Aerosol infection of mice with Bordetella pertussis [PDF]

Infection and Immunity, 1980
Aerosol inhalation of Bordetella pertussis Tohama phase I resulted in a reproducible and uniform infection of mice (strain DDY or ICR). Mice in groups of 10 exposed for 30 min to aerosols generated from bacterial suspensions of 10(9) and 10(10) organisms per ml resulted in mean bacterial counts of 2.3 (+/- 0.3) X 10(4) and 1.0 (+/- 0.3) X 10(5) colony ...

Otitis in pet guinea pigs: Causes, clinical signs, treatment and outcomes

Veterinary Record, EarlyView.
Abstract Background Otitis is a major disease impacting both pet guinea pigs and laboratory guinea pigs that are used as models in human otological studies. Methods Medical records from two veterinary clinics were retrospectively reviewed to identify guinea pigs diagnosed with computed tomography (CT)‐confirmed otitis between 2014 and 2023.

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.

Swedish Infants Developed Pertussis at a Younger Age if Their Mother Was the Possible Source of Infection in 2009–2015

Acta Paediatrica, EarlyView.
ABSTRACT Aim The aim of this study was to investigate the possible source of laboratory‐confirmed pertussis in infants under 6 months of age. Methods This nationwide prospective study was based on laboratory‐confirmed cases reported in the enhanced pertussis surveillance in Sweden from 2009 to 2015. The parents or carers of 345 infants were interviewed

Infection-acquired versus vaccine-acquired immunity in an SIRWS model [PDF]

, 2017
Despite high vaccine coverage, pertussis has re-emerged as a public health concern in many countries. One hypothesis posed for re-emergence is the waning of immunity.

Bacterial outer membrane vesicles and vaccine applications [PDF]

, 2014
Vaccines based on outer membrane vesicles (OMV) were developed more than 20 years ago against Neisseria meningitidis serogroup B. These nano-sized structures exhibit remarkable potential for immunomodulation of immune responses and delivery of “self ...

Opportunistic Pulmonary Bordetella hinzii Infection after Avian Exposure

Emerging Infectious Diseases, 2015
We report 2 cases of pulmonary Bordetella hinzii infection in immunodeficient patients. One of these rare cases demonstrated the potential transmission of the bacteria from an avian reservoir through occupational exposure and its persistence in humans ...
