And even though the resistant bacteria weren't found in older pigs destined for slaughter, "there is a real risk that [carbapenem-resistant bacteria] may disseminate in food animal populations and eventually contaminate fresh retail meat products. (cosmosmagazine.com)
They are also highly effective against carbapenem-resistant enterobacteria, where most other antibiotics fail. (phys.org)
To determine the effect of antibiotics, the team tested them on samples of human feces in the lab, alongside experiments in mice and lab tests of carbapenem-resistant Enterobacteriaceae (CRE). (phys.org)
First author Alexander Yip, from the Centre for Bacterial Resistance Biology in the Department of Life Sciences at Imperial, said, "Understanding how antibiotics cause carbapenem-resistant Enterobacteriaceae to grow in the intestine means that we can develop new treatments to restrict their growth in the intestine, which will lead to a reduction in these antibiotic-resistant infections. (phys.org)

The role of companion animals as potential reservoirs of antimicrobial-resistant bacteria is a growing concern worldwide. (eurekalert.org)

Tetracyclines are a type of broad-spectrum antibiotics. (healthline.com)
On the other hand, a report published by the New Delhi-based Center for Disease Dynamics, Economics & Policy (CDDEP) in November 2017 says that over 70 per cent of acinetobacterbaumannii bacteria and 50 per cent of pseudomonas aeruginosa bacteria are resistant to broad-spectrum antibiotics like third generation cephalosporin. (org.in)
Broad-spectrum antibiotics are those that are effective against a wide range of disease-causing bacteria, in contrast to narrow-spectrum antibiotics, which are effective against specific families of bacteria. (org.in)
Carbapenems are broad-spectrum antibiotics that are strong but often used as a last resort, due to their negative impacts on beneficial bacteria . (phys.org)

That can include unintentionally killing off the good bacteria in our gut. (healthline.com)
Most importantly, they found that two classes of antibiotics - tetracyclines and macrolides - create "collateral damage" by wiping out good bacteria in the gut, leaving it open to gastrointestinal ailments and recurring infections from a type of bacteria known as Clostridioides difficile ( C. diff ), which can cause severe diarrhea, nausea, fever, stomach pain, and even death.

Gut health and the stability of the human body's microbiome is essential to good health, so using powerful antibiotics is a balancing act of sorts. (bgr.com)
Typically, it will take the body time to balance the microbiome to healthy, diverse bacteria levels. (onteenstoday.com)
This is according to new research led by Imperial College London scientists, which could lead to better patient risk assessment and "microbiome therapeutics "treatments to help combat antibiotic-resistant bacteria. (phys.org)
New findings hint at promising strategies to prevent infections with drug-resistant bacteria by protecting or restoring the microbiome. (elifesciences.org)
Protecting the microbiome may be essential to curbing the spread of harmful, drug-resistant bacteria, suggests a study published today in eLife. (elifesciences.org)
Trillions of bacteria inhabit the human body and there is growing evidence that this microbiome is essential to human health. (elifesciences.org)
The findings add to this evidence by showing that a healthy microbiome not only plays a crucial role in preventing or fighting off infections, but also helps reduce the spread of drug-resistant strains of harmful bacteria. (elifesciences.org)
Antibiotics are a key tool in treating infections with harmful bacteria, but they may also harm the microbiome. (elifesciences.org)
Without a healthy microbiome, there is less competition for resources which may allow harmful bacteria to multiply. (elifesciences.org)
We used mathematical modelling to see how the effects of antibiotics on the microbiome might drive the spread of antibiotic-resistant bacteria in healthcare settings. (elifesciences.org)
However, interventions that protect the microbiome, such as using fewer antibiotics or helping to restore the microbiome in patients after antibiotic treatment, may help limit the spread of drug-resistant bacteria. (elifesciences.org)
Our study reveals how important it is to consider the protective effects of a healthy microbiome when designing strategies to reduce the dissemination of drug-resistant strains of bacteria," concludes co-senior author Lulla Opatowski, Professor in Mathematical Epidemiology at UVSQ, and senior researcher in the Epidemiology and Modeling of Antibiotic Evasion group at the Institut Pasteur. (elifesciences.org)
Together, both antibiotic stewardship and interventions to support a healthy microbiome could be effective in mitigating the burden of these infections. (elifesciences.org)

Previous microbiological studies found a range of bacteria associated with HS lesions, but these were usually considered contaminants of the primary lesions. (medscape.com)
Because the new drug is capable of attacking a wide range of bacteria, it's considered broad-spectrum, which is both good and bad. (bgr.com)

Furthermore, many spiders have been shown to have venom with antibacterial activity and it is often debated as to whether the venom would neutralize bacteria at the bite site, but this also demonstrates, at least for the Noble False Widow, that the venom does not inhibit bacteria. (scitechdaily.com)
The insights may lead to the design of new antibiotic therapies to inhibit the drug-resistance activities of RNA methyltransferase enzymes. (emory.edu)
In 2015, for example, Dunham's lab obtained precise pictures through X-ray crystallography of how an enzyme known as HigB rips up RNA to inhibit growth of the bacteria. (emory.edu)
Tetracyclines inhibit protein synthesis and, therefore, bacterial growth by binding with 30S and possibly 50S ribosomal subunits of susceptible bacteria. (medscape.com)

There is no way around the fact that antibiotics kill both harmful and beneficial bacteria in the gut," Bell told Healthline. (healthline.com)
Because the antibiotic is only active inside infected cells, it won't wipe out the other bacteria - beneficial bacteria - with drugs distributed more broadly in the body. (theverge.com)
Broad-spectrum antimicrobial agents are great at killing off many different kinds of harmful bacteria, but the flip side is that they can also inadvertently wipe out beneficial bacteria in parts of the body like the gut. (bgr.com)

Repeated and improper use of antibiotics contributes to this process. (onteenstoday.com)

By restraining the growth of the bacteria that makes it, HigB establishes a dormant "persister cell" state that makes the bacteria tolerant to antibiotics. (emory.edu)
