Detection of virulence factors of South African Lactococcus garvieae isolated from rainbow trout, Oncorhynchus mykiss (Walbaum)

Onderstepoort Journal of Veterinary Research, 2018
Lactococcus garvieae is a Gram-positive bacterium that causes mortalities in freshwater and marine fish worldwide and therefore results in severe economic losses in the aquaculture industry. Apart from the apparent integral role of the exopolysaccharide (

Bacterial virulence factors in neonatal sepsis: group B streptococcus

Current Opinion in Infectious Diseases, 2004
Group B streptococcus is a leading cause of neonatal pneumonia, septicaemia and meningitis. Up to one quarter of women in labour are now given intravenous antibiotics to prevent early-onset disease by the organism, a situation that will remain constant until a successful vaccine is available. From a molecular understanding of the pathogenicity of group

Determining the ability of mannoprotein extracted from Saccharomyces cerevisiae to cure some virulence factor genes of some species of pathogenic bacteria isolated from different sources [PDF]

Journal of Bioscience and Applied Research
Background: Bacterial diseases play a major role in wound and burn infections and urinary tract infections, which lead to wound and burn contamination due to the change in the host defense mechanism.

Plants and animals share functionally common bacterial virulence factors

Proceedings of the National Academy of Sciences, 2000
By exploiting the ability of Pseudomonas aeruginosa to infect a variety of vertebrate and nonvertebrate hosts, we have developed model systems that use plants and nematodes as adjuncts to mammalian models to help elucidate the molecular basis of P. aeruginosa pathogenesis.

Nanomaterials Regulate Bacterial Quorum Sensing: Applications, Mechanisms, and Optimization Strategies

Advanced Science
Anti‐virulence therapy that interferes with bacterial communication, known as “quorum sensing (QS)”, is a promising strategy for circumventing bacterial resistance. Using nanomaterials to regulate bacterial QS in anti‐virulence therapy has attracted much

Identification and analysis of genomic islands in Burkholderia cenocepacia AU 1054 with emphasis on pathogenicity islands

BMC Microbiology, 2017
Background Genomic islands (GIs) are genomic regions that reveal evidence of horizontal DNA transfer. They can code for many functions and may augment a bacterium’s adaptation to its host or environment.

Bacterial chitinases and chitin-binding proteins as virulence factors

Microbiology, 2013
Bacterial chitinases (EC 3.2.1.14) and chitin-binding proteins (CBPs) play a fundamental role in the degradation of the ubiquitous biopolymer chitin, and the degradation products serve as an important nutrient source for marine- and soil-dwelling bacteria.

Dual Role of Mechanisms Involved in Resistance to Predation by Protozoa and Virulence to Humans

Frontiers in Microbiology, 2018
Most opportunistic pathogens transit in the environment between hosts and the environment plays a significant role in the evolution of protective traits.

Genomic and Proteomic Analyses of Extracellular Products Reveal Major Virulence Factors Likely Accounting for Differences in Pathogenicity to Bivalves between Vibrio mediterranei Strains

Animals
Vibrio mediterranei, a bacterial pathogen of bivalves, has exhibited strain-dependent virulence. The mechanisms behind the variations in bivalve pathogenicity between V. mediterranei strains have remained unclear.

The Sit-and-Wait Hypothesis in Bacterial Pathogens: A Theoretical Study of Durability and Virulence

Frontiers in Microbiology, 2017
The intriguing sit-and-wait hypothesis predicts that bacterial durability in the external environment is positively correlated with their virulence. Since its first proposal in 1987, the hypothesis has been spurring debates in terms of its validity in ...
