“…Similarly, in the mouth of the Lune estuary, changes in Campylobacter numbers correlated with the incoming tide, while those for indicators were associated with effluent from Lancaster’s WWTW upstream of the sampling site (Zainuldin and Jones 1996). During activated sludge sewage treatment, Stelzer et al. (1988) found a significant reduction (94·5%) in campylobacters but not in indicator bacteria.…”

“…Results from several continents have shown that campylobacters are ubiquitous in sewage and that humans and animal waste from abattoirs and animal treatment plants are the major sources (Arimi et al. 1988; Höller 1988; Stelzer et al. 1988, 1991; Jones et al.…”

“…Reports in the literature for the effects of secondary treatment of sewage by trickle filtration, activated sludge and oxidation ponds on the numbers of Campylobacter , show reductions of between 88% and 99% (Stelzer et al. 1988; Stampi et al.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
