| legionnaires' disease in pneumonia patients in iowa. a retrospective seroepidemiologic study, 1972-1977. | the frequency of legionnaires' disease among 586 cases of pneumonia that occurred in iowa between fiscal years 1972 and 1977 was studied retrospectively on the basis of paired sera. the frequency of confirmed legionnaires' disease was 4.1% and of presumptive legionnaires' disease was 11.4%. infections with the legionnaires' disease (ld) bacterium were most frequent in the summer. of the 22% of pneumonias for which a cause could be defined, legionnaires' disease was third in frequency behind myco ... | 1979 | 434644 |
| prevalence of antibodies to mycoplasma hyopneumoniae in iowa swine. | the prevalence of complement-fixing antibodies to mycoplasma hyopneumoniae was determined in 7,321 sera collected from breeding swine of various ages. samples were selected randomly in approximate proportion to the number of hogs marketed annually from each of 9 crop-reporting areas in iowa. testing was accomplished by means of a microtiter complement-fixation test. of the 7,321 sera, 22% had antibody titers of 1:4 or greater to m hyopneumoniae. of the 597 herds sampled, 60% or 357 had at least ... | 1983 | 6638651 |

| outbreak of mycoplasma iowae infection in commercial turkey poults. | in september 1989, 17-day-old turkey poults were submitted to iowa state university because of leg weakness and dehydration. these birds were commercial large white toms from a flock of 23,214. lesions observed at necropsy included chondrodystrophy of the hock joints, clear fluid in hock joint spaces, valgus deformities and shortening of the tarsometatarsal bones, and curled toes. mycoplasma iowae was isolated and identified from swabs of the air sac, cloaca, hock joint, and large intestine. app ... | 1994 | 7702529 |
| differential serologic response to mycoplasma ovipneumoniae and mycoplasma arginini in lambs affected with chronic respiratory disease. | an enzyme-linked immunoabsorbent assay (elisa) was used to evaluate the levels of antibodies to mycoplasma ovipneumoniae and m. arginini in lambs with chronic respiratory disease. sera were obtained from lambs in several flocks at various stages of the clinical disease and tested with sodium dodecyl sulfate (sds)-treated m. ovipneumoniae and m. arginini whole cells and a crude capsular extract of m. ovipneumoniae as the antigens. there were low levels of antibody to m. ovipneumoniae in flocks sa ... | 1999 | 9925209 |
| increased prevalence of torque teno viruses in porcine respiratory disease complex affected pigs. | the role of swine torque teno sus viruses (ttsuvs) as co-factors in disease syndromes involving porcine circovirus strain 2 (pcv2) and porcine reproductive and respiratory disease syndrome virus (prrsv) has been a debatable subject. in this study, the prevalence of ttsuvs in iowa, the leading pork producing state in the u.s., was estimated by a duplex pcr. the pcr is capable of simultaneously detecting both teno sus viruses 1 and 2 (ttsuv1 and 2). based on an analysis of 300 random samples repre ... | 2011 | 22227415 |
| sporadic legionnaires' disease: clinical observations on 87 nosocomial and community-acquired cases. | to add information about sporadic legionnaires' disease, 87 cases of l. pneumophila pneumonia were reviewed. twenty cases were nosocomial infections and 67 cases were community-acquired. most cases (64%) occurred between july and october. the mean age of patients was 51.4 years and males outnumbered females 2.5:1.0. thirty-one percent of patients were receiving corticosteroid, immunosuppressive, or antineoplastic chemotherapy when illness began. immunosuppression at onset of illness was more com ... | 1984 | 6465187 |
| isolation and identification of mycoplasma agalactiae subsp. bovis from arthritic cattle in iowa and nebraska. | two strains of mycoplasma were isolated from synovial fluids of arthritic feeder cattle and were identified as mycoplasma agalactiae subsp. bovis by growth inhibition and fluorescent antibody tests. the strains (iowa 1136 and nebraska 2) could not be distinguished from known strains (donetta and california 01) by immunoelectrophoresis or by agar gel precipitation. | 1975 | 1176624 |
