Acute diarrhea in dogs is a frequently encountered issue in small animal veterinary practice. While it is usually self-limiting and can be resolved with symptomatic treatment alone, antibiotics are often prescribed as part of the therapeutic management plan. In this webinar, we will discuss the common causes of acute diarrhea, including infectious agents, and highlight the importance of fecal analysis in identifying the underlying cause. We will also explore the appropriate usage of antibiotics in treating acute diarrhea and the potential adverse effects of antibiotic administration.


Dr. Sushant obtained his Ph.D. from National Tsing Hua University and Academia Sinica, Taiwan. He has expertise in biomarker discovery and protein structural biology with a strong research background in investigating potential biomarkers for target diseases. Currently, Dr. Sushant works as a diagnostic product specialist with Bioguard Corporation (Taiwan).

Pigeon Circovirus

Image description

Pigeon circovirus (PiCV) is an infectious disease that mainly affects young pigeons between 1 and 4 months of age. Mortality is variable, but it can approach 100%.

Pigeon circovirus infections have led to the loss of lymphoid tissue in immune system organs, and for this reason, PiCV is regarded as an immunosuppressive agent in pigeons.


Pigeon circoviruses, also known as columbid circovirus (CoCV), belong to the genus Circovirus in the family of the Circoviridae. They are small, non-enveloped viruses consisting of single-stranded circular DNA. Pigeon circovirus is antigenically distinct from psittacine beak and feather disease (PBFD) virus, which also belongs to the genus Circovirus, but does share some homologous.


The pigeon circovirus is transmitted mainly horizontally. Detection of the virus in the intestine, cloaca, and feces support fecal–oral route transmission. Also, inhalation of other fecal-contaminated materials, such as feather dust, has been suggested as a potential respiratory route of infection. Vertical transmission of PiCV is also possible by the detection of the virus in testis and semen samples of breeding cocks, the ovary but not in the oviduct of the hens, in embryonated eggs, and chicks recovered from eggs shortly before hatching.

Clinical signs and lesions

Image description

The clinical signs of PiCV infections in pigeons is highly varied. In pigeons between 1 and 4 months of age, circovirus infections are associated with lethargy, anorexia, ruffled feathers, dyspnea, diarrhea, and fluid-filled crop, also known as ‘young pigeon disease syndrome’ (YPDS). However, this syndrome should be considered a multifactorial disease. In most cases, concurrent infections can be demonstrated with all possible viral, bacterial, and parasitic agents hampering the assessment of the exact role of the circovirus.

The most obvious lesion is a swollen, edematous bursa in the acute phase of infection. However, more chronic infections result in atrophy of the bursa. Histological lesions consist of lymphocyte depletion in lymphoid tissue and characteristic intracytoplasmic basophilic inclusion bodies (mainly in macrophages) in the lymphoid tissue.

Diagnosis and Prevention

Before having the sequence of the pigeon circovirus, diagnosis of PiCV infections mainly depended on histopathological examinations and electron microscopy findings of the intracytoplasmic and/or intranuclear inclusion bodies in lymphoreticular and hepato-intestinal tissues. Since publication of PiCV sequence, the virus now can be detected by polymerase chain reaction (PCR), in situ hybridization, and dot blot analysis.

Currently, there is no specific treatment or effective vaccine against PiCV since pigeons infected with PiCV could die from secondary infections caused by the virus. At the moment, protection against potential detrimental effects of PiCV infection relies on good biosecurity measures in the loft.


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