How might a capsule contribute to pathogenicity? User: how might a bacetrial capsule contribute to pathogenicity?
Weegy: The motion of the rotating flagella helps bacteria swim to reach the site where they can survive, and for that reason flagella can contribute to pathogenicity. User: of what advantage to Clostridium is an endospore? Weegy: The same advantage it is to any bacterium. It's a thick walled cell that allows the bacterium to remain dormant in times of stress without dying. [ ] User: You can see endospores by simple staining. why not use this technique (More)

Why was the arrangement of Lactococcus from the broth culture and slant culture different in the second period?
Weegy: The broth culture grow many bacteria within a small area (they would b close together). Where as on the slant plate there is a little more room for the bacteria to grow so there arrangement would be different. User: For a bacterium, what is the evolutionary advantage to forming of a pellicle in a liquid medium? Weegy: I would think that in a liquid medium the bacterium would like to help retain form/shape,because that what a pellicle is a a thin layer supporting the cell embrane. [ so if a bacterium in a liquid medium not evolved an effective way to continue surviving thus thriving in its environment it might just cease to exist an evolutionary dead-end. ] (More)

do all bacteria ferment lactose? User: e. coli and enterobacter aerogenes are small gram negative rods. how can you differentiate them?
Weegy: These two bacterial species are identical in many superficial ways. They both produce white colonies at 37 degrees Celsius on nutrient agar. They both ferment lactose producing acid and gas. [ They are both Gram negative and virtually identical microscopically. To distinguish them we must resort to biochemical tests. They metabolize sugars and other organic compounds, like Citrate, differently. Below are some of the tests we do to distinguish E. coli and E. aerogenes. Note how clearly they differ when we use biochemistry to tell them apart! Below on the left E. coli and Enterobacter aerogenes are growing on the surface of Eosin-Methylene Blue Agar. There is glucose in this medium which both bacteria metabolize. But they both produce different byproducts. E. coli produces a byproduct of glucose metabolism which reacts with the basic dyes in the medium producing a "green metallic sheen" in reflected light. Enterobacter produces normal colonies. The EMB test differentiates between E. coli and E. aerogenes sharply. ] User: Why Are Fermentation Tubes Evaluated at 24 and 48 Hours (More)

Weegy: Assuming the organism is in a very confined container (not closed), then the organism will have to find an external source of fuel (food), otherwise with no food the organism will die. [ This correlates to the amount of gas produced by the organism, the more food the more gas, once all food is gone no more gas will be produced ] (More)
