Microbes living in the rectum could make a difference to the effectiveness of experimental HIV vaccines, according to researchers at the University of California, Davis. The work is published Dec. 11 in the journal mSphere.
Evidence from human and animal studies with other vaccines suggests that Lactobacillus supplements can boost production of antibodies, while treatment with antibiotics can hamper beneficial immune responses, said Smita Iyer, assistant professor at the UC Davis Center for Immunology and Infectious Diseases and School of Veterinary Medicine.
In a 19-year study at the University of California, Davis, scientists dug six feet down in a study plot to compare changes in soil carbon in conventional, cover-cropped, and compost-added plots of corn-tomato and wheat-fallow cropping systems.
Their findings showed that soil health and the importance of carbon is more complex than often realized but, with the right management, the soil is a huge natural resource where carbon can be sequestered.
The implications are that the right applications not only help to slow the rapid rise of carbon in the atmosphere but foster effective sustainable agriculture.
