Zoonotic pathogens cause of animal abortion and fetal loss

Abortion is one of the most common disorders that decrease reproductive performance in animals, and it results in considerable economic loss to the industry. A wide range of agents, either infectious or noninfectious, can be the cause of abortion. It seems that infectious agents of abortion are more frequent than non-infectious ones in the domestic animals. Some of the infectious agents are zoonotic that could transmit from animals to humans and have an important impact on human health. Several infectious agents can cause severe disease in humans. So, besides to economic loss of abortion in the herd, its zoonotic implications regard to human consumption of farm animal products or keeping pets must be considered. The infectious agents, such as Brucella spp , Campylobacter spp ., Listeria monocytogenes, Leptospira spp., Aspergillus, Toxoplasma gondii, Chlamydia spp ,and Coxiella burnetii are zoonotic pathogens that cause abortion in the animals. This article provides a review of the zoonotic pathogens responsible for animal abortion. Parameters necessary for disease recognition and diagnosis in humans and animals, reservoirs of infection and transmission mode, and their treatment are emphasized and described that it can help reduce the risk of increasing of zoonotic disease.
