Cetacean Morbillivirus

The transmission of the morbillivirus to a host requires very close contact between the two species. When the cetacean morbillivirus infects the host cell, it stays in the infected host for only a short time after infection (Ohishi 186). Once a host cell gets infected with the cetacean morbillivirus, the virus can be spread from animal to animal by contact with infected animals through entry of the eyes, stomach, and mouth, wounds in the skin, or reproductive tract. The cetacean morbillivirus can also be transmitted from an infected animal to a healthy host by inhaling particles (Morbillivirus 1). Assembly and replication of the cetacean morbillivirus both occur in the cytoplasm. Along with this, characteristics of the morbillivirus show that
Ribonucleocapsid are then released in the cytoplasm once the fusion of the membrane has occurred (Bressem 3). Both the H glycoprotein and the F glycoprotein can be used to interact with cellular receptors that are used to allow the entry of the virus, along with determining the susceptibility of the host, tissue tropism, and viral pathogenesis (Bressem 3). Replication of the virus occurs after there are enough nucleoproteins present in the cell to encapsulate “neosynthetized antigenomes and genomes” (Maruyama 2-3). The replication type that occurs within a cetacean morbillivirus and its host cell follows the negative-stranded RNA virus replication model. A virion (virus particle) is then released through the intereaction between the ribonucleocapsid and the matrix protein under the plasma membrane (Bressem 3). The replicated virus is then released from the cell using the budding method (Maruyama 2). These cycle continues as the spread of the virus increases and continues. Once the cetacean morbillivirus leaves the host cell, it does not survive very long in natural environments, meaning that the life of the virus after infection has already occurred is
