serologic survey for toxoplasma gondii in wild animals in florida.blood samples were collected for serum separation from 114 species of wild animals (25 species of mammals, 82 species of birds, and 7 species of reptiles) in florida. each of the 3,471 samples was tested for antibodies to toxoplasma gondii, using the indirect hemagglutination test. the highest prevalences of t gondii antibodies were 19% in armadillos (dasypus novemcinctus), 18% in raccoons (procyon lotor), 13% in black rats (rattus rattus), and 11% in opossums (didelphis marsupialis). antibody p ...1979521384

black creek canal virus infection in sigmodon hispidus in southern florida.a total of 1,500 small mammals were collected and tested for antibodies cross-reactive to sin nombre virus (hantavirus: bunyaviridae) at 89 sites in a 1,600 km2 study area of southern florida. more than 95% of the 123 seropositive animals were cotton rats (sigmodon hispidus), suggesting infection by black creek canal virus, although seroreactive rattus rattus (5 of 294) and peromyscus gossypinus (1 of 39) also were captured. crude seroprevalence in s. hispidus was 11%. seroprevalence increased w ...19989840584
