Gissela Ruiz Histopathology terms Dr. Agapito Reference: E. Gupta, P. Bhalla, N. Khurana, T Singh, “ Histopathology for the diagnosis of infectious diseases” Indian Journal of Medical Microbiology. (2009) 27(2):100-6. Questions: 1. What is Histopathology? Histopathology is the examination of a tissue biopsy to try and find the cause of the infected organism. 2. What is the importance of a Histopathological Examination? The Importance of a Histopathological examination is to try and find a…

test includes: Gram Stain, SIM, Sucrose, Citrate, MAC, and EMB. Each one of these test are different and they will give a positive or negative feedback which is how we will know which bacterium I have. A gram stain is one of the most use stain in microbiology. The purpose of a gram stain is to divide microorganisms into gram positive or gram negative. In this procedure you will use Crystal violent, Iodine, Acetone, and Safranin. You use different dyes because Gram negative microorganisms have a…

antibiotics, susceptibility testing is essential (Bush 2014). One recent study shows 50% of HIV/AIDS patients had severe sepsis at ICU admission or during the ICU stay. An astounding 90% of nosocomial infections were the source of sepsis and the microbiology of infections was mostly gram-negative rods Serratia marcescens (three) made up 7% (Japiassú…

be used for making certain foods or antibiotics. Also, it can lead to many new discoveries such as new species or evolution of new species. This study is done by applying all of the methods and techniques that have been learned and used in the microbiology laboratory for the identification of the unknown bacteria’s. In this experiment, multiple of tests were conducted to provide the fermentation abilities, existence of specific enzymes, and certain biochemical reactions. Observations obtained…

One, morning as my father was dropping me off at my elementary school I had asked: “Can you bring me lunch today?” His face had to turn doubtful that he has going to disappoint his daughter. “I don’t have-“, his reaction had turned on the light bulb. He twisted his body around the seat to grab a dirty brown paper bag and hand it to me. Inside were his usual lunch, a tuna kit, and a mountain dew. “Thank you, daddy, I Love you!” I jumped off my seat gave him a kiss and ran off to school. My father…

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 streaks of the mystery microbe were made in order to determine whether the microbe likes to grow at 30˚C or 37˚C. It was discovered that the microbe likes to…

The rabies virus has already survived for hundreds of years and is often fatal. The are 71 different species in this pathogen's family with 11 genera. The genus I identified is the lyssavirus from the family Rhabdovirdae. The species of the family Rhabdovirdae, I found on this farm in Montana, was rabies. Animals and humans can be a host to this virus. It is a zoonotic disease prevalent in wildlife, and the main animals involved vary between continents. In North America the main animals involved…

For centuries, tuberculosis was thought to be an insidious, implacable theft of life, the germ of death itself. When a person was diagnosed with tuberculosis it was like a death sentence. Its cause was unknown until in 1882 German physician and scientist Robert Koch discovered the bacterium that causes the disease, Mycobacterium tuberculosis. This discovery has contributed to many other important events across multiple scientific disciplines. It is what lead him to receive the Nobel Prize and is…

My hypothesis was supported because I was able to use the five I’s of microbiology to narrow down my two unknown microbes. My first unknown which is the yellowish one was rod shaped however on the table that was provided states that the yellow microbe should have a coccus or tetrad shape. This was hard to identify because it…
