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

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.

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

Severe pertussis infection in infants less than 6 months of age: clinical manifestations and molecular characterization [PDF]

, 2017
We conducted a study to determine the main traits of pertussis among unimmunized infants less than 6 months of age. From August 2012 to March 2015, 141 nasopharyngeal aspirates (NPAs) were collected from infants with respiratory symptoms attending 2

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.

Bacillus anthracis edema factor substrate specificity: evidence for new modes of action [PDF]

, 2012
Since the isolation of Bacillus anthracis exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only.

Comparative genomics of the classical Bordetella subspecies: the evolution and exchange of virulence-associated diversity amongst closely related pathogens

BMC Genomics, 2012
Background The classical Bordetella subspecies are phylogenetically closely related, yet differ in some of the most interesting and important characteristics of pathogens, such as host range, virulence and persistence.

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.

Increase in pertussis cases along with high prevalence of two emerging genotypes of Bordetella pertussis in Perú, 2012 [PDF]

, 2016
As has occurred in many regions worldwide, in 2012 the incidence of pertussis increased in Perú. This epidemiologic situation has been associated with a waning vaccine-induced immunity and the adaptation of Bordetella pertussis to vaccine-induced ...

Role of (p)ppGpp in Viability and Biofilm Formation of Actinobacillus pleuropneumoniae S8. [PDF]

, 2015
Actinobacillus pleuropneumoniae is a Gram-negative bacterium and the cause of porcine pleuropneumonia. When the bacterium encounters nutritional starvation, the relA-dependent (p)ppGpp-mediated stringent response is activated.
