What is equine piroplasmosis?

Equine Piroplasmosis is a blood-borne protozoal infection of horses caused by Theileria (Babesia) equi and/or Babesia caballi.

How is piroplasmosis treated?

The most commonly used treatment is imidocarb. In the case of infection by the protozoan Babesia caballi, your veterinarian will give 2 injections of imidocarb 24 hours apart. In the case of infection with Theileria equi, the treatment will consist of 4 injections at 72 hour intervals, as this form is more resistant.

How is piroplasmosis diagnosed?

Equine piroplasmosis can sometimes be diagnosed by detecting the organisms in blood or organ smears stained with Romanowsky-type stains such as Giemsa, Wright’s or Diff-Quik®. Blood smears are optimally made from superficial skin capillaries during the acute phase of the disease.

How is piroplasmosis spread?

The disease is transmitted via ticks or through mechanical transmission by improperly sanitized surgical, dental or tattoo instruments, through the reuse of needles and syringes, or through the administration of contaminated blood products.

Which parasites are included in piroplasmosis?

Equine Piroplasmosis (EP) is a tick-borne disease caused by apicomplexan protozoan parasites, Babesia caballi and Theileria equi.

Can horses get Babesia?

Babesiosis (piroplasmosis) is a tick-borne protozoan parasitic disease affecting red blood cells. Horses may be infected with Babesia caballi or Theileria equi (formerly known as Babesia equi). Typical signs of acute babesiosis include fever (39° to 42°C), hemolytic anemia, and jaundice.

What is bovine piroplasmosis?

Bovine babesiosis is a tick-borne disease of cattle caused by apicomplexan protozoa of the genus Babesia which may induce clinical conditions characterized by hemolytic anemia and fever, with occasional hemoglobinuria and even death of animals.

What is Imidocarb dipropionate?

Imidocarb dipropionate (brand name Imizol®) is a drug used to treat infections caused by protozoa (single-celled organisms that sometimes cause disease). For example, it is used to treat the infection babesiosis in dogs. This infection is caused by the protozoa Babesia which is transferred to pets from tick bites.

Can Babesia cause constipation?

People with Babesia will either have trouble starting their urinary stream or will go through episodes of incontinence. They may also have problems with bowel motility; usually constipation, but can also sometimes have diarrhea due to autonomic nervous system de-regulation.

Trypanosoma congolense are extracellular and intravascular blood parasites that cause debilitating acute or chronic disease in cattle and other domestic animals. Diminazene aceturate (Berenil) has been widely used as a chemotherapeutic agent for trypanosomiasis in livestock since 1955.

What is Equ equine piroplasmosis?

Equine piroplasmosis is the most common protozoan disease of horses. The protozoan genus Babesia is a member of the Piroplasmida, a constituent group of the Apicomplexa. When a tick intermediate host ingests infected blood, the parasite babesia enters the gut epithelium and multiply by schizogony, forming organisms known as vermicules.

Can Dermacentor variabilis transmit piroplasmosis to horses?

Dermacentor variabilis tick on a horse. This tick species was implicated in the transmission of equine piroplasmosis in 2009 in Texas along with Amblyomma cajennense ticks (cayenne ticks). (D2312-1)

“Our group identified the cayenne tick, Amblyomma cajennense, as the predominant tick species found on horses at the ranch,” says Knowles.

Can piroplasmosis spread in the United States?

“Discovering that this tick species is present in the United States and is capable of spreading piroplasmosis is a crucial development in helping horse ranchers and traders in their quest to keep the United States free of this debilitating disease,” says Knowles.—By Sharon Durham, Agricultural Research Service Information Staff.
