Summary
Schmallenberg virus, an orthobunyavirus, caused widespread infections in Azerbaijan
Area of Science:
- Veterinary Virology
- Epidemiology
- Ruminant Health
Background:
- Schmallenberg virus (SBV) is an emerging orthobunyavirus affecting ruminants.
- SBV infection can lead to significant economic losses in livestock due to fever, diarrhea, reduced milk yield, and congenital malformations.
Purpose of the Study:
- To investigate the epidemiological situation of Schmallenberg virus in Azerbaijan following initial suspected cases.
- To monitor the spread and prevalence of SBV in the country's ruminant population.
Main Methods:
- A comprehensive surveillance study was conducted from October 2012 onwards.
- Serum samples and fetal tissues were collected and analyzed using Enzyme-Linked Immunosorbent Assay (ELISA) and quantitative Polymerase Chain Reaction (qPCR).
Main Results:
- The first wave of SBV infections occurred in 2012/2013, primarily in southern Azerbaijan.
- A larger second wave in 2013/2014 resulted in widespread national detection.
- No major outbreaks have been reported since the 2013/2014 season.
Conclusions:
- Schmallenberg virus established itself in Azerbaijan with two significant waves of infection.
- The surveillance data highlights the dynamic spread of SBV in ruminant populations.
- Ongoing monitoring is crucial for managing future SBV outbreaks in the region.

01:28Introduction to Virus
1.4K
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

01:29Viruses with RNA Genomes
883
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
