Staphylococcus aureus News and Research

RSS

Staphylococcus aureus is a spherical bacterium (coccus) which on microscopic examination appears in pairs, short chains, or bunched, grape-like clusters. These organisms are Gram-positive. Some strains are capable of producing a highly heat-stable protein toxin that causes illness in humans.

Raw-type dog food contains high levels of multidrug-resistant bacteria

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.

Pets have a low risk of transmitting multi-drug resistant bugs to owners, study finds

Zoonoses are diseases that are transmitted from animals to humans. About 75 percent of emerging infectious diseases are zoonoses, just like the coronavirus disease (COVID-19) that’s caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Domesticated animals such as pets can carry parasites and other pathogens to people. However, a new study suggests that pets are not a significant source of transmission to humans.

Tiger with SARS-CoV-2 infection demostrates reverse zoonosis

Some viruses come from animals and jump to humans to cause disease. In the case of the novel coronavirus, now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it is thought to have come from bats, jumped to an intermediate animal host, and then onto humans. But can the virus leap from humans to other animals?

Cannabidiol helps fight antibiotic-resistant bacteria

Since the discovery of penicillin in 1928 by Sir Alexander Fleming, antibiotics have saved millions of lives from fatal infections world-wide. However, with time bacteria have developed mechanisms to escape the effects of antibiotics - they have become resistant.

Antibiotic blocks the integration of building blocks into the cell wall of pathogens

One of the last arrows in the quiver in the fight against dangerous bacteria is the reserve antibiotic daptomycin.

G-FET based biosensors for selective identification of deadly bacteria strains

Using a single atom-thick sheet of graphene to track the electronic signals inherent in biological structures, a team led by Boston College researchers has developed a platform to selectively identify deadly strains of bacteria, an advance that could lead to more accurate targeting of infections with appropriate antibiotics, the team reported in the journal Biosensors and Bioelectronics.

New bacteria-killing light-activated coating

A new antimicrobial coating that can be activated by light has been reported by researchers in the journal Nature Communications, in March 2020. The coating can be used to prevent transmission from computer and phone screens and keyboards, the inside of catheters, and breathing tubes. All these are significant routes of healthcare-associated infections (HCAIs).

Two common Staph bacteria living on human skin exacerbate Netherton syndrome

Netherton syndrome, a rare skin disease caused by a single genetic mutation, is exacerbated by the presence of two common Staphylococcal bacteria living on human skin, one of which was previously thought to only offer protective properties, report University of California San Diego School of Medicine researchers.

SFU researchers help discover potential new drug to kill superbugs

Researchers in Simon Fraser University's Brinkman Laboratory are collaborating with U.S. researchers to test a new drug that can kill a wide range of superbugs - including some bacteria now resistant to all common antibiotics.

New immunotherapeutic strategy shows promise to fight off infectious biofilms

The same way baking soda breaks down grease and grime, making surfaces easier to clean, researchers at the Lewis Katz School of Medicine at Temple University now show that a new therapeutic molecule can break apart communities of harmful bacteria, opening the way for bacteria-killing antibiotics to more effectively clear out infections.

New immune cell with 'Jekyll and Hyde properties' identified

Scientists at Trinity College Dublin have identified a rare, new cell in the immune system with "Jekyll and Hyde properties". These cells play a key protective role in immunity to infection but - if unregulated - also mediate tissue damage in autoimmune disorders.

Metal complexes could hold the key to next generation of antibiotics

Compounds containing metals could hold the key to the next generation of antibiotics to combat the growing threat of global antibiotic resistance.

Study finds no benefit in using broad-spectrum antibiotics as initial pneumonia treatment

Doctors who use drugs that target antibiotic-resistant bacteria as a first-line defense against pneumonia should probably reconsider this approach, according to a new study of more than 88,000 veterans hospitalized with the disease.

McMaster researchers identify antibacterial compound made by cannabis plants

McMaster University researchers have identified an antibacterial compound made by cannabis plants that may serve as a lead for new drug development.

Researchers uncover hidden antibiotic potential of cannabis compound

Public health agencies worldwide have identified antibiotic resistance of disease-causing bacteria as one of humanity's most critical challenges. However, scientists haven't discovered a new class of antibiotics in more than 30 years.

Inadequate precleaning can jeopardize sterilization of surgical tools

Vaporized hydrogen peroxide failed to completely sterilize surgical tools 76 percent of the time when the tools were soiled with salts or blood and not cleaned prior to sterilization, according to a study published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.
