Bluetongue is an infectious viral disease that is endemic in the domestic livestock populations of all tropical and subtropical countries. BT was first reported in Iran in 1972, however until now there is the absence of comprehensive information on the BT status in Iran. We aimed to present the seroprevalence on BT in farm animals of Iran based-on a meta-analysis study. The meta-analysis study was conducted in national and international databases to find articles which evaluated bluetongue seroprevalence by antibody-captured ELISA test in livestock in Iran by searching terms including bluetongue, sheep, ovine, goat, caprine, cow, cattle, bovine, buffalo, camel, Iran and prevalence alone or in combination in both English and Farsi language. After reviewing 82 published articles, a total of 48 studies from 29 articles were eligible to be included in this meta-analysis study. The total seroprevalence of bluetongue in apparently healthy sheep, goat, cow and camel at animal level based on ELISA test was 50.4% (95% CI= 43.5-57.2), 79.2% (95% CI= 70.7-85.8), 3.3% (95% CI= 0.6-15.0) and 44.8% (95% CI= 20.8-71.5), respectively. The estimated pooled odds ratios between abortion history and bluetongue infection estimated among sheep (OR=1.75, 95 % CI= 0.84 to 3.68) and goat (OR=2.93, 95 % CI= 1.26 to 6.80). A well-defined control strategy for preventing and controlling BTV spread in Iran should be based on further studies on BT epidemiology and BTV serotypes, vector control, animal movement restrictions and vaccination program to reduce.

About 180,000 old world camels (OWCs) including one-humped (Camelus Dromedarius) and two-humped (Camelus Bactrianus) camels (only 100-300 individuals) live in Iran. Abortion is one of the problems of camel breeders in Iran at various aspects, i.e. economical, animal healthcare or zoonotic. So far, some epizootological studies have been conducted on infectious diseases of Iranian camels. However, there is the absence of comprehensive information on the camel abortion status in Iran. We aimed at collecting all the available information on abortion in Dromedary and Bactrian camels in Iran to have a better picture of the situation in the country. Based on studies that examined the causes of abortion of dromedary camels in different provinces; Brucellosis, trypanosomiasis, leptospirosis, salmonellosis, bovine viral diarrhea, infectious bovine rhinotracheitis and aspergillosis are common factors of abortion in the country. This review can provide baseline information for future research and give significant contributions to figuring the disease control strategies.
