RESUMEN

OBJECTIVE: To evaluate the association between therapeutic adherence and the phases of grief in patients with type 2 diabetes mellitus. DESIGN: Cross-sectional observational study. SITE: Family Medicine Unit No. 53 of the Mexican Institute of Social Security in the State of Guanajuato. PARTICIPANTS: A total of 354 patients with type 2 diabetes mellitus were recruited, of whom 236 corresponded to the group without therapeutic adherence and 118 to the group with therapeutic adherence. INTERVENTIONS: Two structured surveys were administered to both groups. MAIN MEASUREMENTS: The Morisky 8 scale was used to measure therapeutic adherence and the phases of grief scale (EFD-66) to measure grief due to loss of health. RESULTS: The median denial phase and depression phase scores were higher in the nonadherence group than in the adherence group (p=.000). The median negotiation phase and acceptance phase score was higher in the adherence group than in the nonadherence group (p=.000). Multivariate analysis identifies that denial is the main factor associated with non-adherence (OR=1.25; 95% CI: 1.14-1.37); while negotiation (OR=0.88; 95% CI: 0.82-0.94) and acceptance are associated with adherence (OR=0.79; 95% CI: 0.75-0.83). CONCLUSIONS: There is an association between therapeutic adherence and phases of grief.

RESUMEN

La diabetes mellitus tipo 1 (DM1) es una enfermedad autoinmune que genera dependencia exógena de insulina de forma permanente, presenta inflamación subclínica crónica lo que conlleva a una elevación de marcadores de inflamación como factor de necrosis tumoral alfa (TNF-α), proteína C reactiva (PCR) e interleuquina 6 (IL-6). OBJETIVO: determinar la relación entre el IMC sobre los marcadores de inflamación y el control metabólico en niños y jóvenes con DM1 entre 5 a 15 años de edad. METODOLOGÍA: Se realizó un estudio clínico, observacional, exploratorio. A partir de La recolección de datos de fichas clínicas y muestras de sangre en el Instituto de Investigaciones Materno Infantil (IDIMI) del Hospital San Borja Arriarán de la Universidad de Chile. Clasificación del estado nutricional utilizando datos registrados en ficha clínica. Marcadores de inflamación por medio de ELISA, hemoglobina glicosilada mediante métodos estándares. El análisis estadístico incluyó correlaciones mediante test de Spearman y diferencia de medias mediante test de Kruskal-Wallis seguido de post hoc Dunns. RESULTADOS: Un 30% de los pacientes con DM1 presentaron malnutrición por exceso. Al analizar la relación entre los niveles de marcadores inflamatorios y Hb glicosilada se observó la existencia de asociacion positiva entre usPCR y HbA1c (r= 0,30; p=0,0352) y entre IL-6 y HbA1c (r= - 0,038; p=0,0352). CONCLUSIONES: este estudio describe una posible asociación entre parámetros clásicos de inflamación con la hemoglobina glicosilada en las categorias de sobrepeso y obesidad en pacientes con DM1.


Type 1 diabetes mellitus (T1D) is an autoimmune disease that generates permanent exogenous insulin dependence, accompanied by chronic subclinical inflammation that leads to an elevation of inflammation markers such as tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP) and interleukin-6 (IL-6). OBJECTIVE: To determine the relationship between BMI on markers of inflammation and metabolic control in children and young people with T1D between 5 and 15 years of age. METHODOLOGY: A clinical, observational and exploratory study was carried out, based on the collection of data from clinical records and blood samples of children and adolescents with DM1 at the Instituto de Investigaciones Materno Infantil (IDIMI) of the Hospital San Borja Arriarán of the Universidad de Chile. Nutritional status, levels of inflammation markers and glycosylated hemoglobin were determined by standardized methods. Statistical analysis included correlations by Spearman test and mean difference by Kruskal-Wallis test followed by post hoc Dunns test. RESULTS: A total of 56 patients with T1D were analyzed, 30% of whom presented excess malnutrition. Those children or adolescents with obesity presented significantly higher usPCR levels compared to underweight patients or patients at risk of malnutrition (p=0.039). In addition, HbA1c levels were determined which were negatively associated with usPCR (r= 0.30; p=0.0352) and IL-6 (r= - 0.038; p=0.0352) levels. CONCLUSIONS: This study points out that nutritional status is associated with usPCR levels, in agreement with what is described in the literature and shows a possible association between classical parameters of inflammation with glycosylated hemoglobin in children and adolescents with nutritional diagnosis of overweight or obesity.

RESUMEN

In this eight-year retrospective study, we evaluated the associations between climatic variations and the biological rhythms in plasma lipids and lipoproteins in a large population of Campinas, São Paulo state, Brazil, as well as temporal changes of outcomes of cardiovascular hospitalizations. Climatic variables were obtained at the Center for Meteorological and Climatic Research Applied to Agriculture (University of Campinas - Unicamp, Brazil). The plasma lipid databases surveyed were from 27,543 individuals who had their lipid profiles assessed at the state university referral hospital in Campinas (Unicamp). The frequency of hospitalizations was obtained from the Brazilian Public Health database (DATASUS). Temporal statistical analyses were performed using the methods Cosinor or Friedman (ARIMA) and the temporal series were compared by cross-correlation functions. In normolipidemic cases (n=11,892), significantly different rhythmicity was observed in low-density lipoprotein (LDL)- and high-density lipoprotein (HDL)-cholesterol (C) both higher in winter and lower in summer. Dyslipidemia (n=15,651) increased the number and amplitude of lipid rhythms: LDL-C and HDL-C were higher in winter and lower in summer, and the opposite occurred with triglycerides. The number of hospitalizations showed maximum and minimum frequencies in winter and in summer, respectively. A coincident rhythmicity was observed of lower temperature and humidity rates with higher plasma LDL-C, and their temporal series were inversely cross-correlated. This study shows for the first time that variations of temperature, humidity, and daylight length were strongly associated with LDL-C and HDL-C seasonality, but moderately to lowly associated with rhythmicity of atherosclerotic outcomes. It also indicates unfavorable cardiovascular-related changes during wintertime.

RESUMEN

A 15-year-old, mixed breed, male horse was attended with a history of multiple abscesses in the cervical region with a three-year evolution. Upon admission, three fistulous tracts with drainage of purulent secretions in the cervical region, low body score, restriction of cervical movements, and painful sensitivity to palpation were observed. The horse was diagnosed with osteomyelitis secondary to Streptococcus equi infection. The initial treatment was antibiotic therapy and local curative. Owing to the lack of response, surgical debridement was performed. An initial favorable response was observed; however, after 4 months, drainage recurred, and the animal was euthanized. A post-mortem computed tomography scan was performed to obtain details of the injury. Cervical osteomyelitis is rare, and its occurrence through hematogenous spread in adult horses and the tomographic findings had not been reported previously. The long period of evolution, difficulty in performing an aggressive debridement, and the presence of multi-drug resistant bacteria contributed to the negative outcome.(AU)


Um equino macho, sem raça definida, de 15 anos de idade, foi atendido com histórico de múltiplos abscessos cervicais com evolução de três anos. Na admissão, foram observados: três trajetos fistulosos com drenagem de material purulento na região cervical; baixo escore corporal; restrição de movimentos cervicais; e sensibilidade dolorosa à palpação da região. Foi diagnosticada osteomielite vertebral cervical secundária à infecção por Streptococcus equi. O tratamento inicial consistiu na administração de antibióticos e curativo local. Na ausência de resposta à terapia, realizou-se o debridamento cirúrgico. Inicialmente, obteve-se uma resposta favorável, entretanto, após quatro meses, houve recidiva da lesão e o animal foi submetido à eutanásia. Realizou-se tomografia computadorizada no post mortem para detalhamento da lesão. A osteomielite vertebral cervical é rara, e sua ocorrência por meio de disseminação hematógena em animais adultos não foi previamente reportada. O longo período de evolução, aliado à dificuldade de realização de um debridamento agressivo, e a característica multirresistente do agente etiológico contribuíram para o desfecho negativo do caso.(AU)

RESUMEN

Resumen Introducción: Las personas que sufren un Evento Vascular Cerebral (EVC), generalmente quedan incapacitadas para la realización de sus actividades básicas, lo que conlleva a una dependencia. Por consiguiente, es importante la elaboración de un plan de egreso con amplia información sobre los cuidados que facilite al profesional de enfermería brindar educación para la salud, dirigida a familiares y enfermos sobre el cuidado en el hogar tras un EVC. Métodos: El procedimiento utilizado para esta propuesta constó de tres fases, en las cuales se realizó una revisión de la literatura, una delimitación con base en el tema central, para finalmente, elaborar el plan de egreso que aquí se presenta. Resultados: En la primera fase se analizaron 39 estudios, 16 de tipo cualitativo, 11 cuantitativos, ocho Guías de práctica clínica, tres mixtos y dos tesis; posteriormente, en la segunda fase se estableció la delimitación del tema con base en el criterio de evidencia científica y los diagnósticos enfermeros de la NANDA, y finalmente; en la tercera fase, se prescribieron las principales intervenciones de cuidado a implementar tras el egreso de pacientes con EVC. Discusión y conclusiones: El plan de egreso forma parte del cuidado integral y humanizado, requiere llevarse a cabo de forma habitual para facilitar el diálogo sobre las incertidumbres, dudas y angustias presentes, frecuentemente, en el cuidador primario y enfermo tras su egreso. A su vez, las guías de cuidado contribuyen a establecer el plan de egreso al enfermo, con el propósito de disminuir los reingresos hospitalarios, prevenir complicaciones y mejorar su calidad de vida, además de poder seguir innovando la práctica clínica de enfermería.


Abstract Introduction: Persons who suffer a stroke generally are not able to carry out their basic activities and thus become dependent. Because of this, designing discharge plans based on wide-scope information facilitating nursing staff provide healthcare education to victims of stroke and their families is of paramount importance. Methods: In the proposal three stages were considered: a literature review; a main topic delimitation; and a discharge plan, herein featured. Results: In the first stage, 39 studies were analyzed: 16 qualitative; 11 quantitative; 8 clinical practice guides; 3 mixed methods; and 2 dissertations. In the second stage, the main theme was established based on the scientific criteria and the NANDA nursing diagnostics. In the third stage, the main cerebrovascular disease care interventions were prescribed. Discussion and conclusions: The integral discharge plan requires being regularly carried out in order to foster dialogues on related uncertainties, doubts, and anxieties. These care guides can contribute to the establishment of discharge plans aimed at reducing hospital readmissions, preventing complications, and improving the quality of life of these patients.

RESUMEN

The follicle is a dynamic microenvironment in the ovary where the oocyte develops. Intercellular communication between somatic cells and the oocyte inside the follicle is essential to generate a competent gamete. Extracellular vesicles are nanoparticles secreted by cells that mediate cell-to-cell communication in the follicle microenvironment and can be obtained from the follicular fluid. These extracellular vesicles have been studied as biomarkers and supplementation tools to mimic physiological conditions during assisted reproductive techniques because they are vehicles of bioactive molecules. Therefore, this paper reviews the importance of changes in the ovarian follicle and the effects of extracellular vesicles from follicular fluid during oocyte maturation and early embryo development. Finally, we propose that is important to consider the source of the extracellular vesicles to improve diagnostic methods and to increase invitro embryo production.

RESUMEN

This study was performed in Ross 308 chickens aged 1-21 days and aimed to evaluate whether the addition of 25-hydroxycholecalciferol (25(OH)D3 ) to broiler chicken diets affects their growth performance and immunity. A completely random 2 × 2 factorial arrangement was used with two levels of vitamin D3 and the absence or presence of 25(OH)D3 , corresponding to four treatments based on sorghum + soya bean diets: (i) 200 IU of vitamin D3 /kg of feed (Diet 1) (NRC, ), (ii) Diet 1 + 69 µg of 25(OH)D3 /kg of feed (Diet 2), (iii) 5,000 IU of vitamin D3 /kg of feed (Diet 3) and (iv) Diet 3 + 69 µg of 25(OH)D3 /kg of feed (Diet 4). Each treatment was conducted with six replicates of 10 chickens each. Water and feed was supplied ad libitum. The results showed significantly increased growth and tibia ash (p < .05) in the birds fed 5,000, IU of vitamin D3 /kg + 25(OH)D3 . Additionally, the cellular immune response increased significantly (p < .05) in both treatments with added 25(OH)D3. Based on the results obtained under the current test conditions, the addition of 25(OH)D3 at a rate of 69 µg/kg to diets containing vitamin D3 improved the cellular immune response and mineral deposition in the bones of broilers aged 1-21 days. Because these parameters are very important in modern poultry farming, these results indicate that supplementation with 25(OH)D3 should improve broiler production.

RESUMEN

Nitrogen fertilization of deferred pastures increases the production of forage that will be used in winter, which benefits cattle farmers. The objective of this study was to evaluate the forage accumulation and canopy structure of Brachiaria brizantha cv. Marandu (marandu grass) during the deferment period in response to nitrogen fertilization. Two fertilization strategies of marandu grass were evaluated: fertilization with 200 kg N/ha divided into three applications at intervals of 30 days (two applications before and one at the beginning of the deferment period), and fertilization with a single dose of 50 kg N/ha at the beginning of the deferment period. A completely randomized design consisting of two treatments and four replicates was used. At the beginning of the deferment period, the structural characteristics of the marandu canopy did not differ between nitrogen doses. During the deferment period, the production of forage (P=0.0388), green leaf blade (P=0.0041) and green stem (P=0.0095) was higher for plants fertilized with 200 kg N/ha compared to those fertilized with 50 kg N/ha. The nitrogen doses did not influence leaf blade or stem senescence, with mean values of 1,497 and 1,432 kg dry matter/ha, respectively...


A adubação nitrogenada em pastos diferidos aumenta a produção de forragem que será utilizada na época de inverno, o que representa benefício para o pecuarista. Esse trabalho foi conduzido para avaliar o acúmulo de forragem e a estrutura dos dosséis de Brachiaria brizantha cv. Marandu (capim-marandu) durante o período de diferimento, em resposta à adubação nitrogenada. Foram avaliadas duas estratégias de adubação do capim-marandu: adubação de 200 kg/ha de N parcelada em três aplicações a cada 30 dias (duas aplicações antes e uma no início do período de diferimento) e adubação em dose única de 50 kg/ha de N no início do período de diferimento. O delineamento experimental utilizado foi o inteiramente casualizado, com dois tratamentos e quatro repetições. No início do período de diferimento, as características estruturais do dossel de capim-marandu não variaram entre as doses de nitrogênio. Durante o período de diferimento, as produções de forragem (P=0,0388), de lâmina foliar viva (P=0,0041) e de colmo vivo (P=0,0095) foram maiores nas plantas adubadas com 200 kg/ha de N do que naquelas adubadas com 50 kg/ha de N. A senescência da lâmina foliar e do colmo não foram influenciadas pelas doses de nitrogênio, com valores médios de 1497 e 1432 kg/ha de matéria seca, respectivamente...

RESUMEN

El despistaje de infecciones mediante pruebas de laboratorio permite disminuir el riesgo de morbimortalidad perinatales y maternas. El objetivo del estudio fue identificar la presencia de infecciones de transmisión vertical: toxoplasmosis, VIH, sífilis, Hepatitis B y C, durante el periodo noviembre 2013 a mayo 2014. Estudio descriptivo, muestra conformada por 175 embarazadas entre 14 a 43 años, a las cuales se les descarto Toxoplasmosis, Anticuerpos Reagínicos por VDRL cualitativa, VIH, hepatitis B (Anti-HBsAg, HBsAg, anti-Core); hepatitis C (Anticuerpos totales), a través de ultramicroELISA (UMELISA). Los resultados arrojaron Anticuerpos Anti Toxoplasma gondii positivas en 27,4%, donde el 31,2% de estas embarazadas presentaron títulos de anticuerpos de 1/512. Los Anticuerpos Anti-VIH resultaron positivos en 0,6%. El 99,4% mostraron un VDRL No Reactivo. El 38,9% tuvo un resultado positivo para anticuerpos contra el antígeno de superficie de la hepatitis B, los marcadores HBsAg y Anti-Core resultaron negativos en un 100%; el 1,7% fue positivo para anticuerpos totales contra el virus de la Hepatitis C. Se concluye que el despistaje de enfermedades infecciosas que representan factores de riesgo de transmisión vertical en embarazadas, constituye uno de los medios más oportuno para diagnosticar estas patologías y prevenir la morbimortalidad materna e infantil.


The screening for infection diseases in pregnancy by laboratory tests can reduce the risk of perinatal and maternal morbidity and mortality. The objective of this study was to identify the presence of vertically transmitted infections: toxoplasmosis, HIV, syphilis, hepatitis B and C, for the period November 2013 to May 2014. Descriptive study, the sample consisted of 175 pregnant women between 14 to 43 years, women who were discarded for Toxoplasmosis, Reaginic Antibodies by qualitative VDRL, HIV, hepatitis B (Anti-HBsAg Anti-HBsAg, anti-Core); hepatitis C (Total antibodies), through ultramicroELISA (UMELISA). The results showed 27.4% positive for Anti- Toxoplasma gondii antibodies, with 31.2% of these pregnant women having antibody titers of 1/512. Anti-HIV antibodies were positive by 0.6%. 99.4% showed Nonreactive VDRL. 38.9% were positive for antibodies against the hepatitis B surface antigen, the markers HBsAg and anti-Core were negative by 100%; 1.7% were positive for total antibodies against Hepatitis C. It is concluded that the screening of infectious diseases that represent risk factors for vertically transmission infections during pregnancy, is one of the most appropriate tools to diagnose these diseases and prevent maternal and infant morbidity and mortality.

RESUMEN

Wilson disease is an autosomal recessive disorder of the copper's hepatic metabolism; it results in toxicity due to accumulation of the mineral. The hemolytic anemia is present in 17% at some point of the disease, although it is a rare initial clinical presentation. CASE REPORT: 11 years old boy who presented with negative Coombs hemolytic anemia and elevation of liver enzymes. The possibility of Wilson disease was considered, which was confirmed with the finding of a Kayser-Fleischer ring in the eye exam. He also had a low ceruloplasmin level in plasma and a high urinary copper excretion. He was treated with D-penicillamine and pyridoxine.


La enfermedad de Wilson es una enfermedad hereditaria de tipo autosómico recesivo del metabolismo del cobre; produce toxicidad por la acumulación de este. La anemia hemolítica en la enfermedad de Wilson ocurre hasta en un 17% en algún momento de la enfermedad; sin embargo, es inusual como presentación inicial. Se expone un caso de enfermedad de Wilson en un niño de 11 años con anemia hemolítica, prueba de Coombs negativa y elevación de enzimas hepáticas. Se realizó un fondo de ojo, que mostró anillos de Kayser-Fleischer, junto con niveles bajos de ceruloplasmina y elevación en la excreción del cobre urinario. El paciente se trató con D-penicilamina y piridoxina.

RESUMEN

Climate change scenarios are computed on a large scale, not accounting for local variations presented in historical data and related to human scale. Based on historical records, we validate a baseline (1962-1990) and correct the bias of A2 and B2 regional projections for the end of twenty-first century (2070-2100) issued from a high resolution dynamical downscaled (using PRECIS mesoscale model, hereinafter DGF-PRECIS) of Hadley GCM from the IPCC 3rd Assessment Report (TAR). This is performed for the Araucanía Region (Chile; 37°-40°S and 71°-74°W) using two different bias correction methodologies. Next, we study high-resolution precipitations to find monthly patterns such as seasonal variations, rainfall months, and the geographical effect on these two scenarios. Finally, we compare the TAR projections with those from the recent Assessment Report 5 (AR5) to find regional precipitation patterns and update the Chilean `projection. To show the effects of climate change projections, we compute the rainfall climatology for the Araucanía Region, including the impact of ENSO cycles (El Niño and La Niña events). The corrected climate projection from the high-resolution dynamical downscaled model of the TAR database (DGF-PRECIS) show annual precipitation decreases: B2 (-19.19 %, -287 ± 42 mm) and A2 (-43.38 %, -655 ± 27.4 mm per year. Furthermore, both projections increase the probability of lower rainfall months (lower than 100 mm per month) to 64.2 and 72.5 % for B2 and A2, respectively.

RESUMEN

Background: Type 1 diabetes mellitus and celiac disease share common genetic and immunological aspects and celiac disease is more common among type 1 diabetic patients. Aim: To determine the frequency of anti endomysial and anti transglutaminase antibodies among patients with type 1 diabetes. Material and Methods: Anti endomysialantibodies determined by indirect immunofluorescence an anti transglutaminase antibodies determined by ELISA were measured in 410 serum samples of patients with type 1 diabetes. Results: Seventy one samples (17 percent) had positive anti transglutaminase antibodies. Among these, 17 had also positive anti endomysial antibodies. In 11 of these 17 patients, the presence of celiac disease was confirmed. Conclusions: Among patients with type 1 diabetes mellitus, the frequency of celiac disease is three times higher than in the general population.

RESUMEN

Neste estudo, 67 ejaculados foram avaliados, antes e depois da técnica de swim-up, em relação à qualidade seminal e à presença do CAEV. Das 67 amostras testadas por PCRn, antes do swim-up, 47 (70,15%) foram positivas para o DNA pró-viral. No entanto, quatro amostras adicionais foram positivas ao RT-nested PCR após o swim-up, o que permite dizer que, pelo menos, 76,12% (51/67) delas estavam infectadas antes da lavagem. Todavia, em 23,88% (16/67) das amostras não foi detectada a presença do CAEV. Após a aplicação da técnica de swim-up, constatou-se, pela PCRn e RT-nested PCR, que houve uma redução significativa (χ²= 9,078; p<0,001) da presença do CAEV nas amostras seminais, pois 28 de 51 amostras positivas resultaram livres do vírus (54,90%), tanto para DNA pró-viral quanto para o vírus livre. Em relação à motilidade individual progressiva (MIP) e vigor espermático obtidos antes e depois da técnica de swim-up, observou-se uma diminuição significativa em suas médias, sendo o MIP de 86,42% para 71,49%, já o vigor espermático de 4,16 para 3,93. Conclui-se que a eliminação do CAEV no sêmen é de caráter intermitente, e que a associação da PCRn e RT-nested PCR é uma opção segura para a certificação sanitária individual das amostras seminais quanto à presença ou ausência do CAEV. Finalmente, a técnica de swim-up promove uma redução na infectividade de amostras de sêmen contaminadas, e, além disso, é possível promover a recuperação de espermatozoides viáveis.


In this study, 67 ejaculates were assessed before and after the swim-up technique in relation to semen quality and presence of CAEV. Of the 67 samples tested by Nested PCR, before swim-up 47 (70.15%) were positive for viral DNA. Furthermore, four additional samples were positive for RT-nested PCR after swim-up, which allows us to affirm that at least 76.12% (51/67) were infected before washing. However, 23.88% (16/67) of the samples did not detect the presence of CAEV. After application of the swim-up technique it was found, by Nested PCR and RT-nested PCR, that there was a significant decrease (χ² = 9.078, p <0.001) in the presence of CAEV in semen samples, once 28 of 51 positive samples were free from the virus (54.90%) for both proviral DNA and the free form of the virus. Regarding individual progressive motility (IPM) and spermatic vigor obtained before and after the swim-up technique, a significant decrease was observed in the average, being 86.42% of the IPM to 71.49% and the spermatic vigor from 4.16 for the 3.93. It is concluded that the removal of CAEV in semen has an intermittent character, and the combination of PCR and RT-nested PCR is a safe option for health certification of individual semen samples for the presence or absence of CAEV. Finally, the swim-up technique promotes a reduction in the infectivity of contaminated semen samples, and it is possible to promote the recovery of high individual progressive motility sperm and sperm vigor.

RESUMEN

Plants interact with a myriad of microbial cells in the rhizosphere, an environment that is considered to be important for plant development. However, the differential structuring of rhizosphere microbial communities due to plant cultivation under differential agricultural practices remains to be described for most plant species. Here we describe the rhizosphere microbiome of grapevine cultivated under conventional and organic practices, using a combination of cultivation-independent approaches. The quantification of bacterial 16S rRNA and nifH genes, by quantitative PCR (qPCR), revealed similar amounts of these genes in the rhizosphere in both vineyards. PCR-DGGE was used to detect differences in the structure of bacterial communities, including both the complete whole communities and specific fractions, such as Alphaproteobacteria, Betaproteobacteria, Actinobacteria, and those harboring the nitrogen-fixing related gene nifH. When analyzed by a multivariate approach (redundancy analysis), the shifts observed in the bacterial communities were poorly explained by variations in the physical and chemical characteristics of the rhizosphere. These approaches were complemented by high-throughput sequencing (67,830 sequences) based on the V6 region of the 16S rRNA gene, identifying the major bacterial groups present in the rhizosphere of grapevines: Proteobacteria, Actinobacteria, Firmicutes, Bacteriodetes, Acidobacteria, Cloroflexi, Verrucomicrobia and Planctomycetes, which occur in distinct proportions in the rhizosphere from each vineyard. The differences might be related to the selection of plant metabolism upon distinct reservoirs of microbial cells found in each vineyard. The results fill a gap in the knowledge of the rhizosphere of grapevines and also show distinctions in these bacterial communities due to agricultural practices.
