What Is Microbiology? Microbiology is the study (logy) of very small (micro) living (bio) things. Microbiology is the study of microorganisms. These "bugs" include: bacteria (that’s the Latin plural for bacterium); viruses (that’s the non-Latin plural for virus - virii sounds weird‚ so I don’t say it); and‚ fungi (that’s the Latin plural for fungus - which by now you have guessed‚ or already knew‚ and may not be all that interested to know‚ anyway). Microbiology is actually made up of several

you in trouble. This is especially true in Microbiology. The techniques you will be learning tonight‚ if mastered correctly‚ will make your life and learning experience in Microbiology much easier‚ if you don’t pay attention and practice these techniques incorrectly‚ well then……? Today you will be learning the following techniques: 1. Streak plate method for colony isolation 2. Aseptic transfer techniques First the streak plate methods. In Microbiology it is often necessary to isolate pure colonies

Microbiology Laboratory Report Identification of Unknown Bacteria 6O BIO 251-7H1 Gram Stain Summary: Out of 28 Unknown microorganisms‚ slant 6O was randomly selected‚ and subjected to testing in order to identify it’s species. Seventeen of the unknown bacteria were classified as Gram-negative bacilli: Corynebacterium pseudodiphtheriticum‚ Enterobacter aerogenes‚ Eschirichia coli‚ Flavobacter capsulatum‚ Helicobacter pylori‚ Klebsiella pneumonia‚ Klebsiella oxytoca‚ Proteus hauseri‚ Proteus

Discussion The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order

Sarah Helms Thursday/ 11:15am #1 Escherichia coli There are many types of microorganisms and ways to treat each one. Knowing the differences of each is vital to treat a patient correctly. The purpose of this report is to explain the process and steps used to identify a certain microorganism referred to as the unknown. Materials and Methods A test tube with an unknown microorganism will be retrieved. Once the test tube is retrieved‚ a steak for isolation will be completed in order to produce

acne treatment’s amazing end products. The question is‚ which antimicrobial treatment‚ Proactive™ or Clearasil™‚ will kill more bacteria and have a larger inhibition zone when exposed to bacteria? My hypothesis is‚ if I expose Clearasil™ to Escherchia Coli and Streptococcus Epidermis‚ then it will kill more bacteria and have a larger inhibition zone‚ than Proactive™ will. Experimental Design Materials Needed for this experiment‚ is a container of Proactive™ and a container of Clearasil™
