Detection of potentially pathogenic Arcobacter spp. in Bangkok canals and the Chao Phraya River

The management of pathogenic bacteria in waterways is a public health issue. Here, we investigated the concentrations of potentially pathogenic bacteria, Arcobacter spp. and Campylobacter spp., and Escherichia coli, by quantifying species-specific genes in surface water samples from canals and the C...
