A wide distribution of Beiji nairoviruses and related viruses in Ixodes ticks in Japan

Ticks and Tick-Borne Diseases
Beiji nairovirus (BJNV), in the family Nairoviridae, the order Bunyavirales, was recently reported as a causative agent of an emerging tick-borne zoonotic infection in China. This study investigated the prevalence of BJNV in ticks in Japan.

Generic amplification and next generation sequencing reveal Crimean-Congo hemorrhagic fever virus AP92-like strain and distinct tick phleboviruses in Anatolia, Turkey

Parasites & Vectors, 2017
Background Ticks are involved with the transmission of several viruses with significant health impact. As incidences of tick-borne viral infections are rising, several novel and divergent tick- associated viruses have recently been documented to exist ...

Lymphopenia: An early indicator of Crimean‐Congo haemorrhagic fever

Tropical Medicine &International Health, Volume 30, Issue 8, Page 831-837, August 2025.
Abstract Objectives Crimean‐Congo haemorrhagic fever is a lethal tick‐borne disease characterised by initially nonspecific symptoms. While thrombocytopenia and leucopenia are established diagnostic markers, there is a need for earlier indicators. This study evaluates lymphopenia as a marker for Crimean‐Congo haemorrhagic fever.

Studies on the pathogenicity of a nairovirus, Dugbe virus, in normal and immunosuppressed mice

Journal of General Virology, 1990
Susceptibility to lethal infection with the KT281/75 strain of the tick-borne nairovirus, Dugbe virus, was similar in an outbred strain and several inbred strains of mice. For the outbred strain, both neural and extraneural routes of virus inoculation resulted in lethal infection, but susceptibility decreased with age and only intracerebral inoculation

Genetic diversity and expanded epidemic area of novel tick-borne pathogen wetland virus in ticks, wild and domestic animals, and patient in China

Emerging Microbes and Infections
Wetland virus (WELV) is a recently identified segmented orthonairovirus associated with human febrile illness in northeastern China. To elucidate its ecological drivers and transmission patterns, we conducted multi-host surveillance in seven eco-climate ...

Tick Species Infesting Livestock in Three Bioclimatic Areas of Senegal: Bioecology, Prevalence of Tick Infestation, Associated Categorical Factors and Crimean‐Congo Haemorrhagic Fever Virus Infection

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.
Ticks were collected between October 2020 and November 2022, from cattle, goats and sheep in the Sahelian, Sudano‐Sahelian and Sudanian zones, and tested for CCHFV infection. A total of 3632 animals were examined and 35.3% (95% CI: 33.8–36.9) found tick‐infested.

Large RNA segment of Dugbe nairovirus encodes the putative RNA polymerase

Journal of General Virology, 1996
The nucleotide sequence of the large (L) RNA segment of Dugbe (DUG) virus (Nairovirus, Bunyaviridae) was determined, completing the first entire genome sequence of a nairovirus. The L segment comprised 12255 nucleotides, making a total genome size of 18855 nucleotides, and the ends showed identity with the ends of the medium (M) and small (S) genomic ...

Control strategies for emerging infectious diseases: Crimean‐Congo hemorrhagic fever management

Health Science Reports, Volume 7, Issue 9, September 2024.
Abstract Background and Aims Crimean‐Congo Hemorrhagic Fever (CCHF) is a significant public health concern transmitted by ticks. This study seeks to thoroughly grasp the epidemiology and transmission patterns of CCHF, which is caused by the CCHF virus (CCHFV), a member of the Nairovirus genus in the Bunyaviridae family.
