1 C. difficile latex test A Rapid latex agglutination test for the confirmation of C. difficile directly from a selective medium. Clostridium difficile has a well documented role in pseudomembraneous colitis and diarrhoea associated with antibiotics. Evidence has also implicated C. difficile in colitis not induced by antibiotics, exacerbations of chronic inflammatory bowel disease and postoperative diarrhoea. Many laboratories rely on the detection of C. difficile cytotoxin to diagnose infection. However, investigations have shown that the detection of faecal cytotoxin is not always consistent with active infection. This, plus the fact that some laboratories do not have the specialised facilities that are required to detect faecal cytotoxin, has highlighted the continuing need for traditional culture methods. C. difficile provides a simple and specific test for confirmation. Rapid identification confirmed within 2 minutes Easy to use High sensitivity and specificity

2 C. difficile latex test Traditional methods for identification of C. difficile include GLC and cytotoxin detection. However, GLC is expensive in terms of time, equipment and cost per test and the link between presence of cytotoxin and symptoms is inconsistent. The test latex particles in C. difficile are coated with antibodies specific for C. difficile somatic antigens, resulting in a highly specific test with a high predictive negative value. The test maybe be performed from all recognised C. difficile isolation media. The simple-to-use kit gives clear cut results, contains a positive control, has a long shelf-life, and offers the confidence of high sensitivity and specificity.

3 Campylobacter latex test A rapid test for the identification and confirmation of enteropathogenic, thermophilic Campylobacter grown on selective media. Detects Campylobacter from solid selective media Permits the early detection of Campylobacter gastro-enteritis, enabling appropriate therapy to begin sooner Is highly specific so that identification can be reliably formed on the basis of the test alone Campylobacter gastro-enteritis is most prevalent in young children, but outbreaks are also common in adults. In temperate climates the incidence of Campylobacter gastro-enteritis peaks in summer and early autumn, whereas in tropical climates peak incidences may occur in the cooler months. Campylobacter infection may be treated with antibiotics but in the majority of cases, due to the length of time required by traditional detection methods, the acute phase has passed by the time a laboratory diagnosis is communicated to the physician. Rapid identification confirmed within 2 minutes Easy to use High sensitivity and specificity

5 E.coli O157 latex test A rapid test for the identification and confirmation of E. coli serogroup O157 grown on selective solid media. E. coli O157, one of a group of E. coli serotypes known as EHEC are the causative agents of Haemorrhagic colitis (HC), Haemolytic Uraemic Syndrome (HUS) and community acquired diarrhoea. Sorbitol MacConkey medium is the recommended screening agar for E. coli O157, as the strain is unable to ferment sorbitol. However, other sorbitol-negative Gram-negative rods also grow on sorbitol MacConkey agar. As a result of this, a specific rapid confirmation method is required. method and other commercially available latex tests have been shown to suffer from cross reactions with other enteric organisms such as E. hermanii, which antigenically and biochemically resembles E. coli O157, resulting in false positive results. The conventional method for confirmation of E. coli O157 serotypes utilises specific antisera in a standard agglutination test. However, this Rapid identification confirmed within 2 minutes Easy to use High sensitivity and specificity

6 E.coli O157 latex test E. coli O157 is an easy-to-use one step, latex kit which gives results in under two minutes and specifically confirms E. coli O157 directly from the selective agar, even in mixed culture.

9 Listeria latex test A rapid test for the identification and confirmation of Listeria spp. from colonies grown on selective media. Listeria spp. are commonly found in soil and are transferred onto vegetable matter. Foods either derived from vegetables or which are derived from grazing animals and which are exposed to minimal processing i.e. dairy products, are the most common vector for the transmission of Listeria spp. to humans. There are 6 species commonly isolated, including Listeria monocytogenes which has been associated with human disease. L. monocytogenes is an opportunistic pathogen in that it will only cause disease in people with certain predisposing factors such as the immunosuppressed and pregnant women. Rapid identification confirmed within 2 minutes Easy to use High sensitivity and specificity Once isolated on agar plates, colonies resembling Listeria spp. are tested to confirm that they belong to that genus. Other organisms may be isolated from food samples which may resemble Listeria spp. To confirm the presence of Listeria spp. a number of tests are normally used including aesculin hydrolysis, oxidase, catalase, motility (differential at 25 C and 37 C). Microgen Listeria latex was developed as an alternative to this battery of tests. Although individually these tests are inexpensive, they are time consuming to perform. The use of a simple latex agglutination test provides a real-time 2 minute test for the confirmation to genus level of Listeria spp.

10 Listeria latex test Listeria can be used to obtain rapid, presumptive-positive results from selective media thus giving an early indication of a failure in the production process. Where standard methods require it, Listeria can be used to screen colonies before full biochemical identification and can replace traditional agglutinating antibody methods.

15 Staph latex test A rapid test for the identification and confirmation of Staphylococcus aureus colonies grown on selective solid media. Two of the traditional diagnostic tests for S. aureus, the tube and slide coagulase tests, only detect the activity of a characteristic coagulase enzyme. However, these tests can be difficult to interpret and are liable to suffer from false positive results associated with non-specific factors frequently found in plasma. Non-specific coagulation due to other bacterial enzymes may also occur. However, 99% of S. aureus isolates also produce detectable levels of protein A on their surface, a characteristic which can be used to differentiate S. aureus from other species of Staphylococci in which this protein is rare. Staph is a sensitive and specific latex agglutination for the identification of S. aureus which overcomes the problems associated with the traditional tests by detecting both coagulase and protein A, offering rapid and accurate identification of S. aureus in 2 minutes. Staph contains all ancillary reagents needed to complete the test and is suitable for clinical, food and environmental laboratories. Easy to use High sensitivity and specificity Results in 2 minutes

16 Staph latex test Staphylococcus spp. occur as commensal organisms on the mucous membranes and skin of humans. However, Staphylococcus aureus can be responsible for a wide range of pyogenic infections including superficial suppurative lesions, food poisoning and toxic shock, as well as a variety of other conditions. It is therefore one of the most important pathogens regularly encountered in the laboratory. Due to the frequency and importance of Staphylococcal infection a rapid and accurate diagnosis is needed for correct patient management, especially as resistance to numerous common antibiotics has been shown. Also available separately is the Staph latex control reagent (product code M43CCE), helping to reinforce the accuracy and reliability of the Staph rapid test.
