Genotyping of Virulence Factors of Uropathogenic Escherichia coli by PCR

open access: yesNovelty in Biomedicine, 2015
Background: Escherichia coli is the most causative agent of urinary tract infections (UTIs). Apart from all human infectious diseases, UTI have a high prevalence and in most cases, Escherichia coli is a dominance bacterium which can cause pyelonephritis ...

Virulence factors in Serratia marcescens: cell-bound hemolysin and aerobactin.

open access: yesBrazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologica, 1993
1. A total of 60 nosocomial isolates of Serratia marcescens were screened for the presence of markers related to virulence, i.e., cell-bound hemolysin and production of siderophore aerobactin. 2. No aerobactin-producing strains were found, and the incidence of cell-bound hemolysin was 97%. 3.

Additional file 7: of Tracking key virulence loci encoding aerobactin and salmochelin siderophore synthesis in Klebsiella pneumoniae

open access: yes, 2018
Phylogenetic relationships between the predicted amino acid sequences encoded by aerobactin (iuc) and salmochelin (iro) locus sequence types. Each tip represents a translated amino acid sequence for an aerobactin sequence type (AbST, in a) or salmochelin

Genetic Determinants of Antagonistic and Growth-Stimulating Activity of Pantoea pleuroti

open access: yesТехника и технология пищевых производств
Cereals are crucial to food security, but intensive agrochemical farming depletes soil ecosystems and increases environmental risks. In this regard, microbial biological control agents hold great promise.
