To investigate the evolution of plasmids in their hosts, comparisons have been made at the levels of GC content [ 28, 29] and dinucleotide composition [ 30, 31], but not from the viewpoint of replication strand asymmetry.
A host of comparison sites claim to make this easy, while the energy companies are keen to lure new customers.
We then focus on the likely journey of Clostridium difficile through the GI tract of a healthy host in comparison to an immunocompromised host.
The closely related MAC display slight genomic differences depending on their host and comparison of these differences has the potential to identify host specific pathogenicity factors, leading to improved diagnosis and treatment.
The results obtained in this study indicate that natural populations of A. ervi coming from different hosts in the field exhibit important differences in infectivity on their natal host in comparison with non-natal hosts, although this pattern was not observed for all the parasitoid populations nor in all behavioral variables studied.
Parasitoids obtained from the aphid hosts S. avenae, A. pisum-alfalfa race, and A. pisum-pea race showed a greater infectivity on their natal host in comparison with that shown on non-natal hosts, but only for some of the behavioral variables studied (e.g., time to first sting).
In the case of a host-parasite comparison, M will pair hosts and parasites.
In old leaves, leaf volumes were up to 3-fold higher when parasitizing halophytic hosts in comparison with non-halophytic hosts.
The "Daily Show" host drew comparisons to Sen. Lindsey Graham's gloomy reaction to the State of the Union, while a city in his part of the country was collapsing due to some precipitation.
Mites are small and unable to migrate the relatively long distances between mushrooms without assistance; the insect hosts, in comparison, are large and can transfer the mites between their preferred feeding habitats.
