Taking into account all these features, the heterogeneity observed within the OspA protein sequences could be a key factor in tissue specificity or in the infection of specific hosts.
However, we lack detailed information on the specificity and stability of different plasmid groups in specific hosts.
Since most insects are monophagous or oligophagous, the distinctness of the odours of different plants often enables them to locate their specific hosts from a distance.
In addition, smaller trees of one species may be less vulnerable to specific hosts when hidden by taller trees of another species (Castagneyrol et al. 2014).
Eurasian common cuckoos, in contrast, are specialists, creating elaborate eggs with matching colours and spots that mimic those of specific hosts.
Because most bacteriophages have very specific hosts, they are assumed to be safe--both when used to treat infections in humans and to treat food products.
Another log format difficulty encountered was that typically only IP addresses were stored, and it was difficult to associate events to specific hosts given that IP addresses could change via DHCP.
Such E. coli-based technology has provided a safe, fast and effective approach to the systematic mining of the information stored in herpesvirus genomes as a result of their intimate co-evolution with their specific hosts for millions of years.
Enzymes are thus obtained by first screening microorganisms and other cells sampled from diverse environments for the desired activities, and then expressing the underlying enzymes in specific hosts – or via modification of existing enzymes using tools of protein engineering (e.g., site-directed mutagenesis).
A spokesman said he couldn't comment on specific hosts.
The protein it encodes has been shown to be required for CTV movement in specific hosts (Dawson, unpublished data).
