“…This could suggest the vertical transmission of the parasite and its involvement in small ruminants and equines abortion. Consistently, neosporosis was previously reported in range of 17.4% to 28.6% in aborted and healthy bovines according to the diagnostic approaches with ELISA and PCR assays in Iraq (AL-Badrani 2012, Nooruldeen et al 2021. In Wasit province (Iraq) it was showed that the prevalence rate of N. caninum was 13.7% in aborted ovine foetuses (Al-Shaeli et al 2020) and 18.9% in aborted caprine foetuses (Faraj and Ghattof 2018).…”

Neospora caninum (N. caninum) is the etiologic agent of neosporosis, a potential cause of severe reproductive disorders in cattle, small ruminants, equines, wild animals and canids across the world. The current study is performed to estimate molecular prevalence of N. caninum in small ruminants and equines that had abortion in Kurdistan region of Iraq. A total of 64 tissue samples (brain, placenta, heart, lung and liver) were taken from aborted foetuses, with a total of 122 dam blood samples taken from 63 sheep, 39 goats, 12 mares and 8 jennies in local breed fields. Besides, a risk factor analysis for N. caninum positive animals was performed. The observed prevalence of N. caninum DNA in the blood of sheep, goats, horses and donkeys were 20.6%, 17.9%, 21.4% and 25.0%, respectively, and 19.3%, 17.6%, 18.1 and 20.0% in the aborted foetuses of the animals, respectively. Moreover, occurrence of N. caninum was 20.3% in the blood of aborted dams, while it was 18.7% in their aborted foetuses. Confirmatory analysis was also done through constructing a phylogenetic tree to compare the partial sequences of the Nc-5 gene in our isolates (OP771519, OP771520, OP771521 and OP771522) with the GenBank sequences. This showed 98-100% sequence identity with other N. caninum strains in the GenBank database. Older small ruminants and equines had a higher risk of being positive for N. caninum and exposure to dogs were considered as significant risk factors for N. caninum infection in the studied animals (p<0.05). Thus, the results of this study suggest that N. caninum is one of the microbial abortive agents in small ruminants and equines in Kurdistan region of Iraq. It is hoped that the results of this study will help to control animal abortion in livestock and reduce the economic losses.

Although ongoing control strategies are attempting to minimize certain metabolic disorders such as hyperketonemia, factors such as genetics, management, environment, and geography still present a potential challenge to the achievement of the desired results. In light of this, this study was conducted (i) to determine the prevalence of subclinical and clinical ketosis based on the concentration of ketone bodies (BHB) using ELISA Kit, and (ii) to examine a number of epidemiological risk factors related to the conditions. From October, 2020 to the January, 2021. A 80 blood samples were collected in a crosssectional survey in different areas of Mosul. Data included age, management systems, parity, and origin. At the cut-off point ≥1.2-≤ 1.4 mmol / L, the prevalence of subclinical ketosis was 27.5% and for clinical ketosis it was 5%. Results revealed that the animals aged > 3 years were more at risk for subclinical ketosis compared to animals aged ≤ 3 years RR = 2.6471. Multiparous animals were more at risk compared to the primiparous (two or less births) RR = 2.0652. No significant difference between the animals' origins RR = 0.6863. Indoor and outdoor system animals were more at risk for subclinical ketosis compared to the indoor system only RR = 2.1389. In conclusion, hyperketonemia is prevalent in Mosul. Certain risk factors should be taking into account when planning control programs. Attention should be paid to diagnosis, management, and control of this disease during the risk stage to avert economic loss to the dairy farmers.

Bovine hypodermosis has been known as a veterinary disease that mainly caused by Hypoderma bovis and Hypoderma lineatum. This study aimed to determine seroprevalence of cattle grubs in Mosul, Iraq utilizing indirect ELISA as well as effect of some risk factors on prevalence of hypodermosis. A total of two hundred blood specimens were collected from healthy and infested cattle through direct palpation. All samples were collected from cattle at Teaching Veterinary Hospital, Mosul abattoir, Kokjali and Bazwaya region during October 2020 to March 2021. Outcomes of iELISA showed 40.5% as an infestation rate of hypodermosis. Notably, infestation intensity has distributed as light, moderate and sever 11, 18.5 and 70.3% respectively. Interestingly, highest seroprevalence of hypodermosis was recorded in October 67.7%, and the lowest was recorded in February and March 22.2%, 25% respectively. Observations of current study also recorded the infection rate in age was 54.7% in animals less than 3 years old, and the lowest was 16% in animals more than 3 years old. Moreover, breed showed a significant risk factor 53.8% for imported cattle and 14.7% for local breed. Importantly, risk factor concerning area recorded the highest rate in Kokjali 52.2%. In contrast, the lowest rate recorded in Teaching Veterinary Hospital 14.8%. The present study is the first investigation to identify cattle hypodermosis by iELISA in Mosul, Iraq. iELISA has been approved as the best diagnostic tool for early detection of hypodermosis during the migrating phase. Interestingly, age, breed and months of study were significant risk factors.
