The Uppsala company Pharmacia had great success in the 40s and 50s with, among other things, a plasma replacement product (Macrodex), which is based on dextran produced by L. mesenteroides. Pharmacia was bought by various companies and Macrodex is not produced in Uppsala any longer, but it is used worldwide in both human and veterinary medicine.
|The revised taxonomy of the mollicutes|
The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.Published 2021-11-25. Read more...
