When a drug prevents bacteria from synthesizing their own folate, an essential compound for their survival, they take it directly from the host. This antibiotic resistance mechanism had not been detected until now because bacteria behave differently in the laboratory than they do in vivo during an infection.
At the Saturday, Oct. 22 session, ‘Basic Science: Correlates of protection, immune response and the host-microbe interaction,’ of the IDWeek 2022 infectious disease conference, moderator Luiz Bermudez, professor at Oregon State University, introduced the latest advances to prevent infections with Treponema pallidum during neurosyphilis (NS), Staphylococcus aureus and osteomyelitis, and Mycobacterium tuberculosis during influenza.
The U.K. is launching a coordinated national program of research into the unprecedented outbreak of monkeypox that has spread across Europe and North America – regions where the disease is not endemic – over the past six months. Taking a lead from the SARS-CoV-2 playbook, there will be work to sequence the viral genome and to study how it is evolving, linking this to changes in the transmission and pathology of the virus.
The Nobel Prize in Physiology or Medicine 2022 was awarded to Svante Pääbo today "for his discoveries concerning the genomes of extinct hominins and human evolution." Pääbo, who is currently the director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and his colleagues overcame extreme technical challenges to sequence the DNA of ancient hominids – because after tens of thousands of years, there is no such thing as aging well for DNA.
Scientists from the University of Queensland have created a new antibiotic that can neutralize various gram-positive bacteria in mice, including major threats such as methicillin-resistant Staphylococcus aureus (MRSA). In a recent study, published in the Sept. 14, 2022, issue of Science Translational Medicine, the new compound outperformed the approved antibiotic vancomycin, and destroyed tough-to-eradicate bacterial biofilms while prompting a low rate of resistance.
From the beginning of the monkeypox outbreak in the U.S. in May, the federal government has bungled the response, according to both Democratic and Republican members of the Senate Health, Education, Labor and Pensions (HELP) Committee.
After nearly four decades as director of the U.S. NIH’s National Institute of Allergy and Infectious Diseases (NIAID), 81-year-old Anthony Fauci will be stepping down in December. He also announced Aug. 22 that he will be handing over the reins as chief of the NIAID Laboratory of Immunoregulation and as chief medical adviser to President Joe Biden.
Rapid point-of-care (POC) diagnostics company Lumos Diagnostics Holdings Pty. Ltd. saw its stock plummet 65% on the news that the U.S. FDA rejected its Febridx 510(k) because the device was not substantially equivalent to the predicate device.
The U.S. FDA has rejected Verrica Pharmaceuticals Inc.’s drug-device combination to treat the viral skin disease molluscum for a third time, losing more ground to a potential rival from Novan Inc., because of continued manufacturing issues. There are no FDA-approved treatments for molluscum contagiosum, which leads to skin-colored or pink lesions and affects around 6 million people in the U.S. annually.
Royal Philips NV expanded its commitment to increasing awareness of cardiovascular implantable electronic device (CEID) infections with a new partnership with the American Heart Association (AHA). The organizations are rolling out a program to educate medical professionals on the proper management of these infections which are commonly treated with antibiotics, an approach that leads to reinfection in the majority of cases.
