[Use of cross-absorbed sera in neutralization tests with viral titration by the cytopathogenic effect].

Voprosy virusologii, 1975
A new method for intratypic antigenic differentiation of poliovirus strains has been developed. The method is based on the use of cross-absorbed sera in neutralization tests where virus is titrated by the cytopathic effect. Qualitative differences between the antigenic structure of vaccine and "wild" strains as well as between some "wild" strains of ...

Bacterial Toxin Exploits Host Membrane Phospholipid as a Receptor for Binding, Entry, and Cytopathogenicity

Molecular Microbiology, Volume 125, Issue 2, Page 145-158, February 2026.
Mycoplasma pneumoniae pathogenesis relies on its CARDS toxin, which initiates cell binding and subsequent uptake by exploiting sphingomyelin, a key phospholipid found in the host plasma membrane. Maximal cellular entry and full cytotoxic effects are achieved through a synergistic mechanism that involves interaction with the protein coreceptor annexin ...

Highly Virulent Getah Virus Subgroup GIII‐c Emerging in Pigs in China

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Getah virus (GETV) is an emerging mosquito‐borne zoonotic alphavirus that poses a threat to multiple animal species, particularly pigs, and carries significant public health implications. Nevertheless, the molecular evolution and pathogenicity of circulating GETV strains in China remain incompletely defined.
