This is a report of a revision of 565 herbarium specimens of lichens, lichenicolous or non-lichenized fungi and additional locality records of common species produced from a visit of the Russian-Finnish expedition to Vodlozersky National Park right after its foundation in 1991. The analyzed collection and field records represent the earliest information about the lichen flora of the territory of the park. In total, 177 species are listed including 173 lichens, 3 non-lichenized and 1 lichenicolous fungi. Xylographa rubescens is new to the Republic of Karelia. Twenty two species are reported for the first time for biogeographic province Karelia transonegensis; 47 species for the Karelian part of Vodlozersky National Park; and 17 species for the whole territory of the park.

Gall Midges

Галлицы-карпофаги в Палеарктике повреждают 14 типов плодов древесно-кустарниковых растений из 16 семейств. Они обычно специфичны по отношению к роду растения, являясь монофагами и олигофагами (Kaltenbachiola, Plemeliella, Resseliella). Внутри семян покрытосеменных растений развиваются очень редко (Semudobia). Всего 10 видов галлиц из 5 родов выявлено в плодах и семенах голосеменных растений, 39 видов из 15 родов – на покрытосеменных. В шишках хвойных и серёжках берёз известны наиболее крупные комплексы галлиц. Общих видов среди плодовых, семенных и цветочных галлиц не обнаружено. Галлицы, развивающиеся в плодах и семенах растений, освоили их независимо от цветочных галлиц. Галлицы предпочитают сухие плоды, преимущественно шишки, крылатки, коробочки; среди сочных плодов – костянки и ложные ягоды. Fruit and seed gall midges in the Palearctic damage 14 types of fruit of tree and shrub plants from 16 families. They are usually specific to the genus of the plant, being monophagous and oligophagous (Kaltenbachiola, Plemeliella, Semudobia). They develop very rarely inside seeds of angiosperms (Semudobia). A total of 10 species of gall midges from 5 genera are found in fruits and seeds of gymnosperms plants, 39 species from 15 genera are known on angiosperms. The largest complexes of gall midges are known in the cones of conifers and earrings of birch. There were no common species among fruit, seed and flower gall midges. Gall midges developing in fruits and seeds of plants began to utilize them irrespective of flower gall midges. Gall midges prefer dry fruits, mostly cones, achene, capsules; among the juicy fruits they prefer stone-fruit and false berries.

Abstract Background The relative contribution of bacterial infections to febrile disease is poorly understood in many African countries due to diagnostic limitations. This study screened pediatric and adult patients attending 4 healthcare facilities in Ibadan, Nigeria, for bacteremia and malaria parasitemia. Methods Febrile patients underwent clinical diagnosis, malaria parasite testing, and blood culture. Bacteria from positive blood cultures were isolated and speciated using biochemical and serological methods, and Salmonella subtyping was performed by polymerase chain reaction. Antimicrobial susceptibility was tested by disk diffusion. Results A total of 682 patients were recruited between 16 June and 16 October 2017; 467 (68.5%) were <18 years of age. Bacterial pathogens were cultured from the blood of 117 (17.2%) patients, with Staphylococcus aureus (69 [59.0%]) and Salmonella enterica (34 [29.1%]) being the most common species recovered. Twenty-seven (79.4%) of the Salmonella isolates were serovar Typhi and the other 7 belonged to nontyphoidal Salmonella serovarieties. Thirty-four individuals were found to be coinfected with Plasmodium falciparum and bacteria. Five (14.7%) of these coinfections were with Salmonella, all in children aged <5 years. Antimicrobial susceptibility testing revealed that most of the Salmonella and Staphylococcus isolates were multidrug resistant. Conclusions The study demonstrates that bacteria were commonly recovered from febrile patients with or without malaria in this location. Focused and extended epidemiological studies are needed for the introduction of typhoid conjugate vaccines that have the potential to prevent a major cause of severe community-acquired febrile diseases in our locality.

A new species of Trichopeltarion A. Milne-Edwards, 1880, is described from off coast of Brazil, namely Trichopeltarion pezzutoi n. sp. The new species is compared to its Atlantic congeners, Trichopeltarion nobile A. Milne-Edwards, 1880, and Trichopeltarion intesi (Crosnier, 1981). The record of T. nobile from Brazil should actually be attributed to T. pezzutoi n. sp. The differences between the genera Trichopeltarion and Peltarion Jacquinot, 1847 are discussed.

AbstractThe phylum Porifera and their symbionts produce a wide variety of bioactive compounds, playing a central role in their ecology and evolution. In this study, four different extracts (obtained by non-polar and semi-polar extraction methodologies) of the Mediterranean sponge Ircinia oros were tested through a multi-bioassay integrated approach to assess their antifouling potential. Tests were performed using three common species, associated with three different endpoints: the marine bacterium Aliivibrio fischeri (inhibition of bioluminescence), the marine diatom Phaeodactylum tricornutum (inhibition of growth), and different development stages of the brackish water serpulid Ficopomatus enigmaticus (gametes: sperm motion, vitality inhibition and cellular damage; larvae: development; adults: AChE (acetylcholinesterase)-inhibitory activity). The effects of extracts were species specific and did not vary among different extraction methodologies. In particular, no significant reduction of bioluminescence of A. fischeri was observed for all tested samples. By contrast, extracts inhibited P. tricornutum growth and had toxic effects on different F. enigmaticus’ developmental stages. Our results suggest that the proposed test battery can be considered a suitable tool as bioactivity screening of marine natural products.

AbstractOne hundred forty-nine carbapenem-resistant Enterobacterales from clinical samples obtained between April 2014 and November 2017 were subjected to whole genome sequencing and multi-locus sequence typing. Klebsiella pneumoniae (81, 54.4%) and Escherichia coli (38, 25.5%) were the most common species. Genes encoding metallo-β-lactamases were detected in 68 (45.8%) isolates, and OXA-48-like enzymes in 60 (40.3%). blaNDM-1 (45; 30.2%) and blaOXA-48 (29; 19.5%) were the most frequent. KPC-encoding genes were identified in 5 (3.6%) isolates. Most common sequence types were E. coli ST410 (8; 21.1%) and ST38 (7; 18.4%), and K. pneumoniae ST147 (13; 16%) and ST231 (7; 8.6%).

Butanol Stress

Biobutanol is a promising alternative fuel with impaired microbial production thanks to its toxicity. Lactiplantibacillus plantarum (L. plantarum) is among the few bacterial species that can naturally tolerate 3% (v/v) butanol. This study aims to identify the genetic factors involved in the butanol stress response of L. plantarum by comparing the differential gene expression in two strains with very different butanol tolerance: the highly resistant Ym1, and the relatively sensitive 8-1. During butanol stress, a total of 319 differentially expressed genes (DEGs) were found in Ym1, and 516 in 8-1. Fifty genes were upregulated and 54 were downregulated in both strains, revealing the common species-specific effects of butanol stress: upregulation of multidrug efflux transporters (SMR, MSF), toxin-antitoxin system, transcriptional regulators (TetR/AcrR, Crp/Fnr, and DeoR/GlpR), Hsp20, and genes involved in polysaccharide biosynthesis. Strong inhibition of the pyrimidine biosynthesis occurred in both strains. However, the strains differed greatly in DEGs responsible for the membrane transport, tryptophan synthesis, glycerol metabolism, tRNAs, and some important transcriptional regulators (Spx, LacI). Uniquely upregulated in the butanol-resistant strain Ym1 were the genes encoding GntR, GroEL, GroES, and foldase PrsA. The phosphoenolpyruvate flux and the phosphotransferase system (PTS) also appear to be major factors in butanol tolerance.
