Insights

Border disease virus caused the deaths of approximately 3,000 Pyrenean chamois in Spain between 2005-2007. This viral infection was identified as the primary cause, mirroring a 2001 outbreak.

Area of Science:

  • Veterinary Medicine
  • Wildlife Disease Ecology
  • Molecular Virology

Background:

  • The Pyrenean chamois (Rupicapra pyrenaica pyrenaica) population in northeastern Spain experienced significant mortality events.
  • Previous epizootics, including one in 2001, suggested a viral etiology for chamois deaths.

Purpose of the Study:

  • To identify the causative agent responsible for the deaths of approximately 3,000 Pyrenean chamois between 2005 and 2007.
  • To confirm the role of Border disease virus in the observed mortality.

Main Methods:

  • Samples from deceased Pyrenean chamois were analyzed using reverse transcription-polymerase chain reaction (RT-PCR).
  • Sequencing analysis was performed on viral genetic material to confirm pathogen identification.

Main Results:

  • Border disease virus (BDV) infection was definitively identified in the Pyrenean chamois.
  • RT-PCR and sequencing confirmed BDV as the primary pathogen responsible for the epizootic.

Conclusions:

  • Border disease virus is implicated as the principal cause of the 2005-2007 Pyrenean chamois mortality event.
  • The findings are consistent with the role of BDV in a similar epizootic observed in 2001, highlighting ongoing disease risks.

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Rabies01:28

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...
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
Smallpox01:24

Smallpox

Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.
