Scientists identify immunological profiles of people who make powerful HIV antibodies
People living with HIV who naturally produce broadly neutralizing antibodies (bNAbs) that may help suppress the virus have different immunological profiles than people who do not, researchers report. While bNAbs cannot completely clear HIV infections in people who already acquired the virus, scientists believe a successful preventive HIV vaccine must induce bNAbs. Defining how to safely replicate these attributes in HIV-uninfected vaccine recipients may lead to better designed experimental vaccines to protect against HIV.

Researchers find molecular switch that triggers bacterial pathogenicity
The supercoiling of bacterial chromosomes around histone-like proteins can trigger the expression of genes that make the microbe invasive, new research shows. The discovery could provide a new target for the development of drugs to prevent or treat bacterial infection, say scientists.

Vaccination: Zika infection is caused by one virus serotype
Vaccination against a single strain of Zika virus should be sufficient to protect against genetically diverse strains of the virus, according to a new study.

Green monkeys acquired Staphylococcus aureus from humans
Many deadly diseases that afflict humans were originally acquired through contact with animals. New research suggests that pathogens can also jump the species barrier to move from humans to animals. The study shows that green monkeys in The Gambia acquired Staphylococcus aureus from humans.

Florida investigation links four recent Zika cases to local mosquito-borne virus transmission
The Centers for Disease Control and Prevention (CDC) has been informed by the State of Florida that Zika virus infections in four people were likely caused by bites of local Aedes aegypti mosquitoes. The cases are likely the first known occurrence of local mosquito-borne Zika virus transmission in the continental United States. CDC is closely coordinating with Florida officials who are leading the ongoing investigations, and at the state's request, sent a CDC medical epidemiologist to provide additional assistance.

Teens who smoke daily are more likely to report health complaints
As fewer teens overall take up smoking, those who do smoke daily are reporting more health complaints than in years past, a new study indicates.

Acute kidney injury identifiable in preterm infants
Early diagnosis of acute kidney injury in preterm infants is possible through urinary protein markers, say investigators. Improving the ability to diagnose AKI, a sudden decline in kidney function, is critical, as approximately 25 percent of preterm infants develop AKI.
