ANTI-INFECTIVES Anti-infective agents are drugs that are designed to act selectively on foreign organisms that have invaded and infected the body of a human host. Ideally‚ these drugs would be toxic to the infecting organisms only and would have no effect on the host (or human) cells. OVERVIEW • Antimicrobial therapy (often termed “antibiotic therapy”) is the use of medications to treat infections caused by bacteria‚ viruses‚ and fungi. • Antimicrobial must use selective toxicity to kill

E. aerogenes were positive for this test while P. aeruginosa was negative. Results for P. vulgaris were negative for this test‚ but this bacteria can show positive or negative for the Ornithine‚ The lactose fermentation test (MAC) showed that the unknown was positive for lactose fermentation. Expected results showed that all bacteria should have been positive for this test. However‚ the test on P. vulgaris during the experiment was negative‚ defying expected results. The oxidase test was used

The aseptically inoculate nutrient broth tubes A and B did not have any microbes inoculated into the tubes so it should not have been cloudy and that was what was seen. Tube C should have been cloudy because it had E. coli inoculated into the nutrient broth and that was also seen. A simple streak was also performed and it looks has if the loop went over previous streaks which should not have been done. A complex streak was also done. No colonies grew towards the end of the streak‚ this could be due

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

observed protein catabolism in Entrobacter aerogenes and Proteus vulgaris. We inoculated tubes with each bacteria‚ one containing a nutrient gelatin and one a urea agar medium and incubated the tubes‚ at room temperature and observed the growth and the color to determine whether hydrolysis took place. (Table 3) * To observe protein catabolism we also inoculated one tube with Enterobacter aerogenes and the another Proteus vulgaris‚ allowed them to incubate and observed the growth and color changes

The microbes that were tested during this lab were: Escherichia coli‚ Bacillus cereus‚ the unknown‚ Proteus vulgaris‚ Staphylococcus epidermis‚ Enterobacter aerogenes‚ the control‚ and Pseudomonas fluorescens. The microbes tested during these various tests were looking for which would: reduce sulfur/produce sulfate‚ produce indole‚ or possess motility‚ reduce
