Avian Influenza A H5N1
PHIL ID # 1841
Download High Resolution
Description:
Colorized transmission electron micrograph of Avian influenza A H5N1 viruses (seen in gold) grown in MDCK cells (seen in green).
Avian influenza A viruses do not usually infect humans; however, several instances of human infections and outbreaks have been reported since 1997. When such infections occur, public health authorities monitor these situations closely.
MRSA

Description:
This 2005 colorized scanning electron micrograph (SEM) depicts numerous clumps of methicillin-resistant Staphylococcus aureus (MRSA) bacteria. Methicillin-resistant Staphylococcus aureus infections, e.g., bloodstream, pneumonia, bone infections, occur most frequently among persons in hospitals and healthcare facilities, including nursing homes, and dialysis centers.

E. Coli
PHIL ID # 10068
Download High Resolution
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.
Tuberculosis
PHIL ID # 9997
Download High Resolution
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.
