Group A streptococcal bacterial infections can range from a mild skin infection or a sore throat to severe, life-threatening conditions. Most people are familiar with strep throat, which along with minor skin infections, is the most common form of the disease. Health experts estimate that more than 10 million mild infections (throat and skin) occur every year. NIHs National Institute of Allergy and Infectious Diseases supports research to develop a group A streptococcus vaccine, and several candidate vaccines are in various phases of development.

This scanning electron micrograph (SEM) depicted a number of red blood cells found enmeshed in a fibrinous matrix on the luminal surface of an indwelling vascular catheter; Magnified 7766x. In this instance, the indwelling catheter was a tube that was left in place creating a patent portal directly into a blood vessel. The erythrocyte in the center had undergone the process of crenation, whereupon, it developed a number of cell wall projections, thereby, transforming it into what is termed an

This digitally-colorized scanning electron micrograph (SEM) revealed some of the ultrastructural morphology displayed on the head region of a bedbug, Cimex lectularius. Of interest is one of the insect's compound eyes. The compound eye is given this name due to the fact that the single large eye is really made up of many repeating units known as ommatidia. Each ommatidium is composed of separate units made up of a photoreceptor cell, support cell, and pigment cells. Though each of these visual mechanisms functions as a separate organ, together they provide the organism with a compound picture of its environment. Due to what is referred to as the flicker effect, the compound eye is made very sensitive to movement, with each ommatidium turning on and off, as objects pass across its field of view. The bilateral anatomical placement of the insect's eyes provides the organism with a very wide range of visual sensitivity.

Under a high magnification of 10,000x, this scanning electron micrograph (SEM) shows a strain of Staphylococcus aureus bacteria taken from a vancomycin intermediate resistant culture (VISA). Under SEM, one can not tell the difference between bacteria that are susceptible, or multidrug resistant, but with transmission electron microscopy (TEM), at least with VISA isolates one can see a thickening in the cell wall that may attribute to their reduced susceptibility to vancomycin. VISA and VRSA are specific types of antimicrobial-resistant staph bacteria. While most staph bacteria are susceptible to the antimicrobial agent vancomycin some have developed resistance. VISA and VRSA cannot be successfully treated with vancomycin because these organisms are no longer susceptibile to vancomycin. However, to date, all VISA and VRSA isolates have been susceptible to other Food and Drug Administration (FDA) approved drugs.
