Staphylococcus aureus is one of the major causes of community and hospital-acquired infections. Bacteriophage considered as a major risk factor acquires S. aureus new virulence genetic elements. A total number of 119 S. aureus isolated from different specimens obtained from (RKH) were distinguished by susceptibility to 19 antimicrobial agents, phage typing, and PCR amplification for mecA gene. All of MRSA isolates harbored mecA gene, except three unique isolates. The predominant phage group is belonging to the (mixed group). Phage group (II) considered as an epidemiological marker correlated to β-lactamase hyper producer isolates. MRSA isolates indicated high prevalence of phage group (II) with highly increase for phage types (Ø3A), which were correlated to the skin. Phage types (Ø80/Ø81) played an important roll in Community Acquired Methicillin Resistant S. aureus (CAMRSA). Three outpatients MRSA isolates had low multiresistance against Bacitracin (Ba) and Fusidic acid (FD), considered as CAMRSA isolates. It was detected that group I typed all FD-resistant MSSA isolates. Phage groups (M) and (II) were found almost to be integrated for Gentamycin (GN) resistance especially phage type (Ø95) which relatively increased up to 20% in MRSA. Tetracycline (TE) resistant isolates typed by groups (II) and (III) in MSSA. Only one isolate resistant to Sulphamethoxazole/Trimethoprim (SXT) was typed by (III/V) alone in MSSA. MRSA isolates resistant to Chloramphenicol (C) and Ba were typed by all groups except (V). It could be concluded that (PERSA) S. aureus isolates from the wound that originated and colonized, and started to build up multi-resistance against the topical treatment antibiotics. In this study, some unique sporadic isolates for both MRSA and MSSA could be used as biological, molecular and epidemiological markers such as prospective tools.

金黄色葡萄球菌是社区和医院获得性感染的主要原因之一。被认为是主要危险因素的噬菌体获得了金黄色葡萄球菌新的毒力遗传成分。从(RKH)的不同标本中分离出的总共119株金黄色葡萄球菌通过对19种抗菌药的敏感性,噬菌体分型和mecA基因的PCR扩增来区分。除三个独特的分离株外,所有的MRSA分离株均带有mecA基因。主要噬菌体基团属于(混合基团)。噬菌体组(II)被认为是与β-内酰胺酶高产分离株相关的流行病学标记。 MRSA分离物表明噬菌体组(II)的流行率很高,而与皮肤相关的噬菌体类型(Ø3A)则大大增加。噬菌体类型(Ø80/Ø81)在社区获得的耐甲氧西林金黄色葡萄球菌(CAMRSA)中起着重要作用。三名门诊MRSA分离株对杆菌肽(Ba)和梭链孢酸(FD)的多重耐药性较低,被认为是CAMRSA分离株。检测到第一组键入了所有耐FD的MSSA分离株。发现噬菌体组(M)和(II)几乎对庆大霉素(GN)具有抵抗力,特别是在MRSA中相对增加高达20%的噬菌体类型(Ø95)。在MSSA中按(II)和(III)组分类的四环素(TE)耐药菌株。在MSSA中,仅通过(III / V)分型了一种对Sulphamethoxazole / Trimethoprim(SXT)有抗性的菌株。除(V)外,所有组均对氯霉素(C)和Ba具有抗性的MRSA分离株进行了分型。可以得出结论,(PERSA)金黄色葡萄球菌从起源和定殖的伤口中分离出来,并开始建立对局部治疗抗生素的多重耐药性。在这项研究中,MRSA和MSSA的一些独特的零星分离株可用作生物学,分子和流行病学标记,例如前瞻性工具。
