Red counties experienced at least one positive sample, with the year that positive sample was collected indicated. White counties were not tested. (MP-12) challenge, as well as previous cross-reactivity assessments,9 suggests that serum neutralization is usually a specific test for HRTV. Ecological factors that affect tick populations, such as temperature, humidity, foliage types, and other mammalian hosts, may influence where WTD are likely to be exposed to HRTV, leading to clustering of positive samples. Biases may also be present in which deer were sampled because there were significantly more females than males represented and more deer over 1 year of age. More consistent sampling of WTD for HRTV-neutralizing antibodies may elucidate other factors of viral ecology and transmission and may better characterize Methionine the magnitude and duration of the humoral response in WTD. There was a significant association with moderate and heavy tick burdens and HRTV seropositivity, which is usually consistent with other evidence of being the primary vector for HRTV.5C7 In addition, HRTV-exposed deer have been detected in most of the says where human cases of HRTV-associated disease have been documented. The presence of seropositive and tick-laden WTD in an area may be another useful indication for the presence or increased blood circulation of HRTV in a given area, alerting human health providers and specialists to the potential of human HRTV infections.
