"Stomach Bug May Ward Off Asthma" July 16, 2008
Helicobacter pylori Colonization Is Inversely Associated with Childhood Asthma
Yu Chen, Martin J. Blaser
"...scientists analyzed data from more than 7,000 participants in a national health and nutrition survey. They found that children between the ages of three and 13 are less than half as likely to have asthma if they carry H. pylori. They also had half the incidence of hay fever and other allergies. The results appear online in the July 15th issue of The Journal of Infectious Diseases."

"Stomach Germ May Protect Against Asthma" July 15, 2008
Helicobacter pylori Colonization Is Inversely Associated with Childhood Asthma

Yu Chen, Martin J. Blaser
"A stomach bacterium called Helicobacter pylori may reduce a child's risk of developing asthma by as much as 50 percent, a new study suggests.  H. pylori has been present in the human stomach probably since humans were humans. However, the germ began disappearing over the course of the 20th century with the introduction of antibiotics and cleaner water and homes, perhaps making children more susceptible to asthma, the study authors suggested."

"Internal Bacterial Imbalance Leads to Asthma" July 15, 2008
Helicobacter pylori Colonization Is Inversely Associated with Childhood Asthma
Yu Chen, Martin J. Blaser
"In a study published yesterday in the Journal of Infectious Diseases, researchers showed that Heliobacter pylori, an intestinal microbe that co-evolved with humans, appears to protect children from asthma.  Asthma rates have nearly doubled in the United States since 1970, and are swelling in the developing world. Underlying the rise is a constellation of causes -- and one of these may be the loss of H. pylori, a vanishing member of the rich bacterial ecosystems in our stomachs."

"Peruvian Mummies' Lice Came from Africa" February 7, 2008
Molecular Identification of Lice from Pre-Columbian Mummies

When humans migrated out of Africa 100,000 years ago, they were likely carrying stowaways. Scientists who've tested head lice taken from Peruvian mummies found the strains of these little parasites were nearly identical to those that were irritating our ancestors in Africa.

Molecular Identification of Lice from Pre-Columbian Mummies

[In a new paper for the JID, scientists] establish that lice had accompanied their human hosts in the original peopling of the Americas, probably as early as 15,000 years ago. The DNA matched that of the most common type of louse known to exist worldwide now and also before Europeans colonized the New World.

Molecular Identification of Lice from Pre-Columbian Mummies

Head lice taken from 1,000-year-old mummies in Peru support the idea that the little creatures accompanied humans on their first migration out of Africa, 100,000 years ago, researchers reported on Wednesday.
