The College of Agriculture at the University of Basra holds a scientific symposium entitled Fish Viruses and the Dangers of their Transmission to Humans The College of Agriculture at the University of Basra holds a symposium through the live broadcast entitled Fish Viruses and the Dangers of their Transmission to Humans, which was held using the Cisco platform. 250 visitors attended, and the symposium included three lectures. Prof. Khalida Salem Khudair, a teacher in the fish department, her lecture entitled Viral Fish Diseases, in which she showed that the virus enters the body of fish through the skin, gillers, and gastrointestinal tract, while the eyes and the genital canal are to a lesser extent compared to other methods. I also mentioned some diseases caused by viruses, which include RNA that infects fish, including Spring carp disease, Spring viraemia of carp, and Rhabdovirus. The diseases that cause DNA viruses are Pox disease and Fish cauliflower disease in fish. As for the second lecture, it was given by Prof. Hussein Abdul Saud Al-Tadrisi, Department of Fish, on cell fusion as a link between viruses and cancer, in which he indicated that in cells and in the presence of viral proteins that merge with biological membranes, this condition causes what is called cell fusion and thus the production of hybrid cells in the body of the organism. He also distinguished between this abnormal fusion and the normal physiological fusion that takes place for the purpose of cell differentiation. The third lecture was addressed by Prof. Abdul Amir Rahim Jassim is the most important feature of viruses and their ability to mutate or mutation, which is considered one of the effective reasons for its transmission to humans. It deals with the most important types of viruses that are transmitted from animals to the human body, such as Ebola and SARS.
