THE CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY = JOURNAL CANADIEN DES MALADIES INFECTIEUSES ET DE LA MICROBIOLOGIE MEDICALE 2023; 2023:6654504. [PMID: 37808892 PMCID: PMC10555492 DOI: 10.1155/2023/6654504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 09/09/2023] [Accepted: 09/12/2023] [Indexed: 10/10/2023]
Abstract
Methods Nasopharyngeal swab samples of 300 children with an acute respiratory tract infection were detected by a multiplex PCR-dipstick chromatography assay, and the results were compared with the DNA sequencing and serum IgM antibody assay. Results A multiplex PCR-dipstick DNA assay can specifically detect Mycoplasma pneumoniae and Chlamydia pneumoniae and shows a good specificity, with a minimum detection limit of 10 CFU/mL, respectively. Using DNA sequencing results as the gold standard, the sensitivity, specificity, positive predictive value, and negative predictive value of the multiplex PCR-dipstick DNA chromatography assay for the diagnosis of Mycoplasma pneumoniae were 96.61%, 100%, 100%, and 99.18% respectively, and those of Chlamydia pneumoniae were 95.24%, 100%, 100%, and 99.64% respectively. There was no statistical significance MP and CP diagnosis by the multiplex PCR-dipstick DNA assay and DNA sequencing (MP: P = 0.5; CP: P = 1.0), and the two assays had very high statistical consistency (MP: kappa = 0.979; CP: kappa = 0.974). The positive rate of the multiplex PCR-dipstick chromatography assay was significantly higher than that of the serum IgM antibody assay, with MP (17.7% vs. 13.3%), CP (5.7% vs. 3.3%), and mixed infection of MP and CP (1.3% vs. 0.67%). Conclusions A multiplex PCR-dipstick chromatography assay was successfully established for the joint detection of Mycoplasma pneumoniae and Chlamydia pneumoniae within 2 hours. It is simple, fast, sensitive, accurate, cost-effective with good diagnostic performance, which can be used for small laboratories and point-of-care diagnosis.

Abstract
In this study, we developed a convenient and easy-to-use origin identification method for antler velvets based on a simple DNA extraction technique and single-stranded tag hybridization chromatographic printed-array strip (STH-PAS). The primer sets used to detect Cervus elaphus, Rangifer tarandus, and 12S rRNA did not engage in non-specific reactions such as primer dimer formation. In both the triplex and singleplex assays, the sensitivity was < 1 ng DNA. Moreover, Cervus elaphus DNA could be detected in OTC crude drug products. Although the detection sensitivity resulting from the simplified extraction was slightly lower than that obtained with extraction by conventional methods, the amount of DNA was sufficient even from a small sample. The choice of a triplex or singleplex assay will depend on the purpose of the test. For example, if it is important to determine whether the antler velvet is derived from Cervus elaphus or Rangifer tarandus, a triplex assay is appropriate. If it is necessary to explore whether antler velvet from Cervus elaphus is included in an OTC crude drug product, a singleplex assay using the Cervus elaphus primer set is informative. If it is necessary to explore whether powdered antler velvet includes counterfeit products (from Rangifer tarandus), a singleplex assay employing the Rangifer tarandus primer is appropriate. The singleplex assay detects minor components even at a 1,000:1 ratio. Our study thus demonstrated the utility of a method combining simple DNA extraction with STH-PAS for efficient identification of the origin of antler velvets.

Abstract
Despite the availability of anti-tuberculosis drugs, the treatment of tuberculosis has been complicated by drug-resistant tuberculosis. The early detection of drug resistance makes early treatment possible. However, the available tools are mainly for rifampicin resistance detection, and the existing isoniazid resistance detection method is expensive, highly technical, and complicated, making it unsustainable for use in developing nations. This study aimed to develop a simple, rapid, and low-cost diagnostic kit for isoniazid-resistant tuberculosis using the single-stranded tag hybridization method to target an isoniazid resistance-conferring mutation. Specificity and sensitivity were assessed using DNA extracted from 49 isoniazid-resistant and 41 isoniazid-susceptible Mycobacterium tuberculosis clinical isolates cultured in mycobacterial growth indicator tubes. Positive signals were observed on mutant and wild-type lines with 100% sensitivity and specificity compared with Sanger sequencing results. In contrast, no positive signal was observed for non-tuberculosis mycobacteria. The detection limit of this method was 103 CFU or less. The STH-PAS system for isoniazid-resistant M. tuberculosis detection developed in this study offers a better alternative to conventional phenotypic isoniazid resistance determination, which will be of both clinical and epidemiological significance in resource-limited nations.

Abstract
A dipstick DNA chromatography assay, a single-tag hybridization-printed array strip (STH-PAS), was evaluated for its efficacy to detect dengue virus (DENV). Reverse-transcribed DNA was amplified by PCR, and the amplified DNA was detected using the STH-PAS system. The method was evaluated using stored RNA samples previously identified to carry all 4 serotypes of dengue, chikungunya, and influenza viruses. Clinical performance was also assessed in a prospective study using plasma from 269 febrile cases from the Emergency Department of St. Luke's Medical Center, Quezon City, Philippines, and 30 afebrile normal healthy volunteers. A Taqman real-time PCR (RT-PCR) assay and a rapid Dengue NS1 test, SD Bioline, were used for comparison. The STH-PAS system was more sensitive in detecting dengue infection compared to Taqman RT-PCR. For DENV serotypes 1, 2, and 3, the detection was 1 to 2 dilutions (10-fold) higher, and for DENV serotype 4, the detection was 2-4 dilutions higher. In clinical studies, the STH-PAS system showed 100% sensitivity with 88.9% and 86.6% specificities compared to Taqman RT-PCR and SD Dengue Duo NS1 test, respectively. The STH-PAS system was found to have a superior sensitivity than the Taqman system. Further evaluation of its performance in the field may provide important data to extend its usefulness for surveillance and epidemiological research in outbreak situations.
