This work reports the effects of the genetic makeup, the environment and the genotype by environment interactions for node addition rate in an RIL population of common bean. This information was used to build a predictive model for node addition rate. To select a plant genotype that will thrive in targeted environments it is critical to understand the genotype by environment interaction (GEI). In this study, multi-environment QTL analysis was used to characterize node addition rate (NAR, node day(- 1)) on the main stem of the common bean (Phaseolus vulgaris L)...

Marek's disease ( ) is a lymphoproliferative disease caused by an Alphaherpesvirus, genus Mardivirus , serotype 1 ( Gallid Herpesvirus 2 , GaHV-2) that includes all known pathogenic strains. In addition to Marek's disease virus ( ) serotype 1, the genus includes 2 distinct nonpathogenic serotypes: serotype 2 (GaHV-3) and serotype 3 ( Meleagridis Herpesvirus 1 , MeHV-1) which are used in commercially available vaccines against MD. As a result of vaccination, clinical signs are not commonly observed, and new cases are usually associated with emerging variant strains against which the vaccines are less effective...

The genus Avicularia Lamarck, 1818 is revised and all species are rediagnosed. The type species, described as Aranea avicularia Linnaeus, 1758, is the oldest mygalomorph species described and its taxonomic history is extensive and confusing. Cladistic analyses using both equal and implied weights were carried out with a matrix of 46 taxa from seven theraphosid subfamilies, and 71 morphological and ecological characters. The optimal cladogram found with Piwe and concavity = 6 suggests Avicularia and Aviculariinae are monophyletic...

The aim of the study was to discover cases of childhood leptospirosis in four municipalities in the region of Urabá (Colombia) and the factors related to the severity of clinical manifestations. A retrospective cross-sectional study assessed 74 children aged younger than 17 years with febrile syndrome due to leptospirosis between 2010 and 2012. The majority of cases were in children from urban areas (57/74; 77%), between 10 and 14 years of age (33/74; 44.5%). The microscopic agglutination test (MAT) revealed that the most frequent serogroups were Grippotyphosa and Bratislava, which are associated with wildlife and livestock reservoirs, respectively...

Zika virus (ZIKV) disease outbreaks occurred in French Polynesia in 2013-2014 and in Brazil and Colombia in 2015-2016, respectively. Using our recently developed ZIKV disease model, we simulated the reported ZIKV infection cases from French Polynesia, Colombia and the State of Bahia of Brazil. Moreover, we estimated that the infection attack rates were 78.0% (95% confidence interval (CI): 63.5-86.3%) in French Polynesia which closely matches a previous serological study; 20.8% (95% CI: 1.1-50.0%) in Colombia which suggests that the attack rate was most likely less than 50%; and 32...

Young wives in South Korea often dread New Year's Day and Thanksgiving Day because they assume the burden of cooking, cleaning, and other household chores. We used their offspring's birthweight as an indicator of their stress levels. We included all Korean singletons born in hospitals during 1997-2014 (N = 8,589,426) and regressed birthweight on in utero holiday experience by trimester, along with covariates. Babies who experienced New Year's Day in the first trimester were 9.4 grams lighter than those who did not; the amount is equivalent to 120% of the reduced birthweight associated with experiencing landmine explosions during the first trimester in Colombia...

Drought is the major abiotic stress factor limiting yield of common bean (Phaseolus vulgaris L.) in smallholder systems in Latin America and eastern and southern Africa; where it is a main source of protein in the daily diet. Identification of shoot and root traits associated with drought resistance contributes to improving the process of designing bean genotypes adapted to drought. Field and greenhouse studies were conducted at the International Center for Tropical Agriculture (CIAT), Palmira, Colombia to determine the relationship between grain yield and different shoot and root traits using a recombinant inbred lines (RILs) population (MD23-24 × SEA 5) of common bean...

Snake venom phospholipases A2 (PLA2) share high sequence identities and a conserved structural scaffold, but show important functional differences. Only a few PLA2s have been purified and characterized from coral snake (Micrurus spp.) venoms, and their role in envenomation remains largely unknown. In this report, we describe the isolation, sequencing and partial functional characterization of two Micrurus PLA2s: MmipPLA2 from Micrurus mipartitus and MdumPLA2 from Micrurus dumerilii, two species of clinical importance in Colombia...

Alveiro Salamanca-Jimenez, Timothy A Doane, William R Horwath
Nitrogen (N) is the most limiting nutrient for coffee production in Colombia. An adequate supply is especially important during the vegetative period of growth, since any deficiency during this short period is known to have lasting effects on subsequent coffee bean production. Urea fertilizer is commonly applied on the soil surface since steep slopes hamper incorporation into soil, a practice which increases the risk of N volatilization. Little information is available on N recovery during early growth stages under different fertilizer application practices...

In Colombia, Bothrops asper is responsible for 70-90% of ophidians accidents reported annually. Envenoming occurs mainly in rural areas where both antivenom and health centers are scarce. Thus, patients are frequently treated by local healers that employ medicinal herbs; including several species belonging to Dracontium genus. In this work, we evaluated the neutralizing activity of Dracontium dubium Kunth against the lethal, inflammatory, coagulant and hemolytic effects produced by B. asper venom. Mice treated with D...

OBJECTIVE Diagnosing nosocomial meningitis (NM) in neurosurgical patients is difficult. The standard CSF test is not optimal and when it is obtained, CSF cultures are negative in as many as 70% of cases. The goal of this study was to develop a diagnostic prediction rule for postoperative meningitis using a combination of clinical, laboratory, and CSF variables, as well as risk factors (RFs) for CNS infection. METHODS A cross-sectional study was performed in 4 intensive care units in Medellín, Colombia. Patients with a history of neurosurgical procedures were selected at the onset of febrile symptoms and/or after an increase in acute-phase reactants...

Helicobacter pylori (HP) genetics may determine its clinical outcomes. Despite high prevalence of HP infection in Latin America (LA), there have been no phylogenetic studies in the region. We aimed to understand the structure of HP populations in LA mestizo individuals, where gastric cancer incidence remains high. The genome of 107 HP strains from Mexico, Nicaragua and Colombia were analyzed with 59 publicly available worldwide genomes. To study bacterial relationship on whole genome level we propose a virtual hybridization technique using thousands of high-entropy 13 bp DNA probes to generate fingerprints...
