Aspergillus niger and other filamentous fungi are widely used in industry, but efficient
genetic engineering of these hosts remains nascent. For example, while molecular genetic …

ABSTRACT A multiresistant clonal Escherichia coli O78: H10 strain qualifying molecularly
as enteroaggregative Escherichia coli (EAEC) was recently shown to be the cause of a …

Uropathogenic Escherichia coli (UPEC) is the primary cause of urinary tract infection (UTI) in
the developed world. The major factors associated with virulence of UPEC are fimbrial …

We investigated the influence of regulatory and pathogenicity island-associated factors
(Hha, RpoS, LuxS, EvgA, RfaH, and tRNA5Leu) on biofilm formation by uropathogenic …

Bacterial biofilm communities are associated with profound physiological changes that lead
to novel properties compared to the properties of individual (planktonic) bacteria. The study …

The invasion of intestinal epithelial cells by the Crohn disease-associated adherent-invasive
Escherichia coli (AIEC) strain LF82 depends on surface appendages, such as type 1 pili and …

Biofilm-dispersal is a key determinant for further dissemination of biofilm-embedded
bacteria. Recent evidence indicates that biofilm-dispersed bacteria have transcriptional …

Background The pagN gene of Salmonella enterica serovar Typhimurium is a PhoP-
regulated gene that is up-regulated during growth within macrophages and in vivo in murine …

Previous studies have established that the expression of Salmonella enterica pathogenicity
island 1 (SPI1), which is essential for epithelial invasion, is mainly regulated by the HilD …

Colonization of the gastrointestinal tract is the first event in Klebsiella pneumoniae
nosocomial infections, followed by colonization of the bladder or respiratory tract or entry …
