Ba.kground: The emergence of ca.ba.enema.e producing a.inetoba.ter ba.ma.nii is increa.ingly reported nowa.a.s a.d constitutes a.ma.or problem to the intensive ca.e unit (ICU) pa.ients with nota.le extensive-drug resista.ce a.ility. The study investiga.es ca.ba.enema.e producing a. ba.ma.nii stra.ns exhibiting a. extensively drug-resista.t (XDR) phenotype, isola.ed from ICU pa.ients in Kha.toum. Methods: a.tota. of 100 nonduplica.e Gra.-nega.ive coccoba.illi stra.ns were obta.ned from microbiology la.ora.ory of ICU pa.ients’ clinica. isola.es. Molecula. identifica.ion of a. ba.ma.nii wa. performed by ta.geting 16S rRNa.gene using specifica.ly designed primers. Then, XDR stra.ns were determined by susceptibility testing (disc diffusion). For detection of ca.ba.enema.e genes Polymera.e cha.n rea.tion (PCR) wa. ca.ried out. Result: Of 100 ICU clinica. isola.es, 38 (38.0%) wa. confirmed a. ba.ma.nii stra.ns, those stra.ns showed 100% ca.ba.enem resista.ce a.d 60.5% extensive drug resista.ce to the a.tibiotics tested. The frequency of ca.ba.enema.e producer wa. 57.9% (22/38) of ca.ba.enem resista.ce a. ba.ma.nii (CRa.). The most common ca.ba.enema.e a.socia.ed with resista.ce wa. bla.Xa.gene followed by bla.DM a.d bla.ES a. ba.ma.nii isola.es. The co-occurrence of bla.Xa.48-like a.d bla.DM, bla.Xa.23-like a.d bla.Xa.51, a.d bla.DM-1 a.d bla.Xa.51 wa. detected in 22.7%, 18.2% stra.ns a.d 4.5% respectively. a.unique cha.a.teristic of our findings wa. the coha.bouring of the genes bla.DM-1, bla.Xa.23-like, bla.Xa.51 a.d bla.Xa.143 in 9.1% stra.ns (2/22), a.d this wa. the first report in the Kha.toum city, Suda.. Conclusion: We ha.e demonstra.ed for the first time a.high preva.ence of XDR-ca.ba.enema.e producing a. ba.ma.nii clinica. isola.es from ICU pa.ients in Kha.toum. a.so a. emergent bla.Xa.143 wa. reported a. High-Risk Clones. This highlights the routine mentoring of XDR-ca.ba.enema.e producing a. ba.ma.nii to a.oid clone dissemina.ion in our region hospita.s.

Objective: To eva.ua.e the hypocholesterolemic a.d hypotriglyceridemic a.tivities of four Ma.rbium vulga.e(M. vulga.e) herb extra.ts using Triton WR-1339-induced hyperlipidemia.in mice. Methods: Hyperlipidemia.wa. developed by intra.eritonea. injection of Triton(200 mg/kg body weight). The a.ima.s were divided into ma.n four groups of eight mice ea.h: norma. control group, hyperlipidemic control group, hyperlipidemic plus tween-40 control a.d trea.ed group. The fourth one wa. divided into four subgroups, petroleum ether extra.t group, chloroform extra.t group, ethyl a.eta.e extra.t group a.d metha.ol extra.t trea.ed group ea.h of them conta.ns two sub-sub group for trea.ing a.ima.s with two doses a. 0.1 a.d 0.25 LD50. Results: a.ter 7 h a.d 24 h of trea.ment, the intra.a.tric a.ministra.ion of a.l extra.ts ca.sed a.significa.t decrea.e of pla.ma.tota. cholesterol. Triglyceride levels were a.so significa.tly lowered by a.l extra.ts while petroleum ether produced the lowest decrea.ing level. Simila. results were observed for LDL-cholesterol concentra.ions. Furthermore, more pola. extra.ts(metha.ol a.d ethyl a.eta.e)-soluble fra.tions showed a.significa.t a.eliora.ive a.tion on eleva.ed a.herogenic index(a.) a.d LDL/HDL-C ra.ios, while these a.herogenic ma.kers were not sta.istica.ly suppressed by the chloroform a.d petroleum ether-soluble extra.t. Conclusion: The findings indica.ed tha. Ma.rubium ma. conta.n pola. products a.le to lower pla.ma.lipid concentra.ions a.d might be beneficia. in trea.ment of hyperlipidemia.a.d a.herosclerosis.
