| prevalence of certain antibodies to selected disease-causing agents in wild turkeys in texas. | in texas in 1976 and 1977, rio grande turkeys (meleagris gallopavo intermedia) from seven counties and eastern turkeys (m. g. silvestris) from one county were tested for antibodies to selected poultry pathogens. standardized serological tests disclosed reactors to salmonella pullorum (2.4%), s. typhimurium (2.3%), and mycoplasma gallisepticum (4.8%). there were no reactors to newcastle disease virus or chlamydia psittaci. prevalence of m. gallisepticum antibody in wild turkeys was significantly ... | 1979 | 384989 |
| serological and microbial survey of mycoplasma gallisepticum in wild turkeys (meleagris gallopavo) from six western states. | from 1986 to 1989, sera from wild turkeys (meleagris gallopavo), including three subspecies (m. gallopavo intermedia, m. gallopavo merriami and m. gallopavo mexicana) trapped in six western states were tested for antibody to mycoplasma gallisepticum (mg) (n = 724), m. synoviae (ms) (n = 461) and m. meleagridis (mm) (n = 354) using the rapid plate agglutination (rpa) assay. subsamples of these sera were also evaluated using the hemagglutination inhibition (hi) assay for antibody to mg (n = 664) a ... | 1992 | 1548787 |
| mycoplasma gallisepticum infection in wild-type turkeys living in close contact with domestic fowl. | mycoplasma gallisepticum was isolated from 2 wild-type turkeys (meleagris gallopavo) and 1 domestic turkey living in close contact on a farm in tehama county, california. sinusitis was detected in 2 of 14 wild-type turkeys and in 1 of 12 feral broad-breasted bronze turkeys, but in none of several chickens on the premises. the entire mixed flock was captured, sinus aspirates were collected from affected birds, and blood samples were obtained from all birds for serologic testing. blood samples als ... | 1983 | 6643238 |
| infectious disease survey of rio grande wild turkeys in the edwards plateau of texas. | state wildlife agencies have translocated thousands of wild turkeys (meleagris gallopavo) since the 1930s to reestablish this species. because of threats to the domestic poultry industry and wild birds, screening for selected infectious agents has become routine since the early 1980s. one of the principal sources for rio grande wild turkeys (m. gallopavo intermedia) for translocation purposes was the edwards plateau of texas (usa). unfortunately, turkey abundance has declined in the southern edw ... | 2002 | 12528453 |
| infectious disease survey of lesser prairie chickens in north texas. | lesser prairie chicken (tympanuchus pallidicinctus) abundance, like that of most grassland birds, has declined rangewide for decades. although habitat loss and degradation are likely ultimate causes for this decline, infectious agents, particularly microparasites, could be proximate contributors. no surveys of pathogenic bacteria or viruses have been published for this species. we surveyed 24 free-living lesser prairie chickens from hemphill county, texas (usa), for evidence of exposure to salmo ... | 2002 | 12528454 |
