Got any pictures of the Macro world ?...In all their awe and splendor some of the most beautiful things can only bee seen with a microscope !

Mycoplasma pneumoniae

Mycoplasma pneumoniae is a very small bacterium, in the class mollicutes. This class of organisms lack a peptidoglycan cell wall present on all other firmicute bacteria. Instead, it has a three layer cell membrane which incorporates cholesterol compounds, similar to eukaryotic cells. Lacking a cell wall, these organisms are resistant to the effects of penicillins and other beta-lactam antibiotics, which act by disrupting the bacterial cell wall.

M. pneumoniae has one of the smallest genomes known, with 800 kilobase pairs (kbs). Its genome and proteome has been fully characterized. It uses some unique genetic code, making its code more similar to mitochondria than to other bacteria. It lacks the cellular machinery for making many essential compounds. Because of this, it is an obligate parasite. No mycoplasma is found free-living. In this respect, mycoplasma is more similar to viruses than to bacteria.

M. pneumoniae is spread through respiratory droplet transmission. Once attached to the mucosa of a host organism, M. pneumonia extracts nutrients, grows and reproduces by binary fission. Attachment sites include the upper and lower respiratory tract, causing pharyngitis, bronchitis and pneumonia. The infection caused by this bacterium is called atypical pneumonia because of its protracted course and lack of sputum production and wealth of extra-pulmonary symptoms. Chronic mycoplasma infections have been implicated in the pathogenesis of rheumatoid arthritis and other rheumatological diseases.

Second generation macrolide antibiotics and second generation quinolones are effective treatments. Disease from mycoplasma is usually mild to moderate in severity.




   
Mycoplasma pneumoniae On the surface of a cell - M. pneumoniae is a common cause of mild pneumonia. This bacteria is unusual in that it lacks a cell wall.

A few pictures of human cancer cells i've taken....

This one is human breast cancer cells.  green is staining the protein "E.Cadherin"  cell uses the protein to attach to and move on surfaces, which is why you see it around the edges of the cell, and concentrated where the cells are toughing one another of the slide they are growing on.  blue is the nuclei and red is the cellular skeleton:

this one is human lung cancer cells.  these cells are stained for E.Cadherin as well (green) but the cells are shped differently, and grow in a perfect alttice with eatchother, so you see the different pattern of the same protein in different cell types.

breast cancer again, different protein stained in green this time.  this one localizes mainly in the nuclei so you see it in a different place.  red is once again the cells skeleton.

the cameras just don't do these flourescent dyes and antibodies justice.  they are SO pretty when you actually see them in the microscope.  i love my job!!!!

Posting this now to remind myself to come back to this thread and post some photos I have when I get home.  I was bored some time ago and I was explaining to a guy how nasty paper money is (who apparently never did this "fun" little experiment in high school.  We placed a bet on just how bad it is and when I ran a swab and incubated it, you would not believe the degree of gram-positive bacteria that I found. 


Update:
Ok nvm I managed to email these from my phone to myself and uploaded the pics.  The purple objects are the gram-positive bacteria in the images.  Sorr it's not better quality.  All I had on me was my phone camera at the time.  (This is why I don't carry cash...ewww)

Each of the blue blobs in the above is an individual HIV particle or "virion" and it measures about 100nm - that's about 1/10,000th of a millimetre.

Could we please have some bars so that we know how large these organisms are.

Yes, sorry, they were not present on the original images.

Has anyone been tested/treated for chronic bacterial or viral infections?I have just received blood tests showing I have a very high immune response to the bacterium chlamydia Pneumoniae and also Coxsackie virus, both of which are known to precipitate a whole host of nasties including MS and peripheral Neuropathy.Im going to dig out some papers to share. bestAlex

Sounds like they've done CFTs (complement fixation tests) on a sample of your blood. This sort of immune reactivity is quite common. C. pneumoniae is a frequent and under-diagnosed caused on atypical chest infections, especially in young people, and Coxsackie viruses are far from rare.

CFTs measure the antibody levels in a blood specimen and merely reflect what you have encountered recently. Even re-encountering something to which you already have mounted a response will provoke a high reading owing to the mobilisation of immune "memory". I wouldn't worry, unless you have other, unexplained symptoms that you have not mentioned.
