When a previouslyrics effective antibiotic stops killing particular kind of bacteria?
When a previously effective antibiotic stops killing a particular kind of bacteria, this phenomenon is known as antibiotic resistance. It occurs due to genetic mutations or the acquisition of resistance genes that enable bacteria to survive despite the presence of the antibiotic. Overuse or misuse of antibiotics in medicine and agriculture accelerates this process, leading to the proliferation of resistant strains. Consequently, treating infections becomes more challenging, necessitating the development of new antibiotics and alternative treatment strategies.

What other tests does a woman with mastitis undergo?
Tests can be performed to determine what type of antibiotic would be most effective against that particular bacteria.
What are resistant bacteria?
A property of some bacteria that have been exposed to a particular antibiotic and have "learned" how to survive in its presence.
Is it OK to take Valacyclovir with an antibiotic?
No. This is an antiviral medication and is not effective against bacteria.
When are antibiotics not effective?
An antibiotic might not work because the symptoms are attributed to a virus rather than a bacterium. Antibiotics do not work against viruses.
What do the sensitivity numbers mean on a urine culture and sensitivity test?
The sensitivity numbers on a urine culture and sensitivity test indicate the effectiveness of different antibiotics in treating a specific bacteria found in the urine sample. It helps determine which antibiotic will be most effective in treating the infection. The higher the sensitivity number, the more effective the antibiotic is against that particular bacteria.
What makes penicillin an effective antibiotic?

Is Streptomycin effective against gram?
Streptomycin is an antibiotic effective primarily against certain gram-negative bacteria, as well as some gram-positive bacteria. It works by inhibiting protein synthesis in bacterial cells. However, its effectiveness can vary depending on the specific strain and its antibiotic resistance profile. Therefore, susceptibility testing is often necessary to determine its effectiveness against a particular bacterial infection.
What is an A disk in microbiology?
You'd have to be more specific in your question. However, disks are often laden with antibiotics to see if a bacteria is resistant or susceptible to that antibiotic. The disk is placed on a nutrient agar and then bacteria is spread onto that disk. If the bacteria is susceptible to that antiobiotic, it will grow on the nutrient plate, but not around the disk containing the antibiotic. The larger the clear area around the disk, the more susceptible the bacteria is to that antibiotic. If it is resistant to that antiobiotic, it will grow on the plate and adjacent to the antibiotic laden disk indicating that antibiotic is not effective towards that particular bacterial strain. In one such test the A disk had bactracin. However, I am not comfortable saying that all A disks have bactracin. How the disk is labeled may differ.
An antibiotic is effective in killing 95 percent of a population of bacteria that reproduce by the process shown below which statement best describes future generations of these bacteria?
Future generations of these bacteria are likely to have a higher proportion of individuals that are resistant to the antibiotic due to natural selection. Over time, the resistant bacteria will survive and reproduce, potentially leading to the evolution of a population that is largely resistant to the antibiotic.
What is susceptible numbers on a culture and sensitivity test mean?
Susceptible on a culture and sensitivity test means that the bacteria being tested is vulnerable to the antibiotic being used. This implies that the antibiotic is likely to be effective in treating an infection caused by that specific bacteria.
An antibiotic that destroys a bacteria upon contact?

If a petri dish shows a large zone of inhibition what does this say about the antibiotic?
A large zone of inhibition on a petri dish indicates that the antibiotic has effectively inhibited the growth of bacteria surrounding the disc. This suggests that the antibiotic is potent against the bacteria being tested, as it can effectively prevent their growth. A larger zone of inhibition usually indicates a higher concentration of antibiotic or greater efficacy against the bacteria.
