Drug-Resistant Salmonella (WHO Fact Sheet No. 139)
This official WHO fact sheet provides basic information on Salmonellosis, one of the most common and widely distributed foodborne diseases. It constitutes a major public health burden and represents a significant cost in many countries. Millions of human cases are reported worldwide every year and the disease results in thousands of deaths. Salmonellosis is caused by the bacteria Salmonella. Today, there are over 2500 known types, or serotypes, of Salmonella. Recent studies provide increasing evidence of adverse human health consequences due to the occurrence of resistant microorganisms. These consequences can be divided into two categories: (1) infections that would otherwise not have occurred; and (2) increased frequency of treatment failures and increased severity of infections.   (24/Oct/2006)
