EPS II-dependent autoaggregation of sinorhizobium meliloti planktonic cells
(Springer, 2010-04-11)
Planktonic cells of Sinorhizobium meliloti, a Gram-negative symbiotic bacterium, display autoaggregation under static conditions. ExpR is a LuxR-type regulator that controls many functions in S. meliloti, including synthesis ...
Effects of culture conditions on the growth and auto-aggregation ability of vaginal Lactobacillus johnsonii CRL 1294
(Wiley Blackwell Publishing, Inc, 2005-10-06)
Aims: To evaluate the effects of different physico-chemical factors on the growth and auto-aggregating ability of vaginal Lactobacillus johnsonii CRL 1294. Methods and Results: L. johnsonii CRL 1294 was cultivated in ...
A positive correlation between bacterial autoaggregation and biofilm formation in Native Sinorhizobium meliloti isolates from Argentina
(American Society for Microbiology, 2012-06)
Sinorhizobium meliloti is a symbiotic nitrogen-fixing bacterium that elicits nodule formation on roots of alfalfa plants. S. meliloti produces two exopolysaccharides (EPSs), termed EPS I and EPS II, that are both able to ...
Cell autoaggregation, biofilm formation, and plant attachment in a sinorhizobium meliloti lpsB mutant
(American Phytopathological Society, 2018-10)
Bacterial surface molecules are crucial for the establishment of a successful rhizobia-legume symbiosis, and, in most bacteria, are also critical for adherence properties, surface colonization, and as a barrier for defense. ...
First report of the distribution of Locus of Adhesion and Autoaggregation (LAA) pathogenicity island in LEE-negative Shiga toxin-producing Escherichia coli isolates from Argentina
(Academic Press, 2018)
© 2018 Elsevier Ltd Shiga toxin-producing Escherichia coli (STEC) are important foodborne pathogens that can cause severe disease. The ability to adhere to epithelial cells is an important virulence trait and pathogenicity ...
Distribution of Locus of Adhesion and Autoaggregation and hes Gene in STEC Strains from Countries of Latin America
(Springer, 2020-06)
Shiga toxin-producing Escherichia coli (STEC) are zoonotic food pathogens associated with foodborne diarrheal illness, hemorrhagic colitis, and complications such as hemolytic uremic syndrome (HUS). The ability to adhere ...
Phenotypic surface properties (aggregation, adhesion and biofilm formation) and presence of related genes in beneficial vaginal lactobacilli
(Wiley Blackwell Publishing, Inc, 2014-12)
Aims: To evaluate the phenotypic expression of auto-aggregation, adhesion to mucin and biofilm formation of lactobacilli isolated from human vagina and the presence of related genes. Methods and Results: Seven different ...
Expression of stress-related proteins in Sediminibacterium sp. growing under planktonic conditions
(Wiley, 2015-04-01)
Aggregation is a common trait of bacteria in natural and engineered biological systems. Microbial aggregates, such as flocs, granules, and biofilms, are spatially heterogeneous environments. It is generally observed that ...
Draft Genome Sequences of Type Strain Sediminibacterium salmoneum NJ-44T and Sediminibacterium sp. C3, a Novel Strain Isolated from Activated Sludge
(American Society for Microbiology, 2014-01)
The genus Sediminibacterium comprises species present in diverse natural and engineered environments. Here, we report for the first time the genome sequences of the type strain Sediminibacterium salmoneum NJ-44T (NBRC ...
Selected Lactobacillus strains isolated from sugary and milk kefir reduce Salmonella infection of epithelial cells in vitro
(Wageningen Academic Publishers, 2016-04)
The isolation of potentially probiotic strains and the subsequent study of their properties are very important steps to gain insight in the health benefits ascribed to sugary and milk kefir. The aim of the present study ...
