Microbiology study group spring 2009

Published

Just wanted to Start a study group for spring semester .I thought it will also be fun to give pop questions for us to make up from our classes and answer to help us learn more. Hope to hear from u guys

Man, I'm in my third week of class and still don't feel like we've covered many of the interesting things others have!

My prof for lecture is from Russia and has a thick accent, so a little hard to undrestand at times, but he really seems to know his stuff and is funny. Says we will be covering the book from front to back, no skipping of chapters or sections. For anyone using the Torte, Funke Intro to Micro text, we are just starting chapter 4. Our first exam is next Monday, hope I do well! The prof for our lab is much more laid back, nice guy. Had us learn how to use the brightfield microscope and then viewed slides of e-coli, yeast, and mixed bacteria.

Well, everyone. Count me in, as well! After reading some posts, I feel way behind. Tomorrow is actually our first real lecture as the professor spent the first day going over the syllabus. I wanted to get a jumpstart on reading, but a fellow classmate offered a book for sale, and I couldn't pass up the offer--$60 for a book that cost $134 new! I just had to wait until tonight to get it. It's all good. I'm about to go crack it open!

tfleuter, Good luck on your exam! (I have the same book) and our exam is for Ch1-5 in a couple of weeks.

We have just completed one full week and have covered:

History of Microbiology

Golden age of microbiology

4 Major groups of Microorganisms

Differences betweek Eukaryotes and Prokaryotes

I am off from work and school and I will be trying to review the material and listen to the lecture that I tape at least 2 times. The first exam isn't until Feb but it is 100 questions!

I had first day of class this afternoon. We also completed Histology of Microbiology and Golden age of Microbiolody. It is great that you are allowed to tape the lecture. One of the classmates asked about taping the lecture, the instructor said NO. And also he laughed everytime before he said something. I guess he laughed more than we all 30 stduents did.

we are two lectures, and two labs into it now. we have done golden age, important contributors, ie., lister, etc, we have gone over chemical makeup of cells, which totally sucks b/c I had a&p and chem so long ago, i need to brush up. (i took a two year LOA due to a rare, severe illness), the makeup of dna and rna, sugars, lipids and proteins. In the lab we have done simple stain and negative stain. for the negative stain, we brushed our teeth and smeared the slide w/it and got to observe bacillus subtillis and staphylococcus epidermidis. I enjoy lab immensely, but it always seems so rushed, b/c we have an hour and 15 min, and there is a class before and after this lab so you can't get there early to go over stuff. I guess I will have to get in on a weekend before the lab practical, which isn't until the first week of may anyway. There are only two lab practicals, and unknown research paper, and a food from home experiment/paper.

Just finished 3rd week (for lecture, 2nd week for lab) today. We have just started going over microbial metabolism. I remember going over some of this stuff in biology a year ago, but it's definately more in depth this time around.

I'm avg about 90% on our weekly quizzes, Hopefully I can bring that up a bit, I really want to leave this class with an A.

Hey guys, I'd be interested to see who can answer the following clinical application questions. (For those who are using the book by Tortora, Funke and Case 9th edition this question is a clinical application question at the end of Ch.1)

The prevalance of arthritis in the U.S. is 1 in 100,000 children. However, 1 in 10 children in Lyme, Connecticut, developed arthritis between June and September in 1973. Allen Steere, a rheumatologist at Yale University, investigated the cases in Lyme and found that 25% of the patients remembered having a skin rash during their arthritic episode and that the disease was treatable with penicillin. Steere concluded that this was a new infectious disease and did not have an environmental, genetic, or immunologic cause.

a)What was the factor that caused Steere to reach his conclusion?

b)What is the disease?

c)Why was the disease more prevalent between June and September?

Ok, here's my guesses:

a) I'm not completely sure but I think the high number of children in Lyme CT that developed arthritis during a ceratin time frame (summer/tick season.) That fact that the the dz was treatable with penicillin rules out genetics and points to a bacterial dz.

b) Lyme's Disease

C) Warm weather, height of tick season

ok i have some study questions to ask you guys! what stain could be used to detect Bacillus anthracis in a terrorist attack? why when a human is infected with streptococcus can get a shot of penicillin that will destroy the Streptococcus but not harm the human? and why when a person has Mycoplasma pneumoniae it is not harmed if the patient is given a shot of penicillin?

1) You could use a Gram stain to identify bacillus anthracis.

2) Penicillin will destroy the gram positive streptococcus because it contains exposed peptidoglycan in its cell wall. Penicillin binds to proteins that synthesize the cell wall which prevents glycan cross-linking. Humans do not have peptidoglycan in their eurkaryotic cell walls so penicillin will not harm humans.

3) Penicillin can not destroy mycoplasma pnemoniae because this bacterium does not have a cell wall. Again, penicillin inhibits the synthesis of peptidoglycan, which is only found in a bacterial cell wall.
