Enterococci are common, commensal members of gut communities in mammals and birds,
yet they are also opportunistic pathogens that cause millions of human and animal infections …

Natural genetic transformation is the active uptake of free DNA by bacterial cells and the
heritable incorporation of its genetic information. Since the famous discovery of …

The oxic realms of freshwater and marine environments are zones of high prokaryotic
mortality. Lysis by viruses and predation by ciliated and flagellated protists result in the …

In order to study the size dependency of grazing and growth rates in zooplankton, data were
collected from laboratory studies in the literature, covering both limnic and marine …

Fecal microorganisms can enter water bodies in diverse ways, including runoff, sewage
discharge, and direct fecal deposition. Once in water, the microorganisms experience …

The small average cell size of in situ bacterioplankton, relative to cultured cells, has been
suggested to be at least partly a result of selection of larger-sized cells by bacterivorous …

The susceptibility of coliform bacteria and bacterial pathogens to free chlorine residuals was
determined before and after incubation with amoebae and ciliate protozoa. Viability of …

Hidden problems, buried deep in the pipe networks of water distribution systems, are very
serious potential threats to water quality. Microbial Quality of Water Supply in Distribution …

We examined grazing of marine viruses and bacteria by natural assemblages and cultures
of phagotrophic nanoflagellates. Ingestion rates were determined using fluorescently …

Rates of grazing on bacteria or phytoplankton by protists in natural waters may be estimated
by evaluating the average rate of particle ingestion by specific components of the protistan …
