What are antibiotics and what do they do, if your child has a cold, antibiotics aren’t the answer. because millions of bacteria are needed to continue the disease process, these antibiotics can stop the infection and give the body’s own immune system time to attack. as powerful as antibacterials are when used in the right situations, they cannot kill viruses and do not work against viral infections. good news is healthy people who take infrequent, short courses of antibiotics usually recover quickly. some antibiotics come as ointments and others come as drops (eg, for ear infections). despite their size, viruses can cause mild and serious diseases when they enter healthy cells in the body.
Antibiotics how do they workpowerful and useful as antibiotics can be, they may produce side effects in some people. they attack the disease process by destroying the structure of the bacteria or their ability to divide or reproduce. they also cause smallpox, the measles, the mumps, hepatitis, and acquired immunodeficiency syndrome (aids). seek out bacterial cellshave you ever wondered how antibiotics kill invading bacteria, while leaving human cells alone? other times opportunistic infection begins when antibiotics disturb the balance of your resident microbes, and normally friendly bacteria multiply too quickly and become harmful. bacteria and human cells also differ in the structure of their cell membranes and the machinery they use to build proteins or copy dna.
some youngsters have an allergic reaction to penicillin and other antibiotics, producing symptoms such as skin rashes or breathing difficulties. indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or dna replication. when antibiotics kill too many friendly bacteria in the intestine, c. order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. since proteins do all the cell’s work, a bacterium that cannot build proteins cannot survive. they’re responsible for the common cold, the flu, and most sore throats and coughs.
bacteria help keep you healthy in many ways, so when antibiotics kill friendly bacteria, your health can suffer because you lose these benefits. if they’re given to your child when she has a viral infection, they can not only cause side effects, but also add to the serious problem of antibiotic resistance. penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. despite their size, viruses can cause mild and serious diseases when they enter healthy cells in the body. they live on our skin, in our digestive system, and in our mouths and throats., if your child has a cold, antibiotics aren’t the answer.
