Tetracycline is an antibiotic drug used to treat infection.
Farmers in parts of Asia are spraying antibiotics deemed "critical" for human medicine on rice crops, raising fears they may be fuelling antibiotic resistance, say researchers.
The latest generation of tetracyclines - a class of powerful, first-line antibiotics - was designed to thwart the two most common ways bacteria resist such drugs.
Antibiotics save lives -- but using them also helps antibiotic-resistant strains evolve and spread. Each year, antibiotic-resistant bacteria infect some 2.8 million people in the United States, killing more than 35,000, according to the Centers for Disease Control and Prevention.
A paper published in the Journal of Biomedical Optics (JBO), "Imaging hydroxyapatite in sub-retinal pigment epithelial deposits by fluorescence lifetime imaging microscopy with tetracycline staining," demonstrates a potential new diagnostic option for catching a degenerative eye disease in its earliest stages.
Microorganisms that infect animals, such as dogs, have the potential to jump to humans and cause illness. Zoonosis is a disease that can spread from animals to humans. These diseases pose health risks, mainly that some types can become life-threatening. Now, a study warns that raw-type dog food contains high levels of multidrug-resistant bacteria, which has the potential of transmitting the bacteria between dogs and humans.
High levels of antibiotic residues, other medicines and chemicals present in Bangladesh's ponds, canals, lakes, rivers and other surface waters are contributing to a spike in antibiotic resistance in the country, says a new study.
The use of human urine as fertilizer is an important step towards sustainable agriculture because the starting reagent is free, plentiful and useless in most other contexts. It has been used as such for centuries, but with the current focus on environmental sustainability, the possibility of creating a nutrient cycle is under scrutiny. In other words, sourcing fertilizer from urine can be a green way to supply plants with the nutrients they need.
Central London's freshwater sources contain high levels of antibiotic resistant genes, with the River Thames having the highest amount, according to research by UCL.
UNC School of Medicine scientists created a powerful new "directed evolution" technique for the rapid development of scientific tools and new treatments for many diseases.
A scientific team from Case Western Reserve University School of Medicine and Cleveland Clinic has developed a new way to identify second-line antibiotics that may be effective in killing germs already resistant to a first-line antibiotic - potentially helping overcome antibiotic resistance.
Face masks appear to provide important protection against drug-resistant Staphylococcus aureus bacteria for hog farm workers and for household members to whom they might otherwise transmit the bacteria, according to a study led by scientists at Johns Hopkins Bloomberg School of Public Health.
The bite from a brown recluse spider (Loxosceles) can cause skin necrosis, renal failure, and even death. A new ointment is being tested in Brazil, however. Its effects have already been proven in tests conducted in cell cultures and animal models.
Salad is popular with people who want to maintain a balanced and healthy diet. Salad varieties are often offered for sale ready-cut and film-packaged. It is known that these types of fresh produce may be contaminated with bacteria that are relevant from the point of view of hygiene.
Brazil's Ministry of Health received reports of 11,524 outbreaks of foodborne diseases between 2000 and 2015, with 219,909 individuals falling sick and 167 dying from the diseases in question.
We know that antibiotics treat bacterial infections. We also know why they work. Tetracycline antibiotics, for example, stop bacteria from making protein. Like a boot on a wheel, the drugs bind to the bacterial cell's ribosome--where protein is made--and prevent it from working. Without protein, the bacteria weaken and die.
People are often notified about poor air quality by weather apps, and this happens frequently in urban areas, where levels of outdoor pollution containing particulates and soot are high.
In a finding that suggests the potential for practice change that would reduce the use of antibiotics in dermatology, researchers in the Perelman School of Medicine at the University of Pennsylvania have found the diuretic drug spironolactone may be just as effective as antibiotics for the treatment of women's acne.
Each year, farmers in the U.S. purchase tens of millions of pounds of antibiotics that are approved for use in cows, pigs, fowl and other livestock.
Bacteria from humans and animals continue to show resistance to antimicrobials, according to a new report published today by the European Food Safety Authority and the European Centre for Disease Prevention and Control.
The genes that are able to equip bacteria with resistance to clinically used antibiotics have been found in many different natural environments. Nevertheless, a functional overview of the resistance genes found in common human bacterial pathogens has been missing so far.
