Bacterial cells can generate antibiotic resistance by two preferred method: first is via mutations that happen while replication in the cell's DNA and second is bacteria achieve tolerance by horizontal transmission of genes. Few bacteria have sufficient immune and naturally due to an extremely impermeable cell membrane or absence of target that is selected by the antibiotics. Other bacteria may produce enzymes which may inactivate antibiotics on having any communication.
In certain cases, bacteria may alter the target of the antibiotic, making the antibiotic unsuccessful. The organic protection of the body are extremely successful in fighting off such oral infections and in controlling inflammation. The study found that antibiotics killed the favorable bacteria, which reduced the development of SCFAs (short chain fatty acids) and impaired the capacity of white blood cells to combat fungal infections, like Candida.
