| insight into the genome of staphylococcus xylosus, a ubiquitous species well adapted to meat products. | staphylococcus xylosus belongs to the vast group of coagulase-negative staphylococci. it is frequently isolated from meat products, either fermented or salted and dried, and is commonly used as starter cultures in sausage manufacturing. analysis of the s. xylosus genome together with expression in situ in a meat model revealed that this bacterium is well adapted to meat substrates, being able to use diverse substrates as sources of carbon and energy and different sources of nitrogen. it is well- ... | 2017 | 28850086 |
| severe dermatitis associated with spontaneous staphylococcus xylosus infection in rag(-/-)tpl2(-/-) mice. | staphylococcus xylosus is a commensal bacterium found on the skin and mucosal surfaces of spf mice. s. xylosus is rarely pathogenic, most often causing skin lesions and dermatitis in immunocompromised mice, particularly those with impaired nadph oxidase function. here we report spontaneous infection with s. xylosus in rag1-/-tpl2-/- mice. infection was characterized by the presence of alopecia, crusts, and scaly skin. s. xylosus was detected in the feces, skin, lymph nodes, and lungs of rag1-/-t ... | 2017 | 28830581 |
| purification and characterization of trypsin produced by gut bacteria from anticarsia gemmatalis. | purification of active trypsin in the digestive process of insects is essential for the development of potent protease inhibitors (pis) as an emerging pest control technology and research into insect adaptations to dietary pis. an important aspect is the presence of proteolytic microorganisms, which contribute to host nutrition. here, we purified trypsins produced by bacteria bacillus cereus, enterococcus mundtii, enterococcus gallinarum, and staphylococcus xylosus isolated from the midgut of an ... | 2017 | 28762531 |
| the resident pathobiont staphylococcus xylosus in nfkbiz-deficient skin accelerates spontaneous skin inflammation. | iκbζ, which is encoded by the nfkbiz gene, is a member of the nuclear iκb family of proteins that act as transcriptional regulators via association with nf-κb. nfkbiz-deficient (nfkbiz (-/-)) mice develop spontaneous dermatitis; however, the underlying mechanism has yet to be elucidated. in our study, we found higher skin pathology scores and more serum ige antibodies and trans-epidermal water loss in nfkbiz (-/-) than in nfkbiz-sufficient (nfkbiz (+/-)) mice. there was also greater expansion of ... | 2017 | 28740238 |
