There are two types of people who will tell you that you cannot make a difference in this world: those who are afraid to try and those who are afraid you will succeed.

Our Services


Our state-of-the-art laboratory is equipped to handle various tests for bacteria and protozoa that are of paramount importance in veterinary medicine.


  • Brucellosis Testing: Accredited by SANAS, our laboratory performs the Rose Bengal Test to diagnose Brucellosis in cattle, a critical service given the disease’s impact on animal health and productivity.

To ensure accurate and timely diagnosis, we offer both culture-based methods and real-time PCR testing.
