EHEC is capable of inducing life threatening illnesses, particularly in people with immune deficiency, young children and the elderly. Although the most common cause of EHEC is E. coli O157, other serotypes, such as O26, O45, O103, O111, O121 and O145, are also relatively frequent causes of infection. Typical symptoms are severe abdominal pain and diarrhoea, which is initially watery but often becomes bloody. E. coli are gram-negative, non sporulating, facultative anaerobic bacilli. Amongst the pathogenic E. coli, Verotoxin-forming strains (STEC or VTEC) have gained importance in recent years. The group of enterohaemorrhagic E. coli (EHEC) with its highly pathogenic serovar O157:H7 strain is particularly interesting in this respect. The main sources of infection are contaminated, raw or insufficiently heated foods of animal origin, such as meat and dairy products. The reservoir for EHEC is the gut of ruminants. Microorganisms can enter food during the processing of meat and dairy products if hygienic conditions are inadequate. The drastic increase in the incidence of food contamination caused by E. coli O157 demands reliable and rapid methods of detection. Innovative, rapid tests make screening for pathogenic organisms easier. Complete test sets for the detection of pathogens and toxins. The one-step format reduces the possibility of errors during handling. In addition to tests for the most common cause of infection, E. coli O157, there exits a 24-H screening protocol for VTEC, including E. coli O104:H4, based on Rapidcult™ E. coli enrichment combined with detection using Duopath® Verotoxins.

Supplier: MEMMERT

This steriliser complies with all relevant standards and regulations for medical products and guarantees reliable programme sequences, irrespective of the load and chamber volume. Especially due to the SetpointWAIT function the validation of this hot air steriliser is possible anytime. The SetpointWAIT function ensures that the programme is only continued when the setpoint temperature has been reached. Precisely maintaining the sterilisation time and thus completely killing off even highly resistant microorganisms is therefore guaranteed at all times, irrespective of the sterilisation load and chamber volume. This feature can also be used with additional, freely positionable Pt100 temperature sensors. In this case, sterilisation only begins when the setpoint temperature has been reached at all measurement points – that is, in the load. For the special application of depyrogenisation, the hot-air steriliser is absolutely ideal. The SF models are equipped with single display.
