Description of intervention(s) / exposure
The overall study period will be for 8 months. The trial will consist in obtaining faecal samples from an hospital laboratory which will then be sent to us for testing. The first phase will concist in an initial screen of the samples for VTEC using molecular methods. If the molecular scree is positive then the second phase will consist in isolating and characterising the VTEC from the faecal sample.

Outcomes
Primary outcome [1] 258976 0
Establish occurence of non-O157 VTEC in New Zealand.The first phase of this project will look at optimising
(a) molecular-based methods for the detection of non-O157 STEC from clinical samples, and
(b) culture-based methods for the isolation of non-O157 STEC.
The second phase of this project will apply these methods to the screening of clinical samples obtained from a hospital
laboratory.

At the end of the clinical trial (at the end of the 8 months)
Secondary outcome [1] 265165 0
From the results obtained from the clinical trial we will be able to draw recommendations in the form of a final report as to which methods to use for the detection and isolation of non-O157 VTEC.
