In the absence of early antibiotic treatment, respiratory anthrax is fatal. The 2001 bioterrorism attacks in the US killed four people, out of 22 infected (10 of them with respiratory anthrax), despite massive antibiotic administration, probably because therapy did not begin until the disease ha...

Stephan Harbarth from the University of Geneva, Switzerland and colleagues argue that the International Health Regulations (IHR) should be applied to the global health threat of antimicrobial resistance. They say that certain events marking the emergence and spread of antimicrobial-resistant bac... Read More
Patients admitted to hospital with inflammatory bowel disease (IBD) face a sixfold greater risk of death if they become infected with Clostridium difficile, a new study has found. The researchers say IBD patients should be screened on admission to protect them from serious illness.
