    “Despite the efficacy of intralesional and parenteral administration of tulathromycin and oxytetracycline in many CL cases, recurrence remains a problem. Therefore, these drugs cannot be considered curative; however, they can be an acceptable alternative for managing cases of CL when culling from the herd or flock is not acceptable to the owner.”

    The internal form of CL usually presents as chronic weight loss and failure to thrive. The presence of other clinical signs depends on the organs of involvement, which may include any of the major organ systems.

    Lung abscessation is a common form of visceral involvement in internal CL; therefore, signs of chronic ill thrift with cough, purulent nasal discharge, fever, and tachypnea with increased lung sounds may be noted. The internal form is more common in sheep and has been termed “thin ewe syndrome.”

    The incidence of abscesses and development of clinical signs with either the external or internal form of CL increase with age.”
