The association in between SCCmec kinds and antimicrobial resistance pattern is shown in Table 2.DiscussionS. aureus infections are increasingly reported in public-health arenas. MRSA infections are among the Semaphorin-3A/SEMA3A Protein Storage & Stability primary causes ofmarked morbidity and mortality, which can impose a high burden on healthcare costs [5]. Annually, HA-MRSA infections occur in around 19 000 hospitalized American patients; this number is comparable to the frequency of deaths caused by AIDS and tuberculosis [13]. In our study, the mecA gene was found in 29 isolates (40.two ). In addition, all of those isolates showed phenotypic resistance to oxacillin. The prevalence of this gene with all the distinct frequencies has been reported in other regions of Iran [146]. The differences within the distribution in the mecA gene may be explained by the populations studied or by the diversity varieties of the clinical specimens. In addition, in the study conducted by Goudarzi et al. [16] in Tehran, most MRSA isolates were obtained from hospitalized patients in intensive care units. In addition, intensive care units are viewed as to become highrisk places for dissemination of MRSA infections [17]. Having said that, the prevalence on the mecA gene in our study was comparable to previously reported research from other countries: 36.six in Greece, 46 in Israel, 38.3 in Italy and 45.76 in the Philippines [18]. Molecular typing of MRSA is an crucial method for the identification of your origin of strains, epidemiologic investigation and antibiotic therapy [19]. In our study, SCCmec typing recognized 55.1 of MRSA isolates as sort III. In line with the information, most MRSA isolates inside the present study may have originated from HA-MRSA isolates.

The frequency of SCCmec form III was reported as 74.three in Shiraz [20], 98 in Tehran [14], 69.8 in Tabriz [15], 91 in Isfahan [21] and 45 within the provinces of western Iran [22]. In concordance with several studies from Iran, SCCmec type III has been reported to be the predominant sort amongst MRSA strains isolated from most Asian countries. However, in Japan and Korea, the predominant SCCmec kind amongst MRSA strains was sort II [6]. Some researchers have reported a rise in the prevalence of HA-MRSA strains, with SCCmec variety IV oc.
