The CBMR/UAlg Vivarium is a conventional equipment used to house laboratory animals of the mus musculus species under specific pathogen-free conditions (SPF).

Experimentation on small rodents is an extremely valuable tool to the scientific process, which is greatly important to preclinical phases, used to conduct safety tests and evaluate drug efficacy. Currently, even with the most advanced technology, it is not possible to reproduce the complexity of the interactions between cells, tissues and organs that occur in humans. In the context of understanding these interactions and facilitating the development of new therapies, the scientific methodology elects animals, mostly rodents, as an experimental model for humankind. High genetic homology with humans, ease of genetic manipulation, short gestation periods and short life cycles make rodents an excellent research tool.

Progress in biomedicine is dependent on innovation and the translation of laboratory findings into clinical practice. In the process of biomedical research, animal experimentation is generally a prerequisite for the validation of scientific hypotheses and a mechanism that will allow patients to benefit from new therapeutic applications.

The CBMR-UAlg Vivarium follows the rules contained in Decree-Law No. 113/2013 and statements issued by ORBEA, as per in regulation No. 806/2016.


Biotério aims to provide technical and scientific support to UAlg researchers to use animal models in their experiments. All activity is carried out in accordance with the Portuguese Regulation for Animal Welfare. The Vivarium also aims to contribute to the training and competence training in experimental procedures in vivo, to CBMR researchers, students and medical staff of CHUA and other individual or collective persons.

Homemade breeding of a small number of “pure” lines of mice, namely C57 / Bl6 and 129 / Sv.

Breeding and housing of strains of genetically modified mice.

Execution of surgical procedures aimed at improving the health status of the animals housed and assistance in the import / export of animals, according to the SPF status of the receiving animal facility.

Technical and scientific advice to researchers planning to design genetic manipulation experiments using mouse models.


Biomedical, pharmacological, toxicity studies, etc. for external entities, upon request and contract.


Live image of small animal models, allowing visualization of anatomical structures and hemodynamic functions in vivo.

The UAlg Vivarium has a live imaging unit (High Frequency Ultrasound System).

The high-frequency ultrasound system provides high-resolution images of small animal models to visualize anatomical structures and hemodynamic functions in vivo, longitudinally, in a non-invasive manner.

The main areas of application are: cardiovascular research, cancer research, abdominal imaging, inflammation, reproductive biology, neurobiology, embryonic development, ophthalmology, tissue and stem cell regeneration.

The available techniques are:


  • Visualization and measurement of 2D and 3D anatomical structures 
  • Blood flow analysis
  • Image-guided injection and biopsies.
  • Contrast image to quantify the relative perfusion and study the expression of biomarkers.
  • VevoStrain analysis software for cardiac research.
