Synbiotic composition for treatment of infections in allergic patients

A method of treating infection in an allergic subject, consisting of administering to a subject suffering from microbial infection a composition comprising:

• (i) between 10 and 20 wt % free amino acids based on dry weight of the total composition;
• (ii) 15 to 75 mg per gram dry weight of the composition of a soluble indigestible oligosaccharide mixture of:
• (a) short chain fructooligosaccharide with an average degree of polymerisation from 2 to 6, and
• (b) long chain fructooligosaccharide with an average degree of polymerisation of at least 7,
• wherein the weight ratio short chain fructooligosaccharide:long chain fructooligosaccharide is at least 1, and
• wherein the composition does not comprise (a) uronic acid oligosaccharide and (b) soluble indigestible oligosaccharides other than the short and long chain fructooligosaccharides;
• and
• (iii) at least 1.0×107 cfu live Bifidobacterium breve per gram dry weight of the composition,
• wherein administration of the composition leads to fewer incidence of infections than without administration.
