The aim of this study was to classify the CagA into eastern or western type and to determine the number and type of motifs present.
The CagA subtyping was done by PCR and multiplex PCR for eastern/western classification and determination of EPIYA motifs respectively.
All the isolates studied were of the western type, with 70% of the isolates having more than one EPIYA-C motifs. No statistically significant association was found between the presence of CagA and more than one EPIYA-C motifs with the clinical outcome (differentiation status of the tumour).
