| severe leukopenia and liver necrosis in young african grey parrots (psittacus erithacus erithacus) infected with psittacine circovirus. | this paper describes the signs, clinical pathology, and postmortem findings in 14 young african grey parrots (psittacus erithacus erithacus) that were naturally infected with psittacine beak and feather disease (pbfd) virus (psittacine circovirus). all but two of the parrots had severe leukopenia at clinical presentation. two other parrots also had severe anemia. all birds died within 3 wk after presentation. postmortem examination documented liver necrosis in 11 of 14 birds and secondary bacter ... | 2000 | 10879931 |
| chlamydophila psittaci genotype e/b transmission from african grey parrots to humans. | thirty-six birds from a parrot relief and breeding centre, as well as the manager, were examined for the presence of chlamydophila psittaci. in the relief unit, 5 of 20 african grey parrots showed depression, ruffled feathers, loss of weight and mild dyspnoea. the birds received no antibiotic treatment. birds of the breeding unit, 14 blue and gold macaws and 2 green-winged macaws, were healthy. they received doxycycline at the start of each breeding season. the manager complained of shortness of ... | 2007 | 17644718 |
| mixed infection with reovirus and chlamydophila in a flock of budgerigars (melopsittacus undulatus). | eleven budgerigars (melopsittacus undulatus) from a zoological collection presented at necropsy with emaciation and splenomegaly or hepatomegaly or both. polymerase chain reaction assays performed on liver and spleen samples were positive for chlamydophila psittaci in 2 of 3 birds tested, and histologic findings in 2 additional birds were compatible with chlamydiosis. the aviary was subsequently closed to the public, and a 45-day treatment regimen with doxycycline in the seeds was initiated. no ... | 2010 | 21302762 |
| pcr-based diagnosis, molecular characterization and detection of atypical strains of avian chlamydia psittaci in companion and wild birds. | chlamydiosis is one of the most important infectious diseases of birds. in this study, 253 clinical samples were taken from 27 bird species belonging to seven orders. thirty-two (12.6%) samples were positive for chlamydia psittaci major outer membrane gene (ompa) dna by a nested polymerase chain reaction (pcr). twelve nested pcr-positive specimens were typed by ompa gene-based pcr-restricted fragment length polymorphism, using ctu/ctl primers and alui restriction enzyme. four restriction pattern ... | 2013 | 23391180 |
| molecular identification and successful treatment of chlamydophila psittaci (genotype b) in a clinically affected congo african grey parrot (psittacus erithacus erithacus). | avian chlamydiosis is caused by chlamydiophila psittaci with the highest infection rate in parrots (psittacidae) and pigeons (columbiformes). a two-year-old congo african grey parrot was examined since the bird had shown clinical signs of anorexia, depression, diarrhea, and mild dyspnea and based on biochemical and hemathological analysis the bird was diagnosed as having anemia, leukocytosis, heterophilia, lymphopenia and monocytosis. with regards to clinical and paraclinical findings, the case ... | 2016 | 28224015 |
