Tick-borne encephalitis virus (TBEV) is divided into three subtypes: European (TBEV-Eu), Siberian (TBEV-Sib), and Far Eastern (TBEV-FE) subtypes. The geographical range of TBEV-Eu dominates in Europe, but this subtype is present focally across the whole non-tropical forested Eurasian belt, through Russia to South Korea. However, the TBEV-Eu strains isolated outside Europe remain poorly characterized. In this study, full-genome sequences of eight TBEV-Eu isolates were determined. These strains were isolated from Ixodes persulcatus ticks, long-tailed ground squirrel (Spermophilus undulatus), and human blood in the natural foci of Western and Eastern Siberia, Russia...

There are currently no approved antiviral therapies against medically important human flaviviruses. The imino-C-nucleoside BCX4430 shows broad-spectrum antiviral activity against a wide range of RNA viruses. Here, we demonstrate that BCX4430 inhibits tick-borne species of the genus Flavivirus; however, the antiviral effect varies against individual species. Micro-molar BCX4430 levels inhibited tick-borne encephalitis virus (TBEV); while, approximately 3-8-fold higher concentrations were needed to inhibit louping ill virus and Kyasanur Forest disease virus...

Infectious encephalitis is a severe disease leading to a high mortality and morbidity. The most frequent causes include Herpes simplex virus, Varicella Zoster virus, Listeria monocytogenes, and Mycobacterium tuberculosis. Urgent treatment is required (anti-infective therapy and nonspecific supportive care). The aim of this study was to define treatment strategy, empirical and after microbiological documentation at 48hours, through a systematic literature review.

We present a case of endemic tick-borne encephalitis (TBE) occurring in June 2016 in the eastern part of the Netherlands in an area where a strain of TBE virus, genetically different from the common TBE virus strains in Europe, was reported in ticks in 2016. With the start of the tick season in spring, this second autochthonous Dutch TBE case should remind physicians to consider the possibility of endemic TBE in patients with respective symptoms.

Caprine arthritis encephalitis virus (CAEV) has been reported in different countries worldwide, based on serological and molecular detection. In Argentina, the prevalence of CAEV infections is increasing, with goats showing symptoms associated mostly with cachexia and arthritis. Although in Argentina the virus has been detected by serology, it has never been isolated or characterized. Thus, the objectives of this work were to isolate and analyze the nucleotide sequences of the gag gene of Argentine CAEV strains and compare them with those of other SRLVs previously reported...

BACKGROUND: Inkoo virus (INKV) is a less known mosquito-borne virus belonging to Bunyaviridae, genus Orthobunyavirus, California serogroup. Studies indicate that INKV infection is mainly asymptomatic, but can cause mild encephalitis in humans. In northern Europe, the sero-prevalence against INKV is high, 41% in Sweden and 51% in Finland. Previously, INKV RNA has been detected in adult Aedes (Ae.) communis, Ae. hexodontus and Ae. punctor mosquitoes and Ae. communis larvae, but there are still gaps of knowledge regarding mosquito vectors and genetic diversity...

BACKGROUND: Flaviviruses are a genre of closely related viral pathogens which emerged in the last decades in Brazil and in the world. Saint (St.) Louis encephalitis virus (SLEV) is a neglected flavivirus that can cause a severe neurological disease that may lead to death or sequelae. St. Louis encephalitis pathogenesis is poorly understood, which hinders the development of specific treatment or vaccine. METHODS: To address this problem, we developed a model of SLEV infection in mice to study mechanisms involved in the pathogenesis of severe disease...

Psoriasis is a chronic inflammatory skin disorder associated with immune dysregulation and use of systemic immunosuppressive treatments that may predispose toward serious infections. We sought to determine the rates of serious infections in hospitalized patients with psoriasis. We analyzed data from the 2002-2012 Nationwide Inpatient Sample, containing a 20% sample of all US hospitalizations. Psoriasis was determined by a validated algorithm using ICD-9-CM codes. In multivariate logistic regression models adjusting for socio-demographics, psoriasis was associated with multiple serious infections, including methicillin-resistant Staphylococcus aureus (odds ratio [95% confidence intervals] 1...

Members of the genus Acanthamoeba are of the most common protozoa that has been isolated from a variety of environment and affect immunocompromised individuals, causing granulomatous amoebic encephalitis and skin lesions. Acanthamoeba, in immunocompetent patients, may cause a keratitis related to corneal microtrauma. These free-living amoebas easily adapt to the host environment and wield metabolic pathways such as the energetic and respiratory ones in order to maintain viability for long periods. The energetic metabolism of cysts and trophozoites remains mostly unknown...

The aim of our study was to detect differentially regulated proteins and specific signaling pathways in Mongolian gerbil brains during chronic Toxoplasma gondii (T.gondii) PRU strain infection. We use a iTRAQ-based strategy to detecte 4935 proteins, out of which 110 proteins were differentially expressed (>/=2.0-fold, p value <0.05) when the brain of gerbils infected with T.gondii was compared to control brain tissues. We confirmed the authenticity and the accuracy of iTRAQ results through quantitative real-time PCR and western blot (WB), which was consistent with mass spectrometry analysis...

Epstein-Barr virus (EBV)-associated lymphoproliferative disorders (LPDs) sometimes occur following Anti-thymocyte globulin (ATG) administration for allogenic stem cell transplantation but are rare in aplastic anemia (AA) patients. A 55-year-old woman with AA following ATG developed refractory fever and was diagnosed with EBV-LPD. She was successfully treated with weekly rituximab monotherapy; however, she developed EBV encephalitis. She was admitted to the intensive care unit and finally recovered from unconsciousness...

Free living amoebae of the genus Acanthamoeba are the causal agents of a sight threatening ulceration of the cornea called Acanthamoeba keratitis, and the rare but usually fatal granulomatous amoebic encephalitis. Although there are many therapeutic options for the treatment of Acanthamoeba infections, they are generally lengthy and/or have limited efficacy. For the best clinical outcome, the treatments should target both the trophozoite and the cyst stages as the later are known to confer resistance to treatment...

BACKGROUND: Herpes simplex virus (HSV) is a common human pathogen that causes a variety of diseases, including oral-labial, genital lesions and life-threatening encephalitis. The antiviral nucleoside analogues such as acyclovir are currently used in anti-HSV therapies; however, clinical overuse of these drugs has led to the emergence of drug-resistant viral strains. Hence, there is an urgent need to develop new anti-HSV agents. METHODS: To identify novel anti-HSV-1 compounds, we screened the LOPAC small scale library of 1280 bioactive compounds to identify inhibitors of HSV-1-induced necroptosis...
