Avian Malaria Deaths in Parrots, Europe

چکیده
feline strains from Italy and Australia grouped together, as did the P[9] strains from the United States. Thus, both the VP7 and VP4 genes of G3P[9] strain identifi ed in this study were most closely related to a racoon dog rotavirus strain (RACDG5), suggesting an animal origin of this rotavirus strain. These strains are likely an example of an animal strain causing limited disease in humans, rather than existence of a true strain, which has entered and adapted to the human environment. Recent wholegenome sequencing of 2 G3P[9] strains isolated from children in Italy showed they were composed of genes of human, bovine, and feline origin (2); whether the G3P[9] strains from Malaysia identifi ed in this study are also human/animal reassortant strains requires further study. Identifi cation of G3P[9] strains in Malaysia continues to highlight the presence of these rare strains in Asian communities. The close similarity of the strains to a G3P[9] strain from a raccoon dog further highlights the transmission of rotavirus strains between animal and human sources. Whether this strain can establish itself in humans and cause disease is unknown, but the identifi cation of rare strains illustrates that movement of rotaviruses between various hosts does occur from time to time.

be a potential hazard for invading species. Avian malaria should therefore be considered a threat for exotic parrots in Europe until results of further epidemiologic and experimental studies are available. Because many European bird species have been introduced to the native range of the psittacines studied here, a concern has been expressed that these parasites already have become established ...
متن کاملAvian bornavirus associated with fatal disease in psittacine birds.
Thanks to new technologies which enable rapid and unbiased screening for viral nucleic acids in clinical specimens, an impressive number of previously unknown viruses have recently been discovered. Two research groups independently identified a novel negative-strand RNA virus, now designated avian bornavirus (ABV), in parrots with proventricular dilatation disease (PDD), a severe lymphoplasmacy...

Methods The secondary data on infant mortality was obtained on countries in Eastern Africa, Western Europe and Southern Asian countries between 1950 and 2010 expressed as deaths per 1,000 births. Countries in Western Europe were used for comparison purposes. The data also included inpatients (admissions and deaths in 2007) of water-related diseases such as malaria and diarrhoea, in Eastern Afri...
متن کاملA time series of infectious-like events in Australia between 2000 and 2013 leading to extended periods of increased deaths (all-cause mortality) with possible links to increased hospital medical admissions
Background and aims: Trends in deaths and medical admissions in the UK and Europe show evidence for a series of infectious-like events. These events have been overlooked by traditional surveillance methodologies. Preliminary evidence points to a rise in medical admissions in Australia around the same time as those observed in Europe, and this study was aimed to evaluate whether the deaths are o...
متن کاملAvian malaria: a new lease of life for an old experimental model to study the evolutionary ecology of Plasmodium.
Avian malaria has historically played an important role as a model in the study of human malaria, being a stimulus for the development of medical parasitology. Avian malaria has recently come back to the research scene as a unique animal model to understand the ecology and evolution of the disease, both in the field and in the laboratory. Avian malaria is highly prevalent in birds and mosquitoe...
