Escaping the Post-Antibiotic Apocalypse
The term “Post-antibiotic apocalypse” may sound alarmist, but it has been coined for good reason: the decreasing effectiveness of antibiotics against bacterial infections. The global misuse of antibiotics has facilitated the spread of resistance genes, resulting in multidrug resistant pathogens, known as “superbugs”.

			New study identifies chemical receptors in cells to reduce drug resistance The bacterium Pseudomonas aeruginosa is the leading cause of hospital-acquired infections. The pathogen is resistant to many antibiotics so treating those infections, particularly in patients with compromised immune systems, is difficult.

			Discovery of novel mechanism in the gut microbiome has implications for people with IBD Many people associate the word "bacteria" with something dirty and disgusting. Dr. Pere Santamaria disagrees. Called the microbiome, the bacteria in our bodies have all kinds of positive effects on our health, Santamaria says. "The bacteria we have in our gut actually have many beneficial functions. They help in our digestion, prevent infection by pathogens and educate our immune system on what to fight."

	Researchers identify predator bacteria in microbiota of cystic fibrosis patients For the first time, researchers have found the presence of predator bacteria in the microbiota of cystic fibrosis patients. There are researchers from Universidad Politécnica de Madrid among the authors of this finding.

	Lung microbiome plays major role in asthma severity and response to treatment While the microbiome has gained significant attention for its impact on digestive health in recent years, its effect on lung disease has largely remained unstudied.

	Researchers identify mechanisms through which H. pylori bacteria cause gastric cancer Gastric cancer is one of the five most fatal types of cancer. According to the statistics of the World Health Organization, about 750,000 patients die each year after developing the disease. The main cause is thought to be the bacterium Helicobacter pylori (H. pylori).

	Scientists develop novel antimicrobials to tackle multidrug-resistant bacteria Scientists at the University of Surrey in collaboration with research partners at the University of Sheffield and University of Würzburg, Germany, have developed novel antimicrobials, which could be used to treat infections, caused by multidrug-resistant bacteria.
