How can I detect
E. coli O157
all on one one stool plate?
Hardy’s stool biplate can isolate all three. The biplate consists of CIN Agar on one side and MacConkey with Sorbitol on the other.
CIN Agar can be used to selectively isolate
(the colonies will be large with a red center). MacConkey with Sorbitol is a selective and differential media for
O157 (the colonies will be colorless).
This biplate is a good way to effectively screen for all three of these enteric pathogens.

a New Leaf”
This one has nothing to do with plants! In this case, “Leaf” is a semi-archaic term for a page. To turn over a new leaf, therefore, is to turn to a new page in a book.
In this phrase, the book is most likely to be a journal or diary, where the new blank page gives you a fresh chance to fulfill your good intentions.
The beginning of 2013 is a good time to write something new and fresh on that leaf which is your life’s story.

Think about it…
* Why is it that people say they ‘slept like a baby’ when babies wake
up like every two hours?
* If a deaf person has to go to court, is it still called a hearing?
* Why are you IN a movie, but you’re ON TV?
* Why do people pay to go up tall buildings and then put money in
binoculars to look at things on the ground?
* Why do doctors leave the room while you change? They’re going to see you naked anyway.
* Why do toasters always have a setting that burns the toast to a
horrible crisp, which no decent human being would eat?

Case History #8
from Dr. Tortora
A SORE THROAT
young man came to the emergency room complaining of a fever and rash on his abdomen and arms. He had a history of a sore throat. His CBC showed a high white count. A chest X-ray was done and CT scan showed inflammation of the jugular vein of his neck. This resulted in a diagnosis of Lemierre’s Disease. As expected, his blood cultures grew out
and he was put on appropriate antimicrobial therapy for this anaerobe.

But wait! His symptoms did not resolve. A second set of blood cultures revealed growth of a gram positive rod resembling

Antibiotic use cut by 64% !
effective against respiratory tract infections
n patients with increased frequency of respiratory tract infections, supplementation with 4000 IU of vitamin D3 for one year reduced symptoms and the need for antibiotics, according to a recent study from Sweden.
At the Karolinska University Hospital, 140 participants were assigned to receive 4000 IU vitamin D3 or placebo daily for one year. Participants included patients with antibody deficiency (selective immunoglobulin A deficiency, immunoglobulin G subclass deficiency, common variable immunodeficiency) or with more than four bacterial respiratory tract infections per year. All participants had respiratory symptoms for at least 42 days before randomization.
The main study outcome was an infectious score calculated from five clinical characteristics that the patients recorded in a daily diary: respiratory symptoms, ear symptoms, sinus symptoms, malaise, and antibiotic use.
Compared with the placebo group, the vitamin D group had a significantly lower overall infectious score (202 points vs 249 points).
In the vitamin D group, symptoms of respiratory tract infection decreased by nearly 25%. The odds of taking antibiotics during the study period decreased by 63.5% in the vitamin D group, and the absolute number of days on antibiotics decreased by 50%
(from 33 days in the placebo group to 16 days in the vitamin D group).
All patients tolerated vitamin D treatment well, with no serious adverse effects.

Dog Outperforms Microbiologists
an a dog be more efficient at detecting
than a hospital microbiologist? And with a faster turn around time?
A recent study published in the
British Medical Journal
showed that a dog trained to sniff out
could do so with a sensitivity of 100% and a specificity of 94%.
Cliff, a two year old beagle from Amsterdam pictured above, has proven himself to be a valuable asset in combating
, the most common cause of hospital acquired diarrhea.
After proving a 100% sensitivity with specimens, Cliff was then taken to two
wards to conduct further detection tests in a live environment. The dog managed to correctly identify 25 of 30 cases (83 percent sensitivity) and 265 of 270 negative controls (98 percent specificity).
Researchers added that the
was efficient and quick, managing to screen a complete hospital ward for the presence of patients infected with
in fewer than 10 minutes.
When Cliff finds a patient with a
infection, he simply sits down by the patient’s bed and awaits his reward in the form of a biscuit.
A dog’s sense of smell is hundreds of times more sensitive than ours, which is why dogs have been used successfully for detecting many disease states, including cancer.

sniffing dog, who puts microbiologists to shame!

Should stores be open on Thanksgiving Day?
For the first time, many stores opened their doors to bargain hunters on Thanksgiving Day, thus shattering the tradition of waiting until “Black Friday” to accommodate the hoards of holiday shoppers.
what your fellow MicroBytes readers thought about this. The results were very lopsided!
Should medical device companies have to
pay a 2.3% excise tax?
tarting on January 1, 2013, all medical device manufacturers will be required to pay a 2.3% tax on all sales. The new tax, required by the Affordable Care Act (“Obamacare”), is levied on medical devices sold domestically.
Medical devices range from simple tongue depressors and bedpans to complex pacemakers and laser surgical devices. In addition, medical devices include
diagnostic products, such as general purpose lab equipment, reagents, and test kits,
including culture media.
This tax is on all sales (top line) regardless of whether the company made a profit or not (bottom line). Medical device manufacturers are the only industry required to pay the 2.3% tax.
The tax is expected to bring in $20 billion to the federal government over the next 10 years. The House of Representatives voted to kill the tax, but the Senate is currently in favor of keeping it.
Will the new tax eliminate jobs, stifle innovation, and make American manufacturers less competitive; or does the new tax represent a good way to help pay down the enormous federal deficit?
Are you in favor of keeping the tax?
