A urine culture with mixed flora consisting predominately of nonpathogens is usually an incomplete test. This generally means that urine was not obtained by a clean catch method.
Preliminary results are usually available in 24-48 hours, but the final results are allowed to grow for 72 hours, and only after that time is a culture result considered final.
Ensuring that your culture is pure is very important to getting accurate results of your gram stain. One way to tell if your culture is pure is to test both the control and the experiment cultures. If you get a different result than the one you were expecting, you might have a corrupted culture. Making sure that you have several items of each is helpful, as well.
For the DNase test, 24 hours is sufficient to be able to examine the culture. The test result should be recorded after this amount of time has passed, and then it must be discarded.
Cultures look for bacterial growth. And thus in order for bacteria to grow in a given culture medium LIVE bacteria are needed. Depending on the mechanism for obtaining a sample, and the sample placed in the culture medium (i.e. swab, probe, biopsy, blood, etc.) the probability of obtaining live bacteria varies. Pus that usually accompanies an infection is composed of dead bacteria within white blood cells. And thus the swab of a skin wound full of pus is UNlikely to yield a positive (defined by bacterial growth in the culture medium) result. In short live bacteria is needed for a culture to be reported as positive. Not all samples taken for culture contain live bacteria, even in the presence of an infection (it is just the live bacteria are too deep to be accessed by the sampling technique used. I hope this answers your question. Sincerely, Matthew C. Lee, MD, RPh, MS
The glia is the "glue of the brain" as stated above (consisting of astrocytes, microglia and oligodendrocytes), however gliosis is the brains form of a scar. Astrocytes have primarily structural and nutritional roles. They are more resilient and are a prominent component in the reaction to injury. Through proliferation and hypertrophy they create the brain's analogy of a scar (gliosis). Gliosis may result from a variety of insults to the CNS.
Yes, I think so. I am not a professor but it seems obvious to me. Culture is also representative of the community so it is an end result of a community as well as a constant stimulus. Can have one without the other. Culture is by definition a result of a community. No culture, no community. No community, no culture.

The kind of culture that Turkey has at the moment is a mixed culture. This is as a result of interaction with other cultures especially in urban centers.
The region of Russia that is called the Derbent is the region that is predominantly Muslim. This was as a result of the Arab conquests in the eight century.

Human behavior is influenced by both culture and heredity. While genetics play a role in shaping certain traits and tendencies, culture, upbringing, and environment also have a significant impact on shaping behavior. It is a complex interplay between nature and nurture that contributes to human behavior.
