GmbH - Ornithose. Ornithose L'ornithose est une maladie infectieuse qui affecte beaucoup d'espèces d'oiseaux, à l'échelle planétaire. Elle peut être transmise aux humains et à d'autres mammifères. Agents pathogènes: Chlamydia psittaci. Les Chlamydias sont des micro-organismes immobiles qui envahissent, en parasite, les cellules.
L'infection apparaît par l'inhalation de la poussière en suspension, contenant les germes, par la consommation d'eau ou d'aliments contaminés par les fientes ou encore en nourissant les pigeonneaux par le lait et par le bec. Symptômes de la maladie: L'ornithose apparaît sous deux formes: - La forme aiguë peut être identifiée chez les jeunes pigeons à partir: des bruits d'halètement, de conjonctivites uni- ou bilatérales et d'entérites muco-aqueuses avec diarrhées. - La forme chronique est plus souvent rencontrée chez les oiseaux adultes qui, dans tous les cas, montrent peu ou pas de signes de maladie. Affections similaires: Coryza, Salmonellose, Infection à paramyxovirus. La chlamydiophilose.
Mis à jour le Jeudi, 17 Mai 2012 La chlamydophilose : une maladie des oiseaux d'origine bactérienne, de diagnostic difficile qui peut être grave pour l’oiseau et son entourage Qu’est-ce que la chlamydophilose ? La chlamydophilose est une maladie bactérienne des oiseaux dont l’agent responsable est Chlamydophila psittaci. A l’origine, cette maladie a été dénommée psittacose, car on pensait que seuls les Psittacidés transmettaient la maladie. Quelle est son épidémiologie ? Réceptivité Au moins 150 espèces d’oiseaux peuvent héberger l’agent responsable de cette maladie, et parmi celles-ci les Psittacidés (certaines espèces semblent néanmoins relativement résistantes, notamment les cacatoès), les Columbidés (pigeons, tourterelles, colombes), les Gallinacés (poules, dindes, pintades, dindons, faisans), les Passériformes (canaris, diamants de Gould, paddas, moineaux), mais aussi les mouettes, les pétrels, les rapaces, les autruches,…..Son incidence semble faible chez les canaris.
La radiographie. DETECTION OF CHLAMYDIA PSITTACI INFECTION IN PET BIRDS USING A MOLECULAR BASED DIAGNOSTIC ASSAY - by Dr. Robert Dahlhausen DVM,MS & Dr. C. Steven Radabaugh DVM, MS. SummaryChlamydia psittaci infection is well established in our pet bird population. Infections range from a clinically inapparent state, with intermittent shedding of the organism, to overt clinical disease and mortality.
Establishing a confirmatory diagnosis of infection in the live bird is difficult as no single test can accurately diagnose the disease in all species or at all times. Conventional diagnostic methods have inherent problems in detection (sensitivity & specificity) and interpretation of results which are often equivocal. A molecular based DNA assay was developed to test clinical samples for the presence of the chlamydial organism.
Test performance was evaluated both in vitro and in vivo via a controlled infectivity study. The molecular based assay was extremely sensitive and specific in detecting Chlamydia psittaci in infected birds. IntroductionAvian chlamydiosis is an important disease that has historically affected aviculture for decades. Materials and Methods TABLE 1. Chlamydia Psittaci. Chlamydia psittaci - also referred to as Psittacosis, Parrot Fever or chlamydiosis. The word Psittacosis comes from the Greek word Psittakos, meaning parrot. Chlamydia are gram negative, spherical, (0.4-0.6 micron diameter), intracellular parasites that people sometimes referred to as "energy parasites" because they use ATP (a crucial energy containing metabolite) produced by the host cell, hence, the term "energy parasites.
Incubation periods in caged birds vary from days to weeks and longer. Most commonly this period is approximately 3 to 10 days. Latent infections are common and active disease may occur several years after exposure. The incubation period of this disease is however difficult to assess due to these chronically infected birds that develop persistent, asymptomatic infections. In birds, C. psittaci may manifest itself as an upper respiratory infection with nasal, and or ocular discharge, diarrhea, or a combination of all three. Chlamydia Psittaci.
