Some of the unique and unbelievable facts about microorganisms which i have collected from various authentic sources.it’s makes me more interested in the field of microbiology .
1.Bacteria can be found everywhere, hot springs to arctic regions. in our( human )mouth contains more than 500 species of bacteria. Each square centimeter of your skin averages about 100,000 bacteria.
2.The smallest known bacteria are so tiny that they were once thought to be viruses (Mycoplasma).
3.Deinococcus radiodurans: withstand blasts of radiation 1,000 times greater than would kill a human being.
4.The largest bacteria found so far can actually be seen without the use of a microscope (Thiomargarita namibiensis and Epulopiscium fischelsoni).Thiomargarita namibiensis , which means “sulfur pearl of Namibia” is a single celled giant bacteria that lives in the ocean.
5.Beef tapeworm is the largest parasite (which causes taeniasis in human), which can easily grow 7½ meters or 25 feet long! Imagine that living in your guts
6.Microbes generate at least half the oxygen we breathe.
7.You are more likely to be struck by lightning that to be eaten by a shark. You are more likely to be infected by flesh-eating bacteria than you are to be struck by lightning.
8.Researcher’s revived a 250 million old bacterium, Bacillus permians that were discovered from salt crystals.
9.Diamonds are thoughts to be made from carbon and dead bacteria.
10.All the bacteria in our body collectively weigh about 4 pound(1.814kg)
11.The smell of rain is due to bacteria called Actinomycetes.
12.Researcher’s found that 1458 new species of bacteria’s in belly button of human being.
13.Sweat itself odorless. microbes mingle with sweat and produces odour
14.While kissing,exchange of 10 million to 1 billion bacteria.
15.Most antibiotics in world are made up of bacteria.
16.Babies are born with no bacteria’s in their body.
17.There are viruses that infect bacteria (bacteriophages).
18.Yeast is a single-celled fungus, and is used to make bread rise, and to produce alcohol by fermentation in beer, wine and cider (see ‘Make Yoghurt and Grow Yeast’).
19.Fungi helps organic materials break down in the compost bin(decompsers).
20.Lichens used to be used to dye fabric and wool.
21.The blue veins in Stilton cheese and other blue cheeses, and the white rind on Brie and Camembert are fungi (and it makes them taste very good).
22.Bacteria are used to clean water in sewage plant & they can also helps to clean up oil spills.
23.Viruses are simpler than bacteria, made up of genetic code (DNA or RNA) with a protein shell – some scientists do not describe them as being alive.
24.There is no vaccine against colds, as there are so many different viruses that cause colds.
25.Flu vaccines change every year, as there are a number of different flu viruses, and the viruses themselves mutate (change) all the time.
26.The more people who are vaccinated reduces the amount of infection in a population, protecting even those people who are not vaccinated – this is called ‘herd immunity’. Depending on the virus, 85-95% of people need to be vaccinated to protect the rest of the people – this is why vaccination is important.
27.Most viruses cause diseases are: – colds and flu are caused by viruses, as well as common diseases like chickenpox, measles, mumps and German measles (rubella). HIV, which causes AIDS, is a virus.
28. Viruses are not alive: They do not have cells, they cannot turn food into energy, and without a host they are just inert packets of chemicals.
29. That über-virus is now called Mimivirus, so named because it mimics bacteria and because French biologist Didier Raoult, who helped sequence its genome, fondly recalled his father telling the story of “Mimi the Amoeba.”
30.Some parasitic wasps lay eggs in caterpillars, where they mature into adult wasps. The wasp eggs contain a virus, encoded in the wasp genome, which prevents the caterpillar from rejecting the eggs.
31.Earwax has antimicrobial properties that reduce the viability of bacteria and fungus in the human ear.
32. Honey is a natural reservoir for the Botulism bacteria. Adults can normally process it and infants can’t and this is why you shouldn’t give babies honey.
33. Magnetospirillium magneticum is a free-living bacteria which has the ability to actively take in iron, convert it to magnetic magnetite, align it like a backbone along its body, and travel through its environment using magnetic fields.
34.Millions of people don’t actually need to use deodorant (especially East Asians) because they have a gene (ABCC11) that stops them from producing sweat that attracts body odor causing bacteria. People with “dry earwax” have this particular gene.
35.Bacteria are present in clouds and they make better nucleators to start snow/rain better than dust.
36.In 1950, the US Navy filled balloons with a certain type of bacteria and burst them over San Francisco. “Operation Seaspray” was intended to study wind currents that might carry biological weapons. Shortly thereafter doctors in the area noted a drastic increase in pneumonia and urinary tract infections.
37.The white, bad smelling chunks that you find in your mouth are not bits of food, but hardened sweat and bacteria from your tonsils.
38. Human breast milk contains sugars (oligosaccharides) intended to feed intestinal bacteria, rather than the infant itself.
39.Bacteria ferment the beans that end up making chocolate and coffee, and they help make vinegar. They’re used in mining to eat through rock. They can repair concrete and create other building materials. They can even be made into a sustainable packaging material. They can detect pollution and find land mines. They clean up oil spills and nuclear waste. They can be used in pest control and maybe, someday soon, as energy for batteries.
40.There’s a species of bacteria so resistant to radiation that scientists have nicknamed it “Conan the Bacterium”
41.The amount of bacteria on a pair of jeans doesn’t increase after about 2 weeks of wear. The study had the test subject wear the jeans non-stop for 15 months, and still it didn’t develop an unhealthy amount of bacteria.
42.Drying your hands with paper towel will reduce the bacterial count by 45 – 60% on your hands. However, using a hand dryer will increase the bacteria on your hands by up to 255% because it blows out bacteria already living in the, conveniently, warm moist environment.
43. Some Civil War soldiers had wounds that glowed in the dark because of a bioluminescent bacteria that was puked up by nematodes. These bacteria actually killed off other pathogens and made the survival rate of those soldiers higher.
44.To treat bladder cancer, one of the lesser known methods of treatment practiced by doctors is to inject weakened bovine tuberculosis bacteria up your urethra. The subsequent immune reaction destroys cancer cells. This treatment has been shown to be more effective than chemotherapy.
45. The discoverer of penicillin Alexander Fleming warned even as early as 1920s about the possibility of antibiotic resistant bacteria due to antibiotics misuse.
46.Kangaroos barely release any methane. Scientists are therefore trying to harvest the bacteria found in their colons so that they can transfer this “skill” to cows to greenhouse gases emission.
47. Unwashed eggs still have their protective coating, the bloom, and are safe to store on the counter. Many modern countries wash eggs before sale so they ‘look’ cleaner and safer, but this opens the pores of the shell for infection from bacteria during storage time.
48.A group of scientists transcribed the song “It’s a Small World After All” into the DNA of a bacteria that is resistant to radioactivity, so that in the event of a nuclear catastrophe, we could pass a message on to future intelligent life.
49.The “smell” of rain after a storm is produced by the same type of bacteria that causes water to taste “earthy”.
50.Human bites are one of the most dangerous animal bites in the world due to the bacteria in our mouths.
