Evaluation of the protective immunity of Riemerella anatipestifer OmpA

Applied Microbiology and Biotechnology, 2019
Riemerella anatipestifer is responsible for an economically important disease of commercially raised ducks. No or only few cross-protection was observed between different serotypes of R. anatipestifer strains, and so far no protective antigen in this bacterium has been identified. OmpA is a predominant immunogenic protein of R.

Upregulation of duck interleukin-17A during Riemerella anatipestifer infection

Developmental & Comparative Immunology, 2016
Although IL-17 cytokines play critical roles in host defense immunity, dysregulated expression of these cytokines is associated with inflammation and autoimmune diseases. Riemerella anatipestifer is the most important infectious bacterium in the duck industry. Interestingly, not all avian species are equally susceptible to R.

Bioinformatic characterization of epsA Gene from Riemerella anatipestifer

2012 5th International Conference on BioMedical Engineering and Informatics, 2012
The epsA gene (Gene ID:11997253) of Riemerella anatipestifer (RA) was isolated in our laboratory. By using bioinformatics tools, the biological characteristics of epsA gene and EpsA protein was analyzed. The epsA gene was a 900-bp complete open reading frame, encoding EpsA protein of 299 amino acids. The relative molecular weight of EpsA protein was 32.

Assessment of immunization regimens of duck Riemerella anatipestifer vaccines

Journal of Applied Microbiology, 2020
Riemerella anatipestifer infections of goslings and ducklings can result in high mortality. Since there are at least 21 serotypes of R. anatipestifer, cross-protection is an important goal for vaccine development.In this study, we evaluated the immunostimulatory effect of different immunization regimens - the traditional inactivated vaccine vs prime ...

Immunoproteomics analysis of whole cell bacterial proteins of Riemerella anatipestifer

Veterinary Microbiology, 2012
Riemerella antipestifer is one of the most important duck pathogens. It has worldwide distribution, and the lack of the information on bacteria-host interactions and an effective vaccine are limitations on the control of this infection. In this study, an immunoproteomic assay was used to identify immunogenic proteins among the whole cell bacterial ...

Molecular characterization of a plasmid isolated fromRiemerella anatipestifer

Avian Pathology, 1998
Sixty strains of Riemerella anatipestifer were isolated from ducks and geese with infectious serositis in Taiwan. Sixty per cent of the isolates (36/60) contained a 3.9 b plasmid, 12% (7/60) contained 6.5 b and 16 b plasmids, 5% (3/60) contained 2.9, 16 and 18 b plasmids and 13% contained no plasmid (14/60).

Construction of a shuttle vector for use in Riemerella anatipestifer

Journal of Microbiological Methods, 2013
Riemerella anatipestifer causes epizootic infectious disease in poultry and serious economic losses, especially to the duck industry. Four complete genome sequences of R. anatipestifer strains are now available. However, functional studies have been limited by the lack of an effective shuttle vector. In this study, we constructed a shuttle vector, pRES,

Isolation and characterization of atypical Riemerella columbina strains from pigeons and their differentiation from Riemerella anatipestifer

Veterinary Microbiology, 2011
Riemerella columbina (RC) and Riemerella anatipestifer (RA) belong to the genus Riemerella within the family Flavobacteriaceae. While RA is a well-described pathogen of waterfowl and other avian species, only little is known about RC. Previous work reporting the isolation of RC from internal organs of clinically diseased pigeons suggested a potential ...

The Detection of Hemin-Binding Proteins in Riemerella anatipestifer CH-1

Current Microbiology, 2015
Riemerella anatipestifer (R. anatipestifer) is among the most prevalent duck pathogens, causing acute or chronic septicemia characterized by serositis. Riemerella anatipestifer can be grown on blood-enriched media, in vitro, which provides a hemin source essential for the sustainment of R. anatipestifer and activation of hemin-uptake systems.

Complete Genomic Sequence of the Virulent Bacteriophage RAP44 of Riemerella anatipestifer

Avian Diseases, 2012
A virulent Riemerella anatipestifer bacteriophage, RAP44, belonging to the Siphoviridae family of tailed phages, was previously isolated from feces of healthy Muscovy ducks in China. A complete genomic sequence analysis indicates that the phage's genome consists of a linear, double-stranded DNA molecule of 49,329 nucleotides. Eighty open reading frames
