Stories like this have cast phages as a miracle cure.And these tiny viruses do have a lot of things going for them. They target bacteria with stunning specificity. “We think of phage as a targeted missile,” says Daria Van Tyne, an infectious disease researcher at the University of Pittsbu...
Many people are in the fight against both seasonal and the H1N1 virus. The weather is cold and rainy. It expedites the spread of viruses. Here are several effective ways to guard against the flu, without the need for a vaccine or buying expensive medicines. Wash Your Hands. Most flu ...
预计到2050年,抗菌素耐药性每年将导致1000万人死亡,高于2019年的100万人左右。 It would be unwise to rely on new antibiotics to solve the problem. The rate at which resistance emerges is accelerating. Some new drugs last only two years before bacteria devise countermeasures. When new antibiotics do ...
However, there is some skepticism surrounding all of this technology and how it actually helps. While many do stand to benefit, some researchers have pointed out that potential blind spots in data aggregation can leave underrepresented areas at greater risk for Coronavirus to spread. Alongside that,...
where there are many activities in the human body that need water to regulate. Drinking more water to ensure that the respiratory mucosa is moist, weaken the propagation rate of cold and other viruses. To a certain extent...
Lymphocytes are different from the other WBCs because they can recognize and have a memory of invading bacteria and viruses. Lymphocytes continually pass back and forth between lymph tissue, lymph fluid and blood. When they are present in the blood, they stay for several hours. Lymphocytes can ...
Theimmune systemidentifies these foreign substances (virusesand bacteria), also known asantigens. Once antigens are identified, the immune system develops proteins that circulate in theblood. These proteins are calledantibodies. They fight the infection by killing the antigens. Antibodies are made by...
When you receive (接受) a vaccine, you are given the bacteria or viruses that caused (导致) a disease. But the bacteria or viruses in the vaccine are dead (无活力的) or weakened (减弱的). So your white blood cells are able to (能够) make antibodies to fight (战胜) the disease, an...
living organisms. They are infectious agents with only a protein shell and a strand of RNA or DNA, depending on the type of virus. They do not reproduce on their own—like bacteria do. Instead, viruses need a host cell to do the reproducing for them (you’ll learn more about that ...
