Zoonosis is defined as "an infectious disease transmissible under natural conditions between vertebrate animals and human beings". There are more than 150 diseases recognized under the umbrella of zoonosis. Some of the better known examples include: anthrax, bursilosis, hunta virus, bubonic plage, hemoragic fevers like ebola, rabies, and even AIDS.
What is a Zoonosis?
Zoonosis is a disease that can be transmitted to humans from animals.
Researchers in Italy identified a case of reverse zoonosis wherein animals contract the virus from humans. The team detected SARS-CoV-2 in a healthy poodle living with four family members who had COVID-19.
Now, researchers at the U.S. Centers for Disease Control and Prevention (CDC) identified a case of human to animal transmission when SARS-CoV-2 was detected in a healthy poodle dog living with four family members who had COVID-19.
The EU-funded BIO-CRIME project - with support from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) - conducted a scientific investigation on the topic of illegal small animal trade and the associated risk of pathogen transmission.
A fascinating new study discusses the 40 mutations that are seen on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein and their potential effects on viral biology.
A new study in Acta Mathematica Scientia suggests that the virus may have originated in multiple countries almost simultaneously, rather than spreading from China to the rest of the world.
A team of researchers from Saudi Arabia and Spain recently quantified the rapid evolution of SARS-CoV-2 by tracking the mutations of the virus globally, focusing on the receptor-binding domain (RBD) of the virus’s spike protein, which determines its infectivity.
Researchers at the Division of Infection and Immunity, University College London, UK, have provided key insights into the characteristics of the B.1.1.7 (or UK) variant of SARS-CoV-2.
Understanding animal disease is essential if we want to prevent future pandemics, writes Keith Hamilton.
White-tailed deer have been observed to be susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They can also transmit the virus both through direct and indirect contact to one another, researchers find. The research paper is available to be read online in the Journal of Virology.
The study, published on the preprint server bioRxiv*, highlights the need to study viral evolution and pathogenesis in human and animal hosts. This could help prevent future outbreaks that may mimic the magnitude of the current COVID-19 pandemic.
Researchers from the University of Georgia, USA, have found some members of the superfamily Musteloidea – the group that includes badgers and weasels – appear to not only have no effects of the virus, but do little in spreading it.
In a recent report made available on bioRxiv* preprint server, researchers from Poland and Finland reveal a spillover event of mink-adapted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from farmed mink to humans after an extensive adaptation process.
A novel computer algorithm that could create a broadly reactive influenza vaccine for swine flu also offers a path toward a pan-influenza vaccine and possibly a pan-coronavirus vaccine as well, according to a new paper published in Nature Communications.
Researchers at the U.S. Centers for Disease Control and Prevention (CDC) report outbreaks of coronavirus disease (COVID-19) on mink farms in Utah, United States. They surveyed around farms for evidence of exposure and found high SARS-CoV-2 titers, suggesting a possible viral transmission pathway to native wildlife.
A new study has reported evidence that SARS-CoV-2-related coronaviruses (SC2r-CoVs) are circulating in bats in Southeast Asia. This has extended the geographical area where SC2r-CoVs are found, underscoring the urgency of identifying the immediate ancestor of SARS-CoV-2.
Researchers from the UK and China performed a comprehensive analysis of horseshoe bat and pangolin Sarbecoviruses to shed light on the origins of SARS-CoV-2.
Researchers from the US and Australia show that several common peridomestic species (including deer mice, striped skunks and bushy-tailed woodrats) are amenable to infection with SARS-CoV-2.
A team of researchers in China – at Guangzhou University of Chinese Medicine and Yunnan University of Chinese Medicine – recently explored the therapeutic properties of Yinqiao powder in treating COVID-19 symptoms. Their findings were recently published in Phytotherapy Research.
A team of scientists recently demonstrated that white-tailed deer are highly susceptible to SARS-CoV-2 infection. Moreover, the infected animals are capable of transmitting the virus to their non-infected counterparts via indirect contact.
Researchers from the University of Cambridge and the Pirbright Institute in the UK have identified key genetic changes in SARS-CoV-2 that may be responsible for the virus’s jump from bats to humans. The team also determined which animals contain cellular receptors that allow the virus to enter cells more effectively, zoning in on potential animals that acted as an intermediary host in facilitating SARS-CoV-2’s zoonosis.
