According to LitCovid, an open-resource literature hub developed with the support of the US National Institute of Health, over 14,000 relevant articles have been posted to PubMed on the 2019 novel coronavirus. Thousands more articles are available as pre-prints. Obviously this explosion of information can be intimidating for the busy veterinarian, but you can use the national and international resources (listed in Table) to stay current on the latest information. Then turn to this review article and our supplemental LafeberVet Literature Search as well as LafeberVet’s Coronavirus in Animals and Determinants of Viral Infectionto dive a bit deeper into our evolving knowledge of SARS-CoV-2.

Coronaviruses are a large group of viruses named for the crown-like spike proteins on their surface. Coronaviruses cause disease in humans and animals, often circulating among camels, cats, and bats. Ferrets are susceptible to infection by the SARS coronavirus (SARS-COv-1), but pathogenicity and host susceptibility can differ based on the viral infective dose and laboratory SARS coronavirus strain. Studies are ongoing to investigate the respiratory pathology and transmission of COVID-19 (SARS-CoV-2) in experimental ferrets.
What determines the viral host range?
One of the critical determinants of viral host range is the interaction between the coronavirus spike (S) protein (Fig 1) and the host cell receptor. Angiotensin-converting enzyme 2 (ACE2), a receptor for the attachment and uptake of the coronavirus that caused Severe Acute Respiratory Syndrome (SARS-CoV-1), is widely expressed […]
Ferrets are susceptible to several strains of human influenza virus, which is spread through the air from coughing, sneezing, and other respiratory secretions. The virus is not only spread from human to ferret, but ferret to ferret and from ferret to human as well. Share this handout with owners to educate them on measures to keep their furry family member healthy as well as the appearance of influenza virus in the ferret.
Shared by a Diplomate of the American College of Veterinary Internal Medicine and the American College of Veterinary Emergency and Critical Care, this veterinary hospital animal bite or scratch checklist provides guidance for the individual as well as the supervisor or clinician in charge. There are also recommendations for care of the animal inflicting the bite or scratch.
Psittacosis or ornithosis is caused by Chlamydophila psittaci, an obligate intracellular bacterial infection of birds. Chlamydophila psittaci may be excreted in feces and oculonasal discharge. Chlamydophila is environmentally labile but remains infectious for months in organic debris. Latently infected birds appear healthy but shed the organism intermittently for months to years. Stressors such as breeding, shipping, crowding, or climatic extremes may activate shedding.
Individuals that work or live with birds may be at risk for zoonotic diseases. An average 250 human cases of Chlamydophila psittaci are reported annually in the United States.
Diarrhea is the most common problem in pet hamsters. In a recent survey of two large American commercial breeding facilities, approximately 3% of shipped hamsters develop diarrhea. Diarrhea caused by enterocolitis can occur in hamsters of any age or breed and is commonly known as “wet-tail”. Clinical signs in weanlings usually include diarrhea, anorexia, ruffled hair, dehydration, weight loss, and death. The mortality rate is often highest in…
An average 250 human cases of Chlamydophila psittaci are reported annually in the United States. Clinical signs typically follows a 5 to 14 day incubation period. Disease ranges from subclinical to systemic illness with severe pneumonia. Most people demonstrate sudden onset fever, headache, malaise, and myalgia with a non-productive cough that can be accompanied by breathing difficulty and chest tightness. Splenomegaly and…
Encephalitozoon cuniculi is an obligatory intracellular microsporidian parasite that can infect a wide range of mammals, including humans. The primary host for E. cuniculi is the rabbit. Infections in rabbits are typically subclinical…
Although fungal disease is uncommon in small mammals, dermatophytosis is the most common mycosis seen in clinical practice. Despite the low incidence of clinical disease, rodents are common asymptomatic carriers of dermatophytes. Fungal pathogens are generally more important for their zoonotic potential. Rodents are frequently asymptomatic carriers of ringworm, and transmission of disease to human caretakers is not uncommon.
The physical and psychological benefits of pet ownership have been well established, however pet ownership is not without risks such as the potential for transmission of zoonotic disease. Reptiles can carry a number of bacterial, fungal, protozoal, and parasitic pathogens including Salmonella spp. Approximately 6% of human Salmonella spp. infections are acquired from reptiles.
Tularemia is a highly pathogenic disease of animals and humans that has been reported throughout the northern hemisphere including North America, Europe, and Asia. In the United States, naturally occurring infections have been reported in all states except Hawaii.
The physical and psychological benefits of pet ownership have been well established, however close contact with pets is not without risks including the potential for transmission of zoonotic disease. Rodents can carry a number of potential pathogens including lymphocytic choriomeningitis virus. Lymphocytic choriomeningitis virus is found throughout the world in wild rodents. Disease is especially common in…
More than 200 diseases are zoonotic or common to animals and humans. Veterinary staff members are continually exposed to animals that potentially carry infectious disease. This risk is an acceptable one as long as the risk is known, understood, and preventive measures are taken. These preventive measures are fairly straightforward and include…
It is important for animal health care professionals to recognize the potential hazards of working with passerine birds so that appropriate measures can be taken to minimize the risk of contracting disease. Wild bird isolates of Salmonella enterica serotype typhimurium may not represent a large zoonotic risk to the general population, however the vast majority of sick and dying songbirds harbor this microbe.
Unlike many waterfowl species, Canada geese tend to travel further from water to feed. In turn, this allows birds to spread their feces over large areas. While feeding, one Canada goose can produce approximately one dropping per minute. Total daily fecal production may reach approximately 2 pounds or more of waste per goose.
October 21st is Reptile Awareness Day. Although Reptile Awareness Day was founded with the worthy goal of exploring the ecological challenges that reptiles face, celebrate with LafeberVet by taking our quiz that focuses on clinical information. Are you aware of these reptile-centric facts that will benefit you, your staff, and of course your reptile patients?
“Simply having a reptile in the household increases the risk of Salmonella spp. infection”. Learn who is most at risk and what you can do to minimize your family’s risk of contracting disease.
Psittacosis is an infectious disease of birds and people caused by Chlamydia psittaci, formerly known as Chlamydophila psittaci. This client education handout discusses types of birds commonly associated with human psittacosis, persons at risk as well as details of psittacosis in humans as birds and measures to prevent disease.

All mammals are considered to be susceptible to rabies although susceptibility appears to vary by species and viral variant. Rabies is exceedingly rare among small wild mammals and exotic pets. Among rodents in the United States, rabies is most commonly reported in…
Most species of mites are host-specific, however take special precautions, such as wearing exam gloves, to minimize the spread of potentially zoonotic pathogens. Humans that become infested with Sarcoptes scabei may develop wheals, vesicles, papules, and intense pruritus. Pet owners, especially children, may become infected with…
Neurologic diseases are relatively common in companion rabbits, and recognition of these conditions by the exotic animal clinician is very important. Encephalitozoonosis is endemic in the pet rabbit population worldwide, and is an important cause of neurologic disease in this species.
Fungi are among the most common causes of infectious disease in captive birds, and fungal diseases can be challenging to diagnose, as well as treat. Because fungi are typically opportunistic, causing non-contagious disease in susceptible individuals, prevention and treatment require an understanding of etiology as well as predisposing factors.
