Background: To improve urinary tract infection detection, we evaluated the specificity and sensitivity of Loop-mediated isothermal Amplification Method (LAMP) for detection of the in urine samples, for the first time.

Methods: Primers were designed to target the malB gene of . LAMP assay was performed on urine specimens collected from patients with urinary tract infection symptoms.

Results: As expected, LAMP was more specific and sensitive than direct microscopic tests. LAMP assay showed the best detection limit of DNA copies with 1.02 copies.

Conclusion: LAMP method offers several advantages in terms of sensitivity, rapidness and simplicity for detection of infection in urine samples. The LAMP method would be highly suitable for the early detection of the UTIs and also comfort quick diagnosis of UTI in clinical laboratories with limited equipment.

Multiplex digital nucleic acid analysis (NAA) allows the precise quantification of multiple target nucleic acids with single-molecule sensitivity, making it highly appealing for life science research and clinical diagnostics. Nucleic acid-guided endonucleases, such as CRISPR, have demonstrated great potential in digital NAA. However, performing multiplex digital NAA with an endonuclease remains challenging.

Background: Point of need diagnostics provide efficient testing capability for remote or austere locations, decreasing the time to answer by minimizing travel or sample transport requirements. Loop-mediated isothermal amplification (LAMP) is an appealing technology for point-of-need diagnostics due to its rapid analysis time and minimal instrumentation requirements.

Methods: Here, we designed and optimized nine LAMP assays that are sensitive and specific to targeted bacterial select agents including Bacillus anthracis, Francisella tularensis, Yersinia pestis, and Brucella spp.

Staphylococcus pseudintermedius is a global animal pathogen. Traditional identification methods are time-consuming necessitating a more efficient approach. This study validated and enhanced the loop-mediated isothermal amplification (LAMP) technique by integration it with a lateral flow dipstick (LFD) assay for the detection of S.

typically causes mild respiratory infections but can rarely lead to severe complications. We report a case of a 43-year-old immunocompetent male who presented with progressive dyspnea and respiratory failure with bilateral pulmonary infiltrates, refractory to outpatient treatment with azithromycin, ceftriaxone, and levofloxacin. Bronchoscopy revealed multiple white plaques in the trachea and diffuse alveolar hemorrhage.

Background: The loop-mediated isothermal amplification for TB (TB-LAMP) assay is more cost-effective and accessible than the Xpert MTB/RIF assay. This study aimed to evaluate the diagnostic performance of the TB-LAMP assay in individuals with and without HIV infection.

Methods: Patients aged ≥15 years presenting with symptoms of TB were included in the study.
