There is no vaccine available for use in sheep and other small ruminants. 60 day withdrawal. Chlamydiae are obligate intracellular bacteria that form inclusions within the cytoplasm of epithelial cells. Sequence analysis of the genome of C. abortus revealed highly variable protein families, including TMH (TransMembrane Head)/Inc and Pmps (Polymorphic Membrane Proteins). Their use may be considered in catteries where chlamydiosis is endemic. The information is written by veterinary experts, peer-reviewed and presented in a practical format with a high visual clinical content to improve disease awareness and highlight disease prevention.

Follicular conjunctivitis was described in a single immunocompromised person who was found to be infected with C felis. The results of this study indicate that the diversity of chlamydial infections in the eyes of sheep is quite broad with the identification of three different species of the family Chlamydiaceae (Cp.
