A new study on Clostridioides difficile infections finds that choosing an alternative antibiotic for high-risk patients with pneumonia can reduce infection risk.

C. diff infections can be deadly, and they are often acquired by hospitalized patients taking broad-spectrum antibiotics.

More than 450,000 C. diff infections are reported in the United States eac...

Many antibiotics long used to treat common childhood infections are no longer effective because of antibiotic resistance.

The authors of a new study say global guidelines on antibiotic use need to be updated to reflect this, and they called for an increased focus on developing new antibiotics for in...

Millions of people undergo joint replacement surgery every year. To prevent infection, doctors often give them a second antibiotic -- but new research suggests this can backfire.

Adding a second antibiotic at the time of hip and knee replacement surgery may actually increase infections, researchers in Australia found.

"Given the number of joint replacements performed in Austral...

New research shows that an antibiotic effective for bacterial pneumonia also appears to fight treatment-resistant staph infections.

The drug is ceftobiprole. It appeared successful in fighting methicillin-resistant staph infections, sometimes called MRSA. It showed similar benefit when tested against the antibiotic daptomycin to treat complicated Staphylococcus aureus infections....

New research on a leading cause of foodborne illness has linked a large share of Michigan infections to antibiotic-resistant bacteria strains.

More than 100 strains of Campylobacter jejuni circulating in Michigan are resistant to at least one antibiotic, according to researchers from Michigan State University (MSU) and the Michigan Department of Health and Human Services. More th...

Most people with appendicitis who are given antibiotics -- instead of having their appendix removed -- fare well over the long haul, new research indicates.

Testing children with a suspected sinus infection for three common bacteria might cut unnecessary antibiotic prescribing, a new study suggests.

Only half of kids with sinusitis -- inflammation or swelling of the sinuses -- show any improvement with antibiotics, which target bacterial infections, not viral infections, the researchers note.

The United States already has a big problem with syphilis, with cases rising for more than 20 years. Cases increased nearly 75% between 2017 and 2021 alone, bringing the number to more than 176,000 in 202...

Bacteria found in hospital patients in Ukraine is showing extreme antibiotic resistance, making it harder to treat the wounded and ill in this war-torn country, new research warns.

"I am quite thick-skinned and have witnessed numerous situations involving patients and bacteria," said study author and bacteriologist
