Why are aerobic cultures drawn before anaerobic cultures?
Aerobic cultures are typically drawn first because aerobic bacteria are more likely to be present in the sample and grow faster than anaerobic bacteria. This allows for quicker identification and treatment of potential infections.
What is axenic culture?
Axenic culture refers to the growth of pure microbial cultures devoid of any other contaminating organisms. This is achieved by using sterile techniques and media to ensure that only the desired microorganism can grow. Axenic cultures are important for studying the characteristics and behavior of specific microorganisms without interference from other organisms.
How can some anaerobes be maintained in pure cultures?
Some anaerobes can be maintained in pure cultures using specialized techniques such as anaerobic chambers or jars that provide an oxygen-free environment. These techniques allow for the growth and maintenance of anaerobic bacteria without exposure to oxygen which can be harmful or inhibit their growth. Additionally, using specific growth media and incubation conditions that support anaerobes can help in maintaining pure cultures of these organisms.
What is the distinct pseudomonas smell associated with bacterial infections and how can it be identified and treated effectively?
The distinct pseudomonas smell associated with bacterial infections is often described as a sweet, grape-like odor. It can be identified through laboratory tests such as cultures and sensitivity testing. Treatment typically involves antibiotics that are effective against pseudomonas bacteria, such as ciprofloxacin or meropenem. In severe cases, intravenous antibiotics may be necessary. It is important to consult a healthcare professional for proper diagnosis and treatment.
What is the function of a petri dish in laboratory experiments?
A petri dish is used in laboratory experiments to hold and grow cultures of microorganisms or cells. It provides a controlled environment for studying the growth and behavior of these organisms under specific conditions.
What name is given to cultures for identification of organisms as well as the identification of sensitivities of the organism's to antibiotics?
culture and sensitivity
How do antibiotics effect sputum cultures?
Antibiotics in the person's system may prevent microorganisms present in the sputum from growing in culture.
Which cultures can be used for the identification of staphylococcus aureus from blood?
beta hemolysis
Why it is necessary to make pure subcultures of organisms grown from clinical specimen?
Making pure subcultures is necessary to accurately identify the specific organism causing an infection. This helps in determining the appropriate treatment, as different organisms may respond differently to various antibiotics. Pure cultures also help in studying the properties of the organism, such as its growth characteristics and virulence factors.
What is the purpose of growing organisms in blood cultures taken from patients?
These organisms can then be grown and identified in the laboratory so that the proper antibiotic can be given to the patient.
Why are aerobic cultures drawn before anaerobic cultures?
Aerobic cultures are typically drawn first because aerobic bacteria are more likely to be present in the sample and grow faster than anaerobic bacteria. This allows for quicker identification and treatment of potential infections.
Would you expect to be able to isolate an anaerobic organism from any of your cultures?
It is possible to isolate anaerobic organisms from cultures specifically designed to support their growth, such as anaerobic culture techniques that avoid exposure to oxygen. However, in cultures that are aerobically maintained, it would be unlikely to isolate anaerobic organisms due to their sensitivity to oxygen.
Why the live cultures are essential?
Live cultures are essential for promoting the health of intestinal flora. Our digestive systems have naturally occurring bacteria that help us digest. Sometimes this flora goes out of balance, like after taking a course of antibiotics, then we need to take in foods like yogurt that has live cultures.
I need to know what antibiotics should be taken for teeth pain. I know different antibiotics work for different parts of the body.?
Antibiotics are sometimes prescribed for tooth infections, but not for pain. The infecting bacteria will dictate the antibiotic to employ -- so one can't know until one cultures the infection. Antibiotics of choice for prophylacsis vary from one part of the world to another, so without a locale, this can't be answered either.
Why is it important to study about families from various cultures?
Studying families from various cultures is important to gain a deeper understanding of diversity, values, and traditions. It helps in promoting cultural sensitivity, empathy, and inclusivity in society. Additionally, it allows for the identification of commonalities and differences in family structures and dynamics across different cultures.
What is the purpose of plating out cultures?
Plating out cultures is done to separate individual bacterial colonies so they can be counted, identified, or studied independently. It allows for the isolation and identification of specific microbial strains present in a mixed population.
What is axenic culture?
Axenic culture refers to the growth of pure microbial cultures devoid of any other contaminating organisms. This is achieved by using sterile techniques and media to ensure that only the desired microorganism can grow. Axenic cultures are important for studying the characteristics and behavior of specific microorganisms without interference from other organisms.
