All animals were vaccinated against FMD with the locally produced bivalent vaccine containing O1 and A/Egy/2006 strains two months before the onset of the outbreak. Laboratory examination of the samples collected from diseased and dead animals’ revealed detection of a newly emerged serotype of FMD (SAT2). Although, all buffaloes (8/8) in the herd were infected (100%), none of them died, while lactating Holstein cattle showed varying morbidity rates along the period of the outbreak with peak rates in March followed by April, May and June. Crud mortality and case fatality rates among cattle peaked during April 2012 to reach 9.3 and 21.7%, respectively. Calves were the most affected animals with the highest morbidities and mortalities. The high prevalence of the disease among all animal categories in the investigated farm is attributed to the lack of previous immunity through vaccination against the new serotype of the virus. In addition, the hygienic and biosecurity measures in the farm were unsatisfactory with respect to prevention of introduction and spread of the disease between the farm units. The prevalent weather conditions during the outbreak might have played a role in spread of the FMDv, especially ambient temperature, humidity and wind movement.  a0005-9366
