  • thrive
  • It was suggested that bacteria thrive in the Mariana Trench, which with a depth of up to 11 kilometres is the deepest known part of the oceans. (wikipedia.org)
  • nutrients
  • Triatomine vectors have only one host and therefore must establish a relationship with bacteria to enable them to obtain the nutrients required to maintain themselves. (wikipedia.org)
  • microbiota
  • The team discovered that systemic sclerosis patients' microbiomes are enriched by inflammatory bacteria while protective bacteria were reduced, with systemic sclerosis patients exhibiting a microbiota flora similar to patients with Crohn's disease (a type of inflammatory bowel disease, characterized by chronic inflammation at the digestive tract). (sclerodermanews.com)
  • Researchers found an enrichment of bacteria species Erwinia and Trabulsiella in systemic sclerosis patients with the most severe symptoms, suggesting that "not only are there differences in the microbiota composition between systemic sclerosis patients and healthy controls, but these differences may contribute to clinical symptoms," Dr. Volkmann explained .

  • This method can be used to recover specific indicator bacteria. (wikipedia.org)
  • Polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) are gene sequence-based methods currently being used to detect specific strains of indicator bacteria. (wikipedia.org)
  • evolutionary
  • However, the distribution of bio-luminescent bacteria is uneven, which suggests evolutionary adaptations. (wikipedia.org)
  • They did not find that the rhizobial bacteria studied had any evolutionary advantage with their host but did find great genetic variation among the populations of rhizobial bacteria studied. (wikipedia.org)
  • harmless
  • Even though bacteria have a bad reputation in our society, most types are completely harmless to humans, or even helpful! (google.com)
  • The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, though many are beneficial particularly in the gut flora. (wikipedia.org)
  • Although most bacteria are harmless or often beneficial, some are pathogenic, with the number of species estimated as fewer than 100 that are seen to cause infectious diseases in humans. (wikipedia.org)
  • pneumonia
  • Finally, some of these bacteria can cause a specific type of pneumonia referred to as atypical pneumonia. (wikipedia.org)
  • That is not to say that atypical pneumonia is strictly caused by atypical bacteria, for this disease can also have a fungal, protozoan or viral cause. (wikipedia.org)
  • opportunistic
  • While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic. (wikipedia.org)
  • Intestinal
  • In mice, these bacteria grow primarily in the terminal ileum in close proximity to the intestinal epithelium where they are thought to help induce T helper 17 cell responses. (wikipedia.org)
