Future studies should investigate the large geographic distribution of AGV2 and monitor the variants, the host range
, and the associated diseases.
cactorum in Argentina (roughly 23[degrees]53'S to 40[degrees]48'S; 58[degrees]38'W to 66[degrees]10'W) was surveyed from Aug 2007 to Mar 2014 for the presence of cactus-feeding moth larvae to determine the field host range
The serologic data yielded by both assays are consistent with the known epidemiology of AI virus in wild birds and published reports of host range
based on virus isolation and RT-PCR.
For example, the relatively narrow host range
of most phages which caused many of the early attempts at phage therapy to fail can be overcome by isolating phages that have a broad host range
within the species being targeted.
A host range
study is in progress to assess the pathogenicity of these two newly found Fusarium species on different crops commonly grown in rotation with dry bean.
The ten extended articles here follow suit in their descriptions of research in foot-and-mouth disease viruses, the molecular biology of pestiviruses, arteriviruses, coronavirus replication and interaction with the host, hendra and nipah virus, the molecular mechanisms of pathogenesis and host range
in avian influenza, molecular dissection of the bluetongue virus, molecular biology of porcine circoviruses, molecular biology of animal herpesviruses, and the African swine fever virus.
Although it is clear that one of the principle mechanisms involved in the emergence of new viral diseases is a change in the host range
, there are many gaps in our knowledge about the mechanism(s) involved and how zoonotic viruses establish themselves in humans.
Koi herpesvirus is attractive as a biological control agent as overseas studies suggest that it has a very limited host range
, infecting only carp.
What we know about the rust is that it is very specific and has a narrow host range
," said Tim Butler, supervisor of the state Department of Agriculture's Noxious Weed Control Program.
solanacearum exist, each with a different host range
Although both avian hosts are perching birds found in the order Passeriformes, they belong to different families (Sittidae and Emberizidae), which suggest the possibility of a wide host range
for this helminth parasite.
However, outlying regions of the genome did vary, and it was here that genes governing features such as host range
, infectiousness and evading the immune system were located.
