Association Of Bartonella Species With Wild And Synanthropic Rodents In Different Brazilian Biomes
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.

Biologia reprodutiva de Talitroides topitotum (Burt) (Crustacea, Amphipoda, Talitridae) na Serra do Mar, Guaratuba, ParanĂĄ, Brasil
CaracterĂsticas morfomĂŠtricas de Talitroides topitotum (Burt) (Crustacea, Amphipoda, Talitridae) na Serra do Mar, Guaratuba, ParanĂĄ, Brasil Morphometric characteristics of Talitroides topitotum (Burt) (Crustacea, Amphipoda, Talitridae) from Serra do Mar, Guaratuba, ParanĂĄ, Brazil
Um estudo sobre as relaçþes morfomĂŠtricas entre o comprimento cefĂĄlico (Lc) e o comprimento total do corpo (Lt), e o nĂşmero de artĂculos 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 HidroelĂŠtrica de Guaricana, Guaratuba, ParanĂĄ. O objetivo foi auxiliar na inferĂŞncia do comprimento do corpo a partir do comprimento cefĂĄlico e da idade relativa dos exemplares pela contagem do nĂşmero de artĂculos de seus flagelos antenais. Um total de 975 exemplares foi coletado e fotografado, dos quais os artĂculos dos flagelos direito e esquerdo das antenas 1 e 2 foram contados e os comprimentos do segmento cefĂĄlico e do corpo foram medidos. Houve uma correlação linear entre o comprimento do segmento cefĂĄlico e o comprimento total do corpo definido pela equação Lc = 0,0506Lt + 0,3297; r² = 0,9577. Diferenças significativas foram observadas entre os nĂşmeros de artĂculos dos flagelos direito e esquerdo de ambas as antenas. A diferença foi de atĂŠ quatro artĂculos no primeiro par de antenas e de doze no segundo. O maior nĂşmero de artĂculos 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 possĂvel inferir o estĂĄgio relativo de desenvolvimento de T. topitotum pelas medidas do comprimento do segmento cefĂĄlico. Entretanto, somente o maior nĂşmero de artĂculos entre os flagelos direito e esquerdo constitui parâmetro de referĂŞncia para inferir a idade relativa dos indivĂduos desta espĂŠcie.<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, ParanĂĄ. 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
Results from Colombia's 2016 report card on physical activity for children and youth
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.
