Streptococcus uberis strains : South African dairy herd
A retrospective, longitudinal study performed on Streptococcus uberis isolated from milk samples from a large commercial dairy herd in South Africa. Streptococcus uberis isolated from milk samples of dairy cows (Jersey breed), with clinical and sub-clinical mastitis, were identified by MLST (7 gene) sequencing. All of the 70 isolates (63 from 2021 and 7 form 2024), were novel sequence types and were registered on the pubMLST database as part of the Streptococcus uberis isolate collection.

Then scroll down and you will see the data of all 70 isolates, you can click on the id number of each isolate for more information per isolate. If you scroll down, you may download the sequence once you login to the database.
The study involved 70 (63 retrospective and seven recent) samples, isolated from 53 cows, which were used for MLST sequencing of the seven housekeeping genes (gki, recP, ddl, tdk, arc, tpi, and yqiL).
