The stochastic gravitational-wave background is a superposition of sources that are either too weak or numerous to detect individually. In this study, we present the results from cross-correlation analysis on data Advanced LIGO's second observing run (O2), which combine with first (O1). We do not find evidence for background, so place upper limits normalized energy density in gravitational waves at 95% credible level...
The ecology and distribution of Bacillus anthracis is poorly understood despite continued anthrax outbreaks in wildlife livestock throughout the United States. Little work available to define potential environments that may lead prolonged spore survival subsequent outbreaks. This study used genetic algorithm for rule-set prediction modeling system model ecological niche B. contiguous States using several environmental variables. modeled defined by a narrow range normalized difference...
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast spinning neutron stars with asymmetry around their rotation axis, using data from the second observing run Advanced LIGO detectors. Three different semicoherent methods are used to in a gravitational-wave frequency band 20 1922 Hz and first derivative $\ensuremath{-}1\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}$...
Arboviral disease transmission by Aedes mosquitoes poses a major challenge to public health systems in Ecuador, where constraints on services and resource allocation call for spatially informed management decisions. Employing unique dataset of larval occurrence records provided the Ecuadorian Ministry Health, we used ecological niche models (ENMs) estimate current geographic distribution aegypti using mosquito presence as proxy risk transmission. ENMs built with Genetic Algorithm Rule-Set...
Abstract Emerging infectious diseases are increasingly understood as a hallmark of the Anthropocene 1–3 . Most experts agree that anthropogenic ecosystem change and high-risk contact among people, livestock, wildlife have contributed to recent emergence new zoonotic, vector-borne, environmentally-transmitted pathogens 1,4–6 However, extent which these factors also structure landscapes human infection outbreak risk is not well understood, beyond certain well-studied disease systems 7–9 Here,...
Early studies confirmed Bacillus anthracis in emesis and feces of flies under laboratory conditions, but there is little empirical field evidence supporting the roles anthrax transmission. We collected samples during outbreaks affecting livestock native exotic wildlife on two ranches West Texas (2009-2010). Sampling included animal carcasses, maggots, adult feeding or within several meters leaves from surrounding vegetation. Microbiology PCR were used to detect B. samples. Viable and/or...
Anthrax, caused by the bacterium Bacillus anthracis, is a zoonotic disease that persists throughout much of world in livestock, wildlife, and secondarily infects humans. This true across Central Asia, particularly Steppe region, including Kazakhstan. study employed Genetic Algorithm for Rule-set Prediction (GARP) to model current future geographic distribution anthracis Kazakhstan based on A2 B2 IPCC SRES climate change scenarios using 5-variable data set at 55 km2 8 6-variable BioClim km2....
Background Brucellosis is a zoonotic disease of global importance infecting humans, domestic animals, and wildlife. Little known about the epidemiology persistence brucellosis in wildlife Southern Africa, particularly Botswana. Methods Archived samples from Botswana (1995–2000) were screened with Rose Bengal Test (RBT) fluorescence polarization assay (FPA) included African buffalo (247), bushbuck (1), eland (5), elephant (25), gemsbok giraffe (9), hartebeest (12), impala (171), kudu (27),...
We modeled the ecological niche of a globally successful Bacillus anthracis sublineage in United States, Italy and Kazakhstan to better understand geographic distribution anthrax potential associations between regional populations ecology. Country-specific ecological-niche models were developed reciprocally transferred other countries determine if pathogen presence could be accurately predicted on novel landscapes. Native endemic areas within each country, but failed predict known...
The ecology and distribution of B. anthracis in Australia is not well understood, despite the continued occurrence anthrax outbreaks eastern states country. Efforts to estimate spatial extent risk disease have been limited a qualitative definition an belt extending from southeast Queensland through centre New South Wales into northern Victoria. This does consider role environmental conditions anthracis. Here, we used genetic algorithm for rule-set prediction model system (GARP), historical...
Anthrax is hyper-endemic in West Africa. Despite the effectiveness of livestock vaccines controlling anthrax, underreporting, logistics, and limited resources makes implementing vaccination campaigns difficult. To better understand geographic limits elucidate environmental factors related to its occurrence, identify human populations at risk, we developed predictive models suitability anthrax Ghana. We obtained data on location date from veterinary outbreak response records Ghana during...
Increasing attention has focused on health outcomes of Campylobacter infections among children younger than 5 years in low-resource settings. Recent evidence suggests that colonization by species contributes to environmental enteric dysfunction, malnutrition, and growth faltering young children. are zoonotic, factors from humans, animals, the environment involved transmission. Few studies have assessed geospatial effects along with human animal infections. Here, we leveraged Genomics...
Brucella suis infection in the United States is typically from feral swine exposure. We describe a case of B. cardiac implantable device man exposed to meat and blood Florida, USA. The was diagnosed using culture, molecular diagnostics, whole-genome sequencing.
To map the distribution of anthrax outbreaks and strain subtypes in Kazakhstan during 1937-2005, we combined geographic information system technology genetic analysis by using archived cultures data. Biochemical tests confirmed identity 93 National Culture Collection as Bacillus anthracis. Multilocus variable number tandem repeat genotyping identified 12 genotypes. Cluster comparing these genotypes with previously published indicated that most (n = 78) isolates belonged to described A1.a...
This case study confirms the interaction between necrophilic flies and white-tailed deer, Odocoileus virginianus, during an anthrax outbreak in West Texas (summer 2005). Bacillus anthracis was identified by culture PCR from one of eight pooled fly collections deer carcasses on a ranch with well-documented history anthrax. These results provide first known isolation B. flesh-eating associated wildlife North America are discussed context ecology epizootics.
Diarrheal illness remains a leading cause of global morbidity and mortality, with the majority deaths occurring in children <5 years age. Lack resources often prohibits evaluation outbreak characteristics limits progress managing this important disease syndrome, particularly Africa. Relying only on existing medical staff hospital resources, we assess use questionnaire survey tool to identify baseline during recurrent diarrheal outbreaks Chobe, Botswana. Using historical surveillance data...
