F.tularensis‚ the causative agent of tularemia‚ is a small‚ aerobic nonmotile‚ gram-negative cocco-bacillus. Tularemia also known as rabbit fever and deer fly fever is a zoonotic disease that humans typically acquire after skin or mucous membrane contact with tissues or body fluids of infected animals‚ or from bites of infected ticks (Pal‚2007). Tularemia was recognized in Japan in the early 1800’s and in Russia in 1926. Tularemia as a biological weapon is the difficulty in culturing and growing

pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week to narrow down the scope of identification. Data has been presented in the tables

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

Corneal Ulcer (Introduction) The eye is one of the vital organs in a human being. As seen on figure 1‚ the eye is composed of many different parts and function. The cornea is a clear covering over the colored iris and the pupil of the eye. The function of cornea is to help focus light on the retina and protect the iris‚ lens‚ etc. so that the eye can see. The cornea is best to compare with a standard contact lens. Although‚ the function of a cornea is to protect from harmful microorganisms

Introduction This study approaches the understanding of the autosomal recessive “mini-muscle” phenotype in mice. Smaller body size and muscles as well as increased maximal oxygen intake are observed in mice with the “mini-muscle” phenotype. This observation raises an issue about why the selectively bred mice with the “mini-muscle” phenotype have reduced triceps and thigh muscle mass as they are able to cover greater distances; due to faster running speed‚ on an activity wheel compared to normal mice

the plate‚ it could be seen that the unknown had growth and formation of colonies. The Gram stain was chosen next to determine if the unknown was gram-negative or gram-positive. After looking at the gram stain under the microscope with the oil immersion it could be determined that the unknown was gram-negative due to the fact that the bacteria was pink in color and rod shaped. After determining the unknown was gram-negative‚ other bacteria’s were able to be eliminated from the options. The Triple Sugar
