Probiotics Show No Impact in Preventing Gastrointestinal Colonization with Drug-Resistant Organisms
August 27th 2015Probiotics show no benefit for preventing or eliminating gastrointestinal colonization with drug-resistant organisms in patients in the intensive care unit compared to standard care, according to new research published online today in Infection Control & Hospital Epidemiology.
UCSB Researchers Demonstrate How Gram-Negative Bacteria Deliver Toxins to Kill Neighboring Bacteria
August 27th 2015It's bacteria against bacteria, and one of them is going down. Two UC Santa Barbara graduate students have demonstrated how certain microbes exploit proteins in nearby bacteria to deliver toxins and kill them. The mechanisms behind this bacterial warfare, the researchers suggest, could be harnessed to target pathogenic bacteria. Their findings appear in the Proceedings of the National Academy of Sciences.
MMWR Reports on 11 Human Plague Cases
August 26th 2015A report in the CDC's Morbidity and Mortality Weekly Report (MMWR) by Natalie Kwit, DVM, and colleagues, explores the 11 cases of human plague that have been reported in residents of six states since April 1, 2015 (Arizona (two), California (one), Colorado (four), Georgia (one), New Mexico (two), and Oregon (one). The two cases in Georgia and California residents have been linked to exposures at or near Yosemite National Park in the southern Sierra Nevada Mountains of California. Nine of the 11 patients were male; median age was 52 years (range = 14–79 years). Three patients aged 16, 52, and 79 years died.
Hepatitis A-Like Virus Identified in Seals
August 26th 2015Scientists in the Center for Infection and Immunity at Columbia University's Mailman School of Public Health have discovered a new virus in seals that is the closest known relative of the human hepatitis A virus. The finding provides new clues on the emergence of hepatitis A. The research appears in the July/August issue of mBio, the online open-access journal of the American Society for Microbiology.
Dust Can Reveal Profile of Microbial Communities in the Home
August 26th 2015The humble dust collecting in the average American household harbors a teeming menagerie of bacteria and fungi, and as researchers from the University of Colorado Boulder and North Carolina State University have discovered, it may be able to predict not only the geographic region of a given home, but the gender ratio of the occupants and the presence of a pet as well.
Book Details Safety, Security Methods for Laboratory Biorisk Management
August 26th 2015Recent mishaps at laboratories that mishandled potentially dangerous biological substances and the transmission of the Ebola virus in a U.S. hospital are symptoms at bioscience facilities that two Sandia National Laboratories researchers think could be prevented by implementing the practices in a new book on biorisk management.
Pregnancy is a Missed Opportunity for HIV-Infected Women to Gain Control Over Condition
August 25th 2015Pregnancy could be a turning point for HIV-infected women, when they have the opportunity to manage their infection, prevent transmission to their new baby and enter a long-term pattern of maintenance of HIV care after giving birth--but most HIV-infected women aren't getting that chance. That is the major message from a pair of new studies in Philadelphia, one published early online this month in the journal Clinical Infectious Diseases, and the other published in July in PLOS ONE.
Microbiologists Investigate How to Fight Opportunistic Pathogens
August 24th 2015The Department of Microbiology at Kazan Federal University is investigating factors which allow bacteria to persist in human body when exposed to high-strength antibiotics. The team is focused on Proteus, Morganella, Providencia, and Serratia genera, which all are identified as opportunistic microbes and thus are dangerous to individuals with weakened immune system.
