"'Super' bacteria live on sheets, fingernails-study", Reuters, June 6,
2005,

The mutated, drug-resistant "superbugs" that cause an increasing number
of hospital infections and deaths can live for weeks on bed linens,
computer keyboard covers and under acrylic fingernails, U.S.
researchers reported on Monday.

The study supports other research that shows super-strict hygiene is
needed to battle the bacteria, some of which are now nearly impossible
to kill even with the strongest antibiotics.

A team at sanitation-services company Ecolab Inc. dabbed
methicillin-resistant Staphylococcus aureus onto samples of bed linen,
keyboard covers and acrylic fingernails.

MRSA could be detected eight weeks later on acrylic fingernails, six
weeks later on computer keyboard covers and five days later on bed
linens, the researchers told a meeting in Atlanta of the American
Society for Microbiology.

"The results of this study clearly demonstrate the need for frequent
hand washing and environmental disinfection in health care settings,"
said researcher Kris Owens of Mendota Heights, Minnesota-based Ecolab.

Staphylococcus aureus is usually harmless and very common, found on
skin or in the noses of about 30 percent of people. It can cause
stubborn problems such as rashes and boils and an infection is often
mistaken for a spider bite.

In hospitals, MRSA can cause serious and sometimes deadly infections,
including necrotizing fasciitis or "flesh-eating" disease. It resists
almost everything but an intravenous antibiotic called vancomycin.

A study at Northwestern Memorial Hospital in Chicago, published in
April, found that computer keyboards can contaminate the fingers, bare
or gloved, of a nurse or doctor, who could then transfer bacteria to
patients.

Other studies have shown that, despite the importance of hand-washing,
doctors, nurses and other health care workers often fail to do so or do
not wash thoroughly.

patients.

Did these people speculate how a bacterium on a computer keyboard could
pass thorogh a glove to contaminate a user?

Did these people speculate on how many bacteria it took to infect a
person and cause a disease? Is it one bacteria, a million bacteria, or
a zillion bacteria that is needed to infect a person and start an
infection?

I think the sentence means that gloved fingers could be contaminated
on the glove.
