Abstract

Curable sexually transmitted infections (STIs) caused by the bacteria Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are widespread globally. These infections are particularly dangerous for female patients, causing pelvic inflammatory disease, infertility, and increased risk for HIV acquisition. Vaginal self-swab sampling can improve access to STI screening but is still subject to treatment delays due to centralized processing. A low-cost point-of-care (POC) device capable of detecting these bacteria from a self- or clinician-collected vaginal swab could address this delay and allow for more timely treatment. In this work, vaginal swab material from patients infected with CT or NG required a filtration step before lysis and loop mediated isothermal amplification (LAMP) detection on the UbiNAAT device. We have shown a simple, low-cost sample preparation method that supports rapid DNA detection from NG and CT on our POC UbiNAAT platform. Here we show time-stamped photographs taken using a filtered cell phone camera to show fluorescence from SYTO82, an intercalating dye which binds to double stranded nucleic acids generated by LAMP amplification of target pathogen DNA. We also show quantified fluorescence data recorded by an optical thermocycler system (BioRad CFX or CFX-Opus), which also indicates the amplification of target pathogen DNA.
