Department of Animal and Poultry Health and Nutrition, Faculty of Veterinary Medicine, University of Tehran, Tehran, Iran.

Enzootic ovine abortion is caused by Chlamydia abortus and may result in abortion among small ruminants during the last 2-3 weeks of pregnancy. Enzootic abortion is diagnosed by isolation of the agent or detection of its nucleic acid in the products of abortion or vaginal excretions of freshly aborted females. Isolation of chlamydial agents in cell culture is the gold standard, so in the present study this method was employed. Read More

Department of Clinical Sciences, Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz, Ahvaz, Iran.

Mycoplasmas are important avian pathogens, which can cause both respiratory disease and synovitis in poultry that result in considerable economic losses to the poultry industry all over the world. The aim of this study was to determine the prevalence of Mycoplasma gallisepticum and Mycoplasma synoviae infections among commercial poultry flocks in Khouzestan province, Iran, using the polymerase chain reaction (PCR) technique. Totally, 290 tracheal swab samples were collected from 19 broiler flocks and 4 layer-breeder flocks, with or without respiratory signs, in different areas of Khouzestan province within six months.

Department of Pathobiology, Faculty of Veterinary Medicine, Urmia University, Urmia, Iran.

Avian coccidiosis is the most important parasitic disease in poultry production, which inflicts numerous losses to the industry. The extensive use of anticoccidial drugs leads to parasite resistance and drug residue in poultry products. In the present study, we aimed to investigate the effects of three famous essential oils (EOs) and their combination on inactivation of mixed oocysts of Eimeria adenoides, Eimeria dispersa, Eimeria meleagrimitis, and Eimeria meleagridis.
