“…Une étude récente sur 41 oiseaux (amazones, conures, perroquets, aras...) en captivité, au Brésil, a montré la présence d'un même PsHV chez tous les animaux testés. Par ailleurs, sur 29 oiseaux autopsiés, 19 ont présenté des lésions (néphrite, splé-nomégalie, hépatomégalie et hépatite suggérant une herpèsvi-rose mais seuls deux oiseaux présentaient des inclusions intranucléaires) (Luppi et al 2011). Le virus de la maladie de Pacheco est donc très répandu dans certaines espèces de psittacidés en captivité qui apparaissent le plus souvent en bonne santé et peuvent le disséminer dans l'environnement.…”

Dans l'ordre des Herpesvirales et la famille des Herpesviridae, les herpèsvirus des oiseaux, regroupés dans la sous-famille des Alphaherpesvirinae, infectent de nombreuses espèces aviaires (poulets, dindes, canards, pigeons, les perroquets, aigles, cigognes, faucons, grues, colins, cormorans, pingouins, hiboux…). Les principales herpèsviroses aviaires sont la maladie de Marek oncogène (Gallid herpesvirus 2, genre Mardivirus), la laryngotrachéite infectieuse (Gallid herpesvirus 1, genre Iltovirus), l'entérite à virus ou peste du canard (Anatid Herpesvirus, non classé, mais proche des genres In the order of Herpesvirales and the family of Herpesviridae, herpeviruses of birds, grouped in the subfamily of Alphaherpesvirinae, infect many avians,

“…Due to latent properties of Herpesviridae they may also remain a subclinical infection that influences the immune status of birds [1,2]. Herpesviruses of free-ranging birds fall into seven different species including herpesviruses of pigeons, falcons, vultures, owls and Psittacid herpesvirus (PsHV-1) affecting parrots [2-6]. CoHV-1 isolated from pigeons and falcons, presents similar antigenic features thus its differentiation by serological assays is not possible [7,8].…”

Phylogenetic analysis of Columbid herpesvirus-1 in rock pigeons, birds of prey and non-raptorial birds in Poland

BackgroundThe identity of herpesviruses isolated in Europe from domestic pigeons (Columbid herpesvirus-1 - CoHV-1) as well as falcons and owls remains unknown. All these herpesviruses are antigenically and genetically related. The falcons and owls are thought to have become infected during the ingestion of pigeon meat thus suggesting the virus’s capacity to infect a wide range of hosts. The aim of the conducted study was to detect the occurrence of CoHV-1 and estimating the similarities and differences in the DNA-dependent DNA polymerase gene of herpesviruses isolated from domestic pigeons, birds of prey and non-raptorial free-ranging birds in Poland.ResultsThe study has shown the presence of CoHV-1 in 20.4% (18/88) in the examined birds. In case of one CoHV-1, infected Peregrine Falcon (Falco peregrinus), neurological signs were observed. Nucleotide sequencing of the DNA-dependent DNA polymerase gene, showed a high similarity among Polish strains (100%), independently from the species of the affected birds. Only one compared CoHV-1 strain - KP 21/23 originating from Germany showed a slightly lower similarity at a level of 99.1%. Further analysis has shown the identity of DNA-dependent DNA polymerase of CoHV-1 strains and other herpesviruses present in poultry as well as other birds ranged from 35.4 to 44.9%. Interestingly CoHV-1 infection was also confirmed for the first time in four non-raptorial birds.ConclusionsThe current study has shown a high similarity of CoHV-1 strains and the possible transmission of herpesviruses between domestic rock pigeons and free-ranging birds including raptors and non-raptorial birds. Further studies focused on cloning and the analysis of the whole CoHV-1 genome which is needed to explain the role of the observed similarities and differences between field strains of columbid herpesviruses.

“…The DNA fragment sequenced is the 419 bp fragment corresponding to the UL16 ORF that showed 99–100% identity to the sequences of PsHV-1 present in GenBank. 14 Moreover, although the UL16 gene is located in a conserved region within the genome, when the sequences were compared with those of PsHV-2, PsHV-3, and PsHV-4 obtained from GenBank the similarity did not exceed 97%. Therefore, we suggest that all patterns discovered in this study belonged to genotype 1 (PsHV-1) and, probably, to serotype 1.…”

Thirty-six isolates of psittacid herpesvirus (PsHV), obtained from 12 different species of psittacids in Brazil, were genotypically characterized by restriction fragment length polymorphism (RFLP) analysis and PCR amplification. RFLP analysis with the PstI enzyme revealed four distinct restriction patterns (A1, X, W and Y), of which only A1 (corresponding to PsHV-1) had previously been described. To study PCR amplification patterns, six pairs of primers were used. Using this method, six variants were identified, of which, variants 10, 8, and 9 (in this order) were most prevalent, followed by variants 1, 4, and 5. It was not possible to correlate the PCR and RFLP patterns. Twenty-nine of the 36 isolates were shown to contain a 419 bp fragment of the UL16 gene, displaying high similarity to the PsHV-1 sequences available in GenBank. Comparison of the results with the literature data suggests that the 36 Brazilian isolates from this study belong to genotype 1 and serotype 1.
