Description:
This colorized scanning electron micrograph (SEM) depicts a number of Escherichia coli bacteria of the strain O157:H7. This strain of E. coli is an emerging cause of foodborne illness. An estimated 73,000 cases of infection, and 61 deaths occur in the United States each year. Infection often leads to bloody diarrhea, and occasionally to kidney failure. Most illness has been associated with eating undercooked, contaminated ground beef. Person-to-person contact in families and child care centers is also an important mode of transmission. Infection can also occur after drinking raw milk, and after swimming in, or drinking sewage-contaminated water.

Description:
This colorized scanning electron micrograph (SEM) depicted some of the ultrastructural details seen in the cell wall configuration of a number of Gram-positive Mycobacterium tuberculosis bacteria. TB bacteria become active, and begin to multiply, if the immune system can't stop them from growing. The bacteria attack the body and destroy tissue. If in the lungs, the bacteria can actually create a hole in the lung tissue. Some people develop active TB disease soon after becoming infected, before their immune system can fight off the bacteria. Other people may get sick later, when their immune system becomes weak for another reason.

Depicted in this 2007 photograph is CDC microbiologist Dr. Davis Lupo, shown using a luminometer to measure HIV infection of human cells in vitro, while Lee Lam observes. By employing various chemical reactions to the laboratory cell sample, the release of energy, in the form of emitted light, or bioluminescence, is then measured by this luminometer in quantitative units known as RLUs, or “relative light units.” Dr. Lupo and Ms. Lam are National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) staff members, who work inside the center’s Laboratory Branch (LB).

Description:
In this photo, Dr. Taronna Maines, a microbiologist in the Influenza Branch at the Centers for Disease Control and Prevention, is conducting an experiment inside a biological safety cabinet (BSC) within the Biosafety Level 3-enhanced laboratory. The airflow within the BSC helps prevent any airborne virus from escaping the confines of the cabinet. Dr. Maines was inoculating 10-day old emryonated hen′s eggs with a specimen containing an H5N1 avian influenza virus. This experiment was part of a study to investigate the pathogenicity and transmissibility of newly emerging H5N1 viruses. Identification of genetic markers affecting the ability of H5N1 viruses to transmit efficiently will help in the early identification of emerging H5N1 viruses with pandemic potential. Information gained from this study is important for pandemic preparedness.

CDC scientists working in the biosafety labs must wear protective clothing and head gear, and are supplied air via overhead lines that plug into the suit. The flow hood pulls air into the experimental area by creating a negative pressure, thereby, preventing pathogens from getting out into the general laboratory environment.
