ABSTRACT In this study, we detected African Swine Fever Virus (ASFV) in Dermacentor (Ixodidae) from sheep and bovines using small RNA sequencing. To validate this result, a 235-bp DNA segment was detected in a number of DNA samples from D. silvarum and sheep blood. This 235-bp segment had an identity of 99% to a 235-bp DNA segment of ASFV and contained three single nucleotide mutations (C38T, C76T and A108C). C38T, resulting in a single amino acid mutation G66D, suggests the existence of a new… 
Full-length genome sequence of segmented RNA virus from ticks was obtained using small RNA sequencing data
TLDR
This is the first study in which 5′ and 3′ sRNAs were used to generate full-length genome sequences of, but not limited to, RNA viruses, and demonstrated the feasibility of using the sRNA-seq based method for the detection of viruses in pooled two and even possible one small ticks.
Putative Role of Arthropod Vectors in African Swine Fever Virus Transmission in Relation to Their Bio-Ecological Properties
TLDR
This review explores the current body of knowledge on the most common arthropod families present in metropolitan France and examines their potential role in spreading ASF—by active biological or mechanical transmission or by passive transport or ingestion—in relation to their bio-ecological properties.
Comparative vector competence of the Afrotropical soft tick Ornithodoros moubata and Palearctic species, O. erraticus and O. verrucosus, for African swine fever virus strains circulating in Eurasia
TLDR
Transmission trials with two Palearctic soft tick species show that O. erraticus and O. verrucosus are unlikely to be capable vectors of ASFV strains currently circulating in Eurasia, and the persistence of infection in soft ticks for several months reaffirms that the infectious status of a given tick species is only part of the data required to assess its vector competence for ASFF.
African swine fever in China: a new twist to an emerging crisis
TLDR
Chen et al. (2019) adds a new twist to this emerging crisis by showing for the first time that ASFV can infect sheep and bovines in addition to Suidae, and Dermacentor hard ticks (not just Ornithodoros soft ticks) can be vectors.
Bioinformatics analysis of the 2019 novel coronavirus genome
TLDR
The analytical results show that 2019-nCoV with large differences from the SARS coronavirus, may originate from BB coronaviruses in bats, and a preliminary study of the mechanisms in the cross-species infection and host adaption of BB coronvirus is conducted.
Prevention and Control Strategies of African Swine Fever and Progress on Pig Farm Repopulation in China
TLDR
The important aspects of three key elements about African swine fever virus (ASFV) transmission are summarized, including the sources of infection, transmission routes, and susceptible animals.
Should zinc be used for COVID-19 prophylaxis or treatment? A rapid review
TLDR
The study authors found that treatment with a combination of zinc, azithromycin and hydroxychloroquine in patients hospitalised with COVID-19 resulted in increased odds of being discharged home and reduced odds of death or being transferred to a hospice.

TLDR
African swine fever is a serious, highly contagious, viral disease of pigs that has caused outbreaks in pigs as far west as the easternmost countries of the E.U., and it has also been detected in wild boar in Iran.
One PCR Method Used for Detection of African Swine Fever Virus
TLDR
A polymerase chain reaction (PCR) developed for detection of African swine fever virus (ASFV) based on the VP72 gene revealed that it had a good specificity, no cross-reaction was observed with other pig pathogens and could be used in diagnosis, prevention and control of African Swine fever.
African Swine Fever Virus: A Review
TLDR
The interplay of the viral products with host pathways, which are relevant for virus replication, provides the basic information needed for the identification of potential targets for the development of intervention strategies against this disease.
Tick-borne pathogens and the vector potential of ticks in China
TLDR
The numbers of tick-associated pathogens and tick-borne diseases in China are probably underestimated because of the complex distribution and great diversity of tick species in this country.
Biological Vectors of African Swine Fever
TLDR
The biological and ecological characteristics of Ornithodoros ticks, virus-tick interaction, ornithodorOS ticks control and their distribution in China are described in order to lay the foundation for effective control of African swine fever.
Using Small RNA Deep Sequencing Data to Detect Human Viruses
TLDR
Results suggest the sRNA-seq can be used to detect viruses in mammals and humans and HIV-1 was found in clinical samples without the HIV-positive reports, and SMRV was find in Diffuse Large B-Cell Lymphoma cells for the first time.
Complemented Palindromic Small RNAs First Discovered from SARS Coronavirus
TLDR
The existence of complemented palindromic small RNAs (cpsRNAs) is reported for the first time and it is suggested that SARS-CoV-cpsR-19 could play a role in SARS -CoV infection or pathogenesis.
Deep Sequencing of Small RNAs in Tomato for Virus and Viroid Identification and Strain Differentiation
TLDR
Data suggest that the sRNA deep sequencing technology will likely become an efficient and powerful generic tool for virus identification in plants and animals.
Two featured series of rRNA-derived RNA fragments (rRFs) constitute a novel class of small RNAs
TLDR
Results indicated the rRF5 and rRF3 series were not random intermediates or products during rRNA degradation, but could constitute a new class of small RNAs that deserves further investigation.
