Premium Bacteria Microbiology Escherichia coli
The Escherichia Coli bacterium was discovered in 1885 by bacteriologist Theodor Escherich. He found the bacteria in the human colon and showed that some strains of Escherichia Coli were responsible for infant diarrhea and gastroenteritis. The Escherichia Coli was originally named Bacterium Coli. The name was changed to honor Theodor Escherich. E coli are normally harmless and are part of the normal flora found in the lower intestines of humans and healthy cattle. Some E. coli serotypes are known

Introduction The Gram stain is one of the most useful staining procedures in microbiology . It is one of three differential staining techniques‚ is used to identify divide bacteria into two groups: Gram-positive bacteria and gram-negative (Madigan‚ Martinko‚ Dunlap‚ Clark (2009). These staining reactions take advantage of the fact that cells or structures within cells display dissimilar staining reactions that can be distinguished by the use of different dyes (Brown 2009). A gram positive bacteria

Lab Report #1: Observing Bacteria Microbiology Abstract: This lab exercise familiarized the student with the use of a microscope by observing and identifying various different slides under the microscope. The student practiced observing the given slides under the 10x‚ 40x‚ and 100x (oil immersion) objective lenses‚ which allowed for the identification of the different organism’s shapes and sizes. Purpose: The aim of this exercise is to equip the student with the knowledge

It will be imperative for the ownership to take up on this research proposal‚ because if the findings result in the fact that there is a possible correlation between the reports and the decline in sales‚ the ownership will possess the necessary information to make substantial

Swarming was observed on plate D. E has an abundant growth of gram-negative‚ 2mm circular blue-green colonies with diffused green pigments. E gave off a pungent odour and have a mucoid consistency. No growth was observed for F. When grown on blood agar under aerobic conditions‚ A had abundant growth of 1mm white‚ circular‚ moist colonies

Grams staining method and reliability of this method. According to me‚ Grams staining process is a simple technique that assists in recognition of etiological agent and therefore can be called as one of the most significant staining practices in microbiology. Though‚ Gram is concerned that the staining process developed by him is imperfect because not all bacteria can be stained by it‚ but in my opinion‚ when we pour ethanol over the slide to wash away the dye then only definite bacteria can retain
