Summary
Peste des petits ruminants (PPR) has reappeared in UAE wild ruminants. This virus strain, belonging to lineage IV, highlights the potential role of wild animals in spreading PPR to domestic livestock.
Area of Science:
- Veterinary Virology
- Wildlife Epidemiology
- Infectious Disease Dynamics
Background:
- Peste des petits ruminants (PPR) is a highly contagious viral disease affecting small ruminants.
- Previous PPR outbreaks have been documented in the Arabian Peninsula.
- The role of wild ruminant populations in PPR epidemiology requires further investigation.
Purpose of the Study:
- To report the recurrence of peste des petits ruminants (PPR) in wild ruminants in the United Arab Emirates.
- To characterize the PPR virus strain involved in the recent outbreak.
- To assess the potential epidemiological significance of wild ruminants in PPR transmission.
Main Methods:
- Morphological, immunohistochemical, serological, and molecular diagnostic techniques were employed for PPR confirmation.
- Phylogenetic analysis was conducted on the isolated PPR virus strain.
- Epidemiological data was collected from affected wild ruminant populations.
Main Results:
- PPR recurrence was confirmed in several wild ruminant species in the UAE.
- The identified PPR virus strain belongs to lineage IV.
- This lineage differs from previously isolated PPR strains in the Arabian Peninsula.
- Wild ruminants were found to harbor the PPR virus.
Conclusions:
- Wild ruminants in the UAE are susceptible to PPR and can harbor the virus.
- The presence of a distinct PPR virus lineage (IV) in wild ruminants has significant epidemiological implications.
- Wild ruminant populations may serve as a crucial reservoir and source for PPR outbreaks in domestic small ruminants, necessitating enhanced surveillance and control strategies.

01:28Rabies
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...
00:53Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
02:40Epiphytes, Parasites, and Carnivores
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the biosynthesis of the...
00:55Parental Care
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
02:04Conservation of Small Populations
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...
