Bordetella bronchiseptica

Casandra Hoffman, Joshua Eby, Mary Gray, F Heath Damron, Jeffrey Melvin, Peggy Cotter, Erik Hewlett
Bordetella pertussis, the causative agent of whooping cough, secretes and releases adenylate cyclase toxin (ACT), which is a protein bacterial toxin that targets host cells and disarms immune defenses. ACT binds filamentous hemagglutinin (FHA), a surface-displayed adhesin, and until now, the consequences of this interaction were unknown. A B. bronchiseptica mutant lacking ACT produced more biofilm than the parental strain; leading Irie et al. to propose the ACT-FHA interaction could be responsible for biofilm inhibition...

BACKGROUND: The genus Bordetella consists of nine species that include important respiratory pathogens such as the 'classical' species B. bronchiseptica, B. pertussis and B. parapertussis and six more distantly related and less extensively studied species. Here we analyze sequence diversity and gene content of 128 genome sequences from all nine species with focus on the evolution of virulence-associated factors. RESULTS: Both genome-wide sequence-based and gene content-based phylogenetic trees divide the genus into three species clades...

The baboon model of Bordetella pertussis infection is the newest and most clinically accurate model of the human disease to date. However, among the 15 experimentally infected baboons in this study, a subset of baboons did not exhibit the expected high bacterial colonization levels or increase in white blood cell count. Moreover, cultures of nasopharyngeal wash samples from several baboons suggested B. bronchiseptica coinfection. Analysis of serum antibodies recognizing filamentous hemagglutinin, pertussis toxin and B...

We previously demonstrated that Bordetella bronchiseptica (B. bronchiseptica) antigen (Ag) showed high immunostimulatory effects on mouse bone marrow cells (BMs) while Mycoplasma hyopneumoniae (M. hyopneumoniae) Ag showed low. The focus of this study was if B. bronchiseptica Ag may enhance M. hyopneumoniae Ag-specific immune response, and also the host immune system can recognize both Ags. MTT assay revealed that each or both Ags did not significantly change the cell metabolic activity of BMs. Flow cytometry analysis using carboxyfluorescein succinimidyl ester presented that B...

Bordetella bronchiseptica is a well-known etiological agent of kennel cough in dogs and cats and one of the two causative agents of atrophic rhinitis, a serious swine disease. The aim of the study was to isolate B. bronchiseptica bacteriophages from environmental samples for the first time. A total of 29 phages from 65 water samples were isolated using the strain ATCC 10580 as a host. The lytic spectra of the phages were examined at 25 and 37 °C, using 12 strains of B. bronchiseptica. All phages were able to plaque on 25...

Arylmalonate Decarboxylases (AMDases, EC are very rare and mostly underexplored enzymes. Currently only four known and biochemically characterized representatives exist. However, their ability to decarboxylate α-disubstituted malonic acid derivatives to optically pure products without cofactors makes them attractive and promising candidates for the use as biocatalysts in industrial processes. Until now, AMDases could not be separated from other members of the aspartate/glutamate racemase superfamily based on their gene sequences...

PvuII ribotyping and MLST are each highly discriminatory methods for genotyping Bordetella bronchiseptica, but a direct comparison between these approaches has not been undertaken. The goal of this study was to directly compare the discriminatory power of PvuII ribotyping and MLST, using a single set of geographically and genetically diverse strains, and to determine whether subtyping based on repeat region sequences of the pertactin gene (prn) provides additional resolution. One hundred twenty-two isolates were analyzed, representing 11 mammalian or avian hosts, sourced from the United States, Europe, Israel and Australia...

The small polyamine putrescine (1,4-diaminobutane) is ubiquitously and abundantly found in all three domains of life. It is a precursor, through N-aminopropylation or N-aminobutylation, for biosynthesis of the longer polyamines spermidine, sym-homospermidine, spermine, and thermospermine and longer and branched chain polyamines. Putrescine is also biochemically modified for purposes of metabolic regulation and catabolism, e.g. N-acetylation and N-glutamylation, and for incorporation into specialized metabolites, e...

A molecular survey for traditional and emerging pathogens associated with canine infectious respiratory disease (CIRD) was conducted in Italy between 2011 and 2013 on a total of 138 dogs, including 78 early acute clinically ill CIRD animals, 22 non-clinical but exposed to clinically ill CIRD dogs and 38 CIRD convalescent dogs. The results showed that canine parainfluenza virus (CPIV) was the most commonly detected CIRD pathogen, followed by canine respiratory coronavirus (CRCoV), Bordetella bronchiseptica, Mycoplasma cynos, Mycoplasma canis and canine pneumovirus (CnPnV)...

BACKGROUND: The use of quantitative PCR (qPCR) for detection of Bordetella bronchiseptica in bronchoalveolar lavage fluid (BALF) and demonstration of bacteria adhering to ciliated epithelial cells in BALF or bronchial brushing fluid (BBF) has not been assessed in a series of affected dogs. Coinfections can worsen the clinical severity in bordetellosis, but the specific association with Mycoplasma cynos has not been evaluated. OBJECTIVES: To assess the utility of culture, qPCR and cytologic examination of cytospin preparations in the diagnosis of bordetellosis in dogs and the influence of coinfection by M...

Bordetella bronchiseptica is a bacterial pathogen usually isolated from animals and rarely causes human infections. There are, however, some reports that B. bronchiseptica causes human respiratory infections in immunocompromised patients or those with underlying respiratory diseases, although there is a lack of treatment guidelines. An 80-year-old woman was admitted to our hospital to treat anti-neutrophil cytoplasmic antibodies-associated vasculitis. On the 16th day after admission, she complained of a productive cough with right pleuritic pain and had low-grade fever...

Biofilm formation is important for infection by many pathogens. Bordetella bronchiseptica causes respiratory tract infections in mammals and forms biofilm structures in nasal epithelium of infected mice. We previously demonstrated that cyclic di-GMP is involved in biofilm formation in B. bronchiseptica. In the present work, based on their previously reported function in Pseudomonas fluorescens, we identified three genes in the B. bronchiseptica genome likely involved in c-di-GMP-dependent biofilm formation: brtA, lapD and lapG...

ComPath is a pan-European resistance monitoring programme collecting bacterial pathogens from dogs and cats. We present data for respiratory tract infection (RTI) isolates collected between 2008 and 2010. Antimicrobial minimal inhibitory concentrations (MICs) were determined and susceptibility calculated following Clinical Laboratory Standards Institute (CLSI) standards for veterinary medicine. The main pathogen from dogs was Staphylococcus intermedius Group (49/215, 22.8%) which was >90% susceptible to most antimicrobials (including oxacillin - 93...

Porcine reproductive and respiratory syndrome virus (PRRSV) is an economically important disease around the globe. Protection against this virus remains problematic. Here, we evaluated antibody (IgG & IgA) inducibility of a heterologous PRRSV glycoprotein 5 (GP5) expressed in a live attenuated Bordetella bronchiseptica aroA mutant strain (BBS-GP5). Mice and pigs were primed with recombinant GP5 (rGP5) subcutaneously followed by boosting with live BBS-GP5. As a result, anti-GP5 IgG was induced in both mice (P<0...

BACKGROUND: Actinobacillus pleuropneumoniae is the etiologic agent of porcine contagious pleuropneumonia, which causes important worldwide economic losses in the swine industry. Several respiratory tract infections are associated with biofilm formation, and A. pleuropneumoniae has the ability to form biofilms in vitro. Biofilms are structured communities of bacterial cells enclosed in a self-produced polymer matrix that are attached to an abiotic or biotic surface. Virtually all bacteria can grow as a biofilm, and multi-species biofilms are the most common form of microbial growth in nature...

In order to determine the comparative efficacy of vaccines administered intranasally or orally to protect puppies from disease subsequent to experimental infection with Bordetella bronchiseptica (Bb), a randomized controlled trial was performed using 48 approximately 8-week-old specific pathogen free, Bb naive Beagle puppies. Puppies were randomized into three groups and administered vaccines containing Bb intranasally or orally, or a placebo intranasally. Twenty-one days later, all dogs were challenge exposed via aerosol administration of Bb...

BACKGROUND: Excessive production of free radicals has been implicated in many diseases including cancer. They are highly reactive and bring about oxidation of biomolecules i.e., proteins, lipids and nucleic acids which are associated with many degenerative diseases. Natural products acting as antioxidants have ability to neutralize free radicals and their actions and hence they mitigate their harmful effects. The present study was designed to investigate pharmacological properties viz...
