FIG 3.

Analytical specificity of the colorimetric c-LAMP. Visual detection with cresol red (pink = negative and yellow = positive). Samples are described as follows: (1, 2) Isolates of hAdV40 and hAdV41 from fecal extract confirmed by Sanger sequencing of the hexon gene; (3) hAdV7; (4) hAdV21; (5) hAdV1; (6) hAdV2; (7) hAdV3; (8) hAdV4; (9) hAdV5; (10) hAdV6; (11) hAdV 8; (12) Shigella flexneri and Shigella sonnei; (13) Salmonella enteritidis; (14) hAdV40/41 negative fecal extract. Neg – negative control amplification without DNA; Pos – positive control amplification, 10⁵ copies/mL.
