A final point of note is that this work has generated numerous Drosophila strains that express either MSNF9-GFP or MSNF9-DsRed selectively in lamellocytes, within the total population of hemocytes present in immune-challenged or genetically-altered larvae.
The major observations come from studies that sampled phages by performing plaque assays on numerous bacterial strains that were co-isolated from the same marine waters, as in [15].
The development of improved strategies for transgenesis has enabled the generation of numerous mouse strains that allow temporal and spatial labelling of specific subpopulations of cells in the PSU (reviewed by Kretzschmar and Watt, 2012; Blanpain and Simons, 2013; Alcolea and Jones, 2014).
"Holy springs" and "holy water" have been found to contain numerous microorganisms, including strains that are pathogenic to humans [ 51].
The frequency dependent selection is supported by the differences of genetic susceptibility associated to PrP alleles towards the numerous strains of scrapie that prevail in the different subpopulations.
However, there are numerous genetic differences between the strains that may influence both ICOS expression and Th2 differentiation.
Numerous projects have identified M. tuberculosis strains that may represent emerging types and that harbor higher abilities to resist anti-TB drugs and/or BCG vaccination [18] [22].
Furthermore, numerous studies have shown antigenic variation among WNV strains that correlate with geographically distinct regions and restricted bird migratory patterns (16, 17).
In addition, B. thuringiensis, especially those strains that are highly toxic to pests, such as YBT-1520, HD-1, H14, etc, contains numerous plasmids [34] [36].
gattii strains that normally infect immunocompetent individuals.
