Standardized procedure for determination of staphylocoagulase.

Determination of standardized prececal protein digestibility of canola meal in British United Turkeys Big 6 at different ages using multiple linear regression procedure

ABSTRACT- Ninety six 2-week-old British United Turkeys (BUT) Big 6 were assigned to 2 groups (4 replicates of 12 birds each). One basal diet and another one in which 20% canola meal replaced the corn starch in the basal diet were prepared. At 9, 16 and 21 wk of age, four birds from each pen slaughtered for digesta collection. The last two-third segment of the intestine, between the Meckel’s div...

Rapid and direct staphylocoagulase assay that uses a chromogenic substrate for identification of Staphylococcus aureus.

A rapid and direct assay of staphylocoagulase that uses chromogenic substrate Chromozym TH was developed for the routine identification of Staphylococcus aureus. False-positive and false-negative reactions were eliminated by measuring the activity of staphylocoagulase-prothrombin complex directly. The method was compared with three clotting assays. The results show that the new assay is specifi...
