Antibiotic

SAN FRANCISCO — Cannabidiol, or CBD, showed surprising effectiveness against gram-positive bacteria in vitro, including some that were resistant to vancomycin and daptomycin, according to research presented at ASM Microbe.

SAN FRANCISCO — Epidemiologic data and whole genome sequencing revealed a more than 3-year-long transmission of a single bacterial strain with antibiotic-resistant genes in a northern California hospital, according to data presented at ASM Microbe.

SAN FRANCISCO — A novel research program allows students to contribute to the ongoing search for new antibiotics through studying soil samples and conducting hands-on research.

SAN FRANCISCO — Ocean water exposure changes the human skin microbiome and could increase the likelihood of infection after swimming, according to findings presented at ASM Microbe.

SAN FRANCISCO — A genetic analysis of Bacillus strains found in probiotic products that researchers purchased at a supermarket showed that some are resistant to antibiotics, according to data presented at ASM Microbe.

A study published in Pediatrics revealed that children with acute respiratory infections who are treated through direct-to-consumer telemedicine visits are significantly more likely to receive antibiotics. These children, according to the researchers, are also less likely to receive guideline-based antimicrobial treatment.

Although rates of bacterial meningitis are low among neonates and infants, researchers estimated that febrile children in the first month of life are at nearly twice the risk for having bacterial meningitis compared with febrile children aged older than 1 month, according to a meta-analysis published in JAMA Network Open.

The rate of early-onset disease caused by group B Streptococcus, or GBS, has decreased among infants in the United States between 2006 and 2015, according to research published in JAMA Pediatrics. Researchers said late-onset disease caused by GBS is now more common in this population, which means efforts to prevent the disease should shift toward vaccine development rather than intrapartum antibiotic prophylaxis.

Researchers have developed an antibiogram that uses hospital data as well as patient-specific data to predict the likelihood that a treatment will be successful.

Daily use of the probiotic Lactobacillus rhamnosus HN001 reduced the odds of Staphylococcus aureus carriage in stool samples of VA patients with initial extra-gastrointestinal colonization but did not have the same effect in samples from other sites on the body, researchers said.
