Microscope and bacterial morphology?
914138
The greater the magnification, the more morphology you'll be able to see. 100x is preferable because bacteria are so small. Special stains help to see individual organelles inside bacteria, such as mitochondria, nucleus, cell membrane. Different bacteria take up different stains, which helps to identify them, such as gram positive and gram negative bacteria. The tubercle bacillus that causes tuberculosis will stain red on a blue background with the correct stain procedure.

Most light microscopes (or at least the ones I used) have a "arrow" in the eye lense that can measure specimens if aligned correctly. It also varied on magnification.

Yes. They are probably microbes or even smaller nanobacteria. \n\nI have seen the work of Dr. Robert Folk at the University of Texas, who examined the Martian meteorites found in Antarctica and found possible fossil evidence of nanobacteria. Many biologists are not convinced that nanobacteria (which are measured in nanometers) even exist and argue that they are too small to contain the functions of a living cell. The topic remains controversial.   \nHere is a page discussing the biological controversy (there are some geological controversies as well):\nhttp://serc.carleton.edu/microbelife/topics/nanobes/index.html\n\nHere is the NASA page describing the findings:\nhttp://nssdc.gsfc.nasa.gov/planetary/marslife.html

Bacteria are translucent so they must be stained to visualize with a light microscope. You can use numerous stains (crystal violet, methylene blue, safrinin) to color them so they can be seen.

When you used an optical microscope in biology class they usually have paramecia and amoeba that are alive and in a slide with a bubble for them to swim in. Most of what you see in biology study involves living cells.\n\nMost of what professionals see are dead cells that are stained to highlight certain features.\n\nOnly electron microscopes must only look at dead cells.

I didn't know the answer to this one myself, so I looked it up, wow, I can't write it all down here sorry.  But here are some sights I was able to pull up, hopefully you can find the info you would like here.  :)  Basically from what I have gathered though, they are broken down into four groups, compound, dissection, scanning electron, and transmission electron.  The last source I listed, has a guide to help you pick the right microscope for you if you are looking to buy one.  I'm not sure if any of this will help, but I hope it will.

If you are trained in microbiology you can tell by eye.  Plate out the bacteria (for single colonies) onto a universal media that is suitable for your target bacteria,  ie CLED, Maconkeys, Blood, Chocolate.  Incubate until there is a growth (usually 24hrs at 37 degreees celcsius is aerobic).  Look at the plate, are the colonies uniform in appearence.\n\nIf you are using liquid culture youu could use microscopy before plating out.  Either a gram stain or a direct (wet prep). This would let you know if you had all gram positives or all gram negatives or all rods or all  cocci or a mixture.  You would still have to plate out to make sure only one colony type grows.

they are cheap compare to electron microscope.\nbut there is limitation of zooming large.

Leeuwenhoek Microscope, pretty sure this is it. If you want a pic of it and description  visit the site i found on it.

Checked my bacteria program on my PDA and all that came up where....neisseria gonorrhoeae, neisseria meningitidis, moraxella catarrhalis and veillonella sp. \n\nFirst off, all I recall about those organisms is that they are aerobic cocci that are gram-negative. The exception being viellonella sp. as it is an anerobe. \n\nSecondly, I only looked for those traits I just mentioned, no idea if any of these meet your other criteria. \n\nThirdly, haven't you been doing tests all semester to narrow it down? The pathogens are limited to what you have studied, so it is not as the scope is that large. Try making a list of all of the organisms you have studied, turn it into a graph with all of the traits possible from all of the various tests...start filling in the blanks and you should have no problem figuring out which organism it is. Our specimen was contaminated and I found no problem determining both the assignment and the contaiminant using this method. \n\nPerhaps it is one of the organisms I mentioned above, it's very likely if you have studied any of them in Microbiology. But if not, use the method I described above and it really is just a process of elimination. \n\nGood luck

You can use a regular camera, but only if your microscope comes with a place to attach the regular camera. Basically all research quality microscopes do have a place where you can attach either a digital or a camera which uses film as long as it is a SLR camera and you can take the camera lens off (you basically attach the microscope instead of the lens in front of your camera). If you use a film camera, you may have to work out proper exposure times and be very careful with proper focusing. With a digital camera it is easier to check as you can look at the image you just took if it came out OK. Normally you can also attach digital cameras to a computer and see a large version of the image you took on the computer screen. \nYou won't get any good images holding a regular camera in front of an eyepiece like where you put your eye. For one thing it is difficult to hold the camera consitently in the correct place. Another is that light falling in from the side will be bad for the image quality. I think also the size of the image there may not be large enough to allow you to take an image of a high resolution.\nThere are also cameras you can buy which you can put onto your eyepiece instead of the ocular lens. They give decent images.

take your soil sample and suspend some in a little sterile water; plate out the suspension on agar plates in the usual way and isolate the colonies as a way to do a preliminary sort. Then maybe culture them ... Then do your in-depth analysis.

A definitive diagnosis requires demonstration or isolation of the organisms responsible for the infection. Direct Gram stain may be helpful because of the frequently unique morphology of Gram-negative anaerobic bacilli. In general, these organisms are pale staining and they may stain erratically. Fusobacterium cells may exhibit classic tapered ends and filamentous forms, with or without swollen areas and large round bodies. Direct gas-liquid chromatography of clinical specimens occasionally provides important clues to the presence of certain Gram-negative anaerobic bacilli. A large amount of butyric acid in the absence of isobutyric or isovaleric acid indicates the presence of Fusobacterium. The presence of succinic acid and only Gram-negative rods seen on Gram stain, or of both succinic and isobutyric acid in the specimen, indicates that Bacteroides is present. Both direct and indirect fluorescent antibody techniques may be useful for rapid detection of Bacteroides, Prevotella, and Fusobacterium in clinical material.
