Molecular characterization of extraintestinal and diarrheagenic Escherichia coli blood isolates

Virulence, 2022
Pathogenic E. coli strains can be classified into two major groups, based on the presence of specific virulence factors: extraintestinal pathogenic E. coli (ExPEC) and diarrheagenic E. coli (DEC).

Crown rust pathotypes determined on oats in the Czech Republic from 2004 to 2006 and reaction to oat cultivars

Czech Journal of Genetics and Plant Breeding, 2008
The incidence of oat crown rust (Puccinia coronata var. avenae Fraser et Ledingham) pathotypes was recorded in the Czech Republic in 2004-2006. The virulence of collected 79 monopustule oat crown rust isolates was assessed on 23 differentials.
