Case Report: Two Cases of Ocular form of Listeriosis in Cattle Herds

Donachie 1997, Radostits et al. 2007), and an ocular form (uveitis, kerato-conjunctivitis, hypopion) (Welchman et al. 1997, Ravary 2000, Laven & Lawrence 2006, Radostits et al. 2007). Listeria has the particularity of forming micro-abscesses in organs. The nervous form is the easiest to diagnose due to its typical clinical pattern. However, the other clinical forms must not be under-estimated. For example, diagnosing the ocular form of listeriosis at herd level, could allow a prophylactic approach before confrontation with other clinical forms of the disease (Ravary 2000). The present case report shows how the ocular form of listeriosis can serve as a sentinel for the disease at a herd level.
