In this study, 110 sera samples taken from healthy persons were tested for BK virus antibodies by using hemagglutination inhibition (HI), ELISA and complement fixation (CF) tests to detect the sensitivity, specificity and agreement of these tests. The results of each individual test was compared with others for sensitivity and specificity. Specificity found to be 96% when HI and CF tests were compared. Sensitivity also found to be 92.7% when CF and ELISA tests were compared. Agreement of HI and ELISA tests were 88%.

Japanese encephalitis (JE) is a zoonotic disease caused by the Japanese encephalitis virus (JEV), belonging to the family. Diagnosis of Japanese encephalitis (JE) based on clinical signs alone is challenging due to the high proportion of subclinical cases. The Plaque Reduction Neutralization Test (PRNT) is considered the gold standard for detecting JE-specific antibodies because of its high specificity.

Background: Polypeptide vaccines have the potential to improve immune responses by targeting conserved and weakly immunogenic regions in antigens. This study aimed to identify and evaluate the efficacy of a novel influenza universal vaccine candidate consisting of multiple polypeptides derived from highly conserved regions of influenza virus proteins hemagglutinin (HA), neuraminidase (NA), and matrix protein 2 (M2).
Methods: Immunoinformatics tools were used to screen conserved epitopes from different influenza virus subtypes (H1N1, H3N2, H5N1, H7N9, H9N2, and IBV).
HA198 mutations in H9N2 avian influenza: molecular dynamics insights into receptor binding.

Introduction: The H9N2 avian influenza virus is widely disseminated in poultry and poses a zoonotic threat, despite vaccination efforts. Mutations at residue 198 of hemagglutinin (HA) are critical for antigenic variation and receptor-binding specificity, but the underlying molecular mechanisms remain unclear. This study explores the molecular mechanisms by which mutations at the HA 198 site affect the antigenicity, receptor specificity, and binding affinity of the H9N2 virus.

Introduction: Animal influenza viruses pose a danger to the general public. Eurasian avian-like H1N1 (EA H1N1) viruses have recently infected humans in several different countries and are often found in pigs in China, indicating that they have the potential to cause a pandemic. Therefore, there is an urgent need to develop a potent vaccine against EA H1N1.

Newcastle disease (ND) is a notifiable avian disease responsible for several panzootics, which has resulted in the establishment of mandatory vaccination programs against the virus in several countries including Denmark. This study compared the immune response elicited in layers by the standard vaccination program for ND of a Danish commercial egg production facility with a simplified version of the vaccination program. A commercial flock of layers was followed for 77 weeks from hatching to culling.
