Descripción de la Trypanosomiasis en equinos, transmisión y enfermedad

The Trypanosoma equiperdum is a parasite that affects the entire equine species, causing a sexual transition disease known as dourine or mal coitus. This is a difficult parasite to diagnose in biochemical blood tests, so the most effective way to diagnose it is through tests based on urine samples. The most infected are the male stallions, followed by the mares, one of the signs that stands out the most is their excessive sexual appetite and their pathognomonic sign, which are skin plaques also known as dollar coins. This parasite presents various stages of development that are trypomastigote, epimastigote, promastogote, and amastigote. its transmission is clearly sexual, and on exceedingly rare or few occasions it is transmitted by an intermediate host such as the fly, the horsefly and the mosquito. Trypanosoma equiperdum is a parasite that does not have a vaccine as a prevention method, but it does have a specific treatment to control it and the symptoms that the horse is presenting at the time. In the case of horses, it is extremely easy to diagnose because the signs can be differentiated with the naked eye, but in the donkey, we do not have the same facility since it is asymptomatic and does not present any type of sign to rule out or be able to carry out the proper treatment. For this reason, as previously mentioned, the donkey presents a profoundly severe problem for other equines that are close to its habitat or environment, since it is a very high source of contagion. This protozoan has a Cosmopolitan distribution, which is to say that it is very wide worldwide, we can find it in countries like Mexico, and even Russia and part of Africa and Central and South America. Trypanosoma equiperdum comes from the family of protozoa TRYPANOSOMATIDAE and the genus Trypanosoma gruby. The development of Trypanosoma equiperdum occurs from three phases, the first begins with edema, the second with appearances of urticarial and the third culminates in paralysis. This disease has a slow but very harmful progress to the health and well-being of the horses that may contract it, its pathogenic activity begins a week after its contagion in horses, it may even take months to start or to appear the symptoms and clinical signs.
