Just One Knot<\/h3>\n
Co-author Professor Francois Balloux from the Institute of Genetics at the University of California, Los Angeles, stated: “We must consider humans as just one knot in a vast network of hosts exchanging disease-causing agents ad infinitum.”<\/p>\n
Results also show that viral host jumps, on average, are associated with an increase in genetic changes, or mutations, in viruses compared to their continuous evolution alongside a single host animal, reflecting how viruses adapt to exploit their new hosts better.<\/p>\n
Furthermore, viruses already infecting various animal species show weaker signs of this adaptive process, indicating that broad-host-range viruses may inherently possess traits making them more capable of infecting a diverse range of hosts.<\/p>\n
If a virus carried by humans infects a new animal species, the virus may continue to thrive even if eradicated among humans, or it may develop new adaptations before re-infecting humans.<\/p>\n
Cell Entry<\/h3>\n
Cell entry is generally seen as the first step in virus infection of the host. However, the team found many modifications associated with host jumps were not found in viral proteins enabling them to bind to and enter host cells. This suggests that viral host adaptation is a complex process that still needs to be fully understood.<\/p>\n
Co-author Dr. Lucy van Dorp from the Institute of Genetics at the University of California, Los Angeles, said: “Our research would not have been possible without countless research teams openly sharing their data through public databases.”<\/p>\n
She added, “The main challenge moving forward is integrating knowledge and tools from diverse disciplines including genomics, epidemiology, and ecology to enhance our understanding of host jumps.”<\/p>\n","protected":false},"excerpt":{"rendered":"
