不同点：germ和bacteria的区别就是前者都是指有害的细菌，而后者包括所有有益的细菌和有害的细菌。二：用法区分 germ 是普遍意义上的 “细菌” （通常是日常用）； bacteria 是医学术语上的 “细菌”。三：典型例句 1、germ ——Our immune systems are killing billions of germs right now.我们的...
Bacteria(细菌)are extremely small living things.While we measure our own sizes in inches or centimeters, bacterial size is measured in micron.One micron is a thousandth of a millimeter; a pinhead is about a millimeter across.Rod-shaped bacteria are usually from two to four microns long, while...
are resistant to initial β-lactam empirical therapy. Furthermore, α-haemolytic (or viridans) streptococci have become more important as they sometimes cause an aggressive syndrome, the so-called ‘toxic strep syndrome’, and there is wide-spread penicillin resistance (15–50%) among these ...
Meanwhile, there are no significant effects on the bioactivities of the coated bacteria since the coating membrane is eventually removed during cell division of bacteria. Compared with uncoated bacteria, CMCB achieve (1) ~14 times higher blood reservation 48 h post-injection; (2) a lower ...
autoinducers, orpheromones. The concentration of quorum-sensing molecules—most commonlypeptidesor acylated homoserine lactones (AHLs; special signaling chemicals)—is related to the number of bacteria of the same or different species that are in the biofilm and helps coordinate the behaviour of the ...
Lactic acid bacteria are characterized by several unique properties. As their name implies, a major by-product of their metabolism is lactic acid. Depending on the genus and species, lactic acid bacteria ferment sugars solely to lactic acid, or to lactic acid, ethanol, and carbon dioxide. The...
Petagrams of dimethylsulfoniopropionate (DMSP) are produced annually1by marine algae, corals, plants, and heterotrophic bacteria2. In these organisms, DMSP is proposed to act as an osmolyte, cryoprotectant, predator deterrent, and/or antioxidant3,4,5. DMSP is synthesized from methionine (Met) vi...
Addressing the issue of virus mutation at the press conference, Wang Dayan, head of the Chinese National Influenza Center under the Chinese Center for Disease Control and Prevention, said the situation is being closely monitored. "The results have shown that the antiviral drugs in use are effectiv...
Since virtually all carbohydrate catabolic genes or operons are regulated by specific control proteins and require inducers for high level expression, direct control of the activity of regulators or control of inducer formation is an efficient measure to keep them silent. By these mechanisms, bacteria...
Blackberries are one of our most common plants. They grow in the countryside, gardens, parks and even on waste ground in the middle of cities. The bushes are green all the time and have toothed leaves. But the most important thing to remember about a blackberry bush is that those branches...
