Streptococcus uberis

Fig. 19:5. Streptococcus uberis cultivated on a SELMA plate at 37°C during 24 h. Note that S. uberis is only growing in sector 1 (blood agar with esculine). Image A was photographed with lighting from above and image B with lighting from below. The hemolysis is most clearly visible in image B. The cultivation media in the other sectors are given in the media list under SELMA plate. S. uberis has only a weak esculinase activity and it is, therefore, difficult to see that it is actually esculinase positive. Date: 2017-06-07.
