Abundance and Distribution of Rickettsial Gene Targets across Collected Ixodes scapularis Ticks
Stage | Count of Ticks Collecteda | % (count) of gltA+ Ticks | Mean Copies of gltA Per ng DNAb | Count of Ticks Tested for RAGEs A and B | % (count) of gltA+ sis6−pks1+ Ticks | % (count) of gltA+ sis6+ pks1− Ticks | % (count) of gltA+ sis6−pks1− Ticks |
---|---|---|---|---|---|---|---|
Female | 78 | 95% (74) | 366.2* | 60 | 5% (3) | 25% (15) | 5% (3) |
Male | 17 | 76% (13) | 166.9* | 6 | 0% (0) | 0% (0) | 0% (0) |
Nymph | 35 | 49% (17) | 103.6* | 15 | 20% (3) | 13% (2) | 7% (1) |
Note.—The percentage of gltA+ ticks (column 3) and mean copies of gltA per ng DNA (column 4) were calculated from the total number of collected ticks (column 2). All other percentages were calculated from the number of ticks tested for RAGEs A and B (column 5).
Samples without measurable DNA are not included in these counts.
Samples with gltA copy number <10 were considered gltA−.
Denotes a lack of significance (p < 0.05) between labeled groups, according to analysis of variance (see main text for details).
