Legionella found in hospital faucets

faucet

A recent study conducted at Johns Hopkins Hospital in Baltimore found high and persistant counts of theLegionellabacillus in patient room faucets.

Strangely, it was more frequently found, and the counts were much higher, in the newer electronic hands-free faucets that were designed to conserve water and prevent cross contamination. The exact cause for the higher counts over the conventional faucets is not known, although the complex valve mechanisms may provide inaccessible areas for the organisms to thrive.

The study also exposed a weakness in the water treatment system, which allowedLegionellato thrive in the faucet valves even with counts up to 3,000 cfu/ml.

Many hospitals periodically flush their water systems with chlorine dioxide or use hyperchlorination techniques in an effort to controlLegionella.Pseudomonas aeruginosa,Stenotrophomonas maltophilia,
andChryseobacteriumandAspergillusspecies can also colonize hospital water systems.

The Johns Hopkins Hospital is currently in the process of removing all electronic faucets and is replacing them with conventional models.

Hardy Diagnostics providesBCYE Agar, which is used to isolate and detectLegionellaspp., in addition toseveral rapid test kits.

Phraseology

“The Real McCoy”

Real McCoy


Ever wonder where the phrase “The Real McCoy” came from? It actually came from a brand of Scottish whiskey. In 1856
, the G. Mackay and Co. of Edinburgh, Scotland, began to use “The Real Mackay” as their advertising slogan.

When it crossed the Atlantic the spelling shifted to become

“McCoy”in America. This phrase eventually was used to indicate that something is genuine and authentic.

In 1969, the Coca Cola Company seized the idea and used “It’s the real thing” in their marketing campaigns.

Think about it…

The Thinker

  • Why are the songs that get stuck in my head ALWAYS little kid songs?
  • Why do they sterilize the needles for lethal injections?
  • Why is there a pair of panties but just one bra?
  • How can someone be dirt poor, and another be filthy rich?
  • Does pushing the elevator button more than once make it arrive faster? No? Then why do we do it?

Who works the most?

Workers

It turns out that Mexicans work longer days than anyone else in developed nations, devoting 10 hours to paid and unpaid work, such as cleaning or cooking at home.

Belgians work the least, at 7 hours, compared with an average of 8 hours a day. American workers ranked in the middle at about 8 hours and 20 minutes.

Most unpaid work is housework. Mexicans do the most, at more than 3 hours per day, and Koreans the least, at 1 hour and 19 minutes.

Much of this time is spent cooking. Americans spend the least time cooking each day (30 minutes) and Turks the most (74 minutes). Most people spend around 50 minutes a day cooking.

Shopping also makes up a big part of unpaid work. Most people spend 23 minutes a day shopping, with the French spending the most (32 minutes) and the Koreans the least (13 minutes).

Case histories from Dr. Joe…

Can you

name that pathogen?

Aerococcus

CASE HISTORY, No. 1

A 76 year old male with a history of dementia and bipolar disorder was transferred from a nursing home to our acute care hospital due to decreased urinary flow and confusion. The patient was admitted to the ICU for acute renal failure, a Foley catheter was placed and IV fluids given. A catheter urine was sent for culture, followed by two sets of blood cultures. The patient was stabilized and transferred to a medical floor the following day.

The next morning, the urine culture grew >100,000 cfu/ml of alpha looking colonies that were catalase (-), LAP (+), and PYR (+). A preliminary report of possibleEnterococcuswas issued.  Positive blood culture bottles, however, showed gram-positive cocci in clusters.

Aerococcus stain

Subcultured colonies were also catalase (-), LAP (+), and PYR (+). Additional biochemical testing indicated the organism was Bile Esculin and Salt Broth (+). Testing on API 20 Strep produced an identification ofStreptococcus acidominimus(95.9%), which was thought to be incorrect. Molecular gene sequencing confirmed the organism indentification that was suggested by phenotypic test results.

Yersin

Alexandre Yersin

1863 ~ 1943

The discoverer of the

plague bacillus

Alexandre Yersin was a Swiss bacteriologist who worked as a young researcher with both Robert Koch and Luis Pasteur in the late 1800’s. He was born in Switzerland in 1863 to a family originally from France. After studying medicine there, he moved to Germany and then Paris. He studied tuberculosis in Robert Koch’s lab where he received his doctorate.

He then joined Pasteur’s lab and became the co-discoverer of the diphtheria toxin along with Emile Roux.

In 1894 he was sent by the Pasteur Institute and the French government to study the bubonic plague in Hong Kong. It was there, along with Kitasato Shibasaburô, that he made the important discovery for which he is most famous.

in Hong Kong, 1894.

He not only isolated the bacillus that causes the bubonic plague, but he proved that the transmission to humans involved rodents. It wasn’t until 1898 that Simond proved that the agent that transferred the plague from the rat to humans was the flea.

And thus the mystery of the cause of plague, the disease that wiped out from 30 to 60% of Europe’s population in the 1300’s, was finally solved. The bacillus,Yersinia pestis, was named in his honor.

After this discovery, he spent most of the remainder of his life in Viet Nam (as he is seen in the top photo above), where he founded a medical school and was instrumental in growing quinine trees for the treatment of malaria. It was in Nha Trang that he died during World War II.  He is well remembered in Viet Nam, with a memorial and museum that was built in his honor.

hospital infections

Should hospitals be required by law to publicly report infection rates, surgical complications, and medication errors?

Note: Currently, hospital acquired infection (HAI) rates are required to be publicly reported in 26 states. In addition, 12 states also have laws requiring the screening and/or reporting of hospital acquired MRSA infections.

“There has never been a protracted war from which a country has benefited.”

“If ignorant both of your enemy and yourself, you are certain to be in peril.”

“Regard your soldiers as your children, and they will follow you into the deepest valleys; look on them as your own beloved sons, and they will stand by you even unto death.”

“The general who wins the battle makes many calculations in his temple before the battle is fought. The general who loses makes but few calculations beforehand.”

“Know thy self, know thy enemy. A thousand battles, a thousand victories.”

“Pretend inferiority and encourage his arrogance.”

“All warfare is based on deception.”

“To fight and conquer in all our battles is not supreme excellence; supreme excellence consists in breaking the enemy’s resistance without fighting.”

“Avoid what is strong and strike at what is weak.”

“The mark of a great general is that he fights on his own terms or not at all.”
