Production and evaluation of antisera for serological type determination of group-B streptococci by double diffusion in agarose gel

Acta Pathologica Et Microbiologica Scandinavica. Section B, Microbiology
N E Jensen


A double diffusion technique for serological typing of Group-B streptococci is presented. The method is valuable both for type determination on a large scale, as well as for evaluation of the specificity of type antisera. As in previously published methods, HC1-extracted antigens are used. The preparation of type antisera is described and the reactions of some selected sera are given in figures. The advantages of the method are good economy of antisera and easy recognition of weak and/or unspecific precipitates. The method is especially useful in epidemiological investigations.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
