E. coli bacteriophages

E. coli bacteriophages

Bacteriophages are viruses used for serotyping of E. coli capsules. It is the only way to serotype capsules which immunologically are closely related to animal cells. Hence, it is not possible to produce polyclonal antibodies against them.

E. coli antisera

SSI Diagnostica is the only company in the world to produce E. coli antisera for full serotyping of all O, K and H antigens. Furthermore,  SSI Diagnostica sells the most frequent bacteriophages and F antigens. We are leading in research and surveillance of E. coli in both the human and veterinary field. Especially within the fields of VTEC, EPEC and ETEC.

Clinical relevance

Over the last few decades, a number of new E. coli 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.

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.
