Incidence and molecular typing of Mycobacterium kansasii in a defined geographical area in Catalonia, Spain

A retrospective population-based study was conducted between January 1990 and December 1998 to investigate the incidence of Mycobacterium kansasii disease and the heterogeneity of the isolates in a well-defined geographical area in Catalonia, Spain. A total of 136 patients were identified. Overall incidence and incidence in AIDS patients was 1. 5 (95% CI 1.2-1.8) and 1089.6 (95% CI 689-1330) cases/100 000 persons per year respectively, which is comparable to that reported from most of other geographical areas. Surprisingly, although 7 subtypes of M. kansasii have been consistently reported, in the present study 91 of the 93 isolates (97.8%) tested for genotype were subtype I, regardless of HIV status of the patients. In conclusion, the high rate of infection observed in the AIDS population contributes significantly to the burden of the M. kansasii disease in our area. M. kansasii disease in our geographical area was almost exclusively caused by subtype I regardless of HIV status

Palaeogenomics of Upper Palaeolithic to Neolithic European hunter-gatherers

Modern humans have populated Europe for more than 45,000 years. Our knowledge of the genetic relatedness and structure of ancient hunter-gatherers is however limited, owing to the scarceness and poor molecular preservation of human remains from that period. Here we analyse 356 ancient hunter-gatherer genomes, including new genomic data for 116 individuals from 14 countries in western and central Eurasia, spanning between 35,000 and 5,000 years ago. We identify a genetic ancestry profile in individuals associated with Upper Palaeolithic Gravettian assemblages from western Europe that is distinct from contemporaneous groups related to this archaeological culture in central and southern Europe, but resembles that of preceding individuals associated with the Aurignacian culture. This ancestry profile survived during the Last Glacial Maximum (25,000 to 19,000 years ago) in human populations from southwestern Europe associated with the Solutrean culture, and with the following Magdalenian culture that re-expanded northeastward after the Last Glacial Maximum. Conversely, we reveal a genetic turnover in southern Europe suggesting a local replacement of human groups around the time of the Last Glacial Maximum, accompanied by a north-to-south dispersal of populations associated with the Epigravettian culture. From at least 14,000 years ago, an ancestry related to this culture spread from the south across the rest of Europe, largely replacing the Magdalenian-associated gene pool. After a period of limited admixture that spanned the beginning of the Mesolithic, we find genetic interactions between western and eastern European hunter-gatherers, who were also characterized by marked differences in phenotypically relevant variants.Open access funding provided by Max Planck Society.

Presència de Tetralophodon Falconer, 1857 (Proboscidea) al Vallesià de la fossa de l’Empordà (Vaca Morta; Cruïlles, Monells i Sant Sadurní de l’Heura; Baix Empordà)

En aquest article es fa un repàs bibliogràfic de les dades existents sobre el jaciment de Vaca Morta (Cruïlles, Monells i Sant Sadurní de l’Heura; Baix Empordà) datat biostratigràficament a la MN 9. Per primera vegada, es descriu i es diagnostica un fragment de peça dentària de mastodont bunolofodont procedent de la part alta de la sèrie estratigràfica d’aquest jaciment. La morfologia simplificada de les cúspides i les amplades bucolinguals de les crestes i del taló la situen clarament a la línia de les terceres molars de Tetralophodon (Falconer, 1857) de Polinyà (Vallès Occidental, Barcelona) i Crevillent (Baix Vinalopó, Alacant). Així, a partir de les dades morfomètriques s’identifica el material com una molar superior dreta de Tetralophodon cf. longirostris (Kaup, 1832).Presence of Tetralophodon (Proboscidea) from the Vallesian of the Empordà basin (Vaca Morta; Cruïlles, Monells i Sant Sadurní de l’Heura; Baix Empordà) A bibliographic review of the available data from the fossil site of Vaca Morta (MN 9) (Cruïlles, Monells i Sant Sadurní de l’Heura; Baix Empordà) is given in the present paper. A fragmented tooth belonging to a bunolophodont mastodon, which was found at the upper part of the stratigraphic series of the site, has been described for the first time. The simple morphology of the cusps and the buccolingual widths of the lophs and the talon put this piece in close relation with third molars of Tetralophodon (Falconer, 1857) of Polinyà (Vallès Occidental, Barcelona) and Crevillent (Baix Vinalopó, Alicante). In conclusion, based on morphometric parameters the tooth is identified as an upper right molar of a Tetralophodon cf. longirostris (Kaup, 1832).Presencia de Tetralophodon (Proboscidea) en el Vallesiense de la cuenca del Ampurdán (Vaca Morta; Cruïlles, Monells i Sant Sadurní de l’Heura; Baix Empordà) En este artículo se hace un repaso bibliográfico de los datos existentes sobre el yacimiento de Vaca Morta (Cruïlles, Monells i Sant Sadurní de l’Heura; Baix Empordà) fechado biostratigráficamente en la MN 9. Por primera vez, se describe y se diagnostica un fragmento de diente de mastodonte bunolofodonto procedente de la parte alta de la serie estratigráfica de este yacimiento. La morfología simplificada de las cúspides y las anchuras bucolinguales de las crestas y del talón la sitúan en la línea de los terceros molares de Tetralophodon (Falconer, 1857) de Polinyà (Vallés Occidental, Barcelona) y Crevillente (Bajo Vinalopó, Alicante). Por lo tanto, a partir de los datos morfométricos se identifica el material como un molar superior derecho deTetralophodon cf. longirostris (Kaup, 1832)
