In the field of health science nowadays Antibiotic-resistance microbes are the leading health concern worldwide. Most notably some of the microbes are most superior known as Superbugs. They are able to resist nearly all type of antibiotics.

Predominantly this type of infection is the principle concern in Hospitals. Around five percent of the hospitalized patients are suffering from this infection while the staying period for medical supervision. Therefore researchers around the world are urgently seeking for the cure to prevent this type of superior Antibiotic-resistance microbes.

Regarding this, researchers are studying the origin and analyzed the evolution of Antibiotic-resistance which is crucial for finding the cure. Nowadays, one of the Antibiotic-resistance microbes known as Enterococci is used to study and analyzed the genomes and behavioral characteristics.

According to the study, researchers are able to discover the oldest predecessor of Enterococci and learn about the evolution of this organism. Therefore it will help to predict how Antibiotic-resistance microbes withstand the antibiotics and other products intended to control their spread.

Regarding this, a news report related to Antibiotic-resistance microbes released in the Massachusetts Eye and Ear portal. Bacteria first arrived nearly 4-billion-years ago and animals first appeared in the sea region in 542-million-years ago after Cambrian Explosion. However, these animals grew in the sea region where an enormous number of various microbes already present.

Therefore, microbes are transferred into the body of those animals through food-chain and then learn to live within it. Some of them protect the body and served like healthy microbes in our intestines in present time. While other group likes today's Antibiotic-resistance microbes which will stay and cause disease in the host body.

Thereafter 100-million-year when animals evolutes and crawled onto land they took their microbes with them. According to a study paper published on Online journal Cell, where researchers are studied all species of Enterococci. In fact, they also studied the recent antibiotic-resistance microbes found in hospitals. Therefore the study revealed that most of the Enterococci normally lived in the intestines of most land animals.

Moreover, this study also informed that new species of antibiotic-resistance microbes (Enterococci) appeared whenever new types of animals appeared during evolution. However, on land, intestinal microbes are excreted as feces, where they often dry out and most die over time.

Michael S. Gilmore, a senior scientist at Mass. Eye and Ear said that they figured out what genes were gained by Enterococci hundreds of millions of years ago. At the same time, this Antibiotic-resistance microbe became resistant to drying out, and to disinfectants and antibiotics that attack their cell walls. Therefore, this research is looking for new design of antibiotics and disinfectants that specifically eliminate Enterococci.
