Phylogenetic and Geographical Relationships of Hantavirus Strains in Eastern and Western Paraguay
Am. J. Trop. Med. Hyg., 75(6), 2006, pp. 1127–1134 Copyright © 2006 by The American Society of Tropical Medicine and Hygiene PHYLOGENETIC AND GEOGRAPHICAL RELATIONSHIPS OF HANTAVIRUS STRAINS IN EASTERN AND WESTERN PARAGUAY YONG KYU CHU, BROOK MILLIGAN, ROBERT D. OWEN, DOUGLAS G. GOODIN, AND COLLEEN B. JONSSON* Emerging Infectious Disease Program, Department of Biochemistry and Molecular Biology, Southern Research Institute, Birmingham, Alabama; Department of Biology, New Mexico State University, Las Cruces, New Mexico; Department of Biological Sciences, Texas Tech University, Lubbock, Texas; Department of Geography, Kansas State University, Manhattan, Kansas Abstract. Recently, we reported the discovery of several potential rodent reservoirs of hantaviruses in western (Holochilus chacarius) and eastern Paraguay (Akodon montensis, Oligoryzomys chacoensis, and O. nigripes). Compari- sons of the hantavirus S- and M-segments amplified from these four rodents revealed significant differences from each another and from other South American hantaviruses. The ALP strain from the semiarid Chaco ecoregion clustered with Leguna Negra and Rio Mamore (LN/RM), whereas the BMJ-ÑEB strain from the more humid lower Chaco ecoregion formed a clade with Oran and Bermejo. The other two strains, AAI and IP37/38, were distinct from known hantaviruses. With respect to the S-segment sequence, AAI from eastern Paraguay formed a clade with ALP/LN/RM, but its M-segment clustered with Pergamino and Maciel, suggesting a possible reassortment. AAI was found in areas -
Hantavirus Disease Were HPS Is More Common in Late Spring and Early Summer in Seropositive in One Study in the U.K
Hantavirus Importance Hantaviruses are a large group of viruses that circulate asymptomatically in Disease rodents, insectivores and bats, but sometimes cause illnesses in humans. Some of these agents can occur in laboratory rodents or pet rats. Clinical cases in humans vary in Hantavirus Fever, severity: some hantaviruses tend to cause mild disease, typically with complete recovery; others frequently cause serious illnesses with case fatality rates of 30% or Hemorrhagic Fever with Renal higher. Hantavirus infections in people are fairly common in parts of Asia, Europe and Syndrome (HFRS), Nephropathia South America, but they seem to be less frequent in North America. Hantaviruses may Epidemica (NE), Hantavirus occasionally infect animals other than their usual hosts; however, there is currently no Pulmonary Syndrome (HPS), evidence that they cause any illnesses in these animals, with the possible exception of Hantavirus Cardiopulmonary nonhuman primates. Syndrome, Hemorrhagic Nephrosonephritis, Epidemic Etiology Hemorrhagic Fever, Korean Hantaviruses are members of the genus Orthohantavirus in the family Hantaviridae Hemorrhagic Fever and order Bunyavirales. As of 2017, 41 species of hantaviruses had officially accepted names, but there is ongoing debate about which viruses should be considered discrete species, and additional viruses have been discovered but not yet classified. Different Last Updated: September 2018 viruses tend to be associated with the two major clinical syndromes in humans, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary (or cardiopulmonary) syndrome (HPS). However, this distinction is not absolute: viruses that are usually associated with HFRS have been infrequently linked to HPS and vice versa. A mild form of HFRS in Europe is commonly called nephropathia epidemica. -

Lund, Sweden. ISSN 0018-0661. Received February 4, 1997. Accepted August 7, 1997 Comparative cytogenetics studies based on conventional staining, CBG, GTG, RBG-banding, Ag-NOR staining, fluorescence in situ hybridization (FISH) using telomere probes, length measurements, and meiotic data were performed on two related but previously undescribed cricetid species referred to as Oligoryzomys sp. 1 and Oligoryzomys sp. 2, respectively, from Pic0 das Almas (Bahia: Brazil) and Serra do Cipo (Minas Gerais: Brazil). Oligoryzomys sp. 1 had 2n = 46 and Oligoryzomys sp. 2 had 2n = 44,44/45.Our banding data and measurements as well as FISH results support the hypothesis that the difference between the diploid numbers occurred by centric fusion events. The karyotypes had conspicuous and distinguishable macro- and micro-chromosomes, and we suppose that the largest pairs (I, 2, and 3) have evolved from a higher diploid number because of successive tandem fusion mechanisms.

Hantavirus Infection: a Global Zoonotic Challenge
VIROLOGICA SINICA DOI: 10.1007/s12250-016-3899-x REVIEW Hantavirus infection: a global zoonotic challenge Hong Jiang1#, Xuyang Zheng1#, Limei Wang2, Hong Du1, Pingzhong Wang1*, Xuefan Bai1* 1. Center for Infectious Diseases, Tangdu Hospital, Fourth Military Medical University, Xi’an 710032, China 2. Department of Microbiology, School of Basic Medicine, Fourth Military Medical University, Xi’an 710032, China Hantaviruses are comprised of tri-segmented negative sense single-stranded RNA, and are members of the Bunyaviridae family. Hantaviruses are distributed worldwide and are important zoonotic pathogens that can have severe adverse effects in humans. They are naturally maintained in specific reservoir hosts without inducing symptomatic infection. In humans, however, hantaviruses often cause two acute febrile diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS). In this paper, we review the epidemiology and epizootiology of hantavirus infections worldwide. KEYWORDS hantavirus; Bunyaviridae, zoonosis; hemorrhagic fever with renal syndrome; hantavirus cardiopulmonary syndrome INTRODUCTION syndrome (HFRS) and HCPS (Wang et al., 2012). Ac- cording to the latest data, it is estimated that more than Hantaviruses are members of the Bunyaviridae family 20,000 cases of hantavirus disease occur every year that are distributed worldwide. Hantaviruses are main- globally, with the majority occurring in Asia. Neverthe- tained in the environment via persistent infection in their less, the number of cases in the Americas and Europe is hosts. Humans can become infected with hantaviruses steadily increasing. In addition to the pathogenic hanta- through the inhalation of aerosols contaminated with the viruses, several other members of the genus have not virus concealed in the excreta, saliva, and urine of infec- been associated with human illness. -

MILLS , Centers for Disease Control and Prevention , National Centers for Infectious Diseases, Special Pathogens Branch , Atlanta , GA 30333 , USA Abstract: Few, if any, human settlements are free of peridomestic rodent populations. The threat of rodent borne zoonotic diseases has been widely recognized since the bubonic plague outbreaks of the Middle Ages . In the last decades, outbreaks of human disease caused by the rodent borne hemorrhagic fever viruses , the arenaviruses (family Arenaviridae), and the hantaviruses (family Bunyaviridae, genus Hantaviru s) have again generated interest in the general public and scientific community regarding the biology of these types of diseases. Recent studie s have identified more than 30 new members of these two groups of viruses. Most are associated with rodents in the family Muridae and many are known to be pathogenic. Ongoing studies are investigating aspects of the ecology and systematics of these viruses and their reservoirs . Ecological studies are currently examining modes of transmission between members of the host species , and environmental factors associated with increased frequency of infection. Systematic research is identifying patterns of co-evolution between the viruses and their hosts. The overall goal of these research efforts is develop predictive models that will identify times and places of increased risk and. therefore provide an opportunity for risk reduction in these areas. -

Forbes 1 1 Department of Biological Sciences, University of Arkansas, Fayetteville, AR 72701, USA; [email protected] (R.J.); [email protected] (K.M.F.) 2 Department of Virology, University of Helsinki, 00290 Helsinki, Finland; Tarja.Sironen@helsinki.fi 3 Department of Veterinary Biosciences, University of Helsinki, 00790 Helsinki, Finland * Correspondence: [email protected] Received: 9 April 2020; Accepted: 24 April 2020; Published: 26 April 2020 Abstract: The number of documented American orthohantaviruses has increased significantly over recent decades, but most fundamental research has remained focused on just two of them: Andes virus (ANDV) and Sin Nombre virus (SNV). The majority of American orthohantaviruses are known to cause disease in humans, and most of these pathogenic strains were not described prior to human cases, indicating the importance of understanding all members of the virus clade. In this review, we summarize information on the ecology of under-studied rodent-borne American orthohantaviruses to form general conclusions and highlight important gaps in knowledge. Information regarding the presence and genetic diversity of many orthohantaviruses throughout the distributional range of their hosts is minimal and would significantly benefit from virus isolations to indicate a reservoir role. Additionally, few studies have investigated the mechanisms underlying transmission routes and factors affecting the environmental persistence of orthohantaviruses, limiting our understanding of factors driving prevalence fluctuations. As landscapes continue to change, host ranges and human exposure to orthohantaviruses likely will as well. Research on the ecology of neglected orthohantaviruses is necessary for understanding both current and future threats to human health. -
A Global-Scale Evaluation of Mammalian Exposure and Vulnerability to Anthropogenic Climate Change
A Global-Scale Evaluation of Mammalian Exposure and Vulnerability to Anthropogenic Climate Change Tanya L. Graham A Thesis in The Department of Geography, Planning and Environment Presented in Partial Fulfillment of the Requirements for the Degree of Master of Science (Geography, Urban and Environmental Studies) at Concordia University Montreal, Quebec, Canada March 2018 © Tanya L. Graham, 2018 Abstract A Global-Scale Evaluation of Mammalian Exposure and Vulnerability to Anthropogenic Climate Change Tanya L. Graham There is considerable evidence demonstrating that anthropogenic climate change is impacting species living in the wild. The vulnerability of a given species to such change may be understood as a combination of the magnitude of climate change to which the species is exposed, the sensitivity of the species to changes in climate, and the capacity of the species to adapt to climatic change. I used species distributions and estimates of expected changes in local temperatures per teratonne of carbon emissions to assess the exposure of terrestrial mammal species to human-induced climate change. I evaluated species vulnerability to climate change by combining expected local temperature changes with species conservation status, using the latter as a proxy for species sensitivity and adaptive capacity to climate change. I also performed a global-scale analysis to identify hotspots of mammalian vulnerability to climate change using expected temperature changes, species richness and average species threat level for each km2 across the globe. The average expected change in local annual average temperature for terrestrial mammal species is 1.85 oC/TtC. Highest temperature changes are expected for species living in high northern latitudes, while smaller changes are expected for species living in tropical locations. -

Small mammals were collected in forest, successional thorn scrub, pasture, and crop fields representing both relatively undisturbed habitats and agroecosystems. A total of 1089 small mammals representing 13 species were captured during 23 296 trap nights. Pastures had the highest species richness as well as the highest number of cap- tures. Some small mammal species such as Calomys laucha and Akodon toba were cap- tured in a variety of habitats whereas others like Holochilus chacarius and Bolomys lasiurus were captured almost exclusively in pastures. -
