What is a rapid and inexpensive way to identify
from plated media?
Rapid indole is a good way to start, however, there are 52 species of gram-negative bacilli that grow on MacConkey, are indole-positive, and ferment lactose. The more common ones include
Citrobacter freundii, C. sedlakii, C. braakii, C. koserii, C. amalonaticus, C. youngae, Aeromonas hydrophila and Serratia odorifera.
Therefore, another rapid test is needed, such as glucuronidase. This test will give a positive result for most all
E. coli O157
Hardy ColiScreen combines both a rapid indole and glucuronidase test into one tube. Results are obtained from one to four hours.

The term well heeled is used to refer to someone both well off financially or well dressed. Its origins actually lie in the blood-lust sport of cockfighting. If a bird was well heeled, it was in possession of good spurs – sharp and dangerous metal ‘heels’ attached to the back of a cock’s foot.

Case History #9
from Brent Barrett
A Puzzling Worm
hospital submitted a worm to the state public health laboratory for identification. It was removed during a colonoscopy from a 31 year old male. Further patient medical history was not provided.
Macroscopic observation showed a worm that measured about 20mm long and one end appeared to be broken off suggesting a longer overall length.

. . . an increasing problem
A recent study tracked
drug susceptibility over a 12 year period and found a significant increase in resistance to all drugs tested except for tetracycline.
Over 3.1 million susceptibility test reports from 1998 to 2010 were analyzed at the George Washington University in Washington DC.
Resistance to imipenem (a subgroup of carbapenem antibiotics) first appeared in the database in 2004 and rose gradually to 4.3% by the end of 2010.
The largest increases in antimicrobial drug resistance from 1998 to 2010 were observed for aztreonam (7.7% to 22.2%), ceftazidime (5.5% to 17.2%), and ciprofloxacin (5.5% to 16.8%). However, the researchers found smaller changes in resistance to tetracycline (14.2% to 16.7%) and amikacin (0.7% to 4.5%).
“Increasing antimicrobial drug resistance, including carbapenem-resistant
(CRKP), accounts for substantial increases in illness and death and stresses health care resources,” the researchers write. “Few antimicrobial therapy options exist for infections caused by CRKP.”
In the current study, CRKP prevalence was higher for intensive care units than for other hospital units (6.3% vs 3.8%, respectively).
Newer-generation tetracyclines “may prove useful in the treatment of CRKP-related infections because of their improved tissue penetration, antimicrobial activity, and decreased propensity to develop antimicrobial drug resistance compared with their older counterparts,” the researchers write.
This emerging problem of increased resistance combined with a lack of novel antimicrobials in development present a major threat to public health and warrant due diligence in future surveillance efforts.

Warning to green shoppers…
Beware of the
Reusable Grocery Bag!
Recently, many municipalities have implemented bans or imposed taxes upon plastic or paper grocery bags on environmental grounds, in an effort to encourage shoppers to bring their own reusable bags.
San Francisco County was the first major U.S. jurisdiction to enact such a regulation, implementing a ban in 2007. There is evidence, however, that reusable grocery bags, a common substitute for plastic bags, contain potentially harmful bacteria.
A recent study at the University of Pennsylvania and George Mason University examined emergency room admissions related to these bacteria in the wake of the San Francisco ban. They found that ER visits spiked when the ban went into effect. Relative to other counties, ER admissions increase by at least one fourth, and deaths exhibit a similar increase.
“We were finding that deaths, for example, from foodborne illness or intestinal infections goes up from anywhere between 50% and 100%, so a doubling in some instances” according to the researcher, Jonathan Klick. He also says, “More people are showing up in the emergency rooms, and it turns out they have

No coughing or sneezing required
Flu virus spreads
up to 6 feet
he influenza virus can travel and be infectious within a six foot radius of a patient’s head according to a new study from the Wake Forest School of Medicine in North Carolina. Most alarming about this study is that the patients tested spread the virus even when not coughing or sneezing; they were simply breathing.
Investigators enrolled 94 patients with influenza-like illness in the study. They obtained patient history and took nasopharyngeal swab specimens. The researchers then collected quantitative impaction air samples 1 foot or less, 3 feet, and 6 feet from the patient’s head during routine care. Rapid test and polymerase chain reaction were used to detect influenza virus.
Also discovered was that some influenza patients (19%) are “super-emitters” shedding up to 32 times more viral particles than other patients. The size of the particle droplets were found to be much smaller at 6 feet than at 1 foot.
The N95 rated face masks
are effective in blocking 95% of particles greater than 0.3 microns in size, and can be useful in protecting health care workers as well as friends and family of the afflicted patients.
Which face looks happier?
The right one? But how can that be when both faces are the same, except for being the mirror image of each other?

Should clinical labs
hire more MLT’s?
Currently the management of clinical laboratories find that they must continually cut costs and increase efficiency.
Some labs do this by utilizing more and more the services of Medical Laboratory Technicians (MLT), rather than hiring the more highly paid and extensively trained Clinical Laboratory Scientists (CLS). Is this a trend that should continue?
What did our readers say? …
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?
