Potentially deadly infection may be linked to frequent cow exposure

19.02.2010
A common bacteria found in many healthy adult females that can cause life-threatening infections when passed to newborns could be introduced to some women through frequent contact with cows, according to a research team led by a Michigan State University pediatrician.

The recently published findings that Group B streptococcus could be a zoonotic disease - transmitted between different species - may have significant public health implications, said Dele Davies, chairperson of MSU's Department of Pediatrics and Human Development.

GBS, first recognized as a bacterium that leads to infections in the breasts of cows, is now found in up to 36 percent of pregnant women in their digestive or genital tracts. When passed to newborns during pregnancy, the infection can be severe - leading to death - though not all infants become sick.

While GBS affects only 1 in every 2,000 babies, and there are prenatal tests to identify it, Davies said understanding how women are infected could greatly reduce transmission rates.

Efforts have been made to understand the risk factors that lead to transmission from mothers to babies, but it hasn't been established how mothers originally acquire it, Davies said.

As part of the study, Davies, fellow MSU professor Shannon Manning and a team of MSU researchers conducted a cross-sectional cohort study of 68 families and their livestock, collecting and comparing stool specimens. Increased frequency of cattle exposure was significantly associated with human infection, and one couple shared the same GBS strains as their cows, suggesting zoonotic transmission.

"Our study suggests that for at least some women, there is an association between increased exposure to cattle and colonization of the bacteria," he said. "Though GBS human infection has long been suspected as originating from cows, several investigators have suggested that ongoing interspecies transmission is unlikely.

"The possibility of ongoing transmission between humans and their livestock has not been systematically examined, and future studies are needed."

The research was published in PLoS One, a journal published by the nonprofit Public Library of Science, at http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0008795. Co-collaborators included researchers at MSU's National Food Safety Toxicology Center and the Bureau of Laboratories at the Michigan Department of Community Health.

Michigan State University has been advancing knowledge and transforming lives through innovative teaching, research and outreach for more than 150 years. MSU is known internationally as a major public university with global reach and extraordinary impact. Its 17 degree-granting colleges attract scholars worldwide who are interested in combining education with practical problem solving.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
