PCR amplification results for K. pneumoniae and Acanthamoeba detection. A The PCR results for the detection of K. pneumoniae (130Â bp) in water samples from Meichuan Canal, Midori River, Han River, Liuchuan Canal, and Taichung Park Lake. Positive amplification bands are present in samples from the first four sites, while no amplification is observed in Taichung Park Lake. B Showing the PCR results for Acanthamoeba (467Â bp) in the same water samples, indicating positive detection in Midori River, Han River, Taichung Park Lake, and some points in Liuchuan Canal, but no detection in Meichuan Canal
