Similarly, the increasing number of mosquitoes becoming resistant to insecticides, the presence of insects in cities that are changing their resistance to and adaptation to cleaning products which is used to solve it. This has been revealed by scientific research, which has also discovered new types of parasites in cities like Hong Kong that were previously found in Antarctica.
After the recent Covid 19 pandemic, The use of pesticides has increased, but it is ineffective these efforts to create an urban environment?

A study published in the journal ‘Microbiome’ has found Microorganisms that have evolved to survive even on the limited resources available in the cities. Research has also shown that our daily habits are changing the composition of microorganisms in indoor environments.
Scientists have discovered new types of pathogens that have adapted to the limited resources found in cities.
“Built areas offer unique characteristics that distinguish them from natural and man-made environments,” said Xinzhao Tong, associate professor at Xi’an Jiaotong-Liverpool University (XJTLU), China, and lead author of the study.
Built-up environments lack essential nutrients and nutrients that microbes need to survive, so these built-up environments have unique microbiomes.
«Using cleaning products and other similar products creates an environment that forces viruses, which they fight against should be changed or removedbut the mechanisms by which pathogens adapt and survive in built environments are poorly understood,” explains Tong.
The researchers collected 738 samples from a variety of built-up areas such as subways, residential buildings, public spaces, docks and public skin in Hong Kong. They then used metagenomic sequencing to analyze their genomes and understand how they have adapted to complex urban environments.
They wash off the ingredients in the cleaning products
The result is that our bodies are this new type of Eremiobacterota it allows you to use ammonium ions found in cleaning products. In addition, the species also contains genes for alcohol and aldehyde dehydrogenases to eliminate residual alcohol from pesticides.

“Microorganisms that can use less resources and tolerate things like pesticides and metals, They defeat the unconquered nations, thus improving their lives and its evolution in the built environment. “So, they can pose a risk if they have an infection,” adds the expert.
The team identified 11 unique types of Micrococcus luteus He was not found until thenwhich usually do not cause disease, but can cause opportunistic infections in immunocompromised individuals.
Worrying about hospitals
«The question depends on our behavior It is especially important in hospitals, because hospitals are hotbeds of various diseases. which causes hospital-acquired infection (HAI). “HAIs carry a high risk, especially in intensive care units, where the mortality rate is as high as 30%,” says Tong.
Researchers He also discovered two new species of Patescibacteriacalled ‘nanobacteria’since they have small genomes that do not have many genes to make their own products.

Tong explained: “Some things about Patescibacteria They are considered parasites, because they depend on parasites for their food. However, in this study, the researchers found that one type of nanobacteria, which comes from human skin, contains genes for carotenoid and ubiquinone biosynthesis.
“These antioxidants are essential for humans, and we usually get them through food, meaning a possible cooperation between bacteria and us as their hosts».
