“…Kocuria türlerinin neden olduğu infektif endokardit olgusu oldukça nadirdir [7] . Literatürdeki ilk hasta iskemik bağırsak hastalığı nedeniyle opere edilen ve izole kısa bağırsak sendromu nedeniyle santral venöz kateterden total parenteral nütrisyon tedavisi gören bir hastadır.…”

“…Kocuria türleri stafilokoklardan farklı olarak basitrasin ve lizozoma duyarlı; nitrofurantoin/furazolidon ve lizostafine dirençlidir ancak biyokimyasal özellikleri oldukça değişken olduğundan ticari veri bankaları tüm fenotiplerini içermemekte ve yanlış tanımlamalara neden olabilmektedir. Literatürde Kocuria türlerinin Vitek (bioMérieux), Vitek2 (bioMérieux), API (bioMérieux) ve BD Phoneix sistemleriyle koagülaz-negatif stafilokok, mikrokok ve dermakoklar ile karıştırılabileceği ve kesin doğrulamanın 16S rRNA gen sekans analiziyle yapılması önerilmiştir [7,8] . Çalışmamızda gen sekans analiziyle doğrulama yapılamamış ancak BD BBL Crystal ve Phoenix otomatize sistemi beraber kullanılmıştır.…”

“…Literatürde Kocuria türlerinin duyarlılık özellikleri ile yapılan çalışmalar olgu azlığı nedeniyle sınırlı olup duyarlılık eşik değerleri halen tam bilinmemekte ve bu nedenle stafilokoklar için belirlenmiş eşik değerler kullanılmaktadır [2,7] . Savini ve arkadaşlarının Kocuria türlerinin antibiyotik duyarlığını irdelediği bir derlemede beta-laktam, kinolon, linkozamid ve kotrimoksazole karşı değişen duyarlılıklar saptanmış; glikopeptid, streptogramin, fusidik asit, rifampisin ve linezolide karşı direnç bildirilmemiştir [2] .…”

Kocuria türleri Micrococcacae ailesi içinde Micrococcineae alt takımı ve Actinomycetales takımında yer alan fakültatif anaerop, katalaz-pozitif, koagülaz-negatif, gram-pozitif koklardır. Kocuria türleri doğada yaygın bulunmakla beraber insanlarda deri, mukoz membran ve orofarenksin normal flora elemanları arasında yer alır. Literatürde Kocuria türleri ile bildirilen infeksiyon sayısı azdır. İnfektif endokardit etkenleri arasında Kocuria türlerine bağlı endokardit bildirimi ayrıca oldukça nadirdir. Burada Kocuria kristinae'nın etken olduğu nativ kapak tutulumlu toplum kökenli iki infektif endokardit olgusu sunuldu.

Bacterial diversity of 15 extra virgin olive oils, obtained from different Italian varieties, including Frantoio, Coratina, Bosana, and Semidana, was analyzed in this study. All bacterial isolates were genotyped using RAPD and REP-PCR method and grouped by means of cluster analyses. Sequencing of 16S rDNA of 51 isolates, representative of 36 clusters, led to the identification of Bacillus spp., Brevibacillus spp., Micrococcus spp., Staphylococcus spp., Pantoea spp., Kocuria spp., Lysinbacillus spp., and Lactobacillus spp., most of which reported for first time in olive oils. Phenotypic characterization of the 51 isolates, some of which ascribed to potentially probiotic species, indicate that two of them have beta-glucosidase activity while 37% present lipolytic activity. Preliminary evaluation of probiotic potential indicates that 31% of the isolates show biofilm formation ability, 29% acidic pH resistance, and 25% bile salt resistance. Finally, 29% of the isolates were sensitive to antibiotics while the remaining 71%, that include bacterial species well-recognized for their ability to disseminate resistance genes in the environment, showed a variable pattern of antibiotic resistance. The results obtained underline that microbial diversity of extra virgin olive oils represents an unexpected sink of microbial diversity and poses safety issues on the possible biotechnological exploitation of this microbial biodiversity.

“…For example, Erwinia persicina was not selected for these assays due to its capacity of infecting plants, causing chlorosis and necrosis in leaves (González et al, 2007). Isolates from the Kocuria genus were not selected due to increasing incidence of different types of Kocuria infection, mostly in immunocompromised hosts or hosts with severe underlying diseases, causing infections such as peritonitis, bacteremia or endocarditis (Purty et al, 2013). Finally, isolation from clinical specimens of bacteria from the genera Microbacterium, Cellulosimicrobium and Curtobacterium have been reported, therefore isolates from these species were not selected for biological activity assays (Francis et al, 2011;Gneiding et al, 2008;Zamora et al 2018).…”

Microbial communities that are exposed to sunlight typically share a series of adaptations to deal with the radiation they are exposed to, including efficient DNA repair systems, pigment production and protection against oxidative stress, which makes these environments good candidates for the search of novel antioxidant microorganisms. In this research project, we isolated potential antioxidant pigmented bacteria from a dry and highly-irradiated extreme environment: solar panels. High-throughput in vivo assays using Caenorhabiditis elegans as an experimental model demonstrated the high antioxidant and ultravioletprotection properties of these bacterial isolates that proved to be rich in carotenoids. Our results suggest that solar panels harbor a microbial community that includes strains with potential applications as antioxidants.
