Protection in alpacas against Corynebacterium pseudotuberculosis using different bacterial components.

Corynebacterium pseudotuberculosis is a Gram positive bacterium that produces caseous lymphadenitis in sheep and goats, and a granulomatous lymphadenitis in llamas and alpacas. To evaluate the immune potential of different doses of cell wall and toxin components of C. pseudotuberculosis from alpaca origin, 12 adult alpacas were allotted at random to four groups, and SC inoculated in the left flank with vaccines composed of low and high doses of bacterial crude antigens, cell wall: 250 and 500 microg/ml and toxin: 133 and 265 microg/ml, respectively.

Clinical, humoral, and pathologic findings in adult alpacas with experimentally induced Corynebacterium pseudotuberculosis infection.

Objective: To experimentally infect adult alpacas by ID inoculation of Corynebacterium pseudotuberculosis, follow the clinical and pathologic course of disease, and study the humoral response to infection.

Animals: 13 adult alpacas.

Procedures: 9 alpacas were inoculated with 1.
