anti-TRH Toxin (V.parahemolyticus) antibody rabbit polyclonal IgG
Information
Code:64-015Many Vibrio parahemolyticus isolated as a cause of food poisoning produce toxin called hemolysin and this is the main cause of illness. The hemolysin of V. parahemolyticus mainly interacts with an intestinal tract or the heart produces diarrhea by enterotoxicity and also there are severe cases of making a patient die by cardiotoxicity. Two kinds heat-resistant hemolysin (TDH thermostable direct hemolysin) and heat-resistant toxin related hemolysin (TRH TDH-related hemolysin) are known as hemolysins of V. parahemolyticus. Among these TDH is known for many years and has been studied more extensively. In order to distinguish whether it is the V. parahemolyticus that producesTDH samples are grown on the Agatsuma medium (blood agar which is addedwith mannitol) and judged by whether a hemolysis is observed or not. This hemolysis was one of the examining methods which is called Kanagawa phenomenon to judges whether it is pathogenic V. parahemolytica. However it became clear that the food poisoning by the V. parahemolyticus of Kanagawa-phenomenon negativity was discovered and this organism did not produce TDH but it produced TRH. Moreover since the Kanagawa phenomenon sensitivity is not so high the immunological technique employing antibody against toxin is used together for the judgment of pathogenicity of V. parahemolyticus.TRH is the heat labile toxin protein of molecular weight 21.1 kDa (189 aa). Homology of TDH (21.3 kDa 189 aa) with TRH is about 60% (reference 1 and 2) and shows partial antigenic similarities. Susceptibility of the blood cells of various animals to TRH differs greatly and TRH shows more than 100 times in rabbit skin capillary permeability activity than TDH.
