Updating of the bovine neosporosis

Abstract

In the fields of Medicine and bovine production, there is a wide variety of diseases affecting reproduction, in relation to the number of live births, the interval between births and open days, among others. Some of these diseases produce abortions and embryonic death, which explain the alteration of reproductive parameters. Many of these diseases have an infectious origin, such as parasites, bacteria, viruses and fungi, which are transmitted among animals. Besides, some of them have zoonotic features that generate problems to human health. Among these agents, the Neospora caninum, protozoan stands out. Its life cycle is fulfilled in several species of animals like the dog and the coyote. These two act as its definitive hosts and the cattle as its intermediary host. The Neospora caninum causes in the infected animals, reproductive disorders, clinical manifestations and decreased production which affects productivity of small, medium and large producers. Because of this, diagnostic techniques that allow understanding the epidemiological behavior of this disease have been developed. However in spite of being a major agent in the bovine reproductive health, few studies have been undertaken to determine the prevalence of this agent around the world. Therefore, the objective of this review was to collect updated information on the behavior of this parasite, targeting its epidemiology, its symptoms, its impact on production and the methods of its control and prevention.
