However, no one had previously examined the effect of pilus gene expression following attachment of that variety of pilus to its receptor.
Lower type 1 pilus expression was observed in UPEC cells found in a pH 5.5 environment compared to a pH 7.0 environment.
Antibody responses to CPS or pilus proteins were assessed by paired t-test on log-transformed data.
According to flow cytometry, 89% of isolates expressed in vitro [greater than or equal to] 1 pilus type on their surface, most often PI-2a alone or with PI-1.
The acquisition will facilitate Tauriga's access to capital markets while allowing the intrinsic value of Pilus
' technology to be realized through a commercialisation process, it said.
Our results provide evidence that genotyping schemes based on sly, mrp, epf, and pilus cluster genes, although useful in discriminating highly virulent ST1 strains from other groups (8,13,20), are of limited use in differentiating between ST25 and ST28 strains.
Genetic organization and preferential distribution of putative pilus gene clusters in Streptococcus suis.
Tauriga unveiled an agreement to buy Pilus
on 25 November.
Strains that produced a PCR product for PI-2 were further characterized by amplification of pitB, which encoded the pilus
Identification and characterization of genes determining receptor binding and pilus
