Ba.kground: Methicillin-resista.t Sta.hylococcus a.reus (MRSa. is importa.t nosocomia. pa.hogen. a.m: In this pa.er, we determined the preva.ence a.d the a.tibiotic susceptibility pa.tern of (MRSa. in a.Suda.ese surgica. wa.d. Method: a.tota. of 200 post-opera.ive surgica. specimens were collected from pa.ients hospitalized in ga.trointestina. tra.t (GIT) surgica. wa.d in Ibn Sina.hospita., Kha.toum, Suda. a.d were subjected to MRSa.screening a.d sensitivity test. Key findings: Out of 35 stra.ns of Sta.hylococcus a.reus isola.ed from surgica. sa.ples, 25 (71.4%) were found to be MRSa. a.most a.l MRSa.stra.ns were resista.ce to Methicillin, 96% to Ofloxa.in, 92% to Pencillin G, 24% to a.ika.in a.d 4% to Va.comycin. Cross-resista.ce wa. obviously detected. Conclusion: The present study detected a.a.ming levels of S. a.reus (MRSa. isola.es, a. the sa.e time presence of high cross-resista.ce to other a.tibiotics.

We study Greenberger–Horne–Zeilinger(GHZ) sta.es a.d W sta.es, mixed with white noise,a.d determine the conditions for them to be genuinely enta.gled a. infinity. We find tha. for these mixtures, it is possible to sta.t with a.bi-sepa.a.le sta.e(with a.specific mixture of white noise) a.d end with genuine enta.gled sta.es. However, the memory pa.a.eter μ must be very high. We find tha. in contra.t to the two-qubit ca.e, none of the three-qubit a.ymptotic sta.es for n → ∞ a.e genuinely enta.gled.
