Women lead in bacteria, hands down, study says

Updated Mon. Nov. 3 2008 9:50 PM ET

The Associated Press

WASHINGTON -- Wash your hands, folks, especially you ladies.

A new study found that women have a greater variety of bacteria on their hands than men do.

And everybody has more types of bacteria than the researchers expected to find.

"One thing that really is astonishing is the variability between individuals, and also between hands on the same individual," said University of Colorado biochemistry assistant professor Rob Knight, a co-author of the paper.

"The sheer number of bacteria species detected on the hands of the study participants was a big surprise, and so was the greater diversity of bacteria we found on the hands of women," added lead researcher Noah Fierer, an assistant professor in Colorado's department of ecology and evolutionary biology.

The researchers aren't sure why women harboured a greater variety of bacteria than men, but Fierer suggested it may have to do with the acidity of the skin. Knight said men generally have more acidic skin than women.

Other possibilities are differences in sweat and oil gland production between men and women, the frequency of moisturizer or cosmetics applications, skin thickness or hormone production, he said.

Women also may have more bacteria living under the surface of the skin where they are not accessible to washing, Knight added.

Asked if guys should worry about holding hands with girls, Knight said: "I guess it depends on which girl."

He stressed that "the vast majority of the bacteria we have on our body are either harmless or beneficial ... the pathogens are a small minority."

The researchers took samples from the palms of 51 college students -- that's 102 hands -- and tested the samples using a new, highly detailed system for detecting bacteria DNA.

They identified 4,742 species of bacteria overall, only five of which were on every hand, they report on Monday's online edition of Proceedings of the National Academy of Sciences.

The average hand harboured 150 species of bacteria.

Not only did individuals have few types of bacteria in common, the left and right hands of the same individual shared only about 17 per cent of the same bacteria types, the researchers found.

The differences between dominant and non-dominant hands were probably due to environmental conditions like oil production, salinity, moisture or variable environmental surfaces touched by either hand of an individual, Fierer said.

Knight said the researchers hope to repeat the experiment in other countries where different hands are assigned specific tasks.

While the researchers stressed the importance of regular hand washing, they also noted that washing did not eliminate bacteria.

"Either the bacterial colonies rapidly re-establish after hand washing, or washing (as practised by the students included in this study) does not remove the majority of bacteria taxa found on the skin surface," the researchers said in their report.

While the tests could determine how many different types of bacteria were present, they could not count the total amount of bacteria on each hand.

The research was funded primarily by the National Institutes of Health and the National Science Foundation.

That germ fear-mongering crap is pissing me off.
Let people get dirty, expose them to stuff, it makes them stronger. Constant disinfecting just makes your immune system weaker.

I do my best to stay dirty all the time. Only negative side effect are the occasional red hand print on my face.

Exactly!
I see people at work that open the washroom door with their hand wrapped on their shirt, a paper towel, whatever..
.. and those are the ones that are always sick with a flu or something.. lol

The poor girl in the first pic looks like her back is sore the way she is holding that tree.... Perhaps I could give her a hand with that heavy load she is carrying... ;)

Lying on her back would take that weight off also..... ;)

Reminds me of an old ad for the 224 Orange. Imagine a pic of a nice pair of boobies with the caption

"Given the choice always go large".

Was in an old issue of Dirt - cannot find it right now. *sigh*

Anyone got Gooch's old quote? Went something like: "this powder is too deep, those boobs are too big and this blowjob is taking too long"

You realize microbiology is often a huge part in modern evolutionary studies right? Either way, its moot because they used students. Students are fucking gross anyway.

This powder is too deep, this beer is too cold, this cigar is too smooth, this blowjob is taking too long.

I think that was it.
