Caseous Lymphadenitis (CLA), a contagious disease caused by Corynebacterium pseudotuberculosis (C. pseudotuberculosis) threatens animal and economic health of small ruminants population worldwide. The disease is complicated by abscesses formation on lymph nodes and internal organs and results in lower productivity, low veterinary costs due to the necessity of removing affected animals. This is because a number of measures needs to be put in place to avoid introducing and spreading CLA within herds. This review focuses on several aspects of biosecurity measures to provide protection from disease through immunization. The biosecurity preventing CLA relies on early diagnosis, other ways of isolation of infected animals and strict management of the environment. The review also explains the difficulty of applying these measures in areas with limited resources and emphasizes raising awareness and stepping up education and collaboration among the staff of veterinary offices, farmers and other stakeholders to control CLA in small ruminants.
