previous isolated and identified MRSA and VRSA S. aureus isolates, four MRSA+VRSA and four MRSA+VSSA isolates were chosen for MIC and MBC experiments. With a sterile loop, a loopfull from each chosen isolate was inoculated from the BHI slant into MH broth then incubated with shaking at 37°C overnight for 24 hours. The concentrations of these suspensions were adjusted to be equal to the 0.5 McFarland standards by adding a sterile saline. Test and standard tubes were compared against a white…

This lab experiment was completed to determine the environment in which microbes prefer to live. The pH, moisture, available nutrients, oxygen and light all affect the rate in which bacteria grow. The majority of bacteria flourish when the pH level is near neutral; the growth rate is highly affected if the pH is off by just a little. If too acidic, the amount of time it takes the bacteria to adjust to a new environment (lag time) is increased which slows the growth, the activity of enzymes is…

Louis Pasteur was a very famous chemist and microbiologist born on December 27, 1822. He was born in Dole, France. Pasteur was roman catholic and considered to be an average student, he loved to paint and draw. Louis’s father was a tanner and served in the Napoleonic wars. Later, in 1840, he earned his bachelor degree in arts at the Royal College of Besançon. Then, in 1847, he earned another bachelor's degree in science. In 1848, he actually became a professor of chemistry at the University of…

Infectious Coryza Limited by the knowledge of microbes, infectious coryza was not regarded as a distinct avian disease until 1920s. In 1932, the causative agent was isolated and named as Haemophilus gallinarum afterwards. Based on the identification of Page in 1960s, H. paragallinarum was isolated and regarded as the true causative bacteria. However, recent researches have confirmed both these two species belong to Avibacterium genus and are both reason for the fowl coryza, while most researches…

of resistance to commonly prescribed drugs (Jenkins and Schuetz,2012). The most-widely used tests in clinical laboratories include Manual: Broth Microdilution, Disc Diffusion and E-test. Automated instruments: MicroScan walkaway, Vitek2 system and PhoenixBD tests are commercially used. Manual:…

the streak, and the plate was incubated at 37C. The next test performed was the Bile Esculin Test. A bile esculin agar slant was inoculated with the unknown, and incubated at 37C for 24-48 hours. A 6.5% Salt Broth Test was conducted by obtaining a tube of 6.5% salt broth, inoculating the broth with the unknown, and incubating it at 37C. For a catalase test, a small amount of unknown was transferred onto a slide. A drop of H2O2 was then added to the slide, and observations were recorded. A…

marker and label the antibiotic name (gentamicin, novobiacin and penicillin) in each section. -Remove the lid of the active S epidermis broth, flame the lip of the tube with help of the tea light candle and careful remove the sterile swab and submerge the swab into the active S epidermis broth. -Swab the entire agar plate including the edges and let the active broth absorbed in the…

of four phases. To start with, the suitable media need to be identified for the growth of Av. paragallinarum. Secondly, the media used in disc diffusion and broth dilution testing need to be validated. This validation process is completed by performing disc diffusion and broth dilution testing of quality control strain on candidate agar or broth. Then, the antimicrobial sensitivity of Av. paragallinarum can be tested on validated media, by both disc diffusion and dilution method. Any antibiotic…
