Resistant Bacteria are a Global problem. Now Researchers May Have Found the Solution!

More and more staphylococci are becoming resistant to antibiotics.

Staphylococcus aureus. You may have had it in connection with a wound infection. In most cases, it will pass without treatment, while severe cases may require antibiotics, which kills the bacteria. This is the case for the majority of the population. In fact, many of us – though we feel perfectly fine – carry staphylococci in the nose, a good, moist environment in which the bacteria thrive.

However, more and more staphylococci are becoming resistant to antibiotics (also known as multi resistant staphylococcus aureus or MRSA), and these infections can be difficult to treat.

Antibiotics resistance is an increasing problem, especially on a global scale. And when you have this relatively simple infection which suddenly cannot be treated with antibiotics, the situation can turn serious, sometimes life-threatening.

Summary

Therefore, all over the world, a lot of resources are being invested in fighting antibiotics resistance in staphylococcus aureus infections, and a new study among skin lymphoma patients has produced positive results. A new substance called endolysins has proven capable of killing both resistant and non-resistant staphylococcus aureus – without the need for antibiotics. But we will get back to that.

The discovery is good news to patients with a weak immune system to whom a staphylococcus aureus infection can be serious and, at worst, fatal. But it also adds to the knowledge we have of other forms of treatment.

Summary

To people who are severely ill with e.g. skin lymphoma, staphylococci can be a huge, sometimes insoluble problem, as many are infected with a type of staphylococcus aureus that is resistant to antibiotics, says Niels Ødum and adds: That is why we are careful not to give antibiotics to everyone, because we do not want to have to deal with more resistant bacteria. Therefore, it is important that we find new ways of treating - and not the least to prevent - these infections.

Summary

New substance may be the answer

In some patients, staphylococcus aureus will cause the cancer to worsen. And even though antibiotics appear to work in some cases, it is not without its problems.

“We can tell that giving high doses of antibiotics to patients with serious infections causes their health, skin and cancer symptoms to improve. But once we stop giving them antibiotics, the symptoms and staphylococci quickly return. Patients experience many adverse effects, and some risk getting resistant bacteria,” says Niels Ødum.

Therefore, treating staphylococcus aureus can be tricky. At worst, cancer patients may die of an infection which doctors are unable to treat.

And this is where endolysins enter the scene, as this new substance may be part of the solution to antibiotics resistance like MRSA.

“This particular endolysin is a brand new, artificially produced enzyme that has been improved several times and designed as a new drug,” explains Postdoc Emil Pallesen, who is first author of the study. He adds:

“The great thing about this enzyme is that it has been designed to penetrate the wall of staphylococcus aureus. This enables it to target and kill the harmful staphylococcus and leave harmless skin bacteria unharmed.”

“We have been testing the substance on skin samples from patients, and it does appear to kill staphylococcus aureus from patients. Endolysins do not care whether the bacterium is resistant to antibiotics or not, because it does not work in the same way as antibiotics,” says Niels Ødum and adds:

“The really good news is that our lab tests have showed that endolysins do not just eradicate staphylococcus aureus; they also inhibit their ability to promote cancer growth.” (NS/Newswise)
