They are microbes. They are very small and can be easily confused. However, bacteria and viruses are two completely different things. And to effectively fight those who cause the disease, it is better to clearly identify them.

The Sun Constant and exceptionally scorching temperatures allowed the breeding of extremely dangerous organisms in the stagnant waters of France: lakesPonds and ponds, both in the south and north, have seen the spread of cyanobacteria, also called “blue algae” or “blue-green algae”. In recent days, several dog deaths have been reported in France and Switzerland. The animals were bathing or playing in the water when they were taken away seizures.

In the most serious cases, some children and adults have been hospitalized in intensive care after swallowing contaminated water while swimming in recent years. Of the thousands of species of cyanobacteria that exist, about forty are dangerous and none are antitoxin for them toxins. Repeated exposure to these bacteria, for example bathing in a polluted lake every year, may result in organ damage that will not be discovered until many years later.

The ideal weather conditions for its spread at the moment

the conditions weather report It is currently considered ideal for the reproduction of cyanobacteria, because these organisms solar energy conversion in energy Chemicals. How do you know if a water point is contaminated? Infested lakes and ponds are often cloudy, with a somewhat colored gelatinous layer on the water, yellow or brown, which sometimes emits an unpleasant odor.

waters rivers, with current, represents less risk. But it is not always easy to detect their presence, and it is advisable not to bathe in stagnant water in case of extreme heat, except for those that are controlled and therefore allowed to swim.
