Description:
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.

This 2005 photograph of the Centers for Disease Control and Prevention′s Dr. Terrence Tumpey, one of the organization′s staff microbiologists, shows him examining reconstructed 1918 Pandemic Influenza Virus inside a specimen vial. Dr. Tumpey, here seen in a Biosafety Level 3-enhanced laboratory setting, works beneath a flow hood, which pulls air from outside the hood into the hood′s confines, and is then filtered of any pathogens before being re-circulated inside the self contained laboratory atmosphere.

Description:
This image depicts two Centers for Disease Control and Prevention laboratorians, Luanne Elliot and Dave Auperin, as they work under a flow hood inside one of the CDC′s BSL-4 (Bio Safety Lab) laboratories. 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.

Description:
Jason Tully, a CDC laboratorian, is shown here using the pH meter in order to prepare a buffer solution in the Personal Care Products Laboratory (PCPL) located in a CDC lab on the organization′s Chamblee, Georgia campus. The Personal Care Products Laboratory (PCPL) is part of the Organic Analytical Toxicology Branch (OATB) in the Division of Laboratory Sciences (DLS) of the Centers for Disease Control and Prevention (CDC). The Organic Analytical Toxicology Branch conducts research and develops methods for analyzing selected synthetic and naturally occurring organic chemicals and their metabolites, or reaction products in blood or urine.
