The presence of protein in the urine indicates which of the following

Bess [88]

The presence of protein in the urine is called proteinuria. Proteinuria is an indicator that THE KIDNEYS' FILTRATION MEMBRANE HAS BEEN DAMAGED.
It is the work of the kidneys to filter the blood and remove all the waste products while conserving the materials needed in the body. When body materials such as protein begin to come out with urine in excess of the normal quantity expected, then that means that the kidney is not filtering the blood very well again and this is usually due to damage in the kidney glomeruli which perform the process of filtration.

Assume that one of the disinfectant/antiseptics tested using the disc method had a clear zone of inhibition and to your surprise

o-na [289]

The presence of the minute growth near the disc signifies that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances.

<h3>What are zones of inhibition?</h3>

The sensitivity testing in a microbiology laboratory is done to determine the effect of antibiotics on various bacteria organisms

The zone of inhibition when a disk method is used signifies the area of media where bacteria are unable to grow, due to presence of a drug that impedes their growth.

If there are presence of minute growth near the disc, it means that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances such as disinfectants.

If these mutant bacteria organisms are not cleared by the disk method, it means that they cannot be killed by the disinfectant/antiseptics that is being tested.
