“Get me more, mummy!” demands one youngster bacterium, pointing to the drops of antibiotic reaching the colony headquarters.

Come on! FOR REAL?

Sadly very true and it is not even that infrequent either! I only became aware of this after reading about a study, where researchers in HMS, led by Dr. George M. Church, collected soil samples in an experiment, attempting to search for more bio-diversity and were stunned to see that as they added antibiotics to these bacterial cultures, the bacteria didn’t seem to mind at all!

Unlike human beings, bacteria tend to like sharing. The more they share their strategic defenses, the more prosperity they end up living in. Again, to our dismay, such fear was translated into reality, as this has already extended to the pathogenic minorities of the bacterial world in a new study, published in January in the International Journal of Tuberculosis and Lung Disease. Scientists, in China, have stumbled upon a strain of tuberculosis-causing bacteria, called Mycobacterium tuberculosis, INCAPABLE of growing adequately in the absence of rifampicin. This is as ominous as such news can get.

This strain was discovered as physicians attempted to treat a TB-infected patient with a regimen which included rifampicin. Unexpectedly, his condition worsened and only upon the removal of rifampicin did he start feeling better, until eventually full recovery. Already, reports of multidrug-resistant TB “MDR” have been around for some time. Normally, the treatment course includes more than 1 drug to be able to effectively kill the bacteria. Apparently, the bacteria have found a way to get around that!

We can only wonder: which antibiotic is next?

So you drive over to the lab to have your blood work? In the near future, that would totally be ‘old-school’. Even if you so much as consider making that journey, you have GOT to be tempted to please think again! Time has been proven, repeatedly, to be of the essence, both for the sake of the diagnosis & treatment and the patient’s quality of life. For instance, imagine the convenience it will provide for an HIV-infected patient, who is what a lab technician would probably call a regular customer, due to the regular follow-up tests needed to monitor the development and treatment. Through a $10 piece of hardware connected to your cell phone, you will have your medical test results ready on the go. All you’d have to do is insert a slide containing a drop or two of your blood and leave the rest of the work up to the chip, as demonstrated on a prototype. I will even bet that, those who choose not to use it, would be charged extra for lab work!!!

The Ozcan Research Group at UCLA will already begin their field tests in Africa concerning the new cell phone/microscope gadget. I had to see to believe. Aside from all the engineering & technological aspects, which I am sure are quite many, if this were to be actually implicated worldwide, the possibilities of its application are endless, including, but not necessarily limited to, pretty much all of the blood-borne diseases. For instance, malaria, which is fairly common in many African countries, can be instantly diagnosed. The hospital would get the patient’s blood picture, through the cellular networks for analysis by physicians and there you have it.
