A new E. coli O pool antisera system from SSI

The 1st of October SSI Diagnostica introduces sera against 5 new E. coli O serotypes: O182-O186. In combination with the release we also launch a new E. coli O pool system named AA-WW including the four new serotypes.
 
The new O pool system does not only include the four new O serotypes, but has also been improved with regard to reduce cross-reactions between the pools. Based on knowledge from worldwide serotyping, a new pool system has been redesigned, meaning that the pool A does NOT contain the same serotypes as pool AA.
 
The reason to change the combination is a result of new knowledge, the desire to have the best product and to improve costumer satisfaction. As the former E. coli O pool A-W system, the new O pool AA-WW system is based on reducing cross-reactions. Serotypes which are antigenetic alike are grouped in the same pool, minimizing the risk of agglutination in two pools.
 
Even though a test in single O sera reveals the correct serotype, is it both cost and time consuming having to test the strain in single sera from two O pools compared to one O pool.
 
The WHO reference centre at SSI has used this new O pool AA-WW system for two years and is very satisfied with the performance.
 
It will be possible to purchase both the former pool system (O pool A-W) and the new pool system (O pool AA-WW) during 2011. From 1st of January 2012 the O pool system A-W will be discontinued.
 
We know that changing to a new O pool system is time and cost consuming, but in time, the new system will make a profit. As an effort to help in the beginning we offer in 2011 a 25% discount on our new O pool system AA-WW, and on our four new O single antisera.
