Proteus mirabilis The genus Proteus‚ according to Bergey’s Manual of Determinative Bacteriology‚ is a group of straight rod Gram negative bacteria around 0.4-0.8 μm in diameter and 1-3 μm in length. In the microscopic test done‚ it was seen that the unknown culture contained rods that are on the shorter side‚ thus was identified as bacteria that appear to be coccobacilli. Because of the presence of peritrichous flagella‚ species included this genus are motile and most strains swarm in periodic cycles

(Antonie van Leeuwenhoek) Anthony van Leeuwenhoek was born in Delft‚ Holland on October 24‚ 1632 to Philips Thoniszoon‚ a Dutch tradesman that made baskets‚ and Grietge Jacobs‚ the daughter of a brewer. He is also commonly known as "the Father of Microbiology"‚ and considered to be the first microbiologist. They lived in a comfortable home until his father and two of his sisters died when Anthony was just eight years old. Also‚ his mother was left with five young children. Therefore‚ Anthony was sent

Name of Student: Bal Krishna Maharjan Course: Food Microbiology 17/FA Describe how to isolate and differentiate between molds and yeasts? Answer: Isolation of molds: Isolation of molds can be done in two ways: 1. Direct isolation: Under this different methods can be selected depending upon the nature of molds and need of study. The following are the different direct isolation techniques. a. Direct transfer: Involves simple transfer of a mold from its source to a pure culture‚ usually consists of

Title: Chapter 7: Bacterial Growth Purpose: The purpose of this experiment is to observe the bacterial growth of Escherichia coli under various conditions. Physical factors and nutritional requirements determine the overall concentration of the bacteria. Along with the use of a spectrophotometer and the technique of serial dilution‚ countable colonies can be obtained. Results are plotted on a semi-log graph in order to observe the different growth curves corresponding to optical density (cell

Pseudomonas aeruginosa Pseudomonas aeruginosa is the bacteria of my initial unknown project. Determining which bacteria I had was completed by many steps. The one fact that I had‚ was that it was a gram negative bacteria because on the gram stain it appeared pink. Its cell wall is composed of a plasma membrane‚ periplasmic space‚ peptidoglycan and an outer membrane (lipopolysaccharide and protein). By looking at the agar plate it was easy to tell that it was not a swarmer and it did not have any

Lab Practical One Report Unknown Bacteria Staining Gram Acid Fast Spore The first practical for microbiology was staining of an unknown bacteria. Professor Goode provided an unlabeled bacteria in which each individual were to conduct gram‚ acid fast‚ and spore staining tests from memory. When the gram staining test was conducted a positive results was obtained. When views on oil bacteria appeared purple and rod-like. I noted this result and looked at the lab key to see what the results narrowed

MICROBIOLOGY SECTION The microbiology section aims at studying yu ailments and diseases from the isolation of suspected causative organisms. The processes involved in the isolation of these organisms include; culturing‚ staining‚ microscopy and sensitivity tests. Samples collected for examination include; stool‚ blood‚ sputum‚ urine‚ vaginal swab‚ wound swab and wound biopsy. Bacterial Culturing and sensitivity Cultures are carried out to isolate suspected organisms from a sample. There are different

The human body is said to be compose of approximately a hundred trillion cells‚ connective tissue contributes to about forty five percent of the total cell weight. It was nicknamed the flesh eating bacteria because the victims injuries would have a rotting appearance. What are the pathogens that cause this disease? Necrotizing
