Abstract We identified hepatitis E virus (HEV) in rabbits Virginia, USA. HEV RNA was detected 14 (16%) of 85 serum samples and 13 (15%) fecal samples. Antibodies against were 31 (36%) Sequence analyses showed that from is closely related to genotype 3.
Hepatitis E virus (HEV) is an important human pathogen. In addition to humans, HEV has also been identified in pig, chicken, mongoose, deer, rat, rabbit and fish. There are four recognized two putative genotypes of mammalian HEV. Genotypes 1 2 restricted while 3 4 zoonotic. The recently a distant member genotype 3. Here, we first expressed purified the recombinant capsid protein showed that cross-reacted with antibodies raised against avian, swine Conversely, proteins derived from Since pigs...

ABSTRACT. Rift Valley fever (RVF) is a zoonotic disease of public health and economic importance. Uganda has reported sporadic outbreaks RVF in both humans animals across the country, especially southwestern part “cattle corridor” through an established viral hemorrhagic surveillance system. We report 52 human cases laboratory-confirmed from 2017 to 2020. The case fatality rate was 42%. Among those infected, 92% were males 90% adults (≥ 18 years). Clinical symptoms characterized by (69%),...
Hepatitis E virus (HEV) is an important human pathogen with pigs and other species serving as natural animal reservoirs. Ample evidence documents sporadic cases of hepatitis acquired via consumption undercooked meat. Chronic in immunosuppressed individuals are mostly caused by zoonotic HEV swine origin. We report here the identification genotype 3 from non-liver commercial pork local grocery stores southwest Virginia, association seropositivity to meat healthy young adults at a university...
Abstract To our knowledge, environmental isolation of Burkholderia pseudomallei, the causative agent melioidosis, from continental United States has not been reported. We report a case melioidosis in Texas resident. Genomic analysis indicated that isolate groups with B. pseudomallei isolates patients same region, suggesting possible endemicity to this region.
In June 2019, the Bolivian Ministry of Health reported a cluster cases hemorrhagic fever that started in municipality Caranavi and expanded to La Paz. The cause these was unknown.We obtained samples for next-generation sequencing virus isolation. Human rodent specimens were tested by means virus-specific real-time quantitative reverse-transcriptase-polymerase-chain-reaction assays, sequencing, isolation.Nine identified; four patients with this illness died. etiologic agent identified as...
Lymphocytic choriomeningitis virus (LCMV) infection in immunocompromised hosts can result disseminated disease, meningoencephalitis, and death. Published cases transplant recipients have been traced to transmission from infected donors. We report 2 of serious, non-donor-derived LCMV solid organ recipients. Initial identification was done by using metagenomic next-generation sequencing (mNGS). Subsequent evaluations confirmatory testing involved molecular diagnostics, serology, phylogenetic...
Hepatitis E virus (HEV) is an important but extremely understudied human pathogen. Genotypes 1 and 2 are restricted to humans, whereas genotypes 3 4 zoonotic, infecting both humans pigs. This report describes, for the first time, successful rescue of infectious HEV in vitro vivo from cloned cDNA a genotype (strain TW6196E). The complete genomic sequence TW6196E was determined full-length clone (pHEV-4TW) assembled. Capped RNA transcripts pHEV-4TW were replication competent Huh7 cells...
Hepatitis E virus (HEV) is a single-strand positive-sense RNA in the family Hepeviridae. The disease caused by HEV, hepatitis E, an important public health problem developing countries of Asia and Africa also endemic many industrialized countries, including United States. HEV has been identified from several other animal species addition to humans, pig, chicken, mongoose, deer, rabbit, ferret, bat, fish. Here we report complete genome sequence first strain rabbits Sequence phylogenetic...
Abstract On April 20, 2018, the Kween District Health Office in District, Uganda reported 7 suspected cases of human anthrax. A team from Ministry and partners investigated identified 49 cases, 3 confirmed 46 suspected; no deaths were reported. Multiple exposures handling carcass a cow that had died suddenly significantly associated with cutaneous anthrax, whereas eating meat was gastrointestinal Eating undercooked but boiling for >60 minutes protective. We recommended providing postexposure...
An animal model that fully recapitulates severe COVID-19 presentation in humans has been a top priority since the discovery of SARS-CoV-2 2019. Although multiple models are available for mild to moderate clinical disease, develop disease still needed. Mink experimentally infected with developed acute respiratory as evident by radiological, and histological changes. Virus was detected nasal, oral, rectal, fur swabs. Deep sequencing from oral swabs lung tissue samples showed repeated...
