Virioplankton: Viruses in Aquatic Ecosystems
TLDR
Novel applications of molecular genetic techniques have provided good evidence that viral infection can significantly influence the composition and diversity of aquatic microbial communities, supporting the hypothesis that viruses play a significant role in microbial food webs.

DNA sequence of both chromosomes of the cholera pathogen Vibrio cholerae
TLDR
The V. cholerae genomic sequence provides a starting point for understanding how a free-living, environmental organism emerged to become a significant human bacterial pathogen.

Microbial degradation of hydrocarbons in the environment.
TLDR
Rates of biodegradation depend greatly on the composition, state, and concentration of the oil or hydrocarbons, with dispersion and emulsification enhancing rates in aquatic systems and absorption by soil particulates being the key feature of terrestrial ecosystems.

Emerging marine diseases--climate links and anthropogenic factors.
TLDR
A dramatic global increase in the severity of coral bleaching in 1997-98 is coincident with high El Niño temperatures, which climate-mediated, physiological stresses may compromise host resistance and increase frequency of opportunistic diseases.

Effects of Global Climate on Infectious Disease: the Cholera Model
TLDR
The cholera model provides a template for future research on climate-sensitive diseases, allowing definition of critical parameters and offering a means of developing more sophisticated methods for prediction of disease outbreaks.

Survival strategies of bacteria in the natural environment.
TLDR
The heterotrophic plate count has come under increasing criticism because it is inefficient, at best, for enumerating viable bacteria present in marine and estuarine systems.

Viable but nonculturable stage of Campylobacter jejuni and its role in survival in the natural aquatic environment
TLDR
In all cases, increasing temperature of cultivation resulted in decreased recoverability on laboratory media, due possibly to an increased metabolic rate, as analyzed by CO2 evolution in the presence of radiolabeled glutamate.

A communal catalogue reveals Earth’s multiscale microbial diversity
TLDR
A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project is presented, creating both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity.

Climate and infectious disease: use of remote sensing for detection of Vibrio cholerae by indirect measurement.
TLDR
Confirming the hypothesis that V. cholerae is autochthonous to the aquatic environment and is a commensal of zooplankton, i.e., copepods, when combined with the findings of the satellite data analyses, provide strong evidence that cholera epidemics are climate-linked.

Critical Factors Influencing the Occurrence of Vibrio cholerae in the Environment of Bangladesh
TLDR
The results of environmental sampling and analysis of the environmental and clinical data have revealed significant correlations of water temperature, water depth, rainfall, conductivity, and copepod counts with the occurrence of cholera toxin-producing bacteria (presumably V. cholerae).
