Molecular Characterization of Tb, a New Approach for an Ancient Brucellaphage
نویسندگان
چکیده
Tb (Tbilisi), the reference Brucellaphage strain, was classified as a member of the Podoviridae family with icosahedral capsids (57 +/- 2 nm diameter) and short tails (32 +/- 3 nm long). Brucellaphage DNA was double stranded and unmethylated; its molecular size was 34.5 kilobase pairs. Some sequences were found through RAPD analysis, TA cloning technology, and structural proteins were observed by using SDS-PAGE. Thus, the results have laid the foundation for the wider use of Brucellaphage's basic mechanisms and practical applications.

F1 and Tbilisi Are Closely Related Brucellaphages Exhibiting Some Distinct Nucleotide Variations Which Determine the Host Specificity
We report on the 41,143-bp genome of brucellaphage F1, a podovirus that infects several Brucella species. The F1 genome is almost identical to the genome of brucellaphage Tb. However, some structural proteins of the phages exhibit extensive polymorphisms and might be responsible for their different host ranges.
متن کاملEmulation, Model Identification and New-approach Characterization of a PV Panel (TECHNICAL NOTE)
This paper provides experimental and simulation tools to characterize a Photo-Voltaic (PV) panel. To achieve this objective, we start from a PV electrical model and we propose a circuit using Diode-based-equivalent PV (DBEPV) panel. This circuit is presented as a prototype of an equivalent PV panel. It is designed to emulate a real PV module in different climatic conditions (irradiance and temp...

In an attempt to characterize Theileria parva parasites circulating in South Sudan cattle , polymerase chain reaction (PCR)-based assays were carried out using four single copy encoding antigen genes p104, PIM, p150 and p67 in addition to one microsatellite MS321. A total of 20 bovine DNA samples from two locations in South Sudan were included in this study, in addition to two references stra...
متن کاملThinking Towards Peace: On Triades and New Cosmology of the Mesocosm
This paper has three parts. In the first part, we bring to the fore an ancient Vedic concept of mesocosm and discuss its religious and cosmic significance within Indian religion. This part also brings an initial approach towards philosophy of spirituality by focusing on the role of breath within the very concept of mesocosm. In the second part, based on our preliminary analysis, we present an o...

In this study, molecular characterization of Echinococcus granulosus sample obtained from water buffalo originating from southwest of Iran was performed using comparative sequence analysis of cox1 mitochondrial gene. DNA was extracted from protoscoleces removed from hydatid cyst from the liver of a 2-year-old male buffalo slaughtered in Khuzestan province. Molecular and phylog...
