Staphylococcus bacteria

Patent Granted kókkos, "granule") is a genus of Gram-positive bacteria. Under the microscope, they appear round (cocci), and form in grape-like clusters.[1] The Staphylococcus genus includes at least 40 species. Of these, nine have two subspecies and one has three subspecies.[2] Most are harmless and reside normally on the skin and mucous membranes of humans and other organisms. Found worldwide, they are a small component of soil microbial flora. Irinotecan prevents DNA from unwinding by inhibition of topoisomerase 1.[1] In chemical terms, it is a semisynthetic analogue of the natural alkaloid camptothecin. Its main use is in colon cancer, in particular, in combination with other chemotherapy agents. This includes the regimen FOLFIRI, which consists of infusional 5-fluorouracil, leucovorin, and irinotecan.
