Where in the house are the germs and how to fight them?

house dust can tell a lot about your personality

Even when you think you are left alone at home it is not. And it's not about the dog, cat or aquarium fish, but of billions of tiny roommates. Some are harmless, others useful, but there are those that can – in the right concentration and in the wrong circumstances lead to your death. Bacteria, viruses and fungi, whether you like it or not, are on you, around you and deep within you. The fact that bacterial life does not surprise anyone, but the photos of the germs under a microscope, all the same, is a concern. Especially when you realise that they are settled on your doorknobs, favorite mug, and even a sponge for washing dishes. In this article, you will learn where in the house inhabited by germs and what to do with it.

Where are the germs?

Scientists are increasingly beginning to appreciate the wealth of the so-called microbiome – the microscopic or, in the case of viruses, submicroscopic ecosystem as complex as those encountered in oceans, tropical forests and deserts. The microbiome is you and your home and in most cases it's good intestinal bacteria, living in harmony with you, you can strengthen your immune system, help digest food and even protect against certain diseases. And yet it would be nice to know these tiny creatures better.

To this end, researchers from North Carolina state University led by biologist Rob This, the head of the project called «« in 2012 and 2013 had a number of microbiological expedition to the homes and apartments of people trying to find new forms of life, to identify friends and find out which ones live where, and why. Scientists also wanted to find out how each type of bacteria affects us, interacting with our microbial ecosystems and perhaps even joining them in our guts.

Writes , microbiological expedition has turned into templates and sent to participants by mail. In the kit was sterile cotton swabs for wiping the six areas selected for the reason that Dunn and his colleagues suspected that they will represent several different ecosystems: the computer screen, a door handle, toilet seat, kitchen counter, and pillowcase. The subjects were asked to complete a questionnaire about themselves and their habits, including cleaning products they use, and the presence/absence of Allergy. The samples, sealed in plastic bottles, the study participants were sent back to North Carolina.

Three ecosystems of your home

The Results of each individual «expedition» have been stated by the researchers in the table that lists over 1400 different bacteria identified by DNA. Biologists have placed the names of the bacteria so that they show the inhabitants of the three places representing the three most common household ecosystems: the kitchen, the door handle and the bed.

On the doorknob subjects living near green areas was predictable the most common bacterial DNA plants. Chloroplasts – structures which allow plants to extract energy from photosynthesis, were originally free-floating cyanobacteria, which live in plant cells. But the detected DNA of cyanobacteria is a sign of pollen.

Near the chloroplasts located skin bacteria, including the genus Corynebacterium (including diphtheria bacterium). Earlier in 2010, researchers from the Worcester Polytechnic Institute in the United States of 1.32 thousand bacterial colonies on 27 doorknobs at the University campus.



With regard to microorganisms in the bed, in most cases, the pillowcases were discovered more skin bacteria than the intestinal or fecal. This is good news, but we must not forget that the fecal germs are everywhere and constantly apply. This contributes to a large number of people who do not wash their hands after using the toilet.

So under the microscope looks dust mite

And here are the results of 2016 are not so optimistic: as it turned out, in 5-8 years, the use of a mattress stored in it at least 45 kg skin Horny scales, and it's not talking about disputes of fungal and dust mites.



Kitchen bacteria, in turn, was 40% related to plants or products. Recall that earlier scientists that the surface of the wooden cutting boards lives in 200 times more germs than the toilet rim. Do you think what kind of bacteria live in your home? Response

The Results from another study that sponge for washing dishes – most are biological weapons, if not to change them once a week: because of the high humidity and constant contact with food debris in the pores of a foam sponge formed colonies of microorganisms. Moreover, the National science Foundation (NSF), 86% of sponges and rags showed positive for yeast and mold. the E. coli detected in 75% of the samples, in 18% of staph.

How to fight germs in the house?

As if terribly exciting and exciting as it is to discover what organisms live near you and within you, it is important to understand that the human immune system is a highly developed machine to kill bacteria. Often the body enters into a mutually beneficial truce with the microbes from the outside. Biologists believe that the microbes that colonize us can train and toughen the immune system. At the same time, bacterial imbalance can cause the development of autoimmune diseases.

Anyway, to not fall victim to the Salmonella, pathogenic E. coli, coronavirus, hepatitis A and other not less pleasant germs in the first place it is necessary to properly wash hands. On how to do it correctly read in Ramis picture. As for cleaning, then change foam sponges once a week, wooden cutting boards once a month and carefully wash the toilet and bathroom.
