All the isolates showed positive results for catalase test except CXA3 that which showed catalase negative results (Table-3).
aureus detection using the Baird-Parker agar, Gram staining, and catalase test revealed gymnasium A had the highest number of positive isolates (14/14; 100%), followed by gymnasium B (13/14; 92.86%) and gymnasium C (4/14; 28.57%).
Subclinical mastitis can be recognized indirectly by several diagnostic methods including the California Mastitis Test (CMT), the modified white side test, Somatic Cell Count (SCC), pH, milk electrical conductivity tests, and catalase tests. The SCC and CMT are the most common tests used to diagnose mastitis in dairy goats [15].
The principal biochemical tests performed for this purpose include, lactose fermentation test (LAC), indole test (IND), methyl red test (MR), Voges-Proskauer test (VP), urease test (URE), catalase test (CAT), aerobic and anaerobic test (Ae/An).

BSH lb (Lactobacillus sp.) characterized on the basis of biochemical tests whose antibacterial activity zone was of 2 mm found to be negative for catalase test (no bubble formation), negative for indole test, and negative for nitrate reduction test, citrate test, methyl red Voges-Proskeur test, casein hydrolysis test and for starch agar test (Table 1).
Culture on blood agar showed abundant growth of golden-yellow colonies of staphylococcus(Figure 3).Gram stain, positive catalase test and mannitol fermentation test confirmed it to beStaphylococcus aureus.Other tests like Ziehl-Neelsen stain, KOH mount and fungal cultures were negative.Biopsy was done which wasconsistent with the findings of botryomycosis.
Catalase test was used to differentiate streptococci and from staphylococci.
The presumptive of LAB colonies were tested for Gram staining, catalase test and oxidase test.
The delay in organism identification and completion of aerosolizing procedures (e.g., catalase test) on an open laboratory bench increased the risk for exposure among hospital workers.
Biochemical Tests such as Catalase Test, TSI Test, MRVP Test and Indole Test were also performed for further confirmation of E.coli.
