Online published on 20 December, 2018. Abstract The present study aimed to isolating and diagnosing of Staphylococcus spp., which forms the biofilmfrom different areas of males and females workers bodies in units of: magnetic resonance imaging (MRI), computerized axial tomography (CAT) and x-ray as well as restaurants, using some phenotypic and genotypic characterization methods as well as testing their ability to phenotypically and genetically of biofilms formation. Isolates were collected within the range of hospitals in Al-Diwaniyah Governorate at the period from 1/11/2016 till 1/4/2017 and a total of 200 samples distributed equally on predefined isolation units. The results showed that superior the bacterial isolation percent of male workers in these units exceeded the females at all sources of isolation. Staphylococcus isolates were diagnosed by using the API-20 Staph systemand the species of genus (Staph. epidermidis, Staph. haemolyticus and Staph. aureus) have been affiliated a higher frequency of isolates number (57 isolates), which were divided between 23, 21 and 13 isolates, respectively. The isolates consisted of biofilm formation were 13 isolates from Staph. epidermids, 16 isolates from Staph. haemolyticus and 10 isolates of Staph. aureus. Genetic diagnosis of all isolates was done by using the PCR technique in terms of having a 16S rRNA gene as well as investigating the ability of Staphylococcusisolates to biofilms formation in terms of having the icaA gene. The results of phenotypic investigation were identical to the results of genetic investigation. Top Keywords Genotypic characterization, Staphylococcus, Biofilms formations. Top |
