A three-year-old ewe was received as a terminal stage animal for necropsy in the Teaching Veterinary Hospital, College of Veterinary Medicine, the University of Mosul, on 18/12/2018. The animal was carried alive from the Al-Fthilya region in the eastern north of Mosul and expired before hospitalization. Statement of the owner prevailed sudden deaths of healthy animals or a concise course of illness followed by respiratory distress and nervous manifestations and death at 14 mature animals within mortality rate reached 15.5% in the herd. Necropsy findings and histopathological analysis showed that encephalitis included hyperemic cortical blood vessels, severe perineuronal edema, microglial proliferation. The lungs revealed severe pulmonary edema and signs of peracute pneumonia. Liver sections demonstrated congested portal and central veins and lobular sinusoids with centrilobular coagulative degeneration. At the kidneys, we detected both glomerular and interstitial nephritis with severe tubular cell necrosis. We concluded a state of bacterial septic shock, suggesting Pasteurellosis as a probable etiologic factor from the symptoms and pathological examination. The case was reported, and laboratory tests were requested.

Schmallenberg virus is an emergent disease which infect cattle, sheep and goats which cause loss of condition, diarrhea, and abortion in pregnant animals, so this study was conducted to detect the antibodies in imported calves by using cELISA, so 400 blood samples was collected calves in different ages and healthy status in a period between October 2018 to September 2019 in Nineveh province, the investigation of specific antibodies was done by competitive Enzyme Linked Immuno Sorbent Assay, the results showed that the prevalence of Schmallenberg virus in imported calves was 21% (84 positive from 400 samples), high prevalence of infection in the animals more than 6 months to 1 year old 11.5% when compare with animals less than 6 months of age 9.5%, high incidence of infection in animals suffer from various clinical signs 17% and the healthy apparent animals recorded low prevalence of infection 4%, samples which collected in spring months recorded high prevalence of infection 7.5% while the lowest prevalence of infection with the virus recorded in winter months 2%, with significant variance in spring and summer months compared with other seasons, in conclusion this study was conducted that schmallenberg virus is newly emerge in Iraq and this study is firstly recorded this virus in cattle in Iraq.

The purpose of this study is first trial to detect of pigeon circovirus, so 1sr group include 100 cloacal swabs were collected 55 healthy and 45 ill pigeons, 36 yearlings and 64 adults, the 2nd group included organs was liver, spleen, bursa of Fabricius from 41 young pigeons 10-30 days old and bursa of Fabricius, liver, spleen from 28 dead in shell pigeon embryo in the 3rd group. DNA extracted from this samples and detection of virus DNA was attempt using polymerase chain reaction, after DNA amplification, the final products of the amplicon with 331 bp was cleared by using electrophoresis using agarose gel at concentration 2%. Results of viral DNA amplification were positive, which revealed as band in 331 bp the results showed that ill yearling pigeons recording high infectivity rate 66.7% compare with healthy yearling pigeons and adult once, the bursa of Fabricius samples of dead yearling pigeons recorded high prevalence 36.58% when compare with liver and spleen samples, DNA of pigeon circovirus high detected 60.71% in bursa of Fabricius of dead in shell pigeon conclusion pigeon circovirus affected the racing pigeon in Mosul, Iraq.

Through this study 122 individual fecal samples were collected from dogs, with different ages, sexes, and breeding management (stray and pet house hold). Some dogs were with healthy appearances while others were suffered from diarrhea, anorexia, depression, dehydration. Infection was investigated by light microscope after flotation technique by using Sheather's sugar solution. if the sample gives positive to oocyst (H. heydorni or other relative group), were mixed with potassium dichromate solution a rate of 2.5% for the stimulation of sporulation. DNA extraction was done using 2% sarcosyl, pronase E followed by phenol/chloroform extraction then precipitation attempt using ethanol. DNA amplification was attempt using H. heydorni primers JS4 and JS5 n microscope examination give 78 sample positives to the presence of oocyst, while polymerase chain reaction showed total percentage of infection with H. heydorni was 34.6% (27 case give positive reaction to PCR). Dogs less than 6 months of age show high infective rate 17.9%, dogs which suffer from gastrointestinal tract troubles (diarrhea, anorexia and dehydration) gave high infective rate 24.4%. Stray dogs gave high prevalence of infection to H. heydorni 25.6% when compared with pet house hold dogs which recorded 9% percentage of infection. This study is the first recorded H. heydorni in dogs in Mosul city.
