mune and allergic responses that were similar to those generated by both Pinto and Tendergreen beans. Furthermore, the responses to the non-transgenic peas were related to a crossreactive response to pea lectin and the MCE Company AV-951 consumption of transgenic, non-transgenic and bean seed meals did not accentuate allergic responses to another non-cross-reactive allergen. Our results are at odds with the previous study in which mice developed allergic responses to aAI peas but not to beans. It is possible that the source of the mice and their normal baseline diets may play a role. The mice used in the Austrian experiments were purchased from Charles River Germany and maintained in a pathogen-free mouse room. The mice used in the Australian studies originated from the Jackson Laboratory and were bred at The John Curtin School of Medical Research by sibling mating for at least 70 generations in an SPF Unit. These mice were maintained in the Australian Phenomics Facility by inbred sibling mating. The health status of the mice in Austria revealed that there were no pathological or commensal organisms or antibodies detected. These data are not available for the mice used in Australia. There are no data regarding gut microbiota in either mouse house. The diet in Austria was from SSNIFF and the Australian diet was produced by Gordon��s Specialty Stock Feeds P/L in New South Wales. The most obvious differences between the two diets are in the sources of the dietary TMS protein, fatty acid type, level of soluble fibre and level of vitamin supplementation. While any or all of these dietary differences could influence immune responses, it is unlikely that they could cause a differential response to pea and bean constituents. Another possibility could be that aAI peas and proteins used in the studies differed, but the aAI peas and the nontransgenic controls were from the same batches of seeds produced at CSIRO. Because the previous study showed that only aAI peas caused allergic responses in mice, we were surprised that not only did Tendergreen bean and Pinto bean induce allergic responses, but so did the non-transgenic peas. We discovered that pea lectin antibodies are generated upon consumption of peas and that this antibody crossreacts with aAI. In conclusion, although our studies show th
