There is a wide intersection where animal and human lives interact or mimic each other behaviorally or biologically. A lot of the products that are part of our day-to-day were first validated by animals, and eventually found their way to us. From food to beauty products to scientific developments, animals deal with a lot behind the scenes. Some humans are cognizant of what is happening backstage, while others only see the final presentation. Either way, all of us have our opinions in support or against animal treatment. The project is heavily inspired from my experience in a neurorehabilitation lab, so the foundation is similar to the structure and function of neurons. Through this project, I am focusing on one aspect of this debate, which is animal testing in the scietific setting. The goal of the project is not to force the viewer to choose one side, but to understand the big picture and the reasoning of the opposing side.
This study highlights the significance of zoonotic diseases, which make up almost 60% of infectious diseases in humans, and their origin from animals. Among mammalian viruses, primates, bats, and rodents have been identified as high-risk carriers. Within the rodent family Cricetidae, the species complex of Peromyscus eremicus, Peromyscus californicus, Peromyscus fraterculus, and Osgoodomys banderanus have been found to play a crucial role in disease transmission. These four species are phylogenetically related and share similar physical appearances and ecological niches. They have been identified as carriers of several zoonotic diseases, including Hantavirus, Arenavirus, Yersinia pestis, and Flavivirus, with a history of spread to humans. Despite their implications for public health, many of these species remain understudied. Thus, this study aims to provide a systematic review of the existing literature on these four species to summarize the findings on virus prevalence and distribution. The review shows that sampling efforts have been uneven and recent efforts have been lacking, with potential undiscovered zoonotic diseases. The concentration of sampling efforts in California and gaps in the literature are concerning, especially with changing agriculture and climate change potentially affecting rodent communities.
