bacteria

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."

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."

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."

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."

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."

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."

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."

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: "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."

Bacteria is unicellular
Human cell is unicellular
Bacterial cell = human cell
Bacteria as a friend of human = an internal human cells are friends of human
Bacteria as an enemy = sometimes some internal cells transform in to tumour cells
Bacterial infection is like a foreign invasion = internal invasion is like civil war a fight with its own community but very powerful
Bacteria can reproduce = cell can reproduce
Bacteria can die = cell can die
Bacteria has DNA = cell has DNA
Bacteria has membrane or external shield = cell has external shield but less strong
Bacteria has community or colony = cell has colony or tissues
Bacterial culture can be done = cell culture can be done
Enterobacter (bacteria of gut ) = cells of git (but opposite function one kills while others work for git )
Alveolar bacteria (bacteria that infect lungs ) like pneumococcus = alveolar macrophages
Meningococcus (infects nerves ) = neuroglia cells that protect nerves
Erythrocytes infected by bacteria

Weapons
Leucocidin (produced by bacteria to kill ) leukocytes
Erythrotoxin = kills erythrocytes
Pneumolysin = kills pneumocytes
Enterotoxin = kills enterocytes

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."
