Mar 9, 2017 · Over 6,500 waterfowl—mostly ducks—have died in Canyon County, Idaho, stricken by avian cholera. The outbreak started in February, and before it's over, it may not only be Idaho's largest outbreak, but one of the largest in the country.

Jun 21, 2017 · The new test, the TZA test, detects a gene turned on by replicating HIV. This assay uses TZM-bl cells — laboratory test cells — that have the same HIV receptor on them as on CD4 cells, and also have an integrated copy of the ß-galactosidase gene. When the researcher mixes blood containing HIV with the TZM-bl cells, any replication ...
Jul 25, 2017 · New research explores how the bacteria on the penis can leave men more susceptible to infection with HIV. Since 1981, the HIV/AIDS pandemic has infected more than 70 million people, killing almost 40 million.
May 13, 2017 · Have you ever had a burning sensation when you urinate? Low fever, back pain, and maybe cloudy urine? Male or female, it could have been a urinary tract infection. If it lasted long enough, the chances are good you went to the doctor for help.

Jan 13, 2017 · By genetically-modifying these same parasites, researchers in Seattle recently created a vaccine that appears to be safe and effective in generating an immune response to malaria in a small study of human volunteers. The work is part of a global effort to eliminate the suffering caused by malaria through improved testing, treatment, vector ...
