Situación epidemiológica de la criptosporidiosis bovina en Argentina

Abstract

La criptosporidiosis en terneros neonatos es causada por protozoos enteroparásitos del género Cryptosporidium. Es una afección caracterizada por cuadros de diarrea y deshidratación, dando lugar a una reducción en la producción y a las subsecuentes pérdidas económicas a productores ganaderos alrededor del mundo. La criptosporidiosis es además considerada una enfermedad zoonótica de relevancia para la salud pública ya que la ingesta de ooquistes puede ser fatal para niños, ancianos y personas inmunocomprometidas. El objetivo de este trabajo de revisión es estudiar la epidemiología de las infecciones producidas por Cryptosporidium spp. en bovinos y los factores de riesgo asociados utilizando la literatura disponible para determinar la situación en Argentina. Se determinó que la prevalencia de la infección para terneros entre 1 a 60 días de edad es variable y ronda entre 16,3 y 25,5 %. Notablemente, en un brote se encontró que 84 % de los animales estaban infectados. Estudios moleculares determinaron que C. parvum fue la única especie encontrada en terneros menores a 60 días en Argentina y se identificaron nueve subtipos diferentes pertenecientes a la familia IIa, incluyendo los subtipos zoonóticos IIaA16G1R1, IIaA17G1R1, IIaA18G1R1 y IIaA19G1R1. Se encontró también el subtipo IIaA24G1R1 como un nuevo subtipo reportado únicamente en Argentina hasta el presente. Estudios realizados en el país determinaron que la edad, la presencia de diarrea y los suelos pobremente drenados son factores de riesgo asociados a la infección por Cryptosporidium spp. Este análisis reúne información que servirá para una mayor comprensión de las características epidemiológicas y factores de riesgo, ayudando a la prevención y desarrollo de estrategias de control para la criptosporidiosis bovina.

Cryptosporidiosis in neonatal calves is caused by enteroparasites of the genus Cryptosporidium. This infectious disease is characterized by diarrhea and dehydration, leading to a reduction in production, causing economic losses in meat and dairy farming around the world. In addition, cryptosporidiosis is considered a zoonotic disease of relevance to public health since the ingestion of oocysts can be fatal for children, the elderly and immunocompromised people. The objective of this review is to determine the situation of the epidemiology of C. parvum-infections in cattle and associated risk factors in Argentina, based on the literature of recent studies. The prevalence of infection for calves between 1 to 60 days of age was determined to range between 16.3 and 25.5 %. Noteworthy, in a single outbreak, 84 % of calves were found to be infected. Molecular studies determined that C. parvum was the only species found in calves younger than 60 days of age in Argentina and altogether nine subtypes of the IIa family were identified, including the zoonotic subtypes IIaA16G1R1, IIaA17G1R1, IIaA18G1R1 and IIaA19G1R1. Among them, the IIaA24G1R1 subtype has been exclusively reported in this country so far. Studies carried out in Argentina determined that age, occurrence of diarrhea and poorly drained soils are risk factors associated with infection by Cryptosporidium spp. This analysis gathers information that will aid to understand the epidemiological characteristics and risk factors, facilitating the prevention and development of control strategies for bovine cryptosporidiosis.
