What is the difference between a mixed culture and a contaminated culture?
A mixed culture is a container that holds two or more identified and easily differentiated species of microorganisms. A contaminated culture was once pure or mixed (and thus a known entity) but since had contaminants (unwanted microbes of uncertain identity) introduced into it.
How would a contaminated unknown sample affect the accurate identification of the unknown?
A contaminated unknown sample could potentially introduce foreign material that may interfere with the identification process. This contamination could lead to misleading results or hinder the ability to correctly identify the unknown sample. It is important to ensure the sample is pure and free from contamination for accurate identification.
A small sample taken from the body and placed on a medium to allow bacteria growth is a?
A small sample taken from the body and placed on a medium to allow bacteria growth is called a culture. This process helps identify and analyze the type of bacteria present in the sample, which is crucial for effective diagnosis and treatment of infections.
Why will the observed melting point range be lower than true value if we heat the sample too fast?
A lower and wider melting point range could indicate that the sample was contaminated with trace amounts of impurities.
What if the potassium cholrate sample is contaminated with moisture?
If a potassium chlorate sample is contaminated with moisture, it can lead to inaccurate measurements and affect its reactivity. The presence of water may cause the potassium chlorate to partially dissolve, altering its concentration and leading to inconsistent results in reactions or experiments. Additionally, moisture can promote decomposition or reduce the stability of the compound, which can pose safety risks during handling or storage. Proper storage in a dry environment is essential to maintain the integrity of the sample.
What is the difference between a mixed culture and a contaminated culture?
A mixed culture is a container that holds two or more identified and easily differentiated species of microorganisms. A contaminated culture was once pure or mixed (and thus a known entity) but since had contaminants (unwanted microbes of uncertain identity) introduced into it.
What does blood test contaminated mean?
It depends on the situation, it can mean that the sample was contaminated by improper cleansing technique, it can be contaminated by I.V. fluid, or it can be contaminated by tissue fluid. Most all scenarios of contamination are directly related to the skill and integrity of the one collecting the blood sample.
How do you know if a sample is more contaminated than other?
You can determine if a sample is more contaminated than another by comparing the levels of contaminants present in each sample. This can be done through analytical testing methods such as chemical analysis or microbiological testing. The sample with higher concentrations of contaminants is considered more contaminated than the sample with lower concentrations.
What are the number of sulfur atoms in a sample of 21.6 g of mercury1 nitrate?
Mercury I nitrate does not contain sulfur unless the sample is contaminated.
How would a contaminated unknown sample affect the accurate identification of the unknown?
A contaminated unknown sample could potentially introduce foreign material that may interfere with the identification process. This contamination could lead to misleading results or hinder the ability to correctly identify the unknown sample. It is important to ensure the sample is pure and free from contamination for accurate identification.
Is an epithelial cell count of 90 per uL cause for concern?
It means the sample is contaminated.
Does menstruating contaminate urine sample?
It is very common for a person who is menstruating to contaminate a urine sample. Of course, contaminated urine samples are very common in general.
How do you collect the sample for blood culture?
go to a docter
What if a potassium chlorate sample is contaminated with moisture. Would an analysis show the experimental oxygen higher or lower than the theoretical oxygen?
The experimental oxygen would be higher than the theoretical oxygen in a contaminated sample of potassium chlorate. This is because the moisture would contribute to the sample's weight when measured, resulting in a higher oxygen content calculation compared to the theoretical amount based on the chemical formula.
What happens if acetic acid boils at 90 degrees instead of 118?
It is most likely not acetic acid, or the sample maybe contaminated
How do you preserve a sample for culture and sensitivity?
To preserve a sample for culture and sensitivity testing, it should be collected aseptically in a sterile container. The sample should be kept at the appropriate temperature and delivered to the lab promptly to prevent overgrowth of contaminating organisms. It is important to follow specific guidelines provided by the laboratory for proper preservation and transportation of the sample.
