Molecular Mechanisms Involved in Escherichia coli K1 and Haemophilus influenzae Type a Blood-Brain Barrier Impairment
… caused by different pathogens, including Escherichia coli K1 (E. coli K1) and Haemophilus influenzae type a (Hia). During E. coli K1 meningitis, CNS cells release pro-inflammatory mediators, while the bacterium promotes the association between Vascular Endothelial Growth Factor Receptor 1 …

Function and Environmental Regulation ofkpsF, the First Gene of the Region One Operon of Escherichia Coli K1
… environmental stimulus currently known to affect K1 capsule expression. Capsule is maximally expressed at body temperature (37$\sp\circ$C or 98.6$\sp\circ$F), but is turned off at temperatures commonly encountered in the external environment, below about 26$\sp\circ$C. Expression of the first gene …

Untersuchungen zu intrazellulären Folgereaktionen von Neisseria meningitidis und Escherichia coli K1 in HBMEC (human brain microvascular endothelial cells)
… wie auch beim Erreger neonataler Meningitiden E. coli K1 wird eine O-Acetylierung des Kapselpolysaccharids beobachtet. Die biologische Bedeutung der O-Acetylierung der Sialinsäure wurde in Infektionsassays mit einem nicht acetylierten E. coli K1 Stamm und einer isogenen konstitutiv acetylierten …

The capsular polysaccharide of Actinobacillus pleuropneumoniae serotype 5A: role in serum resistance and characterization of the genetic basis for expression
… of anti-CP IgG, encapsulated A. pleuropneumoniae K17 was killed in precolostral calf serum (PCS) but not in normal serum used as a complement source. In contrast, two capsule-deficient mutants were killed in normal serum. The CP of A. pleuropneumoniae contributed to serum-resistance by limiting …
