One year after the first autochthonous transmission of West Nile virus (WNV) to birds and horses in Germany, an epizootic emergence WNV was again observed 2019. The number infected considerably higher compared 2018 (12 birds, two horses), resulting observation epidemy Germany: 76 cases 36 five confirmed mosquito-borne, human cases. We demonstrated that Germany experienced several introduction events strains a distinct group (Eastern German clade), which introduced as single event, dominated...
The emergence of West Nile virus (WNV) and Usutu (USUV) in Europe resulted significant outbreaks leading to avifauna mortality human infections. Both viruses have overlapping geographical, host vector ranges, are often co-circulating Europe. In Germany, a nationwide bird surveillance network was established monitor these zoonotic arthropod-borne migratory resident birds. this framework, co-infections with WNV USUV were detected six dead birds collected 2018 2019. Genomic sequencing...
Phytol (3,7,11,15-tetramethylhexadec-2-en-1-ol; PHY), the alcoholic diterpenoid is particularly interesting due to its diverse activities found in literature. This study evaluated vitro and vivo antioxidant capacity of PHY.We conducted DPPH• (2,2-diphenyl-1-picrylhydrazyl) ABTS•+ (2,2'-azino-bis(3- ethylbenzthiazoline-6-sulphonic acid)) radical scavenging tests as vitro, while Saccharomyces cerevisiae test vivo. For tests, trolox for hydrogen peroxide (H2O2) were taken standard...
This study aimed to detect Salmonella from retail meat collected nine wet markets in Metro Manila, and identify the subtypes of isolates using molecular serotyping assays previously developed primers. Of 720 samples, 57.64% were found be Salmonella-contaminated. The most predominant serogroup was O:3, serogroups O:4, O:6,7, O:8, O:9, undetermined also found. Most frequently detected bovine S. 3:e,h:1,6 (putative identity: Anatum) S: 4:e,h:1,2 Saintpaul), porcine Anatum), 8:i:z6 Kentucky)...
Abstract Background Multiple reports have described neonatal SARS‐CoV‐2 infection, including likely in utero transmission and early postnatal but published estimates of infection range by geography design type. Objectives To describe maternal, pregnancy characteristics among neonates born to people with during testing results. Methods Using aggregated data from the Surveillance for Emerging Threats Mothers Babies Network (SET‐NET) describing infections 20 January 2020 31 December 2020, we...
Mammalian orthobornaviruses, such as Borna disease virus 1 (BoDV-1) and variegated squirrel bornavirus 1, are zoonotic pathogens that cause fatal encephalitis in humans. BoDV-2, another mammalian orthobornavirus with high genetic homology to BoDV-1, is believed share the same geographical distribution indicating its potential risk human health. However, due limited number of isolations, virological characteristics pathogenicity infectivity, remain largely unexplored. Here, we re-evaluated...
West Nile virus (WNV) is the most widespread arthropod-borne (arbo) and primary cause of arboviral encephalitis globally. Members WNV species genetically diverged are classified into different hierarchical groups below rank. However, demarcation criteria for allocating sequences these remain individual inconsistent, use names levels unstructured. In order to have an objective comprehensible grouping sequences, we developed advanced workflow using 'affinity propagation clustering' algorithm...
Utilizing molecular methods for monitoring and determining water quality in developing countries can be problematic. Effective extraction storage of DNA from environmental samples is especially difficult due to lack access sufficient laboratory facilities work. Use a commercial product the DNA, as well its application microbial surface waters, was evaluated compared. Surface collected Chao Phraya River Thailand were processed enumerate Escherichia coli. Quantification done through culture...
Abstract Proactive approaches in preventing future epidemics include pathogen discovery prior to their emergence human and/or animal populations. Playing an important role discovery, high-throughput sequencing (HTS) enables the characterization of microbial and viral genetic diversity within a given sample. In particular, metagenomic HTS allows unbiased taxonomic profiling sequences; hence, it can identify novel highly divergent pathogens such as viruses. Newly discovered sequences must be...

Abstract Viruses belonging to the genus Orthobornavirus within family Bornaviridae are known infect various vertebrate species, including mammals and birds. Within genus, species bornaense includes two mammalian viruses: Borna disease virus 1 (BoDV-1), prototype of family, its closely related virus, BoDV-2. BoDV-1 was identified as causative agent (BD) in horses, sheep, humans, other mammals. BoDV-2 first detected a pony eastern Austria 1999 that exhibited severe incurable neurological...
<title>Abstract</title> Borna disease virus 1 (BoDV-1) is the causative agent of disease, a progressive and mostly fatal neurologic disorder domestic mammals humans, resulting from spill-over infection its natural reservoir host, bicolored white-toothed shrew (Crocidura leucodon). The known BoDV-1 endemic area remarkably restricted to parts Germany, Austria, Switzerland Principality Liechtenstein. To gain comprehensive data on occurrence BoDV-1, we analysed diagnostic material suspected...
Abstract Aplectana hylambatis (Baylis, 1927) is a widespread nematode in South America that infects different species of anurans from families. Although the morphology this shows intraspecific variations and well studied, A. does not have genetic characterisation. Therefore, present study aimed to provide first characterisation parasite, based on 18S 28S rDNA sequences, as evaluate its phylogenetic position family Cosmocercidae. The specimens showed no major morphological were assigned...
