First treatment raw penicillin – bactericidal effect discovery
First treatment raw penicillin – bactericidal effect discovery – In 09.01.1929 in London first applied
treatment raw penicillin. Bactericidal effect of mold penicillinum discovered Sir Alexander Fleming.
Human body bacteria – weight of digestive tract microorganisms
Human body bacteria – weight of digestive tract microorganisms – The total weight of bacteria
living in the human digestive system is approx. 1.5 kg. In the large intestine,
we have 100 trillion microorganisms. 10 times more than the number of all cells in the body.
They are divided into roughly 400 species.
Studies have shown that it is the changes in the number and species of bacteria in the gut
have a negative impact on the psyche of the patients. According to specialists bacterial flora
may be responsible not only prone to depression, but depression symptoms in themselves.
At one cm square elbow stays on average 10 thousand. bacteria – 113 different species,
but more than 90% are 10 of them. The least bacteria on human skin found between the toes,
the largest habitat of the navel.
Antonie van Leeuwenhoek – first microscope creator
Antonie van Leeuwenhoek – first microscope creator – In 24.10.1632 was born
the Dutch naturalist A. van Leeuwenhoek, considered the creator of the microscope.
As the first saw the human sperm. It is assumed that described many of anatomical structures and
organisms and bacteria discovered and disproved the theory of spontaneous generation.
Bacteria under ocean bottom
Bacteria under ocean bottom – American geologists from Oregon, performed in Atlantic oceanic crust (where the temperature is approx. 102 ° C) drilling to a depth of 1,391 m. Among granitic igneous rocks found relatively rich bacterial ecosystem. Bacteria feed on methane and benzene there.
Ions against allergy
Ions against allergy – Ion generator in the car helps allergy sufferers – positive charges associated dust mites, molds, fungi, viruses and bacteria. Dust as a result of the charge becomes heavy and sinks. In their cars ionizers factory manufactures Lexus and Infiniti. The sales are also portable ionizers.
Bacteria in human body
Bacteria in human body – In the body of an adult human lives approx. 500 trillion of different bacteria, which is a lot more than your own body cells. Fortunately, most of these microorganisms are harmless.
Extremely small genome
Extremely small genome – The genome of Haemophilus influenzae was the first in the history of the genome was read. This took place in 1995. This bacterium was chosen due to its extremely small genome, which contains only 1 830 140 base pairs of DNA and genes 1740.
Antibiotics – deregulate the immune system
Antibiotics – Approx. 70% of infections are caused by viruses. Antibiotics only fight bacterial infections, and often adopted deregulate the immune system.
Antibiotic treatment causes changes in the intestinal microflora, which persist for several years. Today we can not fully predict the consequences of these disorders, but we know that certain types of beneficial bacteria after antibiotic treatment are lost forever
– warns gastroenterologist Dr. Marlicz.
Earth Bacteria – quantity in one kilogram of soil
Earth Bacteria – All over the Earth is approx. 5 x 10³º bacteria, while one kilogram of soil there are an average of 40 million.
Human Microbiome Project – HMP
Human Microbiome Project – The first results of the Project on Human microbiome (Human Microbiome Project – HMP) are amazing. The genome of microbes more than 8 million protein-coding genes. In the human and just 22,000. In human bodies inhabited by about 10,000 species of bacteria. Each person “carries“ approx. A thousand species. It is not known until the end of what’s going on in these differences between individual “loads” of microbes, but it seems that the more species we have in ourselves, that we are healthier.
