Isolating novel phages using Streptomyces azureus, which produces antibiotic thiostrepton, as a host, and characterizing the genomes may help us to find new tools that could be used to develop antibiotics in addition to contribute to the databases of phages and specifically, Streptomyces phages. Streptomyces phages Alsaber, Omar, Attoomi, Rowa, and ZamZam were isolated using during this study. They were isolated from enriched soil and sequenced by Illumina sequencing method. They were isolated from three different geographical regions. They are siphoviridae phages that create small clear plaques with a diameter of approximately 0.5-1 mm, except for Rowa which has cloudy plaques, and they have varied sizes of their heads and tails. ZamZam was not characterized at this time. The sequencing shows that they are circular genome with 3' sticky overhang and various genomes' sizes with high percentage of GC content with the average of 66%. Alsaber was classified under sub-cluster BD3, while Omar was categorized under sub-cluster BD2. They share the same cluster of Cluster BD. Rowa was placed in Cluster BL and Attoomi is currently a singleton that does not fit into an established cluster. Alsaber yields 76 putative genes with no tRNA, Omar 81 putative genes with 1 …

Eukaryotic platelets are small cell fragments that are released into the bloodstream from megakaryocytes, and their production is initiated in the bone marrow. They are mainly involved in blood hemostasis and thrombus formation. The newly synthesized platelets are called reticulated platelets or young platelets. Zebrafish thrombocytes are equivalent to mammalian platelets and have similar characteristics and functions. Likewise, zebrafish has both young and mature thrombocytes. Only young thrombocytes as reticulated platelets are labeled with thiazole orange. Similarly, labeling zebrafish thrombocytes with a specific concentration of DiI-C18 showed two populations of thrombocytes (DiI+ and DiI-). Again, only young thrombocytes showed DiI+ labeling. The mechanism of selective labeling of young thrombocytes by is unknown. Furthermore, there is no zebrafish line where young and mature thrombocytes are differentially labeled with fluorescence proteins. Therefore, in this study, we identified and confirmed that the RFP labeled cells of Glofish were young thrombocytes. In addition, we found that myosin light chain 2 (MLC2) promoter is expressed in young thrombocytes. We also generated a transgenic zebrafish line, GloFli fish, where the young and mature thrombocytes are labeled with red and green fluorescence proteins respectively. Furthermore, this study showed a two-fold increase in glycerol-phospholipids (GP) in mature thrombocytes …
