The evolutionary success of wood- and litter-feeding termites is based on their ability to efficiently digest lignocellulose although it is highly recalcitrant to enzymatic attack and has a low nitrogen content (Abe et al., 2000). An intimate symbiosis with archaeal, bacterial, and eukaryotic gut...
The virus's ability to replicate is closely related to the weather. At 70 degrees Fahrenheit, it takes the virus three weeks to multiply to a point where it is transferable to another animal. At 80 degrees Fahrenheit, the time is shortened to two weeks, and during spells with temperatures ...
These results indicated along with respiratory systems, that the digestive system is a potential route for 2019-nCov infection. In this way, the ACE2 has a specific function in intestinal tract, regulating intestinal amino acid homeostasis, expression of antimicrobial peptides, and the ecology of ...
But the new research goes a step further—it specifically identifies maternal microbiota as source of newborn immunity. It further suggests that the intestinal microbiota could offerimmune protectioneven when mothers have had no prior encounters with an infection that allows them to build and pass on...
The study, which combined experimental observations with mathematical modeling, showed that the flow of liquid can have two significant effects onmicrobes: "It quenches the ability of microbes to chase food," Stocker says, "and it helps microbes find surfaces." ...
A number of Lactobacillus, Propionibacter- ium, and Bifidobacterium strains have the ability to produce these bioactive fatty acids, and in addition, Roseburia spp. has been identified among the most active producers in the gut (Devillard et al, 2007). However, there are indications that a ...
When the team knocked out the gene for CNM in strains where it s normally present, the bacteria were unable to invade heart tissue. Without CNM, the bacteria simply couldn t gain a foothold; their ability to adhere was about one-tenth of what it was with CNM. ...
These concepts emphasize the intimate relationship between the gut microbiota and its host, as well as the influence of host genetics on the gut microbiota composition and the ability of the gut microbiota to enhance host defense against pathogens. Rapid shifts in the gut microbiota, distinct from...
It is a challenge for the gut to maintain stability of the microbiota without inducing inflammation, while maintaining the ability to clear intestinal infections. This is called intestinal homeostasis. Perturbations in homeostasis are the basis of various diseases such as obesity, diabetes and ...
While some patients experience acute rejection within the first year after transplantation, others retain their grafts long-term despite similar immunosuppression [6, 7], and a small subset spontaneously develops operational tolerance, the ability to maintain allografts without rejection after withdrawal of...
