RESUMO
Cattle, horses, sheep and goats in all areas of St. Lucia were examined to ascertain the prevalence and distribution of streptothricosis on the island and to investigate its association with the occurrence of Amblyomma variegatum ticks. Although the disease was found to occur throughout St. Lucia it was more prevalent and generally of a more severe form in areas where A. variegatum ticks are present. A tick control programme in the north of the island appeared to have resulted in a dramatic reduction in the prevalence of the disease. (AU)

The association between the occurrence of Amblyomma variegatum ticks and streptothricosis was higher on animals having A. variegatum ticks compared to that of animals not infested with A. variegatum ticks. There was a steady increase in the prevalence of severe lesions as the level of infestation with adult A. variegatum ticks increased. However the distribution of skin lesions could not be related to the predilection feeding sites of adult A. variegatum ticks (Summary)
