Do bacteria lose resistance over time?

Can bacteria lose their antibiotic resistance? Yes, antibiotic resistance traits can be lost, but this reverse process occurs more slowly.

What is the first antibiotic?

But it was not until 1928 that penicillin, the first true antibiotic, was discovered by Alexander Fleming, Professor of Bacteriology at St. Mary’s Hospital in London.

How are laboratories used to determine which antibiotic to use?

In some cases, laboratories may help to decide which antibiotic to be used. Special techniques such as Gram stains may help narrow down which species of bacteria is causing infection. This is because certain bacterial species will take a stain while the others will not. Cultures may also be obtained.

What kind of bacteria can you kill with antibiotics?
