    Compared to the higher fungi (Dikarya), taxonomic and evolutionary studies on the basal clades of fungi are fewer in number. Thus, the generic boundaries and higher ranks in the basal clades of fungi are poorly known. Recent DNA based taxonomic studies have provided reliable and accurate information. It is therefore necessary to compile all available information since basal clades genera lack updated checklists or outlines. Recently, Tedersoo et al. (MycoKeys 13:1--20, 2016) accepted Aphelidiomycota and Rozellomycota in Fungal clade. Thus, we regard both these phyla as members in Kingdom Fungi. We accept 16 phyla in basal clades viz. Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota. Thus, 611 genera in 153 families, 43 orders and 18 classes are provided with details of classification, synonyms, life modes, distribution, recent literature and genomic data. Moreover, Catenariaceae Couch is proposed to be conserved, Cladochytriales Mozl.-Standr. is emended and the family Nephridiophagaceae is introduced

    HIV-1 genetic diversity and demographic characteristics in Bulgaria.

    HIV-1 strain diversity in Bulgaria is extensive and includes contributions from nearly all major subtypes and the Circulating Recombinant Forms (CRF): 01_AE, 02_AG, and 05_DF. Prior to this study, HIV-1 sequence information from Bulgaria has been based solely on the pro-RT gene, which represent less than 15% of the viral genome. To further characterize HIV-1 in Bulgaria, assess participant risk behaviors, and strengthen knowledge of circulating strains in the region, the study "Genetic Subtypes of HIV-1 in Bulgaria (RV240)" was conducted. This study employed the real time-PCR based Multi-region Hybridization Assay (MHA) B/non-B and HIV-1 sequencing to survey 215 of the approximately 1100 known HIV-1 infected Bulgarian adults (2008-2009) and determine if they were infected with subtype B HIV-1. The results indicated a subtype B prevalence of 40% and demonstrate the application of the MHA B/non-B in an area containing broad HIV-1 strain diversity. Within the assessed risk behaviors, the proportion of subtype B infection was greatest in men who have sex with men and lowest among those with drug use risk factors. During this study, 15 near full-length genomes and 22 envelope sequences were isolated from study participants. Phylogenetic analysis shows the presence of subtypes A1, B, C, F1, and G, CRF01_AE, CRF02_AG, CRF05_DF, and one unique recombinant form (URF). These sequences also show the presence of two strain groups containing participants with similar risk factors. Previous studies in African and Asian cohorts have shown that co-circulation of multiple subtypes can lead to viral recombination within super-infected individuals and the emergence of new URFs. The low prevalence of URFs in the presence of high subtype diversity in this study, may be the result of successful infection prevention and control programs. Continued epidemiological monitoring and support of infection prevention programs will help maintain control of the HIV-1 epidemic in Bulgaria

    WOS: 000443093100001fifty bacterial cultures were isolated from 156 soil samples. In order to identify six bacteria in both systems, a fatty acid methyl ester (FAMEs) analysis was conducted, and carbon utilization profiles were assessed, using microbial identification, Biolog Microplac Systems, and the VITEK bacterial identification systems (bioMerieux, Prod. No. 21341 and 21342). Results showed that four species of Bacillus ssp., isolated from soil, were safe and efficient biological control agent for plant pests in Ordu, Turkey. These bacteria were Bacillus mycoides, B. cereus, B. thuringiensis, Paenibacillus validus, B. atrophaeus, and Arthrobacter globiformis. Laboratory tests were conducted to assess the potential of the isolates against the great spruce bark beetle, Dendroctonus micans (Kugelann) (Coleoptera: Curculionidae, Scolytinae) (Curculionidae, Scolytinae). Mortality rates of larvae and adults were 60 and 50%, 40 and 30%, and 80 and 70% when using B. mycoides, B. cereus, and B. thuringiensis, respectively. P. valid us, B. atrophaeus, and A. globiformis showed insufficient rates of mortality, 30 and 20% on the larvae and adults of D. micans, respectively. Also, these isolates had no antimicrobial effect on pathogen microorganisms. They have, however, a lethal effect on some insect groups that are agriculture and forest pests. The results indicated that the Bacillus isolates in question can be used as one of the biological control agent
