Drug-Resistant Infections

Drug-Resistant Infections Transmitted by Fecal Transplants

Drug-Resistant Infections; the US Food and Drug Administration (FDA) is alerting healthcare providers and patients that fecal microbiota for transplant (FMT) may transmit multidrug-resistant organisms, leading to serious or life-threatening infections. But in a safety communication issued today, the FDA said two immunocompromised adults who received FMT developed invasive bacterial infections caused by extended-spectrum beta-lactamase (ESBL)–producing Escherichia…

Microbiome

Microbiome Changes Lead To Early Detection Of Colorectal Cancer

Microbiome in the gut has a population of organisms that live within in it, called the gut microbiome; which are link to human health and disease. Recent studies have shown that assessing the genetic changes in fecal samples; but can accurately reflect the status of the gut microbiome, and may be useful for the early…

Roundworms

Roundworms Help Identify New Anti-Aging Compounds

Roundworms; Researchers from Gero, Skolkovo Institute of Science and Technology (Skoltech); Moscow Institute of Physics and Technology (MIPT), and University of Arkansas for Medical Sciences (UAMS); have collaborated to derive a transcriptomic signature of aging, which they confirmed using large transcriptomic databases. They discovered that aging in nematodes is partially programme and can be therapeutically…

Antibiotic Resistance Mechanism

Spying Super-bugs To Study The Antibiotic Resistance Mechanism

Antibiotic Resistance Mechanism; Scientists have discovered yet another way that single-celled organisms have outsmarted us. The tiny bacteria that live inside the guts have an ingenious way of withstanding the onslaught of antibiotics thrown at them, according to a report published Thursday in the journal Science. The two-part system allows bacterial cells to stay alive…

Muscle Atrophy

The Prospect Of New Therapies To Delay Muscle Atrophy

Mitochondrial dysfunction impairs muscle health and causes subsequent muscle wasting. This study explores the role of mitochondrial dysfunction as an intramuscular signal for the extracellular matrix (ECM); based proteolysis and, consequentially, muscle cell dystrophy. The researchers found that inhibition of the mitochondrial electron transport chain causes paralysis; but as well as muscle structural damage in…

Fermented Food and immune system

Fermented Food: Bacteria Signals The Human Immune System

Researchers have discovered that humans and great apes possess a receptor on their cells; but fermented food detects metabolites from bacteria commonly found in fermented foods and triggers movement of immune cells. Claudia Stäubert of the University of Leipzig and colleagues report these findings in a new study published 23rd May in PLOS Genetics. Consuming…

Regulating Gut Bacteria

Anxiety Might Be Alleviated By Regulating Gut Bacteria

People who experience anxiety symptoms might be help taking steps to regulate the microorganisms; in their gut using probiotic and non-probiotic food and supplements; suggests a review of studies published today in the journal General Psychiatry. Anxiety symptoms are common in people with mental diseases and a variety of physical disorders, especially in disorders that…

Gram-Negative Bacteria

Biology Of Antibiotics In Gram-Negative Bacteria

Bacteria have fascinating properties. They adapt excellently to their respective environment, and they existed long before humans. Their toughness has led to the fact that bacteria have successfully spread all over the world for three billion years; even in places where humans could not survive, for example in the hottest springs and in the coldest…

The Fungus

The Fungus Could Help Fight Drug-Resistant Fungal Infections

How do you fight a fungal infection that is becoming increasingly resistant to medicine? By starving it, found a team of University at Buffalo and Temple University researchers. But to treat Candida albicans, a common yeast that can cause illness in those with weakened immune systems; researchers limited the fungus’ access to iron, an element crucial…

Parasitic Infection

A New Drug Reverse Hyperactivity Of Parasitic Infection

When rodents get infected by Toxoplasma gondii, the single-celled brain parasite that causes toxoplasmosis, they become hyperactive risk-takers. In findings published this week in mBio, researchers show for the first time that it’s possible; to reverse that behavioral change. Surprisingly, the study also showed that the restoration of normal behavior resulted from reducing inflammation; and not from…

Vaccinations

Study Reveals Better Way To Help Increase Support For Vaccinations

The re-introduction of measles, mumps and other previously eradicate diseases to the United States is nothing short of a public health crisis. Since Jan. 1, a staggering 880 individual cases of measles have confirm in 24 states the greatest number of cases since 1994. Measles was declare eliminate in the U.S. in 2000. The outbreaks…

Pathogens

Pathogens Use Sophisticated Molecular Machinery To Infect Hosts

Gastric cancer, Q fever, Legionnaires’ disease, whooping cough though the infectious bacteria; that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells; and also to spread genes for antibiotic…
