Comparative Sequence Analysis ofMycobacterium lepraeand the New Leprosy-CausingMycobacterium lepromatosis
2009
ABSTRACTMycobacterium lepromatosisis a newly discovered leprosy-causing organism. Preliminary phylogenetic analysis of its 16S rRNA gene and a few other gene segments revealed significant divergence fromMycobacterium leprae, a well-known cause of leprosy, that justifies the status ofM. lepromatosisas a new species. In this study we analyzed the sequences of 20 genes and pseudogenes (22,814 nucleotides). Overall, the level of matching of these sequences withM. lepraesequences was 90.9%, which substantiated the species-level difference; the levels of matching for the 16S rRNA genes and 14 protein-encoding genes were 98.0% and 93.1%, respectively, but the level of matching for five pseudogenes…
Distribution ofLeprariain Latvia in Relation to Tree Substratum and Deciduous Forest Type
2012
The aim of the study was to evaluate the distribution of Lepraria lichen species in dry deciduous forests, in relation to tree substratum and forest characteristics. In total, 34 localities with 1020 trees (13 tree species) were studied in different parts of Latvia. Lepraria spp. were found on 642 trees: L. eburnea on 8 trees, L. incana on 80 trees, and L. lobificans on 568 trees. Lepraria eburnea was recorded for the first time in Latvia. Tree species, tree bark crevice depth, inclination, pH and forest type were the most important variables explaining the presence of Lepraria species. Lepraria incana was associated with Quercus robur and Tilia cordata, while L. lobificans was associated w…
Molecular phylogeny and ultrastructure of the lichen microalga Asterochloris mediterranea sp. nov. from Mediterranean and Canary Islands ecosystems
2015
The microalgae of the genus Asterochloris are the preferential phycobionts in Cladonia, Lepraria and Stereocaulon lichens. Recent studies have highlighted the hidden diversity of the genus, even though phycobionts hosting Cladonia spp. in Mediterranean and Canarian ecosystems have been poorly explored. Phylogenetic analyses were made by concatenation of the sequences obtained with a plastid -LSU rDNA- and two nuclear -ITS rDNA and actin- molecular markers of the phycobionts living in several populations of Cladonia convoluta-C. foliacea complex, C. rangiformis and C. cervicornis species widely distributed in these areas in a great variety of substrata and habitats. A new strongly supported …
Malaltia i salut en l'obra de Francesc Eiximenis
2010
Diversos autors han analitzat els voluminosos tractats de Francesc Eiximenis, especialment pel que fa a matèries relacionades amb la teologia moral, però també sobre altres temes, com la guerra i la pau, l’astrologia, el govern, la cuina i el menjar, i d’altres. En aquest article ens proposem apropar-nos a com Eiximenis tracta el tema dels hospitals, medicina, salut i malaltia. Eiximenis es preocupava de les necessitats del poble que sofria tot tipus de malalties; a part d’haver viscut durant diverses epidèmies, que provocà moltes morts a la península, també suggerí als jurats de València un bon sistema d’hospitals i on s’haurien de construir, i també els cridà l’atenció respecte de les def…
