The phrase "are associated with pathogenicity" is correct and usable in written English.
It can be used in scientific or medical contexts to describe a relationship between certain factors and the ability to cause disease.
Example: "Certain genetic mutations are associated with pathogenicity in various bacterial strains."
Alternatives: "linked to pathogenicity" or "connected to disease-causing ability".
In many pathogenic bacteria, a fraction of repetitive sequences are associated with pathogenicity genes.
Four of the residues (H15R, N23S, T27I, and H75L) are associated with pathogenicity in mice by residue effect, and six residues (8, 15, 23, 27, 69, and 75) are associated with pathogenicity by host effect.
These five residues are associated with pathogenicity of the viruses in mice by residue effect meaning that observed residue variations affected the pathogenicity of the viruses in mice, and four PB2 residues (67, 152, 199, and 508) are associated with pathogenicity by the host effect.
Most of these residues are associated with pathogenicity in mice by residue effect (S/T7L and E227G in NS1 and S/T7L and S70G in NEP) and by host effect (227 in NS1 and 70 in NEP).
There are a few ORFs (004, 113, 182, 194, 211; table 1 and supplementary table S2, Supplementary Material online) in the RB49/phi1 genomes that are associated with pathogenicity islands, plasmids, or integrons, which could be suspected to be involved.
The hlyA and cnf-1 genes showed a positive relationship with the B2 group; also they are associated with pathogenicity island PAI IIJ96, and the iutA gene is associated with pathogenicity island PAI ICFT073 as well as with hlyA and pap operon [ 8, 19, 34– 34].
Morphologic transition from the yeast to the hyphal state in Candida albicans is associated with pathogenicity of this human pathogen.
Microbial enzymes, such as catalases, involved in defense against oxidative stress have been associated with pathogenicity and virulence in certain human fungal pathogens.
