Evaluation of the genetic variability found in Brazilian commercial vaccines for infectious bronchitis virus [PDF]

, 2017
Infectious bronchitis virus (IBV) is currently one of the most important pathogens in the poultry industry. The H120 and Ma5 are the only viral strains approved by the Brazilian government as the constituent of vaccines.

Protective Efficacy of Different Live Attenuated Infectious Bronchitis Virus Vaccination Regimes Against Challenge With IBV Variant-2 Circulating in the Middle East

Frontiers in Veterinary Science, 2019
Six vaccination regimes using classical (Mass-type) and variant (IB-VAR2 and IB-793B) live vaccines were evaluated against Middle Eastern variant-2 infectious bronchitis virus challenge.

Heterogeneity of infectious bronchitis virus grown in eggs [PDF]

Archives of Virology, 1976
Egg-grown infectious bronchitis virus, strain Beaudette, was concentrated and centrifuged on sucrose density gradients to separate the virus into five peaks with densities of 1.144, 1.160, 1.172, 1.191 and 1.218 g/cm3. All peaks retained infectivity, complement fixation activity and were labelled with 3H-uridine.

Large‐scale meta‐analysis of infection risk with JAK–STAT inhibitors in 29,000 patients

Journal of the European Academy of Dermatology and Venereology, EarlyView.
In this large meta‐analysis of 74 randomized controlled trials involving more than 29,000 patients, JAK–STAT inhibitors were associated with an increased risk of influenza, bronchitis and herpes infections, particularly herpes zoster, while an increased risk of serious opportunistic or fungal infections was not observed.

Haemagglutination by Avian Infectious Bronchitis Virus -- a Coronavirus

Journal of General Virology, 1975
The haemagglutinating ability of three strains of IBV was investigated. It was shown that whereas strain Beaudette had no detectable haemagglutinin, both Connecticut and Massachusetts agglutinated red cells of various species. The haemagglutinin of Connecticut was detectable after sucrose gradient purification whereas that of Massachusetts required ...

Peri‐Implantitis and Periodontitis: Biological Convergence, Contextual Divergence

Journal of Periodontal Research, EarlyView.
Periodontal and peri‐implant tissues differ and coincide in many aspects, from the clinical and radiological perspective, including histology, microbiology, and molecular markers. Thus, health and disease may also follow different and similar routes.

Evolution of infectious bronchitis virus in the field after homologous vaccination introduction

Veterinary Research, 2019
Despite the fact that vaccine resistance has been typically considered a rare phenomenon, some episodes of vaccine failure have been reported with increasing frequency in intensively-raised livestock.

Antigenicity of the peplomer protein of infectious bronchitis virus

Molecular Immunology, 1989
To study the antigenic structure of the peplomer protein of the avian coronavirus infectious bronchitis virus, fragments from the peplomer gene were generated by restriction-enzyme cleavage or by limited DNase digestion and inserted in the Escherichia coli expression plasmid pEX (Stanley and Luzio, 1984). The antigenicity of the expression products was

Joint Effects of Prenatal Antibiotics, Mode of Birth and Breastfeeding Duration on Childhood Infections: The Norwegian MoBa Cohort Study

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Prenatal antibiotic exposure and caesarean births are associated with an increased risk of hospitalised infection in children, but few studies have evaluated their impact on less severe infections and possible joint effects. Conversely, longer breastfeeding duration is protective against infections, but whether this effect varies ...
