| an annotated checklist of pathogenic microorganisms associated with migratory birds. | the potential for transport and dissemination of certain pathogenic microorganisms by migratory birds is of concern. migratory birds might be involved in dispersal of microorganisms as their biological carriers, mechanical carriers, or as carriers of infected hematophagous ecto-parasites (e.g., ixodid ticks). many species of microorganisms pathogenic to homeothermic vertebrates including humans have been associated with free-living migratory birds. migratory birds of diverse species can play sig ... | 2004 | 15650082 |
| production of a proteolytically active protein, chlamydial protease/proteasome-like activity factor, by five different chlamydia species. | we have previously identified a chlamydial protein, chlamydial protease/proteasome-like activity factor (cpaf), for degrading host transcription factors in cells infected with the human chlamydial species chlamydia trachomatis or chlamydia pneumoniae. we now report that functional cpaf was also produced during infection with the species chlamydia muridarum, chlamydia psittaci, and chlamydia caviae, which primarily infect nonhuman hosts. | 2005 | 15731091 |
| compendium of measures to control chlamydophila psittaci (formerly chlamydia psittaci) infection among humans (psittacosis) and pet birds, 2005. | psittacosis, also known as parrot fever and ornithosis, is a bacterial infection of humans that can cause severe pneumonia and other serious health problems. it is caused by chlamydophila psittaci, formerly known as chlamydia psittaci. from 1988 through 2003, 935 human cases of psittacosis were reported to the cdc and most resulted from exposure to infected pet birds, usually cockatiels, parakeets, parrots, and macaws. in birds, c. psittaci infection is referred to as avian chlamydiosis. infecte ... | 2005 | 15742693 |
| key role of chlamydophila psittaci on belgian turkey farms in association with other respiratory pathogens. | two hundred turkey sera from eight belgian and two french farms were tested for the presence of antibodies against avian pneumovirus (apv), ornithobacterium rhinotracheale (ort), mycoplasma gallisepticum, mycoplasma meleagridis and chlamydophila psittaci. at slaughter, c. psittaci, apv and ort antibodies were detected in 94, 34 and 6.5% of the turkeys, respectively. no antibodies against m. gallisepticum or m. meleagridis were present. additionally, turkeys on three belgian farms were examined f ... | 2005 | 15795081 |
| screening the whole genome of a pathogen in vivo for individual protective antigens. | we report the results of a general protocol that was used to screen the whole genome of chlamydophila abortus, type strain b577 (formerly chlamydia psittaci strain b577), in a mouse pneumonia model. genetic immunization was used to functionally test the genes of c. abortus as vaccines in a mouse challenge system. nine gene fragments were isolated that conferred protection, with five protecting as effectively as the live-vaccine positive control. bioinformatics approaches were unable to reconstru ... | 2005 | 15811648 |
| the latest from the ivd industry december 2004. chlamydia--pathogens that are still often underestimated. | chlamydiae are bacteria living as intracellular parasites. contemporary differentiation distinguishes nine species, of which three are relevant to human medicine. infections with chlamydia trachomatis are among the most widespread sexually transmitted diseases. chlamydophila pneumoniae invade the respiratory tract, chlamydophila psittaci is the pathogen of ornithosis. chlamydial infections frequently progress asymptomatically and hence remain untreated. serious chronic secondary diseases are the ... | 2005 | 15819175 |
