Cross-respiration Between Oral Bacteria Leads to Worse Infections

Washington, D.C.—June 28, 2016—Researchers determined that two bacterial species commonly found in the human mouth and in abscesses, cooperate to make the pathogenic bacterium, Aggregatibacter actinomycetemcomitans, more infectious. Key to the cooperation is that the harmless partner provides th... Read More

Researchers Identify New Strategy for Decreasing Neonatal Mortality

Researchers have discovered how the bacteria Group B streptococcus (GBS) avoids detection by the immune system during pregnancy. The findings, reported in the journal mBio, could lead to the development of new drugs and strategies for treating GBS infection, which is a leading cause of neonatal ... Read More

Small RNAs regulate Bacteroides nutrient use

Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More

Anthrax capsule vaccine completely protects monkeys from lethal inhalational anthrax

Vaccination with the anthrax capsule--a naturally occurring component of the bacterium that causes the disease--completely protected monkeys from lethal anthrax infection, according to a study published online this week in the journal VACCINE. These results indicate that anthrax capsule is a hig... Read More

Mount Sinai researchers track HIV in real time as it infects and spreads in living tissue

By watching brightly glowing HIV-infected immune cells move within mice, researchers at the Icahn School of Medicine at Mount Sinai have shown how infected immune cells latch onto an uninfected sister cell to directly transmit newly minted viral particles. These interactions allow HIV to spread ... Read More
