“…Numerous studies describe viral communities in different habitats (Suttle, 2005;Gino et al, 2007;Andersson and Banfield, 2008); however, few have described these communities in humans (Breitbart et al, 2008;Nakamura et al, 2009;Willner et al, 2009Willner et al, , 2010Reyes et al, 2010).…”

Viruses are the most abundant known infectious agents on the planet and are significant drivers of diversity in a variety of ecosystems. Although there have been numerous studies of viral communities, few have focused on viruses within the indigenous human microbiota. We analyzed 2 267 695 virome reads from viral particles and compared them with 263 516 bacterial 16S rRNA gene sequences from the saliva of five healthy human subjects over a 2- to 3-month period, in order to improve our understanding of the role viruses have in the complex oral ecosystem. Our data reveal viral communities in human saliva dominated by bacteriophages whose constituents are temporally distinct. The preponderance of shared homologs between the salivary viral communities in two unrelated subjects in the same household suggests that environmental factors are determinants of community membership. When comparing salivary viromes to those from human stool and the respiratory tract, each group was distinct, further indicating that habitat is of substantial importance in shaping human viromes. Compared with coexisting bacteria, there was concordance among certain predicted host–virus pairings such as Veillonella and Streptococcus, whereas there was discordance among others such as Actinomyces. We identified 122 728 virulence factor homologs, suggesting that salivary viruses may serve as reservoirs for pathogenic gene function in the oral environment. That the vast majority of human oral viruses are bacteriophages whose putative gene function signifies some have a prominent role in lysogeny, suggests these viruses may have an important role in helping shape the microbial diversity in the human oral cavity.

“…Human health impacts of microorganisms such as chironomid eggs (Senderovich et al 2008) have also been discussed for their potential effects on public health and the environment. WHO discusses additional concerns for bacteriophage species, F-RNA, and somatic coliphages 10 3 -10 4 plaque-forming units/mL (Gino et al 2007), and somatic coliphage (phiX-174) and F-specific RNA phage (MS2) (Benyahya et al 1998).…”

Oxidation pond for municipal wastewater treatment

et al. 2015

This literature review examines process, design, and cost issues related to using oxidation ponds for wastewater treatment. Many of the topics have applications at either full scale or in isolation for laboratory analysis. Oxidation ponds have many advantages. The oxidation pond treatment process is natural, because it uses microorganisms such as bacteria and algae. This makes the method of treatment cost-effective in terms of its construction, maintenance, and energy requirements. Oxidation ponds are also productive, because it generates effluent that can be used for other applications. Finally, oxidation ponds can be considered a sustainable method for treatment of wastewater.

“…Phages which infect E. coli, Salmonella, Bacteroides and Enterococcus faecalis among others have been isolated directly from human sewage samples or polluted waters. [26][27][28][29][30] A study to determine the occurrence and concentrations of somatic coliphages (phages which infect via the cell membrane) and Bacteroides fragilis phages in the stools of a The aim of this review is to shed light on the potential role that phages may play in human intestinal physiology by examining the literature with respect to phage effects on microbial population dynamics, bacterial chromosome evolution and the host immune system. We consider the phage-host dynamic which occurs in the healthy intestine where microbes may be nutritionally deprived in the lumen.…”
