Microbiology Definition and 24 Threads

I’m male, my nature has always been to question everything explore possibilities, over my latter years convinced that for the short period of time we existed we gained very little, if we did stay around a little longer we may learn a little more, what we cannot prove to be correct is where we...

Explain the difference No equation Couldn't figure it out!

This snip off is from Himedia Widal test teaching kit. I understand 1/20 1/40 1/80... are the concentrations in each test tube. They are obtained by the following calculation: (2nd testube) 1/2 X 1/20. But I can't decipher the numbers written at the top, 10-1 , 10-2 etc. Besides which of of...

Is there a database that can help answer this question? Any references? Thank you!

Homework Statement I have done tests on this unknown bacteria and this were the results: Cocci shape Gram (-) negative Catalase (+) positive (only one bubble though) Oxidase( - )negative Has endospores (used Schaeffer-Fulton method) Antibiogram: Resistant to Streptomycin...

Hello! I've been working on a few soil based MFCs and I have been monitoring my voltage and energy output for a week now. I've made the electrodes by covering stainless steel metal meshes with activated carbon using epoxy. I've gotten some funky results as attached. As you can see... the...

< Mentor Note -- OP has edited the thread to add the HH Template -- Thank you! > 1. Homework Statement I think that the spores produced by the bread mould plant are actually its seeds but my textbook says that it isn't. Homework Equations No any equation to mention The Attempt at a Solution I...

Homework Statement I need help creating flowchart for ID-ing an "unknown" organism. Unknown in quotes because I already know ID of organism. Homework Equations gram + (purple) tetrads and cocci forms yellow colonies on NA plate catalase + coagulase - Nitrate + oxidase (weakly) + Bacitracin...

Hello! I am a sophomore with a major in microbiology; my future goal is to attend the graduate school with virology/medical microbiology program and become a virologist specialized in the influenza & VHF viruses. Currently, I am taking the Organic Chemistry I, Immunology (graduate-level), and...

Hello! I am a rising sophomore with a major in microbiology. I wrote this post to seek out the advice from you in terms of double majoring with the mathematics. Although my primary interest is on the microbiology (especially the virology), I am also deeply interested in the fields of number...

Hello! What calculus textbook do you recommend for microbiology major or other biology majors? I heard good things about Stewart, Spivak, Larson, and other legendary calculus textbooks, but I do not know which one is suited for the microbiology major. I really like to have one that is...

This was a quiz question recently in my microbiology class: In what way are transcription and DNA replication compartmentalized in eukaryotes? a. they occur in the same compartment b. they occur in separate compartments c. one must be finsished before the others start d. they are...

Hello everyone. I'm studying to become a laboratory analyst and I've recently began my studies in microbiology. My studies began with chemistry and now that the focus in my studies has shifted to microbiology for a bit, I see a sudden drop in required accuracy in results of our analysis. I'm...

Homework Statement I have some test results such as gram staining or urease tests to identify a bacteria. How do I figure out which tests are "first stage" tests and which ones are "second stage tests". Because based on the results of the test, I need to figure out which ones are needed and...

I am currently a 1st semester freshman at my state university. I am a Microbiology/Biotech major. My degree requires 7 chem classes, 2 physics, and then a handful of biology classes in my concentration (not including a handful of general biology classes). I really like microbiology, but this...

hey there...just wondering if I can get some suggestions choosing the sub I want to grad. from.. The thing is that I just finished my high school n now got chance in both Mechanical Engineering n Microbiology...I think I'm pretty good at Physics..n also in Math n Biology...tho I really don't...

Microbiology major for pre-med? I just have a quick question for you guys. I have recently been accepted to the University of Iowa and I picked to major in Microbiology. Would this be a good major for someone who is considering going to med school? Are there any pros and cons? Thanks for any...

Need help Microbiology! how is a clinical specimen processed to identify the microorganism present in it. What are the important considerations for ensuring the quality of the specimen?

yea so some disinfectants work better at certain concentrations such as 70% etoh as opposed to 100% etoh. what is the reason for this? this is a question pertaining to microbiology btw. thanks.

Calculate the time it will take to increase the cell number from 10^4 CFU/ml to 10^8 CFU/ml assuming a generation time of 1.5 hr. 2=e^ut where t is the generation time...solve for u. x=xo*e^ut where t is time For the 1st equation: ln2=lne(ut) ln2/t=u ln2/1.5=u u=0.46 l/hr For...

I used a white tray to work on for my antibiotics investigation. What is the tray called? :frown:

Do all, most, some, or zero unicellular organisms have a sense of touch? Do they know when they run into something? If they do, how does that sense of touch work? is it pressure in the cytoplasm, sensors at the membrane, or something else? Also, do they have other sensory capabilities? I am told...

Hi everybody, I'm about to apply for a program in molecular medicine and need to freshen up my Physics for the admissions exams... haven't had any Physics for 2-3 years :rolleyes: so I guess I'd better get busy. Most of the final score is math, chem and biology anyway (which I enjoy), but...
