When CDC is working on an outbreak of foodborne illness, it’s our goal to pinpoint the source as quickly and precisely as possible so we can prevent any further threat to public health. For several years now, the PulseNet Methods Development and Reference Unit (PMDRU) has been developing and validating new methods to complement pulsed-field gel electrophoresis (PFGE), which is currently the standard typing method used in outbreak detection. The method that we have found most helpful in detecting subtle differences between closely related bacterial strains is a technique known as multiple-locus variable-number tandem repeat analysis (MLVA).

The possibility that E. coli O157:H7 was a contaminant in cookie dough surprised even the most experienced microbiologists here in CDC’s Enteric Diseases Laboratory Branch. E. coli O157 is a common culprit of a severe diarrheal illness, usually caused by eating contaminated and undercooked ground beef or drinking unpasteurized apple juice. It shouldn’t have even been on the “Who’s Who” list of the top bacterial contaminants.

“Wildlife Health from Land to Sea: Impacts of a Changing World.” That was the theme of the 58th annual meeting of the Wildlife Disease Association, held earlier this month. I had the pleasure of attending this conference along with several colleagues from the National Center for Zoonotic, Vector-borne, and Enteric Diseases (NCZVED).

The Public Health Matters blog welcomes requests from its readers. Recently, a reader asked us to address the issue of Hepatitis B in Kuwait. Dr. Frank Mahoney, a CDC medical epidemiologist who has worked extensively in the Middle East, wrote this response:

Q fever is a disease caused by the bacterium Coxiella burnetii, which can be transmitted to humans from animals such as sheep, goats, and cattle. C. burnetii is considered a possible bioterrorism agent because it is quite hardy in the environment, infects people who breathe aerosols containing the organism, and has a very low infectious dose (one organism can cause disease in a susceptible person).

Marburg hemorrhagic fever is one of the world’s deadliest diseases. While not always fatal, infection with the Marburg virus generally causes serious illness. There is no vaccine or drug therapy available for those who become infected and we know that as many of 90 percent of those infected during outbreaks have died.
