Gonorrhea Diagnostic

Neisseria gonorrhoeae is one of the most common bacterial sexually transmitted infections (STI). Diagnosis depends on standard nucleic acid amplification testing (NAAT), which is impracticable in most low-resource settings, where the prevalence of this STI is highest. Consequently, such areas utilize syndromic management, which misses a high proportion of cases and leads to antibiotic overuse, contributing to the troubling rise of resistance to the commonly prescribed ciprofloxacin, cefixime and ceftriaxone antibiotics for the treatment of N. gonorrhoeae infections. A specific, highly sensitive and cost-effective lateral flow assay is disclosed that utilizes CRISPR-Cas orthologs, multiplex SHERLOCK technology and isothermal amplification via recombinase polymerase amplification (RPA) for the rapid detection of antibiotic resistance to ciprofloxacin, cefixime and / or ceftriaxone at the point of care. This approach has the potential to increase treatment efficacy in the field and mitigate the spread of antibiotic resistance.
