chikungunya outbreak in atmakur village, medak district, telangana state, india. 026905235
assessment of blood collection from the lateral saphenous vein for microfilaria counts in mongolian gerbils (meriones unguiculatus) infected with brugia pahangi.the nih guidelines for survival bleeding of mice and rats note that using the retroorbital plexus has a greater potential for complications than do other methods of blood collection and that this procedure should be performed on anesthetized animals. lateral saphenous vein puncture has a low potential for complications and can be performed without anesthesia. mongolian gerbils (meriones unguiculatus) are the preferred rodent model for filarial parasite research. to monitor microfilaria counts in ...026678366
primary dengue haemorrhagic fever in patients from northeast of brazil is associated with high levels of interferon-β during acute phase.dengue is an acute febrile disease caused by the mosquito-borne dengue virus (denv) that according to clinical manifestations can be classified as asymptomatic, mild or severe dengue. severe dengue cases have been associated with an unbalanced immune response characterised by an over secretion of inflammatory cytokines. in the present study we measured type i interferon (ifn-i) transcript and circulating levels in primary and secondary denv infected patients. we observed that dengue fever (df) a ...027223651
global distribution and environmental suitability for chikungunya virus, 1952 to 2015.chikungunya fever is an acute febrile illness caused by the chikungunya virus (chikv), which is transmitted to humans by aedes mosquitoes. although chikungunya fever is rarely fatal, patients can experience debilitating symptoms that last from months to years. here we comprehensively assess the global distribution of chikungunya and produce high-resolution maps, using an established modelling framework that combines a comprehensive occurrence database with bespoke environmental correlates, inclu ...027239817
quantification of ortholog losses in insects and vertebrates.the increasing number of sequenced insect and vertebrate genomes of variable divergence enables refined comparative analyses to quantify the major modes of animal genome evolution and allows tracing of gene genealogy (orthology) and pinpointing of gene extinctions (losses), which can reveal lineage-specific traits.018021399
inferring genome-scale rearrangement phylogeny and ancestral gene order: a drosophila case study.a simple, fast, and biologically inspired computational approach for inferring genome-scale rearrangement phylogeny and ancestral gene order has been developed. this has been applied to eight drosophila genomes. existing techniques are either limited to a few hundred markers or a small number of taxa. this analysis uses over 14,000 genomic loci and employs discrete elements consisting of pairs of homologous genetic elements. the results provide insight into evolutionary chromosomal dynamics and ...017996033
the significance of ratios of detritus types and micro-organism productivity to competitive interactions between aquatic insect detritivores.investigations of competitive interactions emphasize non-detrital resources, even though detritus is a major component of most food webs. studies of competing species focus usually on single resource types, although consumers in nature are likely to encounter mixtures of resource types that may affect whether competition results in exclusion or coexistence. the invasive mosquito aedes albopictus is capable of excluding the native mosquito ochlerotatus triseriatus in competition for single detrit ...017922707
surprising complexity of the ancestral apoptosis network.apoptosis, one of the main types of programmed cell death, is regulated and performed by a complex protein network. studies in model organisms, mostly in the nematode caenorhabditis elegans, identified a relatively simple apoptotic network consisting of only a few proteins. however, analysis of several recently sequenced invertebrate genomes, ranging from the cnidarian sea anemone nematostella vectensis, representing one of the morphologically simplest metazoans, to the deuterostomes sea urchin ...017958905
dengue fever seroprevalence and risk factors, texas-mexico border, 2004.reported autochthonous dengue fever transmission in the united states has been limited to 5 south texas border counties since 1980. we conducted a cross-sectional serosurvey in brownsville, texas, and matamoros, tamaulipas, mexico (n = 600), in 2004 to assess dengue seroprevalence. recent dengue infection was detected in 2% (95% confidence interval [ci] 0.5%-3.5%) and 7.3% (95% ci 4.3%-10.3%) of residents in brownsville and matamoros, respectively. past infection was detected in 40% (95% ci 34%- ...018257990

genomic mapping of suppressor of hairy-wing binding sites in drosophila.insulator elements are proposed to play a key role in the organization of the regulatory architecture of the genome. in drosophila, one of the best studied is the gypsy retrotransposon insulator, which is bound by the suppressor of hairy-wing (su [hw]) transcriptional regulator. immunolocalization studies suggest that there are several hundred su(hw) sites in the genome, but few of these endogenous su(hw) binding sites have been identified.017705839

the incubation period of yellow fever in the mosquito.1. the yellow fever virus was found in infectious form in aedes aegypti throughout the entire period of the extrinsic incubation, as demonstrated by the injection of the bodies of mosquitoes into normal rhesus monkeys at daily intervals after the insects had fed on an infected animal. 2. the virus was transmitted through the bite of the mosquitoes, in one experiment on and after the 9th day, and in two experiments on the 12th day after the initial infecting feed. 3. the pathologic changes produc ...192819869467
possibility of hereditary transmission of yellow fever virus by aedes aegypti (linn.).attempts to obtain passage of yellow fever virus from one generation to the next in a. aegypti were unsuccessful. subcutaneous injections at varying intervals of a saline emulsion of 200 eggs laid by an infective lot of mosquitoes produced no reaction in six normal m. rhesus monkeys. negative results were also obtained in five biting and two injection experiments with progeny of the same infective lot of mosquitoes in which seven normal monkeys were used. the eggs consisted of batches laid after ...192919869656
the filtrability of yellow fever virus as existing in the mosquito.the virus of yellow fever as it exists in aëdes aegypti mosquitoes, both in their so-called infective stage and in the intermediate condition termed the "incubation period", is capable of passing through berkefeld n filters when suspended in normal monkey serum, although earlier investigators have shown that the virus from infective mosquitoes will not do so when suspended in physiological salt solution. the virus of yellow fever as it exists in mosquitoes behaves with regard to filtration throu ...192919869658
studies on yellow fever in south america : iv. transmission experiments with aedes aegypti.1. batches of aëdes (stegomyia) aegypti which had fed on monkeys in the early febrile stage of yellow fever and which has subsequently passed the usually accepted extrinsic incubation period for the virus, failed to transmit the disease to normal monkeys in approximately fifty per cent of the experiments. during the same time over eighty per cent of blood transfers were successful. 2. the monkeys which failed to show fever following mosquito bites later proved resistant to the inoculation of blo ...192919869665
recent laboratory contributions to the control of yellow fever: (section of tropical diseases and parasitology).the most important recent laboratory contributions to the control of yellow fever will be briefly summarized under three headings: (1) methods of diagnosis, (2) transmission, and (3) protection.(1) methods of diagnosis.-the development of improved methods of identification, in particular by immunity tests, has made it possible to diagnose yellow fever with much greater certainty. moreover, since the immunity following an attack of the disease is usually of life-long duration, it is possible to d ...193319989606
the transmission of equine encephalomyelitis virus by aedes aegypti.in confirming kelser's work on the transmission of equine encephalomyelitis of the western type by aëdes aegypti it has been learned that the mosquitoes must be fed virus of high titer if positive results are to be secured. a period of from 4 to 5 days after feeding either on infected guinea pigs or on brain containing virus must elapse before the disease is transmitted by biting, but after this time transmission regularly results for a period of about 2 months. by inoculation, virus can be demo ...193519870442

the multiplication of the virus of yellow fever in aedes aegypti.aëdes aegypti have been shown to be capable of multiplying the asibi strain of yellow fever virus in their bodies. following the ingestion of infected blood, the content of virus falls for several days, reaching a minimum during the 1st week. it then increases rapidly until quantities of virus greater than those previously encountered can be demonstrated. the actual final amount of virus demonstrable, however, is subject to variations of which we know little.193719870651
the absence from the urine of pernicious anemia patients of a mosquito growth factor present in normal urine.extracts prepared from the urine of normal persons or patients with aplastic anemia or leukemia contain a substance, possibly flavine or a flavine compound, which under suitable conditions of test enhances the growth of larvae of the mosquito, aëdes aegypti. this substance is lacking, or is present in much smaller amount, in extracts from the urine of pernicious anemia patients showing symptoms of the disease. extracts from the urine of the same patients after adequate treatment contain as much ...193819870733
