Sheep and goats represent an essential source of meat, milk and wool production. Infectious viral diseases of small ruminants hinder the expected benefits from these animals. The aim of the present review was to shed light on diagnostic procedures and monitoring of some important infectious viral diseases that affect small ruminants. Border disease (BDV) is caused by Pestiviruses. The affected herds are usually expressed high rates of infertility and production of underweighted-lambs. Affected lambs usually die within days after lambing. A commercial killed whole virus vaccine was produced for BDV. Louping ill (LI) is caused by the Louping ill virus, which is transmitted by Ixods ricinus ticks. The LI virus typically causes fever, anorexia and encephalomyelitis. Death could occur 1-3 days after the beginning of signs. The available Louping ill vaccine is composed of inactivated killed virus. Nairobi sheep disease (NSD) is a tick-born infectious disease caused by Rhipicephalus appendiculatus ticks, characterized clinically by fever, abortion hemorrhagic gastroenteritis and high mortality. Inactivated killed oil adjuvant virus vaccines are available for the control of Nairobi sheep disease. Akabane disease (AKAV) is a Culicoides borne viral disease belongs to orthobunyavirus that has a teratogenic effect on the fetus of cattle and small ruminants. A live attenuated virus vaccine and inactivated virus are commonly used. This review concluded that the modern diagnostic tools are urgently needed not only for diagnosis but also for monitoring viral disease control and control programs.

Because there was no such study done on identification of tick species by PCR technique in in Duhok Governorate, therefore present study was done to identify tick species by using molecular study by using of 16S rRNA and DNA sequencing. About 1000 ticks were collected from both sheep and goat, form Duhok Governorate including: Barwaria, Zakho, Sumeil, Mangeshik, Sersing, Shekhan and Akre, between May and June 2016, between April and June 2017. The result found during this study were six species under two genera of the hard ticks were identified by molecular study and sequencing including: three species were under the genus Hyalomma and three species were under the genus Rhipiciphalus that infect small ruminants in Duhok governorate from these species a new species under the Hylomma genra (Hyalomma asiatium asiaticum) with accession number (MN594484), was first time reported in Duhok governorate. Also phylogenetic tree was constructed depend on the 16S rRNA.

The current study aimed to investigate the possibility of using ultrasonography through abdominal probe in recording percentages of pregnancy, twins and genital pathological condition which affect the uterus for cases admitted to veterinary hospital in Kirkuk province as well as regulated visits to breeding projects of small ruminant and college of agriculture and forestry / Kirkuk university for the period from 01/10/2015 to 01/04/2016, which included 281 of ewes and does. The result of current study showed that that ratio of pregnancy was 75.9% in ewes and in does 47.6% while in case of twins in ewes 19.0% and in does 38.1%., while the genital pathological cases like endometritis and mucometritis (after birth) ratio in ewes 2.5% and in does 9.5%, in cases of pyometra in ewes 1.3% and in does 0.0%, while cases of embryonic deaths ratio in ewes 1.3% and in does 4.8%. It was concluded from the current study that; the possibility of diagnosis the genital pathological cases which affect the uterus as well as the identification of the single and twin pregnancy with investigation of the viability of embryos in both ewes and does by using ultrasonography with abdominal probe.
