😷 The risk group for Belgium has been imported on 2024-02-05. The full classification is: risk group = 1, note = "animal pathogen - biological class of risk animal: 2". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 2, note = "PV". — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 2, note = "ht". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
🧍 Jelínková and Köhler suggested that Streptococcus dysgalactiae subsp. dysgalactiae and Streptococcus dysgalactiae subsp. equisimilis should be regarded as separate species on clinical and epidemiological grounds. Current taxonomic evidence did not appear to support this view, although these streptococci are generally regarded as distinct species by clinical microbiologists. — 🧍 The original authorship, (ex Diernhofer 1932) Garvie et al. 1983, was corrected according to the new Rule 40d.Publication:
