- Not only is blood agar an enriched medium that can support fastidious organism growth, but it can also serve as a differential medium in the identification of streptococcal species because of the presence of red blood cells that can be destroyed by an organism's hemolysins. Looking at this photo, how could you describe the organism growing on the surface of this blood agar plate? Multiple Choice a) Gamma-hemolytic b) Alpha-hemolytic c) Non-hemolytic d) Beta-hemolyticExplain why the media where the Staphylococcus aureus is plated has turned yellow but the media where Staphyloccocus epidermidis plated is still pink? The media used would be the Mannitol Salt Agar Medium.Why do Salmonella growing on XLT-4 agar is red colony with black center. Explain it in detail and concisely.
- Pseudomonas Aerogenosa has the ability to use pilus as a motility structure How does Pseudomonas aerogenosa contribute to the virulance of the pathogen?Is the telluride glycine agar? (TGA) a complex or defined medium? Explain based on its composition. What kind of Media is TGA explaining based on what kind of microorganisms it allows to grow?A pure culture of an unknown bacterium was streaked onto plates of a variety of media. You notice that the colony morphology is strikingly different on plates of minimal media with glucose compared to that seen on trypticase soy agar plates. How can you explain these differences in colony morphology?
- Does the Gram stain provide information regarding a bacterium's susceptibility to antimicrobial drugs? explain your answer?Kindly fill in the data table attached below. Microorganism: Entamoeba histolytica If gram reaction is not applicable, kindly specify.The figure attached shows the colonies on Eosin Methylene Blue Agar (EMBA) plate. Make a description on the picture.
- Why is Salmonella typhi a gram negative bacilli? Explain.Given the illustration and values below, determine the concentration of the original sample. Report results in CFU/mL or colony-forming unit/milliliter. Note that in order to observe the accuracy of results, culture plates with countable colonies between 25-250 CFU are considered in standard bacterial plate count."If you find purple colonies with metallic green sheen growing on your EMB plate following an inoculation with a urine sample, most likely they belong to " Proteus vulgaris Escherechia coli Pseudomonas aeruoginosa all of these
