Accurate diagnosis of bacterial superinfection pneumonia could help avoid antibiotic overuse

Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Contamination of urban surface water by human waste drives 'superbug' spread

Contamination of urban lakes, rivers and surface water by human waste is creating pools of 'superbugs' in Low- and Middle-Income Countries (LMIC) - but improving access to clean water, sanitation and sewerage infrastructure could help to protect people's health, a new study reveals.

Pre-trained viruses are more effective in countering antibiotic resistance

The risk of antibiotic resistance increases as bacteria continue to evade even the most powerful contemporary medicinal treatments. Antibiotic-resistant microorganisms threaten to take more than 10 million lives by 2050, as present-day treatments prove ineffective.

International travelers may pick up AMR genes from different destinations

According to a research work published in the Genome Medicine journal, travelers abroad may contract bacteria and other vectors with genes that confer antibiotic resistance, which linger in the travelers’ gut when they return home.

Three plausible solutions mitigates zoonotic risk associated with intensive animal agriculture

As early as the Neolithic period (circa 3900 BC), the domestication of animals likely led to the development of diseases including measles and smallpox. Since then, zoonotic disease has led to other major transnational outbreaks including HIV, Ebola, SARS, MERS, and H1N1 swine flu, among others.

Researchers prove that drugs designed for bacteria have the potential to act on human cells

Antibiotics used to treat common bacterial infections may potentially be used to treat human illnesses such as cancer, at least theoretically.

Research uncovers how antibiotics target bacterial RNA Polymerase to inhibit gene transcription

The emergence and spread of new forms of resistance remains a concern that urgently demand new antibiotics. Transcription is a vital process in bacterial cell, where genetic information in DNA is transcribed to RNA for the translation of proteins that perform cellular function.
