Researchers in Germany reported yesterday that they had altered the DNA of a disease-causing bacterium to enable it to infect a species it cannot normally sicken -- a double-edged advance that experts said could deepen scientists' understanding of human diseases but could also speed the development...

Wherever humans go, microorganisms follow--and that includes space. Bacteria and other microbes living onboard spaceships may not only cause health problems for the crew, but also cause the spaceship itself to malfunction.

Researchers at Brigham and Women&#39;s Hospital and Beth Israel Deaconess Medical Center have found a faulty genetic signaling process that may help explain how Crohn&#39;s disease develops.

A new study suggests the reason for the association may be that antibiotics destroy not only disease-causing microbes, but also those that are helpful to the developing immune system.

A common infection that causes diarrhea may be to blame for the nearly doubled incidence of a certain kind of colitis, U.S. researchers said on Monday.

NEW YORK  - Infants who are regularly exposed to farm animals appear to be less likely than others to develop inflammatory bowel disease in childhood, according to the findings of a German study published in the journal Pediatrics.

Bacteria that cause a troublesome and sometimes fatal type of diarrhea in hospital patients can be found in and on the bodies of people who have no symptoms at all, U.S. researchers reported on Friday.

This week, researchers report new findings that elucidate the role of NOD2, a key molecular player in Crohn&#39;s Disease, in the cellular signaling pathways that control inflammatory responses.

A genetically engineered antibody that blocks an immune system molecule has produced promising results in its first use against Crohn&#39;s disease, researchers report.

Patients with Crohn&#39;s disease, a chronic inflammatory bowel disease, who do not respond to conventional treatment, may get symptom relief by swallowing parasite eggs.

Researchers on a safari for microbes have found that human skin is populated by a veritable menagerie of bacteria -- 182 species -- some apparently living there permanently and others just dropping by for a visit.
