Thus, the sample cells used here were microscopically pure but it can not rule out the possibility of being contaminated with intracellular organisms (symbionts) or externally invisible virus-like organisms (though its probability is less than a millionth of that of finding in the original sea water due to the repeated dilution).
The possibility of GM organisms escaping and invading wild populations is no small worry.
In the study project 'Ocean Farming Sustainable exploitation of marine organisms', we explore the possibilities of marine organisms to fulfill needs, such as safe and healthy food, industrial (raw) materials and renewable energy in a sustainable way.
The isolation of high numbers of pathogenic organisms that are associated with surgical site infection from the surfaces of these devices highlights the possibility of transmitting such organisms to patients' limbs immediately before surgery, thus increasing the risk of postoperative surgical site infection.
Similarly, the US National Organic Program foresees only the possibility of using biological organisms for plant protection.
One of the major causes of inappropriate initial antimicrobial therapy was the ignorance of the possibility of antimicrobial-resistant organisms causing the infections.
Mutation rate variability is a key theme in current discussions of the need for an extended evolutionary synthesis [14], [15] under the name of "the evolution of evolvability", the tantalizingly recursive possibility that the ability of organisms to evolve is itself a trait, or spectrum of traits, under evolutionary control [16] [19].
During 2008, as an investigation of the possibility of persistent excretion of organisms, additional samples were collected 5 times.
These are of particular relevance to pulmonary infection in CF. Possible hazards must be considered when evaluating the potential therapeutic use of bacteriophages, such as the possibility of the infected organism acquiring virulence traits from the phage, as has been demonstrated recently [ 96].
Issues such as the possibility of non-human dispersal of organisms, stability and survival of non-indigenous organisms in vivo, the sensitivity, reproducibility and specificity of the PCR process (and particularly primer design) and the sampling regime employed must all be considered in detail.
