Retrospective study investigating the seroprevalence of Anaplasma phagocytophilum in Manitoba, Canada: 2011-2014

Abstract

Human granulocytic anaplasmosis is currently not nationally notifiable in Canada. This for the most part accounts for gross under-estimation of true incidence and prevalence of HGA and would potentially culminate in clinical missed opportunities. To the best of our knowledge, this is the first report on the seroprevalence of Anaplasma phagocytophilum in a Canadian jurisdiction with known established black-legged tick populations.
