E. coli antisera
Clinical relevance
Over the last few decades, a number of new E. coli type pathogens have been identified, e.g. VTEC (verocytotoxin-producing E. coli) and EPEC (enteropathogenic E. coli). This has increased the need for E. coli serotyping, as an important tool in diagnosis, monitoring and testing.
Background
Antisera from SSI Diagnostica are for in vitro use in human, veterinary and food laboratories. All antisera are produced in accordance with internationally recognised methods dating back to the time of Fritz Kauffmann, Ida Ørskov and Frits Ørskov, combined with the knowledge accumulated since then.
All antisera are polyclonal and are produced by immunising rabbits with well-defined reference strains. For antisera, wherever practicable, the reaction is made specific by absorption. All finished products are tested against a large number of strains.
Competence
SSI Diagnostica collaborates closely with the International Escherichia and Klebsiella Centre (WHO) at Statens Serum Institut. Thanks to many years' experience with serotyping, we are able to offer reliable advice, serotyping and molecular typing (see Centre for Microbiological Surveillance & Research).
Quality
SSI Diagnostica's antisera are high quality, CE-marked (except for the E. coli K antisera) and produced in accordance with DS/EN ISO 13485 and DS/ISO 9001. The shelf life is 4 years from the date of production, and a minimum of 2 years from the date of purchase.
Support
Typing: E. coli strains that cannot be typed can be sent to the International Escherichia Centre (WHO), 5 Ørestads Boulevard, DK-2300 Copenhagen S, Denmark, for further investigation. Please contact SSI for prices and carriage.
