin-derived antimicrobial peptides
Lipopolysaccharide (LPS), if released from the outer membrane of Gram-negative bacteria during blood stream infections, is causative for sepsis and septic shock syndrome, and thus is denominated endotoxin. Septic shock is characterized by an massive activation of human immune cells by LPS to produce proinflammatory cytokines leading to an overbording systemic response of the immune system and c...
متن کاملEvaluation of the Limulus amebocyte lysate and recombinant factor C assays for assessment of airborne endotoxin.
As a potent inflammatory agent, endotoxin is a key analyte of interest for studies of lung ailments in domestic environments and occupational settings with organic dust. A relatively unexplored advance in endotoxin exposure assessment is the use of recombinant factor C (rFC) from the Limulus pathway in a fluorometric assay. In this study, we compared airborne endotoxin concentrations in laborat...
متن کاملPurification and characterization of an endotoxin-binding protein with protease inhibitory activity from Limulus amebocytes.
Using a lipopolysaccharide affinity column and ion exchange chromatography, a 12-kDa protein has been purified from Limulus amebocytes. In solid phase binding assays, the radiolabeled protein binds specifically to lipopolysaccharide (LPS) with a Kd value on the order of 10(-7) M. A cDNA coding for this protein has been isolated and sequenced. The amino acid sequence deduced from the cDNA indica...
متن کاملNeutralization of endotoxin toxicity in chick embryos by antibiotics.
Rifkind, David (University of Colorado Medical Center, Denver), and John D. Palmer. Neutralization of endotoxin toxicity in chick embryos by antibiotics. J. Bacteriol. 92:815-819. 1966.-Three cationic cyclic polypeptide antibiotics, polymyxin B sulfate colistin sulfate, and tyrocidine hydrochloride, were shown to neutralize endotoxin lethality in chick embryos. The neutralizing potency of these...
