Introduction:

The identification of microorganisms of intentional manipulation is essential for the design of an epidemiological surveillance process associated with biological risk in laboratories.

Objective:

To determine the microorganisms associated with the presence of signs and symptoms in laboratory workers of a university institution in a city of eastern Colombia.

Material and Methods:

Descriptive cross-sectional study carried out in 33 laboratories and 24 workers.

Results:

risk association of presenting headache when handling Oscillatoria spp p=0.09 and RR=2.0 (IC95% 1.29-3.1), pharyngitis with fungi of the genus Aspergillus spp and Fusarium spp p≤0.05 RR=10.0 (IC95% 1.39-71.86) and allergic rhinitis when handling Staphylococcus aureus p≤0.05 and RR=2.3 (IC95% 1.05-5.17)

Conclusions:

Laboratory-acquired infections are identifiable if protocols and information on intentional and unintentional handling microorganisms are maintained, being the beginning of the epidemiological surveillance process associated with biological risk.
