Colonization dynamics of oro-gastrointestinal microbes critical to infant health
… an infection. In Chapter 4, the mechanism of autoaggregation in the neonatal pathogen, Cronobacter sakazakii ATCC 29544 (wild-type) is described. Upon isolation of two independent nonautoaggregating clonal variants, two unique single nucleotide polymorphisms in the flagella proteins, FlhA and …

Investigating the molecular mechanisms of the interactions between Lactobacillus reuteri strains and intestinal mucus
… and their role in mediating mucus binding and autoaggregation ability of L. reuteri strains, as determined by flow-cytometry and in vitro mucus binding assays with recombinant and native proteins. Finally a quantitative proteomic approach, stable isotope labelling with amino acids in cell …

Isolation and characterisation of bifidobacteria populations in infants in the Khomas region, Namibia
… good cell surface hydrophobicity and autoaggregation. Bifidobacteria present in stool samples are contemplated to have potential applications in food safety owing to the high antagonistic activities they have exhibited and may have probiotic applications in the dairy and food …

Biochemistry and functional analysis of exopolysaccharide production in Lactobacillus johnsonii
… loss of the EPS layer increased the adhesion and autoaggregation properties of L. johnsonii in vitro but EPS layer was found to be protective against several antimicrobials and environmental stress conditions. Additionally EPS layer was shown to be important on physicochemical properties and …

Role of VimA in Cell Surface Biogenesis in Porphyromonas gingivalis
… to play a role in hemolysis, hemagglutination, autoaggregation, posttranslational protein modification, and LPS biogenesis. Though significant progress has been made in characterizing this gene, much remained unsolved prior to this work, especially as it relates to the molecular mechanisms and …

Pathogenesis and clinical significance of AIDA-I-positive E. coli in diarrhea of pigs
… adherence to HeLa cells, enhanced bacterial autoaggregation and significant biofilm formation by AIDA-I+ strains, when compared to AIDA-I- strains.Second, 110 F4 negative E. coli isolates from problematic cases of diarrhea in pigs were subjected to multiplex polymerase chain reaction (M-PCR) …

Study of apoptotic deletion mediated by Bifidobacterium longum with construction of recombinant strains for Serpin encoding gene and phenotypes comparison in a pig cell model
… for their adhesion properties using adhesion and autoaggregation assays. These features are considered necessary to select a probiotic strain. The three strains named B12, B18 and B2990 resulted respectively: “strong adherent”, “adherent” and “non adherent”. Then, bacteria were incubated with …
