Tn5-induced mutations affecting virulence factors of Bordetella pertussis [PDF]

Infection and Immunity, 1983
Transposon Tn5 was used to isolate mutants of Bordetella pertussis. Strains with Tn5 insertions were screened for loss of virulence-associated factors, including filamentous hemagglutinin, hemolysin, and pertussis toxin. Several mutants deficient for hemolysin production were obtained.

BipA Is Associated with Preventing Autoagglutination and Promoting Biofilm Formation in Bordetella holmesii. [PDF]

PLoS ONE, 2016
Bordetella holmesii causes both invasive and respiratory diseases in humans. Although the number of cases of pertussis-like respiratory illnesses due to B. holmesii infection has increased in the last decade worldwide, little is known about the virulence

The Eukaryotic Host Factor 14-3-3 Inactivates Adenylate Cyclase Toxins of Bordetella bronchiseptica and B. parapertussis, but Not B. pertussis

mBio, 2018
Bordetella pertussis, Bordetella bronchiseptica, and Bordetella parapertussis share highly homologous virulence factors and commonly cause respiratory infections in mammals; however, their host specificities and disease severities differ, and the reasons

Bordetella pertussisVirulence Factors Affect Phagocytosis by Human Neutrophils [PDF]

Infection and Immunity, 2000
ABSTRACTThe interaction between human neutrophils and wild-typeBordetella pertussisor mutants expressing altered lipopolysaccharide or lacking virulence factors—pertussis toxin, adenylate cyclase toxin, dermonecrotic toxin, filamentous hemagglutinin (FHA), pertactin, or BrkA—was examined.

Dermonecrotic toxin and tracheal cytotoxin, putative virulence factors of Bordetella avium [PDF]

Infection and Immunity, 1988
We examined Bordetella avium for virulence factors common to Bordetella pertussis, including pertussis toxin, filamentous hemagglutinin, adenylate cyclase, dermonecrotic toxin, and tracheal cytotoxin. B. avium produced a dermonecrotic toxin and a tracheal cytotoxin. The dermonecrotic toxin of B.

Genome-wide analysis reveals loci encoding anti-macrophage factors in the human pathogen burkholderia pseudomallei K96243 [PDF]

, 2010
Burkholderia pseudomallei is an important human pathogen whose infection biology is still poorly understood. The bacterium is endemic to tropical regions, including South East Asia and Northern Australia, where it causes melioidosis, a serious disease ...

T3SS chaperone of the CesT family is required for secretion of the anti-sigma factor BtrA in Bordetella pertussis

Emerging Microbes and Infections, 2023
Bordetella pertussis is a Gram-negative, strictly human re-emerging respiratory pathogen and the causative agent of whooping cough. Similar to other Gram-negative pathogens, B.

Heterogeneity in ess transcriptional organization and variable contribution of the Ess/Type VII protein secretion system to virulence across closely related Staphylocccus aureus strains [PDF]

, 2014
The Type VII protein secretion system, found in Gram-positive bacteria, secretes small proteins, containing a conserved W-x-G amino acid sequence motif, to the growth medium.

Molecular evolution of the two-component system BvgAS involved in virulence regulation in Bordetella. [PDF]

PLoS ONE, 2009
The whooping cough agent Bordetella pertussis is closely related to Bordetella bronchiseptica, which is responsible for chronic respiratory infections in various mammals and is occasionally found in humans, and to Bordetella parapertussis, one lineage of

Isolation, Antimicrobial Resistance Phenotypes, and Virulence Genes of Bordetella bronchiseptica From Pigs in China, 2018–2020

Frontiers in Veterinary Science, 2021
Bordetella bronchiseptica is a leading cause of respiratory diseases in pigs. However, epidemiological data of B. bronchiseptica in pigs particularly in China, the largest pig rearing country in the world is still limited.
