The population of bacteria that live in the female vagina undergoes continuous changes, both in the type and abundance of microorganisms, according to a US investigation published this week in the journal Science Translational Medicine.
A low production of saliva causes bad breath or halitosis due to stagnation of food and of the saliva itself. Stagnant saliva undergoes a process of putrefaction and increases the pH of the mouth. With a pH equal to or greater than 7.2, the growth of certain gram-negative bacteria that are capable of breaking down protein or fatty foods increases.
The United States military has developed a sandwich that fights bacteria and fungi and keeps "fresh" for up to two years. To achieve this, a team of researchers at the Natick Soldier Research, Development and Engineering Center has used a three-pronged strategy: lower the pH, bind the water to another element so that microbes cannot use it, and add water filings to the wrapper. Iron that trap oxygen so it is not available for bacteria, yeast, and fungi to grow.
About 40% of the natural orange juice consumed in Spain is prepared in bars and restaurants, but according to a study by researchers from the University of Valencia (UV), the improper handling of oranges and the lack of cleanliness of the devices used During the process they favor bacterial contamination of the product.
A study from the University of Copenhagen (Denmark) reveals that the fewer the number of bacteria that live in our intestines during childhood, the greater the risk of allergies as we become adults. This implies that babies who are born by natural birth and who are therefore exposed to bacteria from the maternal rectum, have a lower risk of asthma and allergies than those born by cesarean section.
Thomas Glass and his colleagues at the University of Oklahoma (USA) recently published a study in the journal 'General Dentristry' showing that both brass and woodwind instruments are contaminated with a wide variety of bacteria and fungi. , many of which are associated with infectious and allergic diseases, as well as the development of asthma.
The shower head provides a dark, humid and warm environment that is ideal for microbes to grow, and when the tap is turned on, it carries away these potential pathogens and releases them in the form of aerosols, which are easily inhaled and enter the lungs.
Did you know that when you get out of the shower, the bacterial population on your skin goes from 150,000 to 6,000? And how many microbes are there on the computer keyboard? Discover this and other curious figures about specks of dust, germs, excrement, ...
