| a survey of infectious diseases in wild turkeys (meleagridis gallopavo silvestris) from arkansas. | wild turkeys (meleagridis gallopavo silvestris) trapped as part of a relocation program by the arkansas game and fish commission were tested for selected infectious diseases and parasites. the 45 birds were trapped at four locations in pope, scott, and montgomery counties (arkansas, usa). forty-four blood samples for serology, 27 blood smears and 12 fecal samples were collected. of the serum samples tested, 20 of 44 (45%) were positive for pasteurella multocida by enzyme-linked immunosorbent ass ... | 1990 | 2250323 |
| mycoplasmal infections of cerebrospinal fluid in newborn infants from a community hospital population. | mycoplasma hominis or ureaplasma urealyticum have previously been isolated from cerebrospinal fluid (csf) in 13 of 100 newborn infants tested from a high risk university hospital population where the mothers were of predominantly lower income and socioeconomic status and had often received little or no prenatal care. we sought to determine whether such infections occur in neonates born to women cared for mainly through private obstetric practices and who delivered in 4 suburban community hospita ... | 1990 | 2336309 |
| isolation of mycoplasma flocculare from swine in the united states. | during 1977 to 1980, mycoplasma flocculare was isolated from the lungs of 7 swine in the united states. two of the swine were from a single alabama herd, 1 was from minnesota, 2 were from different illinois herds, and 2 were from different indiana herds. three of the swine were from specific-pathogen-free herds and 4 were from conventional herds. the lungs from the 7 swine had gross lesions typical of mycoplasmal pneumonia. two lungs yielded a mixture of m flocculare and m hyopneumoniae; the rem ... | 1981 | 7283233 |
| characterization of the mycoplasmal conjunctivitis epizootic in a house finch population in the southeastern usa. | an epidemiological study of the prevalence of mycoplasmal conjunctivitis in the house finch (carpodacus mexicanus) was conducted in auburn (alabama, usa) between march 1998 and february 1999. clinical disease was observed in 4% of the 1,214 finches trapped and examined. this rate is comparable to the average annual prevalence observed in this population since 1996, although the prevalence of clinical disease observed in the peak months of september through november was lower than in previous yea ... | 2001 | 11272508 |
| characterization of mycoplasma gallisepticum infection in captive house finches (carpodacus mexicanus) in 1998. | since 1995, the epidemic of mycoplasmal conjunctivitis in eastern house finches has affected the auburn, al, house finch population. to better characterize the current status of this host-parasite interaction, we established a captive flock of 38 seronegative, healthy finches in fall 1998. after a minimum quarantine period of 4 wk, two mycoplasma gallisepticum (mg)-infected house finches were introduced into this flock. over a 12-wk period, the flock was captured every 2 wk and each bird was obs ... | 2001 | 11332501 |
| use of a polymerase chain reaction assay to detect infection with eperythrozoon wenyoni in cattle. | to determine whether a polymerase chain reaction (pcr) assay could be used to detect eperythrozoon wenyoni in the blood of cattle. | 2001 | 11724184 |
| susceptibility of a naïve population of house finches to mycoplasma gallisepticum. | since 1994 an epidemic of mycoplasmal conjunctivitis has spread throughout the eastern house finch (carpodacus mexicanus) population leading to a significant decline in this population. the infection has not yet been reported from house finch populations west of the great plains. we hypothesized that the western population, like the eastern population, is susceptible to infection, and we tested this hypothesis by experimentally infecting house finches from missoula, montana (usa) with the house ... | 2002 | 12038126 |
| the effect of mycoplasmosis on carotenoid plumage coloration in male house finches. | parasites are widely assumed to cause reduced expression of ornamental plumage coloration, but few experimental studies have tested this hypothesis. we captured young male house finches carpodacus mexicanus in alabama before fall molt and randomly divided them into two groups. one group was infected with the bacterial pathogen mycoplasma gallicepticum (mg) and the other group was maintained free of mg infection. all birds were maintained through molt on a diet of seeds with tangerine juice added ... | 2004 | 15143143 |
| pigeon paramyxovirus: association with common avian pathogens in chickens and serologic survey in wild birds. | pigeon paramyxovirus-1 (ppmv-1) was isolated from pigeons from east-central alabama and used in association with chicken anemia virus (cav), infectious bursal disease virus (ibdv), or finch mycoplasma gallisepticum (mg) in specific-pathogen-free chickens to assess dinical disease and pathology. ppmv-1 infection in all groups was conducted at day 10 of age via the ocular route. the low passage ppmv-1 isolate was inoculated into chickens in different groups at 10 days post-cav infection, 6 days po ... | 2005 | 15839419 |
| prevalence of bartonella species, haemoplasma species, ehrlichia species, anaplasma phagocytophilum, and neorickettsia risticii dna in the blood of cats and their fleas in the united states. | ctenocephalides felis were killed and collected from 92 cats in alabama, maryland, and texas. the fleas and blood from the corresponding cat were digested and assessed in polymerase chain reaction assays that amplify dna of ehrlichia species, anaplasma phagocytophilum, neorickettsia risticii, mycoplasma haemofelis, 'candidatus m haemominutum' and bartonella species. dna consistent with b henselae, b clarridgeiae, m haemofelis, or 'candidatus m haemominutum' was commonly amplified from cats (60.9 ... | 2006 | 16290092 |
| the alabama preterm birth study: intrauterine infection and placental histologic findings in preterm births of males and females less than 32 weeks. | the objective of the study was to determine whether there are differences in the placental histology and various markers of infection/inflammation between preterm male and female fetuses. | 2006 | 16796981 |
| the alabama preterm birth study: diffuse decidual leukocytoclastic necrosis of the decidua basalis, a placental lesion associated with preeclampsia, indicated preterm birth and decreased fetal growth. | laminar necrosis, a band-like distribution of coagulative necrosis, has been reported at the choriodecidual interface of the free membranes of placentas of women with various adverse neonatal outcomes. our goal in this study was to evaluate the frequency of an equivalent feature in the decidua basalis, diffuse decidual leukocytoclastic necrosis (ddln), a diffuse coagulative necrosis admixed with karyorrhectic debris, in preterm births <32 weeks, and to determine its association with various obst ... | 2007 | 17674243 |
| the alabama preterm birth study: umbilical cord blood ureaplasma urealyticum and mycoplasma hominis cultures in very preterm newborn infants. | this study was undertaken to evaluate the frequency of umbilical cord blood infections with ureaplasma urealyticum and mycoplasma hominis in preterm 23- to 32-week births and to determine their association with various obstetric conditions, markers of placental inflammation, and newborn outcomes. | 2008 | 18166302 |
| rapid evolution of disease resistance is accompanied by functional changes in gene expression in a wild bird. | wild organisms are under increasing pressure to adapt rapidly to environmental changes. predicting the impact of these changes on natural populations requires an understanding of the speed with which adaptive phenotypes can arise and spread, as well as of the underlying mechanisms. however, our understanding of these parameters is poor in natural populations. here we use experimental and molecular approaches to investigate the recent emergence of resistance in eastern populations of north americ ... | 2011 | 21525409 |
