Mayaro Virus Infection in Amazonia: A Multimodel Inference Approach to Risk Factor Assessment

Background: Arboviral diseases are major global public health threats. Yet, our understanding of infection risk factors is, with a few exceptions, considerably limited. A crucial shortcoming is the widespread use of analytical methods generally not suited for observational data - particularly null hypothesis-testing (NHT) and step-wise regression (SWR). Using Mayaro virus (MAYV) as a case study, here we compare information theory-based multimodel inference (MMI) with conventional analyses for arboviral infection risk factor assessment. Methodology/Principal Findings: A cross-sectional survey of anti-MAYV antibodies revealed 44% prevalence (n = 270 subjects) in a central Amazon rural settlement. NHT suggested that residents of village-like household clusters and those using closed toilet/latrines were at higher risk, while living in non-village-like areas, using bednets, and owning fowl, pigs or dogs were protective. The "minimum adequate" SWR model retained only residence area and bednet use. Using MMI, we identified relevant covariates, quantified their relative importance, and estimated effect-sizes (beta +/- SE) on which to base inference. Residence area (beta(Village) = 2.93 +/- 0.41; beta(Upland) = -0.56 +/- 0.33, beta(Riverbanks) = -2.37 +/- 0.55) and bednet use (beta = -0.95 +/- 0.28) were the most important factors, followed by crop-plot ownership (beta = 0.39 +/- 0.22) and regular use of a closed toilet/latrine (beta = 0.19 +/- 0.13); domestic animals had insignificant protective effects and were relatively unimportant. The SWR model ranked fifth among the 128 models in the final MMI set. Conclusions/Significance: Our analyses illustrate how MMI can enhance inference on infection risk factors when compared with NHT or SWR. MMI indicates that forest crop-plot workers are likely exposed to typical MAYV cycles maintained by diurnal, forest dwelling vectors; however, MAYV might also be circulating in nocturnal, domestic-peridomestic cycles in village-like areas. This suggests either a vector shift (synanthropic mosquitoes vectoring MAYV) or a habitat/habits shift (classical MAYV vectors adapting to densely populated landscapes and nocturnal biting); any such ecological/adaptive novelty could increase the likelihood of MAYV emergence in Amazonia.

The legs: a key to bird evolutionary success

Birds are the most diverse and largest group of extant tetrapods. They show marked variability, yet much of this variation is superficial and due to feather and bill color and shape. Under the feathers, the skeleto-muscular system is rather constant throughout the bird group. The adaptation to flight is the explanation for this uniformity. The more obvious morphological adaptations for flight are the wings, but the trunk is always rigid, the tail is short and the neck is flexible, since all these features are correlated with flying behaviour. Unrelated to the exigencies of flight, the legs always have three long bones, and all the birds walk on their toes. This leg structure is a striking plesiomorphic feature that was already present in related dinosaurs. The multi-purpose potential of the legs is the result of the skeletal architecture of a body with three segmented flexed legs. This configuration provides mechanical properties that allow the use of the legs as propulsive, paddling, foraging or grooming tools. It is the association of diverse modes of locomotion-walking, running, hopping, flying and swimming-that have enabled the birds to colonize almost all the environments on Earth.

Emergence of enteric viruses in production chickens is a concern for avian health

Several viruses have been identified in recent years in the intestinal contents of chickens and turkeys with enteric problems, which have been observed in commercial farms worldwide, including Brazil. Molecular detection of these viruses in Brazil can transform to a big threat for poultry production due to risk for intestinal integrity. This disease is characterized by severely delayed growth, low uniformity, lethargy, watery diarrhea, delayed feed consumption, and a decreased conversion rate. Chicken astrovirus (CAstV), rotavirus, reovirus, chicken parvovirus (ChPV), fowl adenovirus of subgroup I (FAdV-1), and avian nephritis virus (ANV) were investigated using the conventional polymerase chain reaction (PCR) and the reverse transcription polymerase chain reaction (RT-PCR). In addition, the infectious bronchitis virus (IBV), which may play a role in enteric disease, was included. The viruses most frequently detected, either alone or in concomitance with other viruses, were IBV, ANV, rotavirus, and CAstV followed by parvovirus, reovirus, and adenovirus. This study demonstrates the diversity of viruses in Brazilian chicken flocks presenting enteric problems characterized by diarrhea, growth retard, loss weight, and mortality, which reflects the multicausal etiology of this disease

Von der geographischen Analyse über die Bestandsaufnahme der anzutreffenden Krankheiten und der Anwendung traditioneller Medizin zu einem geomedizinischen Informationssystem am Beispiel einer Bergregion im Kabupaten Sikka (Insel Flores, Indonesien)

Im Rahmen der interdisziplinären Zusammenarbeit zur Durchsetzung des »Menschenrecht Gesundheit« wurde ein geomedizinisches Informationssystem erstellt, das auf die nordexponierten Bergdörfer zwischen 350 m ü. NN und 450 m ü. NN des Kabupaten Sikka auf der Insel Flores in Indonesien anwendbar ist. Es wurde eine Analyse der Zeit-Raum-Dimension der Gesundheitssituation in Wololuma und Napun Lawan - exemplarisch für die nordexponierten Bergdörfer - durchgeführt. Im Untersuchungsraum wurden Gesundheitsgefahren und Gesundheitsrisiken analysiert, Zonen der Gefahren herausgearbeitet und Risikoräume bewertet. Trotz eines El Niño-Jahres waren prinzipielle Bezüge der Krankheiten zum jahreszeitlichen Rhythmus der wechselfeuchten Tropen zu erkennen. Ausgehend von der Vermutung, dass Krankheiten mit spezifischen Klimaelementen korrelieren, wurden Zusammenhänge gesucht. Für jede Krankheit wurden Makro-, Meso- und Mikrorisikoräume ermittelt. Somit wurden Krankheitsherde lokalisiert. Die Generalisierung des geomedizinischen Informationssystems lässt sich auf der Makroebene auf die nordexponierten Bergdörfer zwischen 350 m ü. NN und 450 m ü. NN des Kabupaten Sikka übertragen. Aus einer Vielzahl von angetroffenen Krankheiten wurden sechs Krankheiten selektiert. Aufgrund der Häufigkeitszahlen ergibt sich für das Gesundheitsrisiko der Bevölkerung eine Prioritätenliste:rn- Dermatomykosen (ganzjährig)rn- Typhus (ganzjährig)rn- Infektionen der unteren Atemwege (Übergangszeit)rn- Infektionen der oberen Atemwege (Übergangszeit)rn- Malaria (Regenzeit)rn- Struma (ganzjährig)rnDie Hauptrisikogruppe der Makroebene ist die feminine Bevölkerung. Betroffen sind weibliche Kleinkinder von null bis sechs Jahren und Frauen ab 41 Jahren. Die erstellten Karten des zeitlichen und räumlichen Verbreitungsmusters der Krankheiten und des Zugangs zu Gesundheitsdienstleistungen dienen Entscheidungsträgern als Entscheidungshilfe für den Einsatz der Mittel zur Primärprävention. Die Geographie als Wissenschaft mit ihren Methoden und dem Zeit-Raum-Modell hat gezeigt, dass sie die Basis für die interdisziplinäre Forschung darstellt. Die interdisziplinäre Zusammenarbeit zur Gesundheitsforschung im Untersuchungszeitraum 2009 hat sich bewährt und muss weiter ausgebaut werden. Die vorgeschlagenen Lösungsmöglichkeiten dienen der Minimierung des Gesundheitsrisikos und der Gesundheitsvorsorge. Da die Systemzusammenhänge der Ätiologie der einzelnen Krankheiten sehr komplex sind, besteht noch immer sehr großer Forschungsbedarf. rnDas Ergebnis der vorliegenden Untersuchung zeigt, dass Wasser in jeder Form die primäre Ursache für das Gesundheitsrisiko der Bergdörfer im Kabupaten Sikka auf der Insel Flores in Indonesien ist.rnDer Zugang zu Wasser ist unerlässlich für die Verwirklichung des »Menschenrecht Gesundheit«. Das Recht auf Wasser besagt, dass jeder Mensch Zugang zu nicht gesundheitsgefährdendem, ausreichendem und bezahlbarem Wasser haben soll. Alle Staaten dieser Erde sollten sich dieser Forderung verpflichtet fühlen.rn

Harmonised monitoring of antimicrobial resistance in Salmonella and Campylobacter isolates from food animals in the European Union

Many Member States of the European Union (EU) currently monitor antimicrobial resistance in zoonotic agents, including Salmonella and Campylobacter. According to Directive 2003/99/EC, Member States shall ensure that the monitoring provides comparable data on the occurrence of antimicrobial resistance. The European Commission asked the European Food Safety Authority to prepare detailed specifications for harmonised schemes for monitoring antimicrobial resistance. The objective of these specifications is to lay down provisions for a monitoring and reporting scheme for Salmonella in fowl (Gallus gallus), turkeys and pigs, and for Campylobacter jejuni and Campylobacter coli in broiler chickens. The current specifications are considered to be a first step towards a gradual implementation of comprehensive antimicrobial resistance monitoring at the EU level. These specifications propose to test a common set of antimicrobial agents against available cut-off values and a specified concentration range to determine the susceptibility of Salmonella and Campylobacter. Using isolates collected through programmes in which the sampling frame covers all epidemiological units of the national production, the target number of Salmonella isolates to be included in the antimicrobial resistance monitoring per Member State per year is 170 for each study population (i.e., laying hens, broilers, turkeys and slaughter pigs). The target number of Campylobacter isolates to be included in the antimicrobial resistance monitoring per Member State per year is 170 for each study population (i.e., broilers). The results of the antimicrobial resistance monitoring are assessed and reported in the yearly national report on trends and sources of zoonoses, zoonotic agents and antimicrobial resistance.

Pretreatment of mice with streptomycin provides a Salmonella enterica serovar Typhimurium colitis model that allows analysis of both pathogen and host.

Salmonella enterica subspecies 1 serovar Typhimurium is a principal cause of human enterocolitis. For unknown reasons, in mice serovar Typhimurium does not provoke intestinal inflammation but rather targets the gut-associated lymphatic tissues and causes a systemic typhoid-like infection. The lack of a suitable murine model has limited the analysis of the pathogenetic mechanisms of intestinal salmonellosis. We describe here how streptomycin-pretreated mice provide a mouse model for serovar Typhimurium colitis. Serovar Typhimurium colitis in streptomycin-pretreated mice resembles many aspects of the human infection, including epithelial ulceration, edema, induction of intercellular adhesion molecule 1, and massive infiltration of PMN/CD18(+) cells. This pathology is strongly dependent on protein translocation via the serovar Typhimurium SPI1 type III secretion system. Using a lymphotoxin beta-receptor knockout mouse strain that lacks all lymph nodes and organized gut-associated lymphatic tissues, we demonstrate that Peyer's patches and mesenteric lymph nodes are dispensable for the initiation of murine serovar Typhimurium colitis. Our results demonstrate that streptomycin-pretreated mice offer a unique infection model that allows for the first time to use mutants of both the pathogen and the host to study the molecular mechanisms of enteric salmonellosis.

Characterization of serum amyloid A protein mRNA expression and secondary amyloidosis in the domestic duck

Secondary amyloidosis is a common disease of water fowl and is characterized by the deposition of extracellular fibrils of amyloid A (AA) protein in the liver and certain other organs. Neither the normal role of serum amyloid A (SAA), a major acute phase response protein, nor the causes of secondary amyloidosis are well understood. To investigate a possible genetic contribution to disease susceptibility, we cloned and sequenced SAA cDNA derived from livers of domestic ducks. This revealed that the three C-terminal amino acids of SAA are removed during conversion to insoluble AA fibrils. Analysis of SAA cDNA sequences from several animals identified a distinct genetic dimorphism that may be relevant to susceptibility to secondary amyloid disease. The duck genome contained a single copy of the SAA gene that was expressed in liver and lung tissue of ducklings, even in the absence of induction of acute phase response. Genetic analysis of heterozygotes indicated that only one SAA allele is expressed in livers of adult birds. Immunofluorescence staining of livers from adult ducks displaying early symptoms of amyloidosis revealed what appear to be amyloid deposits within hepatocytes that are expressing unusually high amounts of SAA protein. This observation suggests that intracellular deposition of AA may represent an early event during development of secondary amyloidosis in older birds.

Role of the cystic fibrosis transmembrane conductance regulator in innate immunity to Pseudomonas aeruginosa infections

Chronic Pseudomonas aeruginosa infection occurs in 75–90% of patients with cystic fibrosis (CF). It is the foremost factor in pulmonary function decline and early mortality. A connection has been made between mutant or missing CF transmembrane conductance regulator (CFTR) in lung epithelial cell membranes and a failure in innate immunity leading to initiation of P. aeruginosa infection. Epithelial cells use CFTR as a receptor for internalization of P. aeruginosa via endocytosis and subsequent removal of bacteria from the airway. In the absence of functional CFTR, this interaction does not occur, allowing for increased bacterial loads in the lungs. Binding occurs between the outer core of the bacterial lipopolysaccharide and amino acids 108–117 in the first predicted extracellular domain of CFTR. In experimentally infected mice, inhibiting CFTR-mediated endocytosis of P. aeruginosa by inclusion in the bacterial inoculum of either free bacterial lipopolysaccharide or CFTR peptide 108–117 resulted in increased bacterial counts in the lungs. CFTR is also a receptor on gastrointestinal epithelial cells for Salmonella enterica serovar Typhi, the etiologic agent of typhoid fever. There was a significant decrease in translocation of this organism to the gastrointestinal submucosa in transgenic mice that are heterozygous carriers of a mutant ΔF508 CFTR allele, suggesting heterozygous CFTR carriers may have increased resistance to typhoid fever. The identification of CFTR as a receptor for bacterial pathogens could underlie the biology of CF lung disease and be the basis for the heterozygote advantage for carriers of mutant alleles of CFTR.

Highly plastic chromosomal organization in Salmonella typhi.

Gene order in the chromosomes of Escherichia coli K-12 and Salmonella typhimurium LT2, and in many other species of Salmonella, is strongly conserved, even though the genera diverged about 160 million years ago. However, partial digestion of chromosomal DNA of Salmonella typhi, the causal organism of typhoid fever, with the endonuclease I-CeuI followed by separation of the DNA fragments by pulsed-field gel electrophoresis showed that the chromosomes of independent wild-type isolates of S. typhi are rearranged due to homologous recombination between the seven rrn genes that code for ribosomal RNA. The order of genes within the I-CeuI fragments is largely conserved, but the order of the fragments on the chromosome is rearranged. Twenty-one different orders of the I-CeuI fragments were detected among the 127 wild-type strains we examined. Duplications and deletions were not found, but transpositions and inversions were common. Transpositions of I-CeuI fragments into sites that do not change their distance from the origin of replication (oriC) are frequently detected among the wild-type strains, but transpositions that move the fragments much further from oriC were rare. This supports the gene dosage hypothesis that genes at different distances from oriC have different gene dosages and, hence, different gene expression, and that during evolution genes become adapted to their specific location; thus, cells with changes in gene location due to transpositions may be less fit. Therefore, gene dosage may be one of the forces that conserves gene order, although its effects seem less strong in S. typhi than in other enteric bacteria. However, both the gene dosage and the genomic balance hypotheses, the latter of which states that the origin (oriC) and terminus (TER) of replication must be separated by 180 degrees C, need further investigation.

La biodiversidad marina en la Región de Murcia

Actualmente se ha detectado la existencia de un gradiente de biodiversidad, marcado por el eje Nor-Oeste/Sur-Este y justificado por variables ambientales claves como la latitud, salinidad, temperatura, circulación de las masas de agua, etc. La conjunción de estas variables hacen del litoral de Murcia una de las zonas de mayor biodiversidad del Mediterráneo, mar ya de por sí caracterizado por una alta biodiversidad. Una de las singularidades paisajísticas del litoral murciano son los cañones submarinos cercanos a la línea de costa, propuestos en la Cumbre Mundial de Desarrollo Sostenible de Johannesburgo (2002) como hábitats únicos de gran importancia ecológica. La disposición geográfica del litoral murciano lo convierte en una pantalla que frena el agua procedente del Atlántico y que pasa por Gibraltar, configurando un espacio marino en el que convergen especies mediterráneas y atlánticas, tanto a nivel pelágico como nerítico. La Región de Murcia muestra una gran cantidad de hábitats marinos contenidos en la Lista Patrón de Hábitats Marinos presentes en España, pero si existe un hábitat emblemático en el medio marino mediterráneo y, por ende, en el litoral de la Región de Murcia, es el generado por las praderas de Posidonia oceanica (Posidonietum oceanicae). Otro importantísimo valor natural regional es la laguna salada del Mar Menor, hábitat prioritario de la Directiva Hábitats, que alberga importantes poblaciones de caballito de mar, langostinos y otras especies de interés, además de ser un importante lugar de paso e invernada de aves acuáticas, limícolas y marinas.

European banking disunion. CEPS Commentary, 14 November 2013

In this CEPS Commentary Daniel Gros argues that the purpose of the euro was to create fully integrated financial markets; but, since the start of the financial crisis in 2008, markets have increasingly separated along national lines. So the future of the eurozone depends crucially on whether that trend continues or is reversed and Europe’s financial markets in the end become fully integrated. But either outcome would be preferable to something in between – neither fish nor fowl. Unfortunately, that is where the eurozone appears to be headed.
