Flashcards

What is coccidiosis?

A parasitic disease caused by protozoa from the Apicomplexa class, affecting various animals including birds, cattle, rabbits, humans, dogs, cats, pigs, and horses.

What are the pathogens causing coccidiosis?

The causative agents of coccidiosis are parasites belonging to the genera Eimeria and Isospora.

Who is most susceptible to coccidiosis?

Coccidiosis commonly occurs in young animals, particularly those in stressful environments.

What factors contribute to coccidiosis?

Stressful conditions such as overcrowding or intensive farming practices are associated with an increased risk of coccidiosis.

How do sporozoites enter the body?

Sporozoites, the infectious stage of the parasite, are released in the intestines and penetrate the intestinal lining.

What happens after fertilization?

After fertilization, the zygote develops a protective outer shell, forming an immature oocyst, which is released in the feces of infected animals.

Study Notes

Definición y Causas de la Coccidiosis

  • La coccidiosis es una enfermedad parasitaria producida por el protozoo apicomplexa.
  • El agente etiológico de la coccidiosis son Eimeria sp e Isospora sp.

Condiciones de Presentación

  • La coccidiosis se presenta generalmente en animales jóvenes.
  • Se presenta en animales bajo condiciones de alto hacinamiento o explotaciones intensivas.

Efectos de la Coccidiosis

  • Induce destrucción celular.
  • Puede producir diarrea, depende de dosis y otros factores.

Ciclo de Vida

  • Los esporozoítos se liberan en el intestino y penetran en la mucosa donde se multiplican asexuadamente en una estructura denominada meronte.
  • Los microgametos fecundan los macrogametos y el cigoto se rodea de una cubierta externa resistente formando un ooquiste resistente.
  • El hospedero ingiere un ooquiste esporulado en el alimento o agua.
  • Los merozoitos de 1ª generación hacen estallar la célula invadiendo células epiteliales.

Síntomas

  • Los signos coinciden con inicio de diarrea.
