Under a magnification of 3841X, this scanning electron micrograph SEM) revealed some of the ultrastructural morphologic details exhibited by a number of Gram-positive bacilli, or rod-shaped, Mycobacterium fortuitum bacteria. See PHIL 11032 for a black and white version of this image.M. fortuitum is classified as a rapidly-growing Mycobacterium, due to the fact that it can be grown on laboratory culture medium in less than 7 days. As a human pathogen, this organism has been determined to be the cause of skin infections, including furunculosis, i.e., boils, on the legs of people receiving pedicures in nail salons.Created: 2009

Under a very high magnification of 25000X, this colorized scanning electron micrograph (SEM) revealed the presence of a single Gram-negative Salmonella typhimurium bacterium, which was imaged right at the point where it was undergoing the process of cell division, resulting in the formation of two separate organisms. This dividing bacterium had been isolated from a pure culture. See PHIL 10994 for a black and white version of this image.Created: 2009

Under a very high magnification of 20000X, this colorized scanning electron micrograph (SEM) revealed the presence of a single Gram-negative Salmonella typhimurium bacterium that had been isolated from a pure culture.

They are microscopic living creatures that pass from the feces of people or animals to other people or other animals. There are many different kinds of Salmonella bacteria. Salmonella serotype Typhimurium and Salmonella serotype Enteritidis are the most common in the United States. Salmonella germs have been known to cause illness for over 100 years. They were discovered by an American scientist named Salmon, for whom they are named.Created: 2009

Under a magnification of 2500X, this colorized scanning electron micrograph (SEM) revealed the presence of a large number of Gram-negative Salmonella typhimurium bacteria that had been isolated from a pure culture. See PHIL 10984 for a black and white version of this image.How do people catch Salmonella?What can I do to prevent salmonellosis?- Cook poultry, ground beef, and eggs thoroughly. Do not eat or drink foods containing raw eggs, or raw (unpasteurized) milk.- If you are served undercooked meat, poultry or eggs in a restaurant, don't hesitate to send it back to the kitchen for further cooking.- Wash hands, kitchen work surfaces, and utensils with soap and water immediately after they have been in contact with raw meat or poultry.- Be particularly careful with foods prepared for infants, the elderly, and the immunocompromised.Created: 2009

Under a very high magnification of 12000X, this colorized scanning electron micrograph (SEM) revealed the presence of a large grouping of Gram-negative Salmonella typhimurium bacteria that had been isolated from a pure culture. See PHIL 10982 for a black and white version of this image.How do people catch Salmonella?Salmonella live in the intestinal tracts of humans and other animals, including birds. Salmonella are usually transmitted to humans by eating foods contaminated with animal feces. Contaminated foods usually look and smell normal. Contaminated foods are often of animal origin, such as beef, poultry, milk, or eggs, but any food, including vegetables, may become contaminated. Thorough cooking kills Salmonella. Food may also become contaminated by the hands of an infected food handler who did not wash hands with soap after using the bathroom.Created: 2009

See PHIL 10980 for a black and white version of this image. How can Salmonella infections be treated??Salmonella infections usually resolve in 5-7 days and often do not require treatment other than oral fluids. Persons with severe diarrhea may require rehydration with intravenous fluids. Antibiotics, such as ampicillin, trimethoprim-sulfamethoxazole, or ciprofloxacin, are not usually necessary unless the infection spreads from the intestines. Some Salmonella bacteria have become resistant to antibiotics, largely as a result of the use of antibiotics to promote the growth of food animals.Created: 2009
