Abstract
The present invention relates to novel strains of lactic acid bacteria, more specifically, novel strains of Lactobacillus reuteri, capable of utilizing ethanolamine. This characteristic makes it possible for the bacteria to compete for the same substrate as pathogenic ethanolamine-utilizing pathogens, thereby presenting an effective means to combat infections resulting from such pathogenic bacteria. There is also provided a method of selecting further ethanolamine-utilizing lactic acid bacteria, as well as other methods and uses involving said novel strains and other ethanolamine-utilizing lactic acid bacteria.
Claims15
A method for treating or reducing the risk of developing a condition or disorder caused by or related to an ethanolamine-utilizing pathogen in a subject in need thereof, said method comprising administering to the subject an effective amount of the lactic acid bacteria capable of utilizing ethanolamine produced by
- (a) culturing lactic acid bacteria capable of utilizing ethanolamine in a culture medium;
- (b) adding to the culture medium of (i) a first amount or concentration of ethanolamine at a first point in time and growing said culture;
- (c) optionally adding to the culture of (ii) a second amount or concentration of ethanolamine at a second point in time and growing said culture;
- and
- (d) retrieving the lactic acid bacteria from said culture medium.
A method for treating or reducing the risk of developing a condition or disorder caused by or related to an ethanolamine-utilizing pathogen in a subject in need thereof, the method comprising administering to the subject an effective amount of a lactic acid bacteria that has been induced by ethanolamine during growth.
A method for treating or reducing the risk of developing a condition or disorder caused by or related to an ethanolamine-utilizing pathogen in a subject in need thereof, said method comprising administering to the subject an effective amount of a Lactobacillus reuteri strain capable of utilizing ethanolamine.
