Summary
Canine influenza virus (CIV) emerged in racing greyhounds in 2004, originating from an equine virus. This review focuses on CIV, noting its dog-to-dog transmission and undetermined impact on canine health.
Area of Science:
- Veterinary Virology
- Canine Infectious Diseases
Background:
- The 2004 isolation of an influenza virus from racing greyhounds marked a significant event in canine virology.
- This canine influenza virus (CIV) did not originate from known human influenza strains but had an equine lineage.
Purpose of the Study:
- This review focuses on canine influenza virus (CIV).
- It examines the emergence and characteristics of CIV in dogs.
Main Methods:
- Review of scientific literature on canine influenza.
- Analysis of epidemiological data and viral lineage.
Main Results:
- The canine influenza virus (CIV) was identified in racing greyhounds in 2004.
- Evidence confirmed its equine origin and, crucially, its capacity for dog-to-dog transmission.
- This marked the emergence of a novel canine influenza pathogen.
Conclusions:
- Canine influenza virus (CIV) represents a significant development in canine respiratory diseases.
- Further research is needed to fully determine the long-term impact of CIV on canine health due to its recent emergence.

Influenza
Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...
Viral Recombination
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Leaky Scanning
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...
