That is, the genes of F. graminearum that are differentially expressed before and after the invasion of this destructive pathogen may be pathogenic genes.
Analysis of the co-infections, however, suggests that P. shigelloides may be pathogenic in the presence of another pathogen.
Although limited data do not indicate that TPMV is a human pathogen, other shrewborne hantaviruses may be pathogenic for humans.
As a result, the selection pressures exerted by resistance differences in co-occurring wild Fov populations may have favoured the selective accumulation of isolates with enhanced pathogenicity – some of which may be pathogenic to cultivated cotton.
Therefore, the differentially expressed genes are possibly related to the interaction between the pathogen and its host, and thereby may be pathogenic genes.
Thus, Clade A organisms may be pathogenic opportunists, in contrast to Clades C/D organisms, which appear to be frank pathogens (Table 1).
These are also good medium for the growth of many microorganisms some of which may be pathogenic to man.
Marine invertebrates are therefore constantly exposed to high concentrations of bacteria, fungi and viruses, many of which may be pathogenic.
The CD4 T cell response to epitope M133 is of particular interest because it may be pathogenic, protective or regulatory, depending upon the physiological setting.
Manure and animal waste deposited on cropland and grazing lands serve as a source of microorganisms, some of which may be pathogenic.
In the current study we observed that CCL3 depletion increased the number of RSV-specific TNF producing CD8 T cells, which may be pathogenic [17], [18].
