Bacteriology

Jaqueline Moreira Biology 23 March 8, 2016 Pseudomonas aeruginosa Introduction P. aeruginosa belongs to the family called Pseudomonadaceau ( Willey, J., Prescott Microbiology, 2014, p.527). P. aeruginosa is a gram negative bacterium. The shape of this particular bacterium is straight or slightly curved rods, but not helical. The size of this bacterium is about 0.5-1.0 micrometers wide and 1.5-5.0 micrometers long. The arrangement is single, but as is starts to age it forms cysts. P.…

He graduated from Medical school Harvard in 1912. He began working at the Laboratory Wassermann, was the laboratory for the Department of Health. In 1918 he was appointed professor of Preventive Medicine and Hygiene. He began teaching there bacteriology and immunology in 1921 until 1946. Hinton as professor of medicine,…

The spread of tuberculosis in society changed the way medicine was approached to a more scientific focus. The disease also shifted the idea that the sick should not be helped to one more focused on community. Malcolm Morris calls for a “crusade against tuberculosis” in his article titled “The Prevention of Consumption.” In the article, Morris focuses on the way tuberculosis is transmitted, action by public authorities, sanatoriums, and the help for all people as ways to combat tuberculosis.…

of elimination in a scientific study. To do this, many different tests were completed to help rule out species that were provided on a sheet of paper listing the possible candidates for the unknown microbe. The Bergey’s Manual of Determinative Bacteriology flow chart was also used to narrow down choices as tests were completed, along with a flowsheet of gram positive and negative microbes provided in Microbiology Class. To begin the process of identifying unknown microbe #7, two isolation…

of Medicine, Bachelor of Surgery. Under the guidance of bacteriologist Sir Almroth Edward Wright, who revolutionized the idea of vaccine therapy as a medical treatment, he became a researcher in a bacteriology group at St. Mary’s Hospital Medical School. In 1908 Fleming received a degree in bacteriology and the Gold Medal for top student (Biography.com Editors). During his years in medical school, Fleming became particularly “interested in the natural bacterial action of the blood and in…

modern day medicine. Alexander Fleming was born in Scotland but moved to London to go to school. While there he joined the army. When World War I came along,he was the assistant to a bacteriologist. This is where he became interested in bacteriology. With the information they gained, they tried to make the soldiers practice better hygiene. He wanted reduce the amount of soldiers that died of infection like trench foot. It wasn't until after the war that Fleming…

Dacryocystitis , the inflammation of lacrimal sac and duct has been known from the earliest times due to its grosser manifestations involving cosmetic defects on face. For a long time, swelling near the medial canthus was considered as a soft tissue infection known as “Aegylops”. It was in the middle of the first century that it could be recognized as a disease of the lacrimal passage when Versalius and Fallopius22 described the lacrimal sac with accuracy. George E Stahl23 showed that the…

Bacteriology, study of bacteria, dispelled the blindness of the animal diseases. Although, it was long known that animal products such as meat and milk could causes illness, it only pertained to the process of decomposition not the actual animal itself. Bacteriology discovered the specific agents that connected animal and humans diseases. This took a while to uncover because contaminated…

Serratia genre includes Gram negative rod- shape bacteria, aerobe facultative anaerobe and chemo-oganotrophic with low nutrional requirements. According to Bergey’s Manual of Systematic Bacteriology, Serratia genre belongs to the Enterobacteriaceae family and includes 12 species 1,2. They are widespread in the natural environment, being isolated from soil, water and different plants (vegetables, mushrooms, grasses, mosses, trees)1,2,3. Serratia marcescens grows at 37°C, but it can grow in…
