a: Bacteria ~
b: shark

What: "You may think that good hand hygiene before every crime would protect you but you'd be wrong. The roughly 150 different species of bacteria on our hands replenish themselves quickly after a good hand washing. You wouldn't want to get rid of them either. Bacteria are like sharks. A small percentage of them will eagerly bite your head off but the vast majority are harmless, even beneficial."

a: Bacteria ~
b: little DNA factories

What: "Bacteria are like little DNA factories," she explains. "You always need a supply of stock DNA to work with." Her job included growing colonies of bacteria, then purifying the DNA from it. The DNA was sometimes injected into the cells of mice to see how altering a gene affected their development, so Sunny had to tend large colonies of laboratory mice, a task that did not thrill her. "Lab mice are not very sweet," she says. "But I guess I can't blame them."

a: Bacteria ~
b: fingerprints

What: "Bacteria are like fingerprints. Once you are born with them, they never change. Around 80 per cent of the bacteria in your gut were transmitted from your mother during birth. The bacteria in your system today are roughly the same composition as the bacteria that lived there when you were an infant."

a: Bacteria ~
b: blind people

What: "In a way, bacteria are like blind people. They don't have hands, but they do have tiny receptors on their "skin" (cell membrane) that can bind and sense sugar."

a: Bacteria ~
b: computer

What: "Now that we know the complete DNA sequences of hundreds of different bacteria, we can see that nearly all these diverse functions are carried out by "accessory genes". Bacteria are like computers: they have a "basic genome" that keeps the system running and is much the same in all bacteria, rather like the hardware and operating system of a computer. Then there are sets of accessory genes that provide special adaptations, and over time each bacterium acquires a unique collection of these by swapping with other bacteria, just as computers accumulate software packages and data."

They Should Be There And Be Healthy

a: Bacteria ~
b: wolves in Idaho

What: "Gut bacteria are like wolves in Idaho. If you don't bring in new wolves and stop hunting them, you never again have wolves in the wilderness. If you don't bring in new bacteria and feed them, damaged gut flora does not repair. Antibiotic treatment that wipes out the bacteria needed for development of the suppressive immune system will lead to autoimmune disease."

Why Some Stain Well And Others Don't

a: Bacteria ~
b: metal wall

What: "Imagine you're painting a wall -- normal housepaint will stick well to a primed drywall surface, but it won't stick well to a shiny metal surface. So, by analogy, some bacteria are like the metal wall, and some are like the drywall. And therefore, some bacteria are dyed more strongly than others."

a: Bacteria ~
b: living paint

What: "Bacteria are like living paint, covering nearly every surface imaginable and living within other living and nonliving things. Many exist in a symbiotic condition in which they function as partners with other organisms."

What: "Bacteria are like the stage hands that allow the show to go on without being seen (or always given the credit)"

a: Bacteria ~
b: insects

What: "Bacteria are like insects. Some are useful even essential. Others are so harmful they can wipe out an entire population."

a: Bacteria ~
b: Popeye

What: "Popeye the sailor man and infection-causing bacteria have something in common -- they need to consume iron to perform their best. In cartoons, Popeye gets his iron from spinach. New research shows exactly where the bacteria that often cause pneumonia get their iron. Here's a hint, the iron doesn't come from spinach."

a: Gut bacteria ~
b: mean drill sergeants

What: "This works because the bacteria essentially train the immune system in early childhood to not react to harmless antigens. Antigens- typically toxic or infectious-are like little invading troops in your body. In this extended metaphor, gut bacteria are like the mean drill sergeants making your immune system do pushups in the mud because someone sneezed near you."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
