Globally, Border disease virus (BDV) has caused substantial economic losses among small ruminants (sheep and goats). This is the first molecular study carried out in Mosul city, Iraq. To determine the prevalence of Border Disease Virus and to examine problem of persistent infection (PI) using Reverse transcriptase polymerase chain reaction technique (RT-PCR) in female local breed of small ruminants. During the period between November 2018 to June 2019, 364 blood samples were collected from 264 local Awassi sheep and 100 local cross breed goats secure provided by private breeders. The animals were of ≥1.5 years old and the samples were obtained from various locations in Mosul city, with varying rearing methods and had not been vaccinated against BDV. This investigation indicated that the prevalence of BDV infection in sheep and goats were 15.9% (42/264) and 3% (3/100) respectively, whereas the occurrence of PI in sheep was 2.38% and in goats was 0%. Hence it was concluded that Border disease was circulating in small ruminants in Mosul city. This calls for a need to design programs to monitor and control the disease and eventually eradicate it is prevalence in Mosul city.

The objective of the current study is to examine the incidence of Lucilia sericata larvae in the sheep in Mosul city, Iraq. From a total of 670 sheep examined, 92 sheep of them 13.7% were infested with Lucilia sericata larvae. For the 516 larvae found in the sheep, 146 (28.3%) was detected to be of the first instars larva, 120 (23.3%) was second in stars larva and 250 (48.4) as third instars larva. As the average number of larvae in the infested animals was 5.6. The infestation percentage in males was higher 26.3% compared to the females 4.2%, where there is no significant difference reported concerning with the age. The prevalence of Lucilia sericata larvae was 8.4% in spring, 38.9 % in summer, 2.4% in autumn and 1.5% in winter. The difference in terms of seasons were statistically significant. Sheep in the rural areas had higher infestation rate in comparison to the sheep in urban area. Most lesions occurred in the breech region, flank, leg and inter digital space of a foot. The percentage of adult flies that merged was 73.3% and the pupariation period was 12 to 20 hours, while the incubation and moulting periods were 7 to 10 days. All flies were similar in the external appearance and belonging to Lucilia sericata causing strike disease in sheep.

“…The diseases resulting from an infection of a virus belonging to a beta retrovirus called Jaagsiekte sheep retrovirus (JSRV) [1]. OPA was first recorded in South Africa in the 19th century where it was called Jaagsiekte which is derived from the Afrikaans for (chasing sicknesses) and disease has been noticed in wide types of breeds of sheep and in different countries over the world [2][3][4][5]. The characteristic of tumor cells in OPA thought to be originated from type two of alveolar epithelial cells or Clara cells, which is recorded as secretary cells and lining the epithelium of alveoli of the lung therefore, the disease is characterized by excessive secretion fluids by the tumor cells and these fluids are accumulated in the lung, which be sources of infectious virus and causes important economic and animal welfare problems [6].…”

T HE current study aimed to investigate the prevalence and pathological observation of ovine pulmonary adenocarcinoma (OPA) in sheep and goats at Duhok abattoir of Iraq. A total of 4061 lung samples from small ruminants (3667 sheep and 394 goats) were selected randomly from slaughtered sheep and goats. All samples were examined macroscopically is involving color, consistency, texture, adhesion, pattern, the number of the lesion, distribution, the nature of exudates and lobe of the lung are involved. Histopathological examinations were performed from 55 affected lungs The results showed that the prevalence of disease in the Duhok abattoir was 1.35% based on macroscopical features while results found 45.45% percentages of affected lung with OPA according to histopathological features, the gross lesions of OPA in sheep and goatsfound that the upper respiratory part was filled with excessive frothy material fluid and the lungs were heavy, enlargement, and edematous appearance. While the important histopathological observations of the affected parts was varied from small discrete nodules that appears white in color and are involves both lungs, measuring around 0.5-2 cm of the diaphragmatic and other lobes were recorded, and classified as classical and atypical form. Histologically results showed the presence of multiple proliferations foci of neoplastic cells in the epithelial cell of alveoli and bronchi, these proliferations appear either papillary or as the impression of solid growths appearance or acinar shape. Inconclusion our study gives important data about the prevalence and pathological changes of OPA in sheep and goats at the Duhok abattoir of Iraq.
