What is the catalase test? Coagulase test? What does it mean to be: Catalase + Catalase - Coagulase + Coagulase - When working with an unknown that may be Staphylococcus (but you are not sure), how can the two tests help? Give step by step detail of how to determine you are dealing with Staphylococcus and not an organism such as Streptococcus (next week topic).

for differentiation

Explanation:

By gram staining, we can determine about gram-positive and gram-negative bacteria. If bacteria are Gram-positive then for further catalase test perform. If bacteria give catalase-positive then that's mean this bacteria is Staphylococcus. If bacteria give catalase-negative result then that's mean this bacteria is streptococcus.

The bacteria that are catalase-positive for their further identification coagulase test perform if bacteria is coagulase-positive that's mean it is staphylococcus aureus and if it is coagulase-negative that's mean that maybe differentiation saprophyticus or other species.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
