Abstract
Background
Bordetella bronchiseptica is a primary pathogen in canine infectious respiratory disease (CIRD), or kennel cough, capable of independently causing respiratory illness and contributing significantly to co-infections with other viral and bacterial agents. Despite its critical role in disease transmission and persistence, the epidemiology of B. bronchiseptica in CIRD remains poorly understood. Limited data on co-infection prevalence and associated risk factors hinder effective management and control of this pathogen.
Objective
This systematic review and meta-analysis aimed to clarify the prevalence and risk factors of co-infections with B. bronchiseptica in dogs.
Methods
A comprehensive bibliographic search was conducted across four databases: PubMed, Scopus, Web of Science, and Embase. Data extraction included the number of co-infected cases among those with B. bronchiseptica, the identified co-infecting pathogens, study period, geographical location, shelter type, and age.
Results
From 3994 identified articles, 26 studies were included. The overall prevalence of B. bronchiseptica co-infection was 47 % (95 % CI: 37 %-57 %). Significant differences were observed only in the study period, with co-infection rates higher in the 1900s (77 %) compared to the 2000s (45 %). No significant differences were found for other factors. Frequently co-infecting pathogens included Mycoplasma and canine respiratory coronavirus (CRCoV).
Conclusion
Co-infections with B. bronchiseptica are common in CIRD, indicating a need for the development of combined vaccines targeting co-infecting pathogens. Furthermore, the establishment of effective prevention and control strategies can be universally applied across different geographical locations, shelter types, and ages. This study provides valuable insights that can inform future research and enhance the overall management and treatment of CIRD in dogs.
期刊介绍：
The journal reports basic, comparative and clinical immunology as they pertain to the animal species designated here: livestock, poultry, and fish species that are major food animals and companion animals such as cats, dogs, horses and camels, and wildlife species that act as reservoirs for food, companion or human infectious diseases, or as models for human disease.
Rodent models of infectious diseases that are of importance in the animal species indicated above,when the disease requires a level of containment that is not readily available for larger animal experimentation (ABSL3), will be considered. Papers on rabbits, lizards, guinea pigs, badgers, armadillos, elephants, antelope, and buffalo will be reviewed if the research advances our fundamental understanding of immunology, or if they act as a reservoir of infectious disease for the primary animal species designated above, or for humans. Manuscripts employing other species will be reviewed if justified as fitting into the categories above.
The following topics are appropriate: biology of cells and mechanisms of the immune system, immunochemistry, immunodeficiencies, immunodiagnosis, immunogenetics, immunopathology, immunology of infectious disease and tumors, immunoprophylaxis including vaccine development and delivery, immunological aspects of pregnancy including passive immunity, autoimmuity, neuroimmunology, and transplanatation immunology. Manuscripts that describe new genes and development of tools such as monoclonal antibodies are also of interest when part of a larger biological study. Studies employing extracts or constituents (plant extracts, feed additives or microbiome) must be sufficiently defined to be reproduced in other laboratories and also provide evidence for possible mechanisms and not simply show an effect on the immune system.
