* Percent of rodents positive for ELISA antibody using PH antigen/total number of specimens tested. Almost all specimens also tested with SEO and PUU antigens. With two exceptions, PH antigen gave a higher percent positive reactions than the other two antigens. The following rodent species (number tested vs PH antigen) were negative for ELISA antibody for either PH and SEO or, PH, SEO and PUU antigens. Peromyscus nasutus (10), Peromyscus crinitus (1), Ammospermophilus leucurus (14), Cynomys gunnusoni (1), Dipodmys merriami (4), Dipodomys ordii (6), Dipodomys species (1), Microtus longicaudus (2), Microtus mexicanus (1), Microtus montanus (2), Microtus pennsylvanicus (4), Neotoma mexicana (20), Neotoma micropus (4), Neotoma stephansi (6), Neotoma species (2), Onychomys leucogaster (10), Onychomys species (2), Perognathus flavus (5), Perognathus species (2), Sigmodon hispidus (6), Spermophilus spilosoma (4), Spermophilus tridecemlineatus (7), Spermophilus lateralis (2). |
