Gram Positive Bacteria Pins and Buttons

Streptococcus pyogenes. Coloured transmission electron micrograph (TEM) of the bacteria Streptococcus pyogenes, forming an S-shaped chain. S.pyogenes is a spherical, Gram-positive bacteria that typically forms chains. Healthy humans may carry this bacterium in their throat or nose. Pathogenic strains of S.pyogenes cause infections of the skin (including impetigo); uterus following childbirth (puerperal sepsis); bloodstream (septi- caemia); and scarlet fever. S.pyogenes accounts for much of the high incidence of sore throats and tonsillitis in young children. The use of penicillin drugs are effective as a treatment. Magnification: x7,000 at 6x4.5cm size.

Microbiology design of gram positive cocci and gram negative rods for all you microbiologists.

Oral Streptococcus bacteria. Coloured scanning electron micrograph (SEM) of chains of Streptococcus sp. bacteria from the mouth. Streptococcus bacteria are an example of cocci (round bacteria) that form chains. There are over 50 species of Streptococcus bacteria, some of which cause disease in humans.

Bacteria - Be Gram Postive

Cute little gram positive bacteria

This colorful and accurately researched diagram shows the internal structure of both gram negative, and gram positive bacteria. Even the different flagellar mechanisms are portrayed! Great for migrobiologists and microbiology students!

MRSA ingestion by white blood cell. Coloured scanning electron micrograph (SEM) of methicillin-resistant Staphylococcus aureus (MRSA) bacteria (round) being ingested by a white blood cell. MRSA is a gram-positive, round (coccus) bacterium that is resistant to many commonly prescribed antibiotics. It is carried by around a third of the population without causing any symptoms. However, in vulnerable people, such as those that have recently had surgery, it can cause severe illness due to its high resistance to antibiotics. It can result in wound infections, pneumonia and blood poisoning.

Staphylococcus bacteria. Colour transmission electron micrograph of sectioned Staphylococcus aureus bacteria. They are Gram-positive coccal (spherical) bacteria. At centre a bacterium in cross section is seen with its thick cell wall (green). Above and below this bacterium are obliquely sectioned bacteria showing the irregular surface of the bacterial cell walls. Staphylococcus aureus commonly occurs on healthy human skin and mucous membranes, such as the lining of the mouth. It may, however, become pathogenic. It can be responsible for skin boils, infected hair follicles and internal abscesses. Magnification: x58,333 at 6x7cm size. Magnification: x200,000 at 10x8 inch size.
