Indirect hemagglutination test for detection of antibodies to cytomegalovirus is highly sensitive and reproducible, if employed in well-defined conditions. Standardization of the various factors involved is necessary as well as their reciprocal equilibrium : sheep erythrocytes, antigen, dilution of tanin, buffers quality. The hemagglutination test can be performed on small volumes such as blood collection on blotting paper (PKU). Antibody titers were compared in the serum and the blood so collected in 104 subjects : the results were very similar and no "false negative" were found in any case. This way of collecting blood and hemagglutination are technical improvements in epidemiologic studies of cytomegalovirus infection. It can be hoped they will be adapted to other group herpes infections.

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.

Introduction: Varicella-Zoster virus (VZV) is a highly contagious alpha-herpes virus. The diagnosis of chickenpox remains a difficult task especially in cases of breakthrough chickenpox, so the development of reliable laboratory tests is necessary. The simplest and most sensitive serological test for detecting antibodies in human and animal sera is the passive hemagglutination reaction (PHAR).

The peculiar characteristics and advancement in diagnostic methodologies of influenza A virus.

Front Microbiol

January 2025

CAS Key Laboratory of Molecular Virology and Immunology, Institutional Center for Shared Technologies and Facilities, Pathogen Discovery and Big Data Platform, Shanghai Institute of Immunity and Infection, Chinese Academy of Sciences, Shanghai, China.

Influenza A virus (IAV) is a significant public health concern, causing seasonal outbreaks and occasional pandemics. These outbreaks result from changes in the virus's surface proteins which include hemagglutinin and neuraminidase. Influenza A virus has a vast reservoir, including wild birds, pigs, horses, domestic and marine animals.
