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: 1.3 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: 2.6 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: 0.00079 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: 0.24 SJR: 0.429 SNIP: 0.287 CiteScore™:: 2.7 H-Index: 81

ABSTRACT

Eukaryotes have been threatened by microbial infections throughout their phylogenetic history. Today, infections are found in all taxa of Eukaryotes. The diversity of infectious microorganisms — most of them intracellular — and their biological strategies is remarkable and by far exceeds what we know about human pathogens. The search for infections in the wide spectrum of protozoa has led to the discovery of more and more intracellular bacteria and other microorganisms. This paper provides an introduction into the diversity of intracellular microorganisms in protozoa and gives a few examples of such symbioses that have been studied in detail. Special emphasis is put on infection of the ciliate Paramecium by Holospora bacteria, which invade the host nuclei with high efficacy.
