Webinar: Liver Function Testing

Image description

A free online class brought to you by Bioguard

Get familiar with liver function testing in dogs and cats. Sponsored by Bioguard Corporation and presented by Dr. Chen-Si Lin, this is the next webinar you don't want to miss it.

Access to the on-demand recording is FREE

Obtain a CERTIFICATE of attendance



Liver function tests in dogs and cats, including liver enzymes (ALT, AST, ALP), cholesterol, and bile acids, are key for evaluating liver health and diagnosing diseases. Elevated liver enzymes suggest hepatocellular damage or biliary obstruction. Abnormal cholesterol levels can indicate impaired liver function, while increased bile acids suggest hepatic insufficiency or cholestasis. Together, these tests are crucial for identifying liver diseases, enabling early intervention and management for better patient outcomes.


Dr. Lin got her D.V.M. degree from National Taiwan University and his Ph.D. from the College of Biological Science and Technology, National Chiao-Tung University. She is a professor in the Department of Veterinary Medicine and director of Zoonosis Research Center, National Taiwan University. In addition, she is a former director of the Animal Disease Diagnostic Center, National Taiwan University. Her specialties include Veterinary Clinical Microbiology, Immunology, and Animal Cancer Biology and Therapeutic Development.

Rabbit Hemorrhagic Disease

Image description

Rabbit Hemorrhagic Disease (RHD) is a fatal viral infection, caused by a virus belonging to the Caliciviridae family, that primarily affects European rabbits (Oryctolagus cuniculus), impacting both domestic and wild populations. The emergence of a newer strain, RHDV2, has expanded its reach, affecting rabbits previously immune to RHD and now includes hares (Lepus spp.).

The disease's first recorded outbreak traces back to China in 1984, following the importation of Angora rabbits from Germany, resulting in the death of approximately 140 million domestic rabbits within a year. The disease then spread internationally, reaching Korea through rabbit fur 

imports from China, and by 1986, had made its way to Italy, subsequently spreading across Europe. The Americas experienced their first outbreak in 1988 in Mexico, linked to rabbit products imported from China, though Mexico successfully curbed the disease by 1992. Today, RHD remains a threat in regions inhabited by European rabbits, causing deadly outbreaks across almost all continents.

Rabbit Hemorrhagic Disease Virus (RHDV) can be transmitted through oral, nasal, conjunctival, and parenteral routes, with blood-feeding insects identified as effective mechanical vectors for the disease. Transmission can occur directly through contact with an infected rabbit, which may release the virus via its secretions and excretions. Indirect transmission is also possible through contaminated objects such as food, bedding, water, clothing, cages, and equipment, or via vector-borne pathways involving scavenging mammals, birds, and insects. The primary entry points for the virus are believed to be within the upper respiratory and digestive tracts. In natural settings, the fecal-oral route is considered the most common pathway for spreading the disease.

Clinical signs

All domestic rabbits (Oryctolagus cuniculus) are at risk of RHD infection. RHDV2 poses no risk to humans, livestock, or other pets. There are four primary infection forms of RHD, each displaying similar clinical signs that do not vary significantly across different viral strains. In the extremely rapid peracute form, rabbits often show no clinical signs until terminal vocalizations, collapse, and death occur within 12 to 36 hours.

The slightly slower acute form can exhibit a broader spectrum of symptoms, including bleeding from the mouth, nose, or rectum, fever, difficulty breathing, eye hemorrhages, bloody feces, and jaundice due to anemia and coagulation issues triggered by the virus. The subacute form presents with the same symptoms but in a milder form, offering a chance of survival. Neurological symptoms may include loss of coordination and seizures, along with depression, lethargy, and decreased appetite.


Diagnosis of rabbit hemorrhagic disease is typically confirmed by performing a post-mortem examination, revealing characteristics such as an enlarged and pale liver indicative of the disease. For living rabbits, molecular diagnostic techniques like PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) can be utilized to confirm the presence of the virus. It's important to note, however, that some of these tests might not differentiate between the original RHDV strain and its variant, RHDV2.

Treatment and Prevention

At present, rabbit hemorrhagic disease has no cure. While supportive care can offer some help, prevention through vaccination is the most effective strategy. Hyperimmune antiserum might work if administered before clinical signs develop, but it becomes ineffective once symptoms are present. Vaccination is a viable preventive measure for domestic rabbits. However, due to the vast population of wild rabbits, vaccinating them is currently not economically viable.


Bioguard’s Qmini PCR can detect RHDV DNA in 90 minutes at your clinics using blood as samples.
