Listeria associated mural and valvular endocarditis in an alpaca.
ABSTRACT An alpaca presented for emergency evaluation of respiratory distress. Physical examination revealed weakness, pyrexia, and a grade V/VI left apical holosystolic murmur. Initial thoracic examination and radiographs were consistent with left sided congestive heart failure. Blood cultures, echocardiographic evaluation, and necropsy findings established a diagnosis of bacterial endocarditis associated with a Listeria monocytogenes infection. Left ventricular endocarditis is uncommon in ruminants, and to the authors' knowledge there are no other reports of L. monocytogenes being the causative agent in an alpaca.

ABSTRACT: Cardiovascular disorders, although not thoroughly described in the literature, are frequently diagnosed in South American camelids, causing morbidity, mortality, and loss of production. Definitive confirmation concerning the heritability of cardiac defects in these species is lacking; however, this potential exists and should be taken into account when counseling breeders and owners. This article describes the diagnosis and treatment of cardiovascular diseases in llamas and alpacas and reviews the most recent literature. Unique aspects of the cardiovascular physiology in these species are also reviewed.Veterinary Clinics of North America Food Animal Practice 08/2009; 25(2):423-54.

ABSTRACT: Severe endocarditis with myonecrosis, moderate to severe pleural and pericardial effusions, and mild ascites were found on necropsy in 3 alpacas. Mycoplasma hominis ssp. was detected on polymerase chain reaction (PCR) of fresh affected endocardial tissue in 1 alpaca.
