Reservoir competency of goats for Anaplasma phagocytophilum.
The susceptibility of goats to infection by Anaplasma phagocytophilum (A. phagocytophilum) strains Ap-Variant 1 and Ap-ha was assessed by infestation of goats with field-collected Ixodes scapularis (I. scapularis) ticks. Both strains were infectious in the goat model. These results demonstrate that goats can be used in a laboratory setting to propagate A. phagocytophilum. Transmission from an infected goat to a naïve goat by I. scapularis tick feeding was used to demonstrate that goats are reservoir-competent for the Ap-Variant 1 strain.
