While the suitability of jack pine as a major host for MPB and the ability of these trees to survive during outbreak of MPB are unknown, host range expansion of MPB from lodgepole pine into jack pine forests has heightened the risk of increased environmental impact of the MPB epidemic.
In contrast to neutral glycans, Sia with a negative charge is a major receptor and a host range determinant of influenza viruses [25].
Thus component exchange possibly drives diversification of species into strains, which is not surprising since DNA-B components play a major role in host range determination [ 43].
Dear Editor, Verticillium wilt, caused by the soil-borne fungus Verticillium dahlia Klep., poses a major threat to a broad host range of more than 400 plant species, including economically important cotton, and causes serious loss of lint yield in China, the USA and may other countries (Bell, 1992; Bejorano-Alcazar et al., 1995; Zhang et al., 2012).
C. pecorum is a useful model to investigate adaptation to different niches since it is a major pathogen with a broad host range and tissue tropisms [ 11– 13].
The corn earworm is a major agricultural pest, with a large host range encompassing corn and many other crop plants.
Cyst nematodes are a group of plant pathogens each with a defined host range that cause major losses to crops including potato, soybean and sugar beet.
Among these strains, E. granulosus sensu stricto has a broad geographical distribution with a wide host range and is the major causative agent of human cystic echinococcosis.
Influenza A viruses have a wide host range for birds and mammals, posing a major threat to animal health as well as a zoonotic threat to humans [ 1].
Assemblage B, one of the two major assemblages causing human giardiasis, has a broad host range, including cattle, sheep, pigs, horses, dogs, cats, and rabbits [ 2].
