Because cholera toxin (CT) is responsible for most of the symptoms induced by |i|Vibrio cholerae|/i| infection, detection of CT is critical for diagnosis of the disease. In this study, we constructed an immunochromatographic test strip for detection of CT (CT-IC) with polyclonal antibodies developed against purified recombinant whole CT protein. The detection limit of the CT-IC was 10 ng/mL of purified recombinant CT, and it could detect the CT in culture supernatant of all 15 toxigenic |i|V. cholerae|/i| isolates examined, whereas no false-positive signal was detected in all 5 nontoxigenic |i|V. cholerae|/i| isolates examined. The specificity of the CT-IC was examined with recombinant heat-labile toxin (LT), which shares high homology with CT, and it was revealed that the minimum detection limit for LT was 100 times higher than that for CT. In addition, |i|lt|/i| gene-positive enterotoxigenic |i|Escherichia coli|/i| (ETEC) was examined by CT-IC. The false-positive signals were observed in 3 out

A test strip for conducting a lateral flow assay for detection of an analyte in a sample that contains cells and fluid is provided, as well as methods for making and using the test strip. This test strip is commercially usable, for example, in a diagnostic device at a point of care for detection of analytes in whole blood.
Although lateral flow assays (LFAs) are currently being used in some point-of-care applications (POC), they cannot still be extended to a broader range of analytes for which higher sensitivities and lower detection limits are required. To overcome such drawbacks, we propose here a simple and facile alternati

Chromatographic immunoassay employing a specific binding pair member and a label conjugate which delineates a border whose distance from one end of the chromatograph relates to the amount of analyte present. By combining the label conjugate and sample in a solution and immunochromatographing the solution, or employing a combination of enzymes, one enzyme being the label and the other enzyme affixed to the chromatographic support, the position of the border defined by the label can be related to the amount of analyte in the sample solution. Preferably, an immunochromatograph is employed having both a specific binding pair member and an enzyme affixed to the support. A sample is chromatographed and the amount of analyte is determined by (1) contacting the chromatograph with a second enzyme conjugated with a specific binding pair member which binds to the chromatograph in proportion to the amount of analyte bound to the chromatograph, or (2) including the second enzyme conjugate with said sample, resulting
A diagnostic test kit for detecting an analyte residing in a test sample is provided. The kit employs a lateral flow device that contains a membrane. A metering channel is formed in the membrane that is capable of delivering a controlled volume of the test sample to a detection zone upon initiation of the assay. Such a metering channel is particularly effective for embodiments in which the test sample has a relatively low volume, such as less than about 100 microliters, in some embodiments from about 0.5 to about 25 microliters, and in some embodiments, from about 1 to about 10 microliters. For example, whole blood drops obtained from patients with a lancet typically have a volume of less than about 3 microliters. Despite their low volume, the present inventors have discovered that the blood drops may still be accurately analyzed for the presence of an analyte using lateral flow detection techniques.
A diagnostic method and associated test kit for detecting an analyte residing in a test sample is provided. The kit includes a housing, and a membrane disposed within the housing having a detection region and a collection region. A blood sample meter is provided having a first end for absorption of a blood sample, a filtering section adjacent to the first end that filters red blood cell components from the blood sample, and a storage section adjacent to the filtering section that receives plasma or serum from the filtering section. An opening in the housing is sized for insertion of the sample meter into the housing such that the storage section of the sample meter is disposed in fluid communication with the collection region of the membrane. The plasma or serum is transferred from the storage section of the sample meter to the collection region of the membrane for subsequent migration to the detection region.

A cross-sectional study using 99 serum samples of dogs from southern Chile was conducted to determine the diagnostic utility of a rapid immunochromatography assay for the detection of Leptospira specific IgM antibodies as screening test and as a potential aid in the diagnosis of leptospirosis in animals with and without clinical suspicion of the disease. The Microscopic Agglutination Test (MAT) was used as reference assay. Anti-Leptospira antibodies were detected in 37.3% of the dogs with MAT. Using the immunochromatography test, specific IgM antibodies were found in 13.1% of sampled dogs. The sensitivity of the rapid test as screening assay was 29.7% (95% Confidence Interval=16.4-47.2) and the specificity was 96.7% (95% Confidence Interval=87.8-99.4). 40.0% of the canines with clinical suspicion of leptospirosis and 37.1% of dogs without clinical signs were serological reactors to MAT, but none of MAT reactive dogs with clinical suspicion tested positive in the rapid test.

Group B Streptococcus (GBS; Streptococcus agalactiae) is a leading cause of serious neonatal infections. The Centers for Disease Control and Prevention recommends GBS screening for all pregnant women during the 35th to 37th weeks of gestation. Although GBS screening has been performed mainly by the culture-based method, it takes several days to obtain a reliable result. In this study, we developed a rapid immunochromatographic test (ICT) for the detection of GBS-specific surface immunogenic protein in 15 min using an overnight enrichment culture. The ICT was prepared using two anti-Sip monoclonal antibodies. This ICT was able to detect recombinant Sip levels of 0.5 ng/ml, or about 10(6) CFU/ml of GBS cells, in tests with 9 GBS strains of different serotypes. The cross-reactivity test using 26 species of microorganism showed no detectable false-positive result. Reactivity of the ICT with 229 GBS strains showed one false-negative result that was attributable to the production of truncated Sip. Among 260
A total of 90 stool sample was collected from patients with gastroenteritis to detect adenovirus antigen among diarrhea cases. They were tested by general stool examination (GSE), rapid immunochromatographic test and Enzyme Linked Immunosorbent Assay (ELISA). GSE showed that adenovirus gastroenteritis infection resulted in non-bloody diarrhea, the existence of RBCs in 7% and Pus in 37% of the samples, Entamoeba histolytica trophozoite and cyst were seen in 3% and 2% of the samples respectively. The rapid test showed that 21% of samples were positive for rotavirus, 8% for adenovirus and 3% for astrovirus. Meanwhile, the ELISA test showed that adenovirus was positive in 9% of the samples. These findings established the evidence that adenovirus is significantly the second viral agent that cause gastroenteritis among children after rotavirus. Furthermore, it must be stated that rapid diagnostic methods are important for detection of adenovirus infection.. ...
