Bordetella Type III Secretion Injectosome and Effector Proteins

Frontiers in Cellular and Infection Microbiology, 2020
Pertussis, also known as whooping cough, is a resurging acute respiratory disease of humans primarily caused by the Gram-negative coccobacilli Bordetella pertussis, and less commonly by the human-adapted lineage of B. parapertussisHU.

Bordetella spp. utilize the type 3 secretion system to manipulate the VIP/VPAC2 signaling and promote colonization and persistence of the three classical Bordetella in the lower respiratory tract

Frontiers in Cellular and Infection Microbiology, 2023
IntroductionBordetella are respiratory pathogens comprised of three classical Bordetella species: B. pertussis, B. parapertussis, and B. bronchiseptica. With recent surges in Bordetella spp.

Improvement of Mycoplasma pneumoniae–Associated Acute Cerebellar Ataxia and Possible Encephalopathy After Intravenous Immunoglobulin

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Mycoplasma pneumoniae (M. pneumoniae) can cause acute postinfectious cerebellar ataxia and encephalitis/encephalopathy. Although ataxia can be self‐limited, prolonged duration of symptoms and long‐term neurological sequelae that persist for months or more are associated with both conditions.

B. parapertussis does not induce ROS in resting neutrophils.

, 2017
B. parapertussis (Bpp) or B. parapertussis Δwbm (BppΔwbm) were incubated with neutrophils (MOI: 100) and luminol at 37°C. Neutrophils incubated with medium alone and luminol served as a negative control.

Suspected Macrolide‐Refractory Mycoplasma pneumoniae Pneumonia With Discordant Coccidioides Serology in an Immunocompromised Host: A Case Report

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Suspected macrolide‐refractory Mycoplasma pneumoniae pneumonia can be a diagnostic challenge in immunocompromised hosts, particularly after allogeneic stem cell transplantation. Screening serologies may further complicate diagnosis when false‐positive or discordant results divert therapy.

Severe Necrotizing Community‐Acquired Pneumonia and Bilateral Empyema in an Immunocompetent Patient due to Fusobacterium necrophorum

Case Reports in Pulmonology, Volume 2026, Issue 1, 2026.
Necrotizing pneumonia and empyema caused by Fusobacterium necrophorum are uncommon. The classical presentation of Lemierre′s syndrome, characterized by pharyngotonsillitis and internal jugular vein thrombosis, is not always observed, and incomplete and atypical variants can cause diagnostic uncertainty and delay in treatment.

Bordetella parapertussis Circumvents Neutrophil Extracellular Bactericidal Mechanisms [PDF]

, 2019
B. parapertussis is a whooping cough etiological agent with the ability to evade the immune response induced by pertussis vaccines. We previously demonstrated that in the absence of opsonic antibodies B.

Identification of a CO2 responsive regulon in Bordetella. [PDF]

PLoS ONE, 2012
Sensing the environment allows pathogenic bacteria to coordinately regulate gene expression to maximize survival within or outside of a host. Here we show that Bordetella species regulate virulence factor expression in response to carbon dioxide levels ...
