culture and sensitivity
The name given to cultures for the identification of organisms as well as the identification of sensitivities of the organism to antibiotics is "microbiological culture and sensitivity testing." This involves growing the organism in a culture medium to identify it and then testing it against different antibiotics to determine which ones are effective.
Antibiotics in the person's system may prevent microorganisms present in the sputum from growing in culture.

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.
These organisms can then be grown and identified in the laboratory so that the proper antibiotic can be given to the patient.
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.
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.
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.
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.
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.
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.
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.
