Nucleotide sequence of two fimbrial major subunit genes, pmpA and ucaA from canine-uropathogenic Proteus mirabilis strains
Article Abstract:
The N-terminal amino acid sequences of the fimbrial subunits produced by Proteus mirabilis strains causing urinary tract infection (UTI) are identical to that of a urinary cell adhesin. Two genes ucaA and pmpA are present in the subunits and the 56% amino acids of UcaA protein are same as that of the fimbrial subunits produced by the bovine enterotoxigenic Escherichia coli while the PmpA protein is similar to a protein produced by other UTI causing E. coli. The Pmp fimbriae helps the cell to adhere to the intestinal tract rather than the urinary tract.

Aeromonas trota strains, which agglutinate with Vibrio cholerae O139 Bengal antiserum, possess a serologically distinct fimbrial colonization factor
Article Abstract:
The colonization factor of Aeromonas trota strains were characterized because colonization by pathogens is the initial step of the infectious disease process. Pili of A. trota strain 1220 was purified and characterized, revealing the subunit protein's molecular mass to be about 20 kDa and the pl to be 5.4. The subunit pilin's N-terminal amino acid sequence was found to be similar to those of the pilins from other A. pili already studied. Results suggest that the A. trota strain's pilus is a novel colonization factor of Aeromonas spp.

A novel approach for the construction of a Campylobacter mutant library
Article Abstract:
Research was conducted to examine a novel approach for the construction of mutant libraries of Campylobacter jejuni strain 81116 using natural transformation. DNA uptake using natural transformation in C. jejuni was observed to be highly efficient when DNA sequences identical to the incoming DNA are already present in the acceptor cell. Results demonstrate that the method is the best available and may also be applicable for exploring the genetics of Campylobacter spp. and related organisms which are also naturally transformable.
