Salmonella, a gram-negative facultative rod-shaped bacterium, is found in human and animal intestines. Most people get infected with salmonella by eating contaminated food such as raw meat, infected poultry and seafood, raw eggs, and contaminated fruits and vegetables. Salmonella infection causes diseases and conditions such as typhoid, paratyphoid, and food poisoning. Major symptoms of salmonella infection include diarrhea, fever, dehydration, and abdominal cramps that usually occur within 8 to 72 hours after ingesting contaminated food. Most people recover without treatment. However, sometimes diarrhea and dehydration may become severe and the patient may need medical attention. Elderly people, infants, and people who have a weak immune system due to disease such as AIDS, sickle cell disease, malaria, and corticosteroids get affected more easily by salmonella infection. The salmonella testing procedure includes detection and isolation, and confirmation and identification of the bacteria. In the detection and isolation stage, animal feces and water sources are tested for the bacteria. Moreover, large number of food ingredients and food products are routinely tested by the food industry, especially meat products, eggs, and dairy products for the detection of salmonella in these items. Salmonella testing methods include traditional and rapid detection methods. It takes 3 to 5 days to detect the presence of salmonella in a source using the tradititional methods, while the rapid detection method takes up to 48 hours to the detect the presence of salmonella. Request TOC (desk of content material), Figures and Tables of the report: http://www.persistencemarketresearch.com/toc/4214 The global salmonella testing market is categorized based on various technologies used to detect the bacteria, food type, and end user. Based on technology, the report covers traditional and rapid technologies.

We evaluated the robustness of loop-mediated isothermal amplification (LAMP) of DNA for bacterial diagnostic applications. Salmonella enterica serovar Typhi was used as the target organism and compared with a real-time quantitative PCR (qPCR) for testing assay performance and reproducibly, as well as the impact of pH and temperature stability. This isothermal amplification method appeared to be particularly robust across 2 pH units (7.3-9.3) and temperature values (57-67°C). The detection limit was comparable to that observed using optimized home-brew qPCR assays. The specificity of the amplification reaction remained high even at temperatures markedly different from the optimal one. Exposing reagents to the ambient temperature during the preparation of the reaction mixture as well as prolonging times for preparing the amplification reaction did not yield false-positive results. LAMP remained sensitive and specific despite the addition of untreated biological fluids such as stool or urine that commonly inhibit PCR amplification. Whereas the detection of microorganisms from whole blood or a blood-culture medium typically requires extensive sample purification and removal of inhibitors, LAMP amplification remained more sensitive than conventional qPCR when omitting such preparatory steps. Our results demonstrate that LAMP is not only easy to use, but is also a very robust, innovative and powerful molecular diagnostic method for both industrialized and developing countries. © 2011 Federation of European Microbiological Societies.

Major acute phase proteins (APPs) have proven diagnostically useful in dogs, cats and horses with routine use facilitated by commercially available automated heterologous assays. An automated assay applicable across all three species would highly facilitate further dissemination of routine use, and the aim of this study was to validate an automated latex agglutination turbidimetric immunoassay based on monoclonal anti-human serum amyloid A (SAA) antibodies for measurement of canine, feline and equine SAA. Serum samples from 60 dogs, 40 cats and 40 horses were included. Intra- and inter-assay imprecision, linearity and detection limit (DL) were determined to assess analytical performance. To assess clinical performance, equine and feline SAA measurements were compared with parallel measurements using a previously validated automated SAA assay in a method comparison setting, and by assessing overlap performance of canine SAA in healthy dogs and diseased dogs with and without systemic inflammation.Intra- and inter-assay CVs ranged between 1.9-4.6% and between 3.0-14.5%, respectively. Acceptable linearity within a clinically relevant range of SAA concentrations was observed for all three species. The DL was 1.06. mg/L. Method comparison revealed acceptable agreement of the two assays measuring feline and equine SAA, and the overlap performance of canine SAA was acceptable. The tested assay measured SAA in canine, feline and equine serum with analytical and overlap performance acceptable for clinical purposes so improving practical aspects of clinical APP application. The monoclonal nature of the antibodies suggests strong, long-term inter-batch performance stability. © 2012 Elsevier Ltd.

Loop-mediated isothermal amplification (LAMP), a newly developed gene amplification method, combines rapidity, simplicity, and high specificity. Several tests have been developed based on this method, and simplicity is maintained throughout all steps, from extraction of nucleic acids to detection of amplification. In the LAMP reaction, samples are amplified at a fixed temperature through a repetition of two types of elongation reactions occurring at the loop regions: self-elongation of templates from the stem loop structure formed at the 3'-terminal and the binding and elongation of new primers to the loop region. The LAMP reaction has a wide range of possible applications, including point-of-care testing, genetic testing in resource-poor settings (such as in developing countries), and rapid testing of food products and environmental samples.

Hepatitis B virus (HBV) infections are sometimes overlooked when using commercial kits to measure hepatitis B virus surface antigen (HBsAg) due to their low sensitivities and reactivities to mutant strains of various genotypes. We developed an ultrasensitive bioluminescent enzyme immunoassay (BLEIA) for HBsAg using firefly luciferase, which is adaptable to a variety of HBsAg mutants, by combining four monoclonal antibodies with a polyclonal antibody against HBsAg. The measurement of seroconversion panels showed trace amounts of HBsAg during the early infection phase by the BLEIA because of its high sensitivity of 5 mIU/ml. The BLEIA detected HBsAg as early as did PCR in five of seven series and from 2.1 to 9.4 days earlier than commercial immunoassay methods. During the late infection phase, the BLEIA successfully detected HBsAg even 40 days after the disappearance of HBV DNA and the emergence of antibodies against HBsAg. The HBsAg BLEIA successfully detected all 13 recombinant HBsAg and 45 types of HBsAg mutants with various mutations within amino acids 90 to 164 in the S gene product. Some specimens had higher values determined by the BLEIA than those by a commercial chemiluminescent immunoassay; this suggests that such discrepancies were caused by the dissociation of preS1/preS2 peptides from the particle surface. With its highly sensitive detection of low-titer HBsAg, including various mutants, the HBsAg BLEIA is considered to be useful for the early diagnosis and prevention of HBV infection because of the shorter window of infection prior to detection, which facilitates early prediction of recurrence in HBV-infected individuals.

Background: White blood cell (WBC) count and C-reactive protein (CRP) level are the most common markers of inflammation. There is a growing need for point-of-care testing (POCT) of WBC and CRP, and more advances in convenient devices are required. We developed an analyzer-free POCT system for measuring WBC and CRP using a low volume blood sample. Methods: The POCT-WBC is based on the granulocyte esterase assay, while the POCT-CRP is based on the immunochromatographic assay. These kits were examined for precision as well as correlation with currently used popular commercial automated assays. The correlations were clinically analyzed in children with acute infection (n = 62; mean age 4.2. y). The correlations regarding the monitoring of values were further examined in several follow-up subjects. Results: The POCT-WBC and POCT-CRP kits demonstrated good precision. POCT-WBC exhibited a significantly close correlation with those of the control assay (r = 0.94, p. <. 0.05). The results of POCT-CRP also exhibited a significantly close correlation with those of the control assay (r = 0.94, p. <. 0.05). In the follow-up study, the results of the respective kits were similar to those of the control assays. Conclusions: The POCT-WBC and POCT-CRP are promising tools for assessing infection in clinical practice. © 2014 Elsevier B.V.
