In pure sponges for dishes there are more microbes

German doctors and microbiologists conducted a study on the microorganisms inhabiting sponges for washing dishes. What pathogens are found in the sponges and why attempts to disinfect lead to the opposite result, the scientists said in an article in the journal Scientific Reports.
Sekvenirovanie DNA of microorganisms of the 14 used sponges, the study authors calculated that one cubic centimeter of sponge lives about 5×1010 bacteria — seven times more than people on Earth. Among the microorganisms encountered and related quite dangerous for the bacteria that causes meningitis and pneumonia. One of the microorganisms Moraxella osloensis, may cause illness in people with a weakened immune system, but at the same time “responsible” for its characteristic odor sponge.
The unexpected conclusion was that boiling or heating in a microwave oven does not kill all germs. In contrast, in sponges, which regularly conduct these operations, there are more microorganisms that can cause harm to humans. Perhaps this is due to the fact that pathogens are more tenacious and only benefit from the death of less-resistant bacteria.
