The serological cross-reactions among stable L-forms of Pseudomonas aeruginosa, or of Streptococcus pyogenes and mycoplasmas were investigated in passive hemagglutination (PHA) and agar gel diffusion tests. (1) PHA active fraction which reacts most strongly with homologous serum was obtained from the sodium dodecyl sulfate soluble fraction of L-form membrane after disruption by Braun cell homogenizer. (2) Antiserum prepared against L-forms in rabbits showed high-level stimulation of PHA antibodies, while it showed little stimulation of agglutinating antibodies. (3) In PHA and agar gel diffusion tests, antiserum to L-form of P. aeruginosa strain IFO-3,455 reacted with L-form of strain N-10, which is serologically different in serotype from strain IFO-3,455. Furthermore, the two L-forms of P. aeruginosa cross-reacted with a L-form of S. pyogenes. 4) L-forms of P. aeruginosa and S. pyogenes did not react with five strains of mycoplasmas in PHA and agar gel diffusion tests.

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.
