The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

RESUMO

The entomopathogenic fungus Cod-MK1201 was isolated from a dead cicada nymph. Three regions of ribosomal nuclear DNA, the internal transcribed spacers of nuclear ribosomal DNA repeats (ITS), the partial small subunit of rDNA (nrSSU) , and the partial large subunit of rDNA (nrLSU), and two protein-coding regions, the elongation factor 1α (EF-1α), and the largest subunit of the RNA polymerase II (rpb1) gene, were sequenced and used for fungal identification. The phylogenetic analysis of the ITS and the combined data set of the five genes indicated that the fungal isolate Cod-MK1201 is a new strain of Cordyceps sp. that is closely related to Cordyceps nipponica and C. kanzashiana. Crude extracts of mycelium-cultured Cod-MK1201 were obtained using distilled water and 50% (v/v) ethanol, and the antibacterial activity of each was determined. Both extracts had activity against Gram-positive and Gram-negative bacteria, but the ethanol extract was the more potent of the two. The antibacterial activity of the protein fractions of these extracts was also determined. The protein fraction from the ethanol extract was more antibacterial than the protein fraction from the aqueous extract. Three antibacterial constituents including adenosine, the total phenolic content (TPC), and the total flavonoid content (TFC) was also determined. The results showed that the adenosine content, the TPC, and the TFC of the ethanol extract were more active than those of the aqueous extract. Moreover, synergism was detected between these antibacterial constituents. In conclusion, the entomopathogenic fungal isolate Cod-MK1201 represents a natural source of antibacterial agents.
