Furthermore, unintrogressed C. coli clade 3 strains show potential for an extensive respiratory metabolism; possibly reflecting their wide host range and adaptability to novel niches.
Extensive analyses of the genomes of Salmonella strains representing broad host range and host-specific serovars has revealed at least two differences between these serovar types: host-specific serovars have a higher number of pseudogenes and their chromosomes are often rearranged [27], [33], [34], [35], [36].
Only a small proportion of ITS-VTs had broad host ranges and functional group ranges.
The two Elaeagnus isolates, EAN1pec (EAN) and EuI1c (EuI) grow well and rapidly in pure culture, are abundant in soils without host plants, grow rapidly in pure culture and have the most extensive host range that includes Elaeagnaceae, Myricaceae, Casuarinaceae (Gymnostoma), Rhamnaceae as well as Datiscaceae and Coriariaceae where they are present as co-inoculants.
Interestingly, microbes with an extensive host range often pose the greatest risk to humans and are more likely to be categorized as an emerging and reemerging pathogen [32].
Its extensive host range, together with a wide geographic distribution, makes it one of the world's most destructive crop pathogens [ 2]. R. solanacearum has many distinct lineages within a heterogeneous and taxonomically disputed species complex.
This revival is mainly due to the successful use and extensive characterization of VACV as a vaccine during the smallpox eradication campaign, along with the ability to genetically manipulate its large dsDNA genome while retaining infectivity and immunogenicity, its wide mammalian host range, and its natural tropism for tumor cells that allows its use as an oncolytic vector.
The question arises as to why C. lunatus display extensive host-range diversity in a given biota.
These and other differences in immunomodulatory gene families encoded by avipoxviruses may account for the extensive variability in virulence, host range and host interaction [ 11].
