Serotype of isolates as determined by direct agglutination method (see Materials and Methods).
FAFLP genotypes were designated following cluster analysis (see Fig. 2) as cluster B to H followed by clone number or, for cluster A complex, as clusters A-1 to A-6 followed by clone type (designated by letters a to f).
A-UG designated to a characterized FAFLP genotype which is unclustered within the cluster A complex.
UG designated to a characterized FAFLP genotype which is unclustered within this study.
Indicates the C. coli strain, which exhibited a diverse and unclustered genotype.
