An Unusual Encounter: Mycobacterium Paratuberculosis Infection in Wild Sheep.

Background: Johne's disease (JD), paratuberculosis, is a chronic and debilitating intestinal disease affecting ruminants, caused by Mycobacterium avium subspecies paratuberculosis (MAP). Although JD has been extensively studied in domestic livestock, its prevalence and impact on wildlife in Iran, particularly among wild sheep, remain underexplored.

Case Description: This study presents the first documented cases of JD in two free-ranging, 3-year-old Isfahan wild sheep (Ovis orientalis isphahanica), which exhibited weight loss, hyperthermia and neurological symptoms, including paddling movements.

Cerebral Hydatidosis in a Lamb.

A 6-month-old Afshari male lamb was examined on a semi-intensive farm due to anorexia and neurologic signs, including head tilt, circling, bilateral positive menace response and stupor. The sheep was slaughtered and necropsied. After routine parasitology and histopathology procedures, the occurrence of cerebral hydatidosis was confirmed.

Right parasternal echocardiographic reference values in the healthy male Iranian Shall sheep.

Background: Among the large animals, the heart of sheep is functionally and structurally very similar to the human heart. In research, sheep are used as an animal model to study the process of cardiac disease pathogenesis and treatment. Therefore, determining the normal values of the heart structures of sheep with echocardiography is of particular emphasis.

A rare case of Cysticercus tenuicollis infection in a neonate lamb: Evidence of prenatal transmission.

Cysticercosis develops in lambs following a Cysticercus tenuicollis infestation, which is the larval stage of Taenia hydatigena. A 7-day-old lamb was examined for depression, anorexia, fever (40.5°C), congested mucus membranes, reluctance to move, and a hunched back.

Prevention of LPS-induced acute respiratory distress syndrome in sheep by bone marrow-derived mesenchymal stem/stromal cells.

Materials And Methods: In this study, 10 male Shall sheep were used in two groups and bone marrow samples were collected and BM-MSCs isolated. Then experimental model of ARDS was induced by intrapulmonary injection of LPS to dose of 400 μg/kg. Twenty-four hours after LPS injection, 5 × 10 cells of BM-MSCs were autologous transferred in the group of treatment and 1 ml PBS was infused in the group of control as intrapulmonary.

A report on infection in a wild goat .

is the larval stage of inhabiting the small intestine of dogs and wild carnivores as the definitive hosts. A two-year-old wild female goat () was referred with signs of lateral recumbency and seizure for four days and loss of appetite. In clinical examination, paddling, convulsion, and unconsciousness were observed indicating central nervous system disorder.

L.: the anti-immature leech () activity compared to Niclosomide.

This study was carried out to determine the effects of methanolic extracts of L. on compared with Niclosomide. In this experimental study in September 2010, a number of leeches (70 in total) from the southern area of Ilam province were prepared, and the effects of methanolic extract of L.
