Meningococcal Group B Vaccine Associated With Reduced Gonorrhea Incidence
A study conducted at two universities in Oregon suggests meningococcal group B vaccine (MBV) may offer protection against gonorrhea infection, researchers reported today in JAMA Network Open. In the study, researchers with the Oregon Public Health Division analyzed gonorrhea incidence among more than 30,000 students ages 18 to 29 at the University of Oregon and Oregon State University who received one or more doses of MBV following group B meningococcal outbreaks on the two campuses in 2015 and 2016.

Report Describes MDR-TB Outbreak In Kansas, Neighboring State
Investigators say a rare outbreak of multidrug-resistant tuberculosis (MDR-TB) in a social network in Kansas provides a "cautionary tale" for areas with low TB incidence. The outbreak, described today in Morbidity and Mortality Weekly Report, involved 13 people in Kansas and one in a neighboring state and was initially identified in a hospitalized infant in Kansas in November 2021. Resistance to the four drugs that constitute first-line TB therapy was confirmed by DNA sequencing and drug-susceptibility tests. Investigation by public health officials identified four additional members in the infant's household with MDR-TB. (Dall, 8/31)

Study: Ultraviolet Light Has No Measurable Impact On Healthcare-Associated Superbug Infections
A systematic review and meta-analysis found that room disinfection with ultraviolet-C (UV-C) devices had little impact on the incidence of healthcare-associated multidrug-resistant organism (MDRO) infections, researchers reported today in Epidemiology & Infection. The study, conducted by Chinese researchers, analyzed nine previously studies that examined the impact of UV-C devices on the incidence of Clostridioides difficile, vancomycin-resistant Enterococci (VRE), methicillin-resistant Staphylococcus aureus, and gram-negative rod-shaped bacteria.
