Abstract
Egyptian fish farms have faced unexplained mortality of tilapia during the summer months in recent years. Epidemiological surveys indicated that 37% of fish farms were affected in 2015 with an average mortality rate of 9.2% and a potential economic impact of around US$ 100 million. Despite a number of researchers and organizations investigating potential causes results so far have been inconclusive. Meanwhile recent reports emerged of the presence of a new orthomyxovirus, Tilapia Lake Virus (TiLV) in Israel, which shares a border and migrating avifauna with Egypt. Tissue samples from seven farms affected by ‘summer mortality’ were tested at the ÍæÅ¼½ã½ã for TiLV. Samples from three of seven farms tested positive using PCR; the first time that TiLV has been identified in Egypt. Sequence analysis yielded a TiLV sequence with 93% homology to the published TiLV sequence described from Israel. More research is required to determine if TiLV is linked to ‘summer mortality’.
