Sequences and Phylogenetic Analysis of Envelope (E) Gene of Iranian Infectious Bronchitis Virus Isolates in Iran
Background and Aims: Infectious bronchitis virus (IBV) is the etiological agent of infectious bronchitis (IB), which is an acute and highly contagious disease of the respiratory and sometimes the urogenital tracts of chickens. In Iran, the disease has been identified in chicken flocks with serological and virus isolation methods. Gene 3c (E) encode envelop (small membrane) protein. For envelope...
متن کاملGenomic organization of infectious salmon anaemia virus.
The RNA genome segment order, nucleotide sequence and the putative encoded proteins were determined for infectious salmon anaemia virus (ISAV). Eight segments of genomic viral RNA between 1.0 and 2.4 kb in length were identified. RNA segments 1-6 each had a predicted single open reading frame encoding the P1, PB1, NP, P2, P3 and HA proteins, respectively. Segment 7 encoded the P4/P5 proteins an...
متن کاملRelative resistance of Pacific salmon to infectious salmon anaemia virus.
Infectious salmon anaemia (ISA) is a major disease of Atlantic salmon, Salmo salar, caused by an orthomyxovirus (ISAV). Increases in global aquaculture and the international movement of fish made it important to determine if Pacific salmon are at risk. Steelhead trout, Oncorhynchus mykiss, and chum, O. keta, Chinook, O. tshawytscha, coho, O. kisutch, and Atlantic salmon were injected intraperit...
متن کاملModelling the spread of infectious salmon anaemia among salmon farms based on seaway distances between farms and genetic relationships between infectious salmon anaemia virus isolates.
Infectious salmon anaemia (ISA) is an important infectious disease in Atlantic salmon farming causing recurrent epidemic outbreaks worldwide. The focus of this paper is on tracing the spread of ISA among Norwegian salmon farms. To trace transmission pathways for the ISA virus (ISAV), we use phylogenetic relationships between virus isolates in combination with space-time data on disease occurren...
متن کاملInfectious salmon anaemia virus (ISAV) mucosal infection in Atlantic salmon
All viruses infecting fish must cross the surface mucosal barrier to successfully enter a host. Infectious salmon anaemia virus (ISAV), the causative agent of the economically important infectious salmon anaemia (ISA) in Atlantic salmon, Salmo salar L., has been shown to use the gills as its entry point. However, other entry ports have not been investigated despite the expression of virus recep...
