| 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 |
| observations on the involvement of wildlife in an epornitic of chlamydiosis in domestic turkeys. | in an investigation of potential wildlife reservoirs of chlamydia psittaci at the site of an acute, highly fatal epornitic of chlamydiosis in domestic turkeys in texas, various species of wild birds and rodents were captured and tested for chlamydial serum antibodies and chlamydiae in their tissues. thirteen (65%) of 20 blackbirds (agelaius sp), 4 (44%) of 9 killdeer (oxyechus vociferus), 3 (27%) of 11 sparrows (passer sp) and 1 of 4 mourning doves (zenaidura macroura) were seropositive, but chl ... | 1976 | 988009 |
| chlamydiosis in captive white-winged doves (zenaida asiatica). | chlamydia psittaci was isolated from the spleen of a moribund white-winged dove (zenaida asiatica). the isolate was serotyped as the serovar b that is commonly isolated from pigeons. a fourfold increase in the titer of antichlamydial igm activity occurred in that bird in paired serum samples tested by chlamydial elementary body agglutination (eba) and a greater than or equal to fourfold decrease of igg occurred by direct complement fixation (dcf). the increases or decreases of eba and dcf titers ... | 1997 | 9201425 |

| 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 |
