Webinar: Clinical Interpretation of Liver Function Tests

Image description

A free online class brought to you by Bioguard

Get familiar with the biomarkers for liver function. 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 testing in dogs and cats is a crucial clinical assay utilized to assess the hepatic health status of these animals. The liver plays multiple essential roles in the physiological processes of dogs and cats, including metabolism, regulation of excretion, modulation of immune responses, protein synthesis, and energy storage. Therefore, comprehending and monitoring the liver function in dogs and cats is paramount for ensuring their overall health.

In this lecture, we'll explore Biochemical Blood Markers, Blood Coagulation Indices, Blood Urea Nitrogen (BUN) and Creatinine, and Blood Glucose Levels. Through these tests, clinicians can formulate appropriate treatment plans to guarantee dogs' and cats' long-term health and well-being.


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.

Psittacosis in Birds


Psittacosis (parrot fever), also known as ornithosis, is a bacterial zoonotic disease caused by the bacterium Chlamydia psittaci. It is usually spread by exposure to infected birds at home, pet stores, pigeon stalls and other locations where birds are kept or displayed. The disease was first reported in Switzerland in 1879, and then occurred successively in Britain, Europe, USA, Central and South America and other regions. The incubation period varies from 5-28 days. The clinical symptoms are nonspecific and may include fever, chills, headache, muscle aches and cough.

Chlamydia psittaci includes six avian (A–F) and two mammalians (WC in cattle and M56 in muskrat) serotypes with distinct host specificity, based on serotyping using monoclonal antibodies in the 1990s. Different serotypes have been isolated from different avian species like serotype A in psittacine birds, B and C in both ducks and geese, D in turkeys, E mainly in pigeons (also in other avian species), and F in parakeets and turkeys. Serotype A is often reported in human zoonotic cases.

Based on recent genotypic classification, C. psittaci has several classical genotypes with relevant host specificity. The genomic sequence encoding the outer membrane protein (ompA) is used to classify genotypes, which are employed to study isolates from infected birds and isolates in mammals. All identified genotypes are considered capable of transmission to humans.


Infected birds may shed C psittaci in their droppings, saliva, mucus, feather dust and eye/nasal discharge. Healthy birds may then inhale this bacteria in airborne particles, such as dust from dried droppings and feathers. Birds may also ingest C psittaci from contaminated food, water, perches, and toys. Some infected birds don't show any sign of illness. However, they may become ill and shed the bacteria during times of stress (e.g., battling another infection, changing diet, or living in a crowded environment). Humans most commonly catch the disease from infected birds by breathing in the dust from shed feathers, secretions, and droppings. Less commonly, birds infect people through bites and beak-to-mouth contact.

Clinical symptoms

The incubation time for infected birds is about 3 days to several weeks up to a month. In birds, the symptoms include poor appetite, ruffled appearance, eye or nose discharge, green or yellow-green droppings, and diarrhea (loose droppings). Occasionally, birds may die from the disease. Some birds may shed the bacteria while exhibiting only mild or no symptoms. C. psittaci may affect some or all of a bird's organ systems, most commonly the liver, spleen, respiratory tract and digestive tract.


Since psittacosis symptoms can look like an array of other diseases in birds, special tests are needed to diagnose the presence of C. psittaci. Methods to diagnose chlamydial infections include:
Antigen detection- immunohistochemistry, immunofluorescence test and ELISA
Serology- complement fixation, ELISAs, and indirect immunofluorescence test
Molecular diagnosis- PCR


Treatment is usually with oral or injectable doxycycline antibiotic. Since doxycycline only kills the Chlamydia organisms when they are active and dividing, and the lifecycle of these organisms is prolonged, with possible periods of dormancy (ceasing to be active for a period of time), drug treatment should go on continuously for the recommended period of 45 days, without interruption.
