Phylogenetic analysis of Newcastle disease virus detected in Eritrea between 2017 and 2021.
Thirty-five samples collected from chickens in 13 commercial farms in Eritrea between 2017 and 2021 following reports of disease were screened for Newcastle disease virus. Seventeen samples (50%) were shown to be positive by RT-PCR. An initial analysis of partial fusion (F) gene sequences of 10 representative samples indicated that the viruses belonged to subgenotype VII.1.1. Subsequently, full F gene sequence analysis of four of these representative samples confirmed the genotype of the viruses but also revealed that they were not identical to each other suggesting different origins of the VII.1.1 subgenotype viruses circulating in Eritrea. These data have implications for the control of Newcastle disease within the poultry population in Eritrea.
期刊介绍:
Avian Pathology is the official journal of the World Veterinary Poultry Association and, since its first publication in 1972, has been a leading international journal for poultry disease scientists. It publishes material relevant to the entire field of infectious and non-infectious diseases of poultry and other birds. Accepted manuscripts will contribute novel data of interest to an international readership and will add significantly to knowledge and understanding of diseases, old or new. Subject areas include pathology, diagnosis, detection and characterisation of pathogens, infections of possible zoonotic importance, epidemiology, innate and immune responses, vaccines, gene sequences, genetics in relation to disease and physiological and biochemical changes in response to disease. First and subsequent reports of well-recognized diseases within a country are not acceptable unless they also include substantial new information about the disease or pathogen. Manuscripts on wild or pet birds should describe disease or pathogens in a significant number of birds, recognizing/suggesting serious potential impact on that species or that the disease or pathogen is of demonstrable relevance to poultry. Manuscripts on food-borne microorganisms acquired during or after processing, and those that catalogue the occurrence or properties of microorganisms, are unlikely to be considered for publication in the absence of data linking them to avian disease.
