worldwide annually. These occur mostly in developing nations among children five years of age1,5. An estimated 1.1 million people die from Shigella infection globally each year. Sixty percent of these deaths are among young children5. According to the Centres for Disease Control and Prevention(CDC), epidemic dysentery in developing countries is usually caused by Shigella dysenteriae serotype 1 (Sd1). Sd1 is an unusually virulent enteric pathogen that is most common cause of large-scale, regional outbreaks

of multi drug resistant strain shigella sonnei from its ancestor E. Coli and predecessor S. Flexneri and its spread to Vietnam Introduction Shigella is a genus of Gram-negative, facultative anaerobic, nonspore-forming, nonmotile, rod-shaped bacteria. The genus is named after Kiyoshi Shiga, who first discovered it in 1897. The causative agent of human shigellosis, Shigella causes disease in primates, and is the only naturally found in humans and apes. Shigella is one of the leading bacterial

(Longe 3378). This bacterium, Shigella dysenteriae, named for the man who discovered it, is one of four serogroups of the Shigella species, and is known to be found worldwide. Of the other three serogroups, Shigella sonnei is known to cause about 70% of the reported cases of shigellosis in the United States and other developed countries. In developing countries, Shigella flexneri is the most widespread. Shigella boydii is the most genetically diverse of the Shigella species, with some subgroups

Since the discovery and identification of viruses, scientists and physicians have been coming up with ways to combat bacterial illness. One physician in particular, Felix d’Herelle, was truly dedicated to finding a remedy for the bacterial illnesses, primarily the flu, spreading among French soldiers and civilians during World War I. Since no resolution existed at the time for these critically ill soldiers and civilians, many casualties occurred around this time. In 1917, Herelle unveiled the underlying

This species of Shigella has been found to have a negative result for lactose fermentation. However, its ability to ferment lactose is described as late fermentation (Acharya, 2013). Therefore, test results may come back positive due to the variability in the incubation

Foodborne illness diseases that spread through food or beverages are a common, distressing and sometimes a life- threatening problem for millions of people in the United States and around the world. One of the largest foodborne illness outbreaks in United States history happened in 1977. This foodborne illness was called botulism which is a serious and rare disease caused by food. The cause of this outbreak was hot sauce that had been made from improperly canned jalapeno peppers. Foodborne illnesses

color of the media should stay the same. There should be no growth in the colony, and it should be lactose negative. In the Mannitol Salt Agar, the color of the media should be the same, and there should be no growth in the colony. In the Salmonella Shigella Agar, the color of the media should be the same. There should no growth in the colony, and it should be gram negative. From the results of the lab for P. aeruginosa in the Blood Agar, the color of the media stayed the same. The color of the colony

Cocci has a spherical shape, Bacilli has more of a rod shape, and Spirillum has a spiral shape. They all consist of different gram stains such as Cocci can be gram positive in young organisms and might be gram negative in older organisms. Spirillum is gram negative and Bacilli is gram positive. Group B- All of Group B consist of Staphylococcus aureus and Clostridium botulism. Staphylococcus aureus is a small-round shape organism that is gram positive. Clostridium botulism is a rod shape and gram

bacteria was run through fourteen tests to determine morphology, fermentation properties, reducing and oxidative properties, and other various characteristics of each isolated unknown. It was concluded that the sample contained Lactococcus lactis and Shigella flexneri. Introduction It is fascinating to look around and see how much diversity exists on earth. Perhaps even more interesting is the diversity that exists far beyond the naked eye. Over the past several decades, it has been determined that
