Colonization, persistence, and tissue tropism of Escherichia coli 026 in conventionally reared weaned lambs
Article Abstract:
An stx-negative Escherichia coli 026 strain of ovine origin was inoculated orally into 6-week-old lambs to monitor the shedding pattern of the 026 strain by serial bacteriological examination of feces. The result data indicate that Escherichia coli 026 readily colonizes 6-week-old lambs, but the sparseness of attaching-effacing (AE) lesions suggests that 026 is well adapted to this host, and mechanisms other than those dependent upon intimin might play a role in persistence.

Novel method for rapid assessment of antibiotic resistance in Escherichia coli isolates from environmental water by use of a modified chromogenic agar
Article Abstract:
A novel method is described and assessed for screening Escherichia coli resistance to antibiotics in environmental samples by using modified Difco MI agar impregnated with selected antibiotics (MI-R). The new method is not only highly reproducible, accurate and precise, but has also reduced the labor and cost, thereby allowing greater analysis and spatial assessment.
