    Bartonella spp. comprise an ecologically successful group of microorganisms that infect erythrocytes and have adapted to different hosts, which include a wide range of mammals, besides humans. Rodents are reservoirs of about two-thirds of Bartonella spp. described to date; and some of them have been implicated as causative agents of human diseases. In our study, we performed molecular and phylogenetic analyses of Bartonella spp. infecting wild rodents from five different Brazilian biomes. In order to characterize the genetic diversity of Bartonella spp., we performed a robust analysis based on three target genes, followed by sequencing, Bayesian inference, and maximum likelihood analysis. Bartonella spp. were detected in 25.6% (117/457) of rodent spleen samples analyzed, and this occurrence varied among different biomes. The diversity analysis of gltA sequences showed the presence of 15 different haplotypes. Analysis of the phylogenetic relationship of gltA sequences performed by Bayesian inference and maximum likelihood showed that the Bartonella species detected in rodents from Brazil was closely related to the phylogenetic group A detected in other cricetid rodents from North America, probably constituting only one species. Last, the Bartonella species genogroup identified in the present study formed a monophyletic group that included Bartonella samples from seven different rodent species distributed in three distinct biomes. In conclusion, our study showed that the occurrence of Bartonella bacteria in rodents is much more frequent and widespread than previously recognized. Š 2016, American Society for Microbiology.

    Um estudo sobre as relaçþes morfomÊtricas entre o comprimento cefålico (Lc) e o comprimento total do corpo (Lt), e o número de artículos do flagelo do primeiro e segundo pares de antenas e o comprimento total do corpo foi realizado em uma população de Talitroides topitotum (Burt, 1934), no entorno da Usina HidroelÊtrica de Guaricana, Guaratuba, Paranå. O objetivo foi auxiliar na inferência do comprimento do corpo a partir do comprimento cefålico e da idade relativa dos exemplares pela contagem do número de artículos de seus flagelos antenais. Um total de 975 exemplares foi coletado e fotografado, dos quais os artículos dos flagelos direito e esquerdo das antenas 1 e 2 foram contados e os comprimentos do segmento cefålico e do corpo foram medidos. Houve uma correlação linear entre o comprimento do segmento cefålico e o comprimento total do corpo definido pela equação Lc = 0,0506Lt + 0,3297; r² = 0,9577. Diferenças significativas foram observadas entre os números de artículos dos flagelos direito e esquerdo de ambas as antenas. A diferença foi de atÊ quatro artículos no primeiro par de antenas e de doze no segundo. O maior número de artículos entre os dois flagelos mostrou uma correlação com a distribuição das classes de comprimento total do corpo com a equação a1 = 4,3463Lt0,4264 para o primeiro par de antenas, e a2 = 10,5700Lt0,3581 para o segundo par. Foi possível inferir o estågio relativo de desenvolvimento de T. topitotum pelas medidas do comprimento do segmento cefålico. Entretanto, somente o maior número de artículos entre os flagelos direito e esquerdo constitui parâmetro de referência para inferir a idade relativa dos indivíduos desta espÊcie.<br>A research on the relationship between the cephalic segment length (Lc) and total body length (Lt), and between the number of articles in the antenna flagellum and the total body length was conducted in a population of the terrestrial amphipod Talitroides topitotum (Burt, 1934) from Serra do Mar, Guaratuba, Paranå. It aimed to help the inference of the body length by measuring only the cephalic segment, and to know the relative age of individuals by counting the number of articles in their antenna flagellum. A total of 975 amphipods were caught with Malaise nets; they were photographed, the article number of the flagellum of the right and left antennae 1 and 2 was counted and cephalic segment length and their total body length was taken. There was a linear correlation between cephalic segment length and total body length defined through the equation Lc = 0.0506Lt + 0.3297; r² = 0.9577. There was a significant difference in the article number between the right and left flagellum, for both pairs of antennae. The difference was at most four articles for the fist antenna pair and twelve articles for the second one. The highest number of these articles between right and left flagellum showed a linear correlation with the total body length classes and it was expressed by the equation a1 = 4.3463Lt0.4264 for the first pair of antenna, and a2 = 10.5700Lt0.3581 for the second pair. I was possible to infer the relative stage of development of T. topitotum by measuring the cephalic segment length. However, only the highest number of articles between right and left flagellum constitutes a reference parameter for the inference of individual relative age in this species

    Background: Physical activity (PA) is vital to the holistic development of young people. Regular participation in PA is associated with substantial benefits for health, cognitive function, and social inclusion. Recognizing the potential of PA in the context of the current peace process in Colombia, the purpose of this article is to present the methodology and results of Colombia's second Report Card on PA for children and youth. Methods: A group of experts on PA graded 14 PA indicators based on data from national surveys and policy documents. Results: National and departmental policy indicators received a grade of B, while organized sport participation, overweight, obesity, community influence, and nongovernment initiatives indicators received a grade of C. Overall PA levels, active transportation, sedentary behaviors, and school influence received a grade of D. Active play, low physical fitness, and family influence received an Incomplete grade. Conclusion: PA levels are low and sedentary behaviors are high in Colombian children and youth, with notable geographic differences. A broad policy framework translated into specific actions could provide unique opportunities to bridge the gap between knowledge and practice, and contribute to social integration goals in a postconflict setting.
