Veterinary Virus Isolation and Cultivation
In the realm of veterinary medicine, infectious diseases caused by viruses have long posed a threat to the life and health of animals. The isolation and cultivation of viruses play a crucial role in the study and solutions of veterinary viral pathogens. It is essential for the development of effective diagnostics, treatment methods, vaccines, and preventive measures. As an expert in animal disease diagnostics, BioVenic is dedicated to providing comprehensive and custom veterinary virus isolation services to assist clients in addressing the primary challenges in virus research.
Veterinary Virus Isolation Services
Unlike many bacteria that can grow on artificial culture media, viruses require active host cells for replication. To obtain viruses, we help clients cultivate already infected eukaryotic or prokaryotic host cells and then collect the growth from the culture medium as the source of the virus. We can separate virus particles from the liquid culture medium and host cells through centrifugation or using a filter membrane with a pore size of 10-300 nm.

Veterinary Virus Cultivation Services
We provide clients with both in vitro and in vivo virus cultivation services to meet the specific growth requirements of various veterinary viruses.
- In Vivo Cultivation
Embryos or host animals serve as incubators for virus replication. Our in vivo cultivation services include embryo cultivation and host animal cultivation, with a focus on the tissue specificity of veterinary viruses to facilitate the introduction of the client's virus at specific sites.
Embryo Cultivation
In embryo cultivation services, we often provide chicken embryos as incubators for the virus. Chicken embryos are fertilized eggs developed into chicken embryos and are suitable for the isolation and cultivation of viruses such as avian influenza virus, poxvirus, and mumps virus. We inoculate the virus at specific locations within the chicken embryo, such as the amniotic cavity, chorionic membrane, or yolk sac, based on client requirements.
Host Animal Cultivation
We select common host animals such as model animals, dogs, bovines, pigs, etc., based on client requirements. The inoculation routes include intranasal, subcutaneous, intradermal, intracranial, intraperitoneal, and intravenous, among others. Our host animal cultivation services aim to assist clients in researching virus pathogenicity, identifying pathogens, and evaluating vaccines and new drugs.
- In Vitro Cultivation
In vitro cultivation of veterinary viruses requires tissue culture cells derived from animals. BioVenic utilizes both primary cells and continuous cell lines to assist clients in the in vitro cultivation of viruses.
Primary Cell Culture
Primary cell culture involves using cells freshly prepared from animal organs or tissues for the cultivation of viruses. In this process, cell density is controlled through contact inhibition, allowing cells to adhere to the surface of the culture vessel. Through primary cell culture, we can provide virus cultivation services that adhere to high-quality standards.
Secondary Cell Culture
Secondary cell culture refers to the continuous passage of cells in vitro, mostly derived from tumor tissues or diploid cells, allowing the virus to undergo multiple passages or unlimited growth. This service aids clients in cultivating suspension-grown cells, enabling cells to sustain continuous growth like small tumors. This provides flexibility and sustainability for the in vitro cultivation of viruses.
