Exploring the feasibility of Salmonella Typhimurium-specific phage as a novel bio-receptor Open
The purpose of this study was aimed to isolate a Salmonella Typhimurium-specific phage (KFS-ST) from washing water in a poultry processing facility and to investigate the feasibility of the KFS-ST as a novel bio-receptor for the magnetoela…
View article: Host-Specific <i>Bacteroides</i> Markers-Based Microbial Source Tracking in Aquaculture Areas
Host-Specific <i>Bacteroides</i> Markers-Based Microbial Source Tracking in Aquaculture Areas Open
Various waterborne pathogens originate from human or animal feces and may cause severe gastroenteric outbreaks. Bacteroides spp. that exhibit strong host- or group-specificities are promising markers for identifying fecal sources and their…
