22: 324-328) reported that, in addition to domestic turkeys, the bobwhite (Colinus virginianus) was susceptible to P. hermani and that only transient infections were produced in a domestic gosling (Anser anser) and in a canary (Serinus canaria). Whereas the ranges of knots and wild turkeys do not overlap in Florida, other scolopacids such as greater yellowlegs (Totanus imelanoleucus), lesser yellowlegs (Totanus flavipes), spotted sandpipers (Actitis uiaciularia), and semipalmated sandpipers (Ereunetes pusillus) are found in relatively close association. The role of these birds in the epizootiology of wild turkey malaria is unknown. Natural infections of Plasmodium have been reported in only five of 1,159 scolopacids examined by blood smear in North America (Greiner et al., 1975, Can. J. Zool. 53: 17621787), but infection rates may have been somewhat higher if isodiagnostic techniques such as described by Herman et al. (1966, Avian Dis. 10: 541-547) and Forrester et al. (1974, J. Protozool. 21: 494-497) were employed. In general, this family and other charadriiforms appear rarely to be infected with hematozoans (Greiner et al., 1975, op. cit.; White et al., 1978, Rev. Biol. Trop. 26: 43102; McClure et al., 1978. Haematozoa in the birds of' eastern and southern Asia, Memorial University of Newfoundland, St. John's, 296 p.). This may be the result of ecological isolation of the vectors from these hosts rather than insusceptibility to Plasmodium. These findings show that the knot is sutsceptible to blood-induced infections of P. herimauti. The parasitemias were considerably higher than those induced experimentally in domestic and wild turkey poults (Forrester et al., 1980, J. Wildl. Dis. 16: 237-244). This may be a reflection of differences in innate host susceptibility, but it is possible that the high parasitemias resulted from the effect of the concurrent Besnoitia-like infections.
