Department Library & Information Science, Carlos III University, Madrid, Spain.

Over the two last decades, coronaviruses have affected human life in different ways, especially in terms of health and economy. Due to the profound effects of novel coronaviruses, growing tides of research are emerging in various research fields. This paper employs a co-word analysis approach to map the intellectual structure of the coronavirus literature for a better understanding of how coronavirus research and the disease itself have developed during the target timeframe.

Lower airway collapse: Revisiting the definition and clinicopathologic features of canine bronchomalacia.

Vet J 2021 Jul 20;273:105682. Epub 2021 Apr 20.

Department of Sciences Cliniques, Faculté de Médecine Vétérinaire, Université de Montréal, St-Hyacinthe, Canada.

Bronchomalacia (BM) is an inconsistently defined term in dogs, impairing understanding of clinical presentation, therapeutic response and prognosis. Herein the authors propose to clarify the definition of canine bronchomalacia (CBM) as regional to diffuse dynamic airway collapse of segmental and/or subsegmental bronchi with associated clinical signs due to airflow limitation. In contrast to tracheal collapse, mainstem bronchial collapse, and in some cases lobar collapse, CBM requires advanced imaging. Read More

Proteomic analysis of chicken bone marrow-derived dendritic cells in response to an inactivated IBV + NDV poultry vaccine.

Sci Rep 2021 Jun 16;11(1):12666. Epub 2021 Jun 16.

Division of Infectious Diseases and Immunology, Department of Biomolecular Health Sciences, Faculty of Veterinary Medicine, Utrecht University, Utrecht, The Netherlands.

Inactivated poultry vaccines are subject to routine potency testing for batch release, requiring large numbers of animals. The replacement of in vivo tests for cell-based alternatives can be facilitated by the identification of biomarkers for vaccine-induced immune responses. In this study, chicken bone marrow-derived dendritic cells were stimulated with an inactivated vaccine for infectious bronchitis virus and Newcastle disease virus, as well as inactivated infectious bronchitis virus only, and lipopolysaccharides as positive control, or left unstimulated for comparison with the stimulated samples.

Infectious bronchitis virus in Australia: a model of coronavirus evolution - A Review.

Avian Pathol 2021 Jun 15:1-46. Epub 2021 Jun 15.

Asia-Pacific Centre for Animal Health, Melbourne Veterinary School, Faculty of Veterinary and Agricultural Sciences, The University of Melbourne, Parkville 3010, Victoria, Australia.

Infectious bronchitis virus (IBV) was first isolated in Australia in 1962. Ongoing surveillance and characterisation of Australian IBVs have shown that they have evolved separately from strains found throughout the rest of the world, resulting in the evolution of a range of unique strains and changes in the dominant wild type strains, affecting tissue tropism, pathogenicity, antigenicity, and gene arrangement. Between 1961 and 1976 highly nephropathogenic genotype GI-5 and GI-6 strains, causing mortalities of 40% to 100%, predominated, while strains causing mainly respiratory disease, with lower mortality rates have predominated since then.

The contribution of the immune response to enhanced colibacillosis upon preceding viral respiratory infection in broiler chicken in a dual infection model.

Vet Immunol Immunopathol 2021 May 27;238:110276. Epub 2021 May 27.

Division of Infectious Diseases and Immunology, Department Biomolecular Health Sciences, Faculty of Veterinary Medicine, Utrecht University, Yalelaan 1, 3584 CL Utrecht, the Netherlands.

Colibacillosis in chickens caused by avian pathogenic Escherichia coli (APEC) is known to be aggravated by preceding infections with infectious bronchitis virus (IBV), Newcastle disease virus (NDV) and avian metapneumovirus (aMPV). The mechanism behind these virus-induced predispositions for secondary bacterial infections is poorly understood. Here we set out to investigate the immunopathogenesis of enhanced respiratory colibacillosis after preceding infections with these three viruses. Read More

Division of Biomedical Sciences, School of Medicine, University of California, Riverside, Riverside, CA 92521; Pulmonary, Critical Care, Sleep and Allergy Division, University of Nebraska Medical Center, Omaha, NE 68198, USA. Electronic address:

Agricultural workers, especially those who work in swine confinement facilities, are at increased risk for developing pulmonary diseases including asthma, chronic obstructive pulmonary disease, and chronic bronchitis due to exposures to fumes, vapors, and organic dust. Repetitive exposure to agricultural dust leads to unresolved inflammation, a common underlying mechanism that worsens lung disease. Besides occupational exposure to dusts, diet also significantly contributes to inflammation and disease progression. Read More

Review on Pneumococcal Infection in Children.

Cureus 2021 May 9;13(5):e14913. Epub 2021 May 9.

Paediatrics, Base Hospital, Mahaoya, LKA.

Childhood pneumococcal infection is a growing concern among paediatricians especially, in countries where there is no routine vaccination program against . The disease is associated with significant morbidity and mortality in young children particularly those who are under the age of two years. Its main virulent factors include polysaccharide capsule, autolysin, pneumolysin, choline-binding Protein A, the higher chance for genetic transformation, and the presence of pilli that facilitate enhanced binding of bacteria to host cellular surfaces.

Académie nationale de médecine et Académie vétérinaire de France, 16, rue Bonaparte, 75006 Paris, France.

Coronaviruses are RNA viruses classified into Alphacoronavirus, Betacoronavirus, Gammacoronavirus and Deltacoronavirus. Their name comes from their conformation with the observation of spicules forming a sort of crown. Coronaviruses seem to come from bats, and more particularly Alphacoronaviruses and Betacoronaviruses (the genus where zoonoses are observed), while birds are the source of Gammacoronaviruses and Deltacoronaviruses.
