Harnessing the potential of blood donation archives for influenza surveillance and control.

PLoS ONE, 2020
Many blood donation services around the globe maintain large archives of serum and/or plasma specimens of blood donations which could potentially be used for serologic surveillance and risk assessment of influenza.

استانداردسازی الایزا برای ردیابی پادتن ویروس برونشیت عفونی [PDF]

Archives of Razi Institute, 2005
An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain).

The use of equine influenza pseudotypes for serological screening [PDF]

, 2012
Standard assays used for influenza serology present certain practical issues, such as inter-laboratory variability, complex protocols and the necessity for handling certain virus strains in high biological containment facilities.

Structural and functional characterization of the newly identified Photorhabdus laumondii tumor necrosis factor‐like lectin

The FEBS Journal, EarlyView.
We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

Substitutions near the hemagglutinin receptor-binding site determine the antigenic evolution of influenza A H3N2 viruses in U.S. swine [PDF]

, 2014
Swine influenza A virus is an endemic and economically important pathogen in pigs, with the potential to infect other host species. The hemagglutinin (HA) protein is the primary target of protective immune responses and the major component in swine ...

Characterising the Transcriptomic Response to Interferon and Infection in European Domestic Ferret Respiratory Tissues Using Long‐Read RNA Sequencing

Immunology, EarlyView.
We utilised long‐read Nanopore sequencing to characterise the transcriptome of ferret cell lines stimulated with IFN‐α as well as nasal turbinates from ferrets infected with influenza A virus. We identified novel genes and isoforms and observed elongation of poly(A) tails in the ribosome and Coronavirus Disease‐19 pathways in response to IFN‐α ...

Antibiotic‐mediated immune modulation in periodontitis

Periodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...

Oseltamivir-Resistant Influenza Viruses A (H1N1) during 2007–2009 Influenza Seasons, Japan

Emerging Infectious Diseases, 2010
To monitor oseltamivir-resistant influenza viruses A (H1N1) (ORVs) with H275Y in neuraminidase (NA) in Japan during 2 influenza seasons, we analyzed 3,216 clinical samples by NA sequencing and/or NA inhibition assay. The total frequency of ORVs was 2.6% (

Localization of an endogenous lectin in chicken liver, intestine, and pancreas. [PDF]

, 1979
Extracts of adult chicken liver, pancreas, and intestine contain high levels of a lectin which appears to be identical to one previously purified from embryonic chick muscle.

Influenza hemagglutination-inhibition antibody titer as a mediator of vaccine-induced protection for influenza B.

Clinical Infectious Diseases, 2018
Background The hemagglutination inhibition (HAI) assay is an established correlate of protection for the inactivated influenza vaccine, but the proportion of vaccine-induced protection that is mediated by the post-vaccination HAI titer has not been ...
