Farm environments: Reservoir for Multidrug‐Resistant and Virulent Escherichia coli in Bangladesh [PDF]

Int J Microbiol
Farm environments, especially dairy and poultry farms, are the major sources of multidrug‐resistant (MDR) pathogenic Escherichia coli. At present, knowledge regarding the prevalence of MDR E. coli, phylogroup, and pathotype in various farm environments of Bangladesh is inadequate.

Presence of eaeA sequences in pathogenic and nonpathogenic Escherichia coli strains isolated from weaned rabbits [PDF]

Journal of Medical Microbiology, 1994
Seventy-one Escherichia coli strains isolated from diarrhoeic weaned rabbits from different areas of France were tested for the presence of DNA sequences specific for the EPEC, EHEC, DAEC and EAggEC strains and 16 of them were tested for pathogenicity in animal experiments.

Distinct binding properties of eaeA-negative verocytotoxin-producing Escherichia coli of serotype O113:H21 [PDF]

Infection and Immunity, 1994
Infection of humans with verotoxin-producing Escherichia coli (VTEC) O113:H21 is associated with clinical features comparable to those associated with infection with attaching and effacing VTEC strains including those of serotype O157:H7. We have shown previously that the adhesion phenotype of VTEC O157:H7 is influenced by the presence of a homolog of ...
