Qualitative Detection Of E.coli ssp. K99 (F5)

Test applicable to: Cattle 

Sample: Faeces

The FASTest E.coli-K99 Strip contains two unique monoclonal antibodies. One of these monoclonal antibodies is bonded to colloidal gold particles, the second is immobilised in the Test zone of the strip. If the stool sample extract contains K99 main pilar antigens these will form an antigen-antibody complex with the gold particles.

Fast Aetiological Diagnostics 

As this complex migrates along the Test zone of the membrane to the immobilised capture antibody, a pink-purple line is formed indicating a positive test result. The remaining conjugate migrates to a second antibody on the Control zone of the strip forming a second pink-purple line. This indicates the correct performance of the test.

Sample Storage

Samples can be stored for up to 2 days at +2ºC to +8ºC. For longer storage period the faecal suspension can be stored for several months at -20ºC.

Why Test?

Why is it important to test for E.coli K99?

Diarrhoea is a common problem in calves, typically in the first 7 to 14 days of life and is often caused by more than one pathologic agent e.g. Rotavirus, Coronavirus, Cryptosporidium, Salmonella, Giardia and especially enterotoxigenic strains of E.coli (e.g. K99 (F5), (F41). Making a quick diagnosis on-site is difficult and usually based only on clinical signs. Therefore, as most diarrhoea causing agents do not show a clear pathogenic clinical picture especially in cases of mixed infection, it is useful to have a diagnostic tool to detect the causative agent.

Rapid Identification

Using FASTest E.coli-K99 Strip allows the veterinarian to make a rapid and specific diagnosis and to decide quickly on the most appropriate therapy. This rapid identification saves time and can be used to suggest future management strategies to prevent further outbreaks of disease optimising calves health and farm productivity.
