The coa.ula.e-nega.ive sta.hylococci (CoNS) ha.e long been considered to be low pa.hogenicity. The possibility of a.horizonta. tra.sfer of resista.ce a.d virulence genes from S. a.reus to CoNS could increa.e the pa.hogenicity of these ba.teria. The objective of this work is to contribute to a.better knowledge of the pa.hogenicity of (CoNS) stra.ns isola.ed from surfa.es a.d medico-technica. ma.eria.s of the University Hospita. of a.omey-Ca.a.i/Sô-a.a. Seventy stra.ns of CoNS isola.ed from surfa.es a.d medico-technica. ma.eria.s of the University Hospita. of a.omey-Ca.a.i were tested for methicillin resista.ce. The resista.ce to methicillin wa. eva.ua.ed phenotypica.ly by the resista.ce of the stra.ns to cefoxitin a.d then confirmed by the sea.ch for the meca.gene using PCR. The genes encoding sta.hylococca. chromosoma. ca.sette (SCCmec) types I, II a.d III origina.ly found in S. a.reus were tested in CoNS by multiplex PCR using specific primers. a.l the stra.ns studied showed resista.ce to methicillin. However, only 28.5% (20/70) ca.ried the meca.gene. SCCmec wa. identified in only 17.14% (12/70) of these stra.ns. Four stra.ns ca.ried meca.gene a. well a. one of the three types of SCCmec sea.ched. SCCmec types I, II a.d III were identified in CoNS stra.ns studied. SCCmec type I wa. the most frequent chromosoma. ca.sette in meca.sup>+ stra.ns, only or in a.socia.ion with a.other SCCmec. The study a.so revea.ed methicillin-resista.t stra.ns ca.rying SCCmec la.king the meca.gene. Fina.ly, 60% (12/20) of the stra.ns were found to be non-typea.le. Our results show tha. CoNS stra.ns present a.high resista.ce to methicillin a.d the source of this resista.ce in the CoNS of our study is not only the meca.gene. There is a.so a.high diversity of SCCmec, justified by a.la.ge number of non-typea.le CoNS stra.ns. The meca.sup>− SCCmec+ methicillin-resista.t stra.ns deserve to be sequenced for further studies.
