Host-Parasite Interrelations: Bacterial Adherence to and Invasion of Epithelial Cells
… or both were compared for colonial opacity, adherence to HeLa cells, and growth under stressful conditions. Both the quantity and type of P.II determined colonial opacity. Gonococcal adherence to HeLa cells correlated with both opacity and P.II content. Environmental factors distinguished …

Effects of Methyl Cellulose on the Cellulolytic Bacterium, Ruminococcus Flavefaciens (Rumen, Anaerobe)
… unable to use methyl cellulose for growth and no bacterial depolymerization of methyl cellulose was observed. Bacterial adherence to cellulose also was inhibited by the cellulose derivatives. Crude mixtures of methylated cellulodextrins (average degree of polymerization (DP) = 9.4 and 8.5) …

The Colonization Strategies of Nontypeable Haemophilus influenzae - Bacterial Colonization Factors and Vaccine Development
… currently known, and identify novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity. We have shown that the NTHi virulence factor Protein E mediates innate immune evasion by …

THE ROLE OF BACTERIAL AMYLOID FIBRILS IN ESCHERICHIA COLI COMPLEMENT RESISTANCE
… more resistant to the complement system. The bacterial amyloid fibril, curli, functions in bacterial adherence and the formation of biofilm. Curli-producing parental and curli-deficient mutant E. coli was compared in its survival to human complement, using in vitro serum sensitivity assays. …

Aderência in vitro de bactérias bucais a diferentes tipos de piercings linguais
… tongue piercings, presenting differences in the bacterial colonization pattern on distinct materials of tongue piercings. The aim was to assess the in vitro adherence of E. corrodens (ATCC 23834) and S. oralis (ATCC 10557) to the surface of tongue piercings made of surgical steel, titanium, …

Molecular and microscopical analysis of pathogenic streptococci - studies on surface proteins interacting with human cells and extracellular matrix
… the spread within its host. Interactions between bacterial surface structures and human proteins might determine the outcome of the infection. Streptococcus pyogenes (S. pyogenes), is a human pathogen mostly causing localized infections of the skin and respiratory tract, but it is also capable of …

Investigating contamination of dental-unit waterline systems and microbial biofilm ecology
… were harboring nosocomial bacteria. Results: The bacterial concentration of the water samples cultured on R2A agar varied significantly (1 × 101 to 4.3 × 106); in surgeries (48%) which met DoH standards and those that failed (52%). A retest of water from surgeries which delivered safe and …

A New Class of Antibiotic That Prevents Drug Tolerance, Persistence, and Resistance By Controlling Emergence of Phenotypes.
<p>The fight against bacterial infections and innovations in antibiotic therapy has never halted throughout human history. However, bacteria have evolved smartly and resistance against practically all conventional antibiotics has been developed. Furthermore, bacteria can form biofilms, which are …

Functional studies of selected actin binding proteins by point mutations and GFP fusions
… disappeared completely upon prolonged bacterial infection. In addition, F-actin structures resembling phagocytic cups were found at the sites of bacterial adherence, suggesting the likelihood of the involvement of the Rho family of small GTPases in the regulation of the actin …

Early pathogenesis of Yersinia ruckeri infections in rainbow trout (Oncorhynchus mykiss, Walbaum)
… traits in vitro that have been associated with bacterial virulence. The General Introduction gives an overview of the micro-organism, Y. ruckeri, and the disease it causes. From this review it is clear that only little information is available about the pathogenesis of Y. ruckeri. Only recently, …
