    Detection of aerial microfungus flora potential opportunist infection agent, in the intensive care unit of the chest disease department of a hospital in izmir
    (2012) Abaci O.; Haliki-Uztan A.; Ates M.; Bacakoglu F.
    The biodiversity and concentrations of different genera of indoor airborne fungi, a potential opportunist infection factor, in the respiratory intensive care unit of the pulmonary diseases department, medical faculty of Ege University, were investigated. To accomplish the purpose, air samples were collected at 4 different points of intensive care unit for 10 days with a Merck MAS 100 air sampler. After identification of isolates obtained from 566 microfungal colonies counted, 12 different species belonging to 8 genera were determined (Aspergillus, Pénicillium, Alternaria, Cladosporium, Mucor, Rhizopus, Fusarium, and Trichodermd). In this study, aimed to emphasize the importance of monitoring the presence of airborne fungal flora, particularly Aspergillus spp, in the departments of a hospital where patients of high-risk groups were hospitalized, we could not isolate A.fumigatus, an opportunist pathogen. by psp.

    Determining candida spp. incidence in denture wearers
    (2010) Abaci O.; Haliki-Uztan A.; Ozturk B.; Toksavul S.; Ulusoy M.; Boyacioglu H.
    The aim of this study was to determine Candida spp. incidence in the oral cavity of denture wearers and characterize predisposing factors in denture-related stomatitis (DRS). Three groups of denture wearers and a control group were evaluated for DRS according to Newton's classification. The amount of yeast in saliva and the presence of yeast on mucosal surfaces were determined by phenotyping methods, and the impact of some risk factors on candidal carriage was evaluated. The development of DRS is most common in complete prosthesis users. When the count of yeast in saliva is ?400 cfu/ml, the frequency of DRS is increased. In individuals who develop DRS, the most frequently encountered species that was identified as C. albicans. Prosthetic hygiene was related to the intensity of candidal growth and the development of DRS. C. albicans live as saprophyte in the oral cavity. But, it is capable of causing infection if there are predisposing conditions related to the host. Usage of removable prosthesis may cause these microorganisms to gain pathogenicity. © 2010 Springer Science+Business Media B.V.

    Investigation of extracellular phospholipase and proteinase activities of Candida species isolated from individuals denture wearers and genotypic distribution of Candida albicans strains
    (2011) Abaci O.
    In order to determine the relationship between the development of denture related stomatitis (DRS) and the production of phospholipase and proteinase by Candida species, 156 Candida isolates isolated from the individuals in the control group and from the individuals different denture wearers were included in this study. According to the results of the study, C. albicans strains were determined to produce high levels of phospholipase and proteinase. It was also determined that the prevalence of phospholipase and proteinase activities in C. albicans strains isolated from individuals with DRS and from the individuals without DRS was not different. In order to determine genotypic variation of 109 C. albicans strains isolated, CA-INT-L and CA-INT-R primers specific to the site of the transposable group I intron of the 25S rRNA gene (rDNA) region were used. As a result, it was considered that, there were several other virulence factors belonging to the microorganism which played a role in the development mechanisms of the infection caused by C. albicans. In addition, according to the results of microbial genotyping, it was determined that there were no C. albicans strains specifically responsible for the development of DRS. © 2011 Springer Science+Business Media, LLC.

    Weighted network analysis of out-group candidates in a phylogenetic tree of B. Bassiana
    (Parlar Scientific Publications, 2017) Haliki E.; Yoltas A.; Abaci O.; Haliki-Uztan A.
    The investigation of phylogenetic tree dendrograms in the concept of weighted networks is essential not only for the analysis of the sequence homology of strains but also for the importance of strains considered to be nodes of the network. For instance, weighted centrality measures of any phylogenetic tree indicate the lower scores for the out-groups having less homology with the in-group making it considered to be ineffective for a dendrogram design. However biological usages have revealed the case in a different way. Relative to the relevant DNA region, this paper proposes detailed assumptions that the network structure of phylogenetic trees has a great reviewability on a bridge between close and distant out-groups. We demonstrate our computations on a verified phylogenetic tree of the entomopathogenic fungus Beauveria bassiana (Balsamo-Crivelli) Vuillemin, whose diversity and distribution were assessed throughout an extensive soil survey carried out in Turkey during 2013 and 2014. © by PSP.
