Abstract: The present invention provides a method of identifying a subject having a haplotype in a toll-like receptor 4 gene of the subject that is associated with an increased risk of invasive mold infection in a recipient of a transplant from the subject, comprising genotyping the subject for the presence of particular single nucleotide polymorphisms or haplotypes in the toll-like receptor 4 gene of the subject, wherein the detection of said single nucleotide polymorphism(s) and/or haplotype(s) identifies the subject as having a single nucleotide polymorphism and/or haplotype associated with an increased risk of invasive mold infection in a recipient of a transplant from the subject.

Abstract: The present invention provides method of identifying a subject as having an increased risk of developing a Gram negative bacterial infection and/or as having an increased risk of mortality, comprising genotyping the subject for the presence of particular alleles of the lipopolysaccharide binding protein gene, wherein the presence of said allele(s) identifies the subject as having an increased risk of developing a Gram negative bacterial infection and/or of having an increased risk of mortality.
