The bacteria that cause periodontitis, a disease affecting the tissues surrounding the teeth, seems to play a part also in the onset of pancreatic cancer.

Amoebae, single-celled organisms common in soil, water and grade-school science classrooms, may play a key role in the survival and spread of deadly plague bacteria. New research shows that plague bacteria, Yersinia pestis, not only survive, but thrive and replicate once ingested by an amoeba. The discovery could help scientists understand why plague outbreaks can smolder, stay dormant for years, and re-emerge with a vengeance.

Research, published Monday in the journal Nature, reports DNA analysis has unmasked Salmonella enterica bacteria as the cause of a 16th century epidemic that affected large parts of Mexico and wiped out an estimated 800,000 people in the Aztec Empire. The study, by Germany’s Max Plankc Institute for the Science of Human History, discovered the introduction of Salmonella in the Americas; which is believed to have been brought to the continent by Europeans. The identification of S. enterica bacteria, which causes typhoid, supports the theory that typhoid fever was...
|Surfers three times more likely to have antibiotic-resistant bacteria in guts|

Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed.

Biochemists report a bacterial, iron-only nitrogenase pathway for methane formation.
|Genetic Variation between Pathogen Strains Contributes to Diverse Patient Immune Responses|

Individuals have wide-ranging physiological responses to the same species of pathogen. Researchers have demonstrated that different strains of a given bacterial species can elicit unique adaptive immune responses in the same individual, suggesting that variation between bacterial strains can explain heterogeneity in patient infection vulnerability. Diverse patient responses to the same species of pathogen have [...]
