Environmental survival of antibiotic resistant organisms (AROs) such as Vancomycin resistant Enterococci (VRE), methicillin resistant Staphylococcus aureus (MRSA) and sporulating organisms such as Clostridium difficile has been suspected to play a role in nosocomial transmission of these pathogens [ 1, 2].
In addition, our study demonstrates the presence of multiple independent adaption events of LAB species to different survival habitats, indicating that further analyses of more genes from representatives of additional LAB species are needed in order to reveal the molecular mechanisms underlying the adaptation of LAB species to various environmental survival niches.
The authors of the above review concluded that different factors may significantly affect assessment of the predominant HAV strains, including sample collection strategies and a small sampling size, environmental survival of viral strains and complex patterns of HAV circulation in the world [ 2].
Comparative studies between MNV and FCV have been published; however, they have focused either on the environmental survival of the viruses [11], [13] or compared the activity of chemicals against FCV and MNV in in vitro settings [14] [16].
However, deletion of the Mmp13 gene dramatically reduced articular chondrocyte apoptosis following MLI, potentially because the more intact cartilage in Mmp13 Col2ER mice may provide chondrocytes with environmental survival cues.
The greater frequency of environmental detection of MRSA compared with ESBL- E. coli may reflect more intense shedding of MRSA or better environmental survival.
Given that strains of many LAB species occur in a multitude of ecological niches, further analyses of more genes and functional assays of additional LAB species are needed to reveal the molecular mechanisms underlying the adaptation of LAB species to various environmental survival niches.
A colonization factor links Vibrio cholerae environmental survival and human infection.
Deep understanding of niches will lead researchers to an understanding of how deprivation of certain environmental survival cues also in the face of chemo could kill these cells.
For some human pathogenic fungi the determinants of virulence (virulence factors) appear to have been selected for environmental survival and function in mammalian virulence more by accident or happenstance, than design.
This article considers how anticipated futures of space travel and environmental survival are materialized in the project to engineer the minimal biosphere capable of reliably sustaining human life: a human/microbe association with the fewest possible species.
