Summary
Pigs and wild boar may act as reservoirs for peste des petits ruminants virus (PPRV) lineage IV, a significant threat to livestock in Asia and Africa. This finding is crucial for achieving the 2030 PPRV eradication goal.
Area of Science:
- Veterinary Virology
- Disease Ecology
Background:
- Peste des petits ruminants virus (PPRV) poses a significant threat to global livestock, with eradication targeted for 2030.
- PPRV lineage IV is prevalent across Asia and Africa, necessitating a thorough understanding of its transmission dynamics.
Purpose of the Study:
- To investigate the potential role of suids (pigs and wild boar) and small ruminants as reservoirs for PPRV lineage IV.
- To inform strategies for PPRV eradication by identifying key animal hosts.
Main Methods:
- Transmission trials were conducted using PPRV lineage IV strain Kurdistan/2011.
- The study involved pigs, wild boar, and small ruminants to assess their susceptibility and role in PPRV spread.
Main Results:
- Pigs and wild boar demonstrated a potential role as reservoirs for PPRV.
- Evidence suggests suids can be a source of PPRV infection, impacting transmission cycles.
Conclusions:
- Suids, including pigs and wild boar, are implicated as potential reservoirs for PPRV lineage IV.
- Understanding the role of these species is vital for effective control and eradication programs against PPRV.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

00:43Lysogenic Cycle of Bacteriophages
67.9K
In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

01:10Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

01:30Lytic Cycle of Bacteriophages
78.0K
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...
