Numerosos estudios indican que Chlamydia abortus<\/em> es uno de los principales pat\u00f3genos a nivel mundial que causan abortos en ovino y caprino. No obstante, es muy com\u00fan la ausencia de datos a nivel local. En este art\u00edculo, vamos a mirar con detalle la prevalencia de C. abortus<\/em> en Canad\u00e1 bas\u00e1ndonos en los resultados de dos estudios. \u00bfCu\u00e1l ser\u00e1 su importancia real?<\/div>\n

Estudio en Quebec<\/h2>\n

El Ministerio de Agricultura, Pesca y Alimentaci\u00f3n de Quebec<\/strong>, realiz\u00f3 entre 2017 y 2019 la primera campa\u00f1a \u201cPISAQ<\/a>\u201d. El objetivo era concienciar<\/strong> sobre los problemas abortivos<\/strong><\/a> en peque\u00f1os rumiantes, y conseguir muestras para un posterior estudio epidemiol\u00f3gico<\/strong><\/a>.<\/p>\n

Participaron un total de 300 granjas de ovino y caprino<\/strong> con problemas reproductivos, y se pudieron analizar en el laboratorio cerca de 100 episodios<\/strong> de abortos experimentados en 88 granjas.<\/p>\n

Gracias a la campa\u00f1a se pudieron identificar los principales pat\u00f3genos<\/strong> causantes de abortos en Quebec, y de esta manera se pudieron establecer las mejores medidas<\/strong><\/a> para controlarlos. \u00a0<\/strong><\/p>\n

Chlamydia abortus se identific\u00f3 en el 18% de las muestras, siendo el pat\u00f3geno m\u00e1s prevalente<\/p><\/blockquote>\n

Identificaci\u00f3n de C. abortus mediante PCR<\/h2>\n

En otro estudio realizado en la Universidad de Guelph<\/a> (Ontario, Canad\u00e1) y publicado en el Journal of Veterinary Diagnostic Investigation, tambi\u00e9n se demostr\u00f3 la importancia de Chlamydia abortus<\/em><\/strong><\/a> en Canad\u00e1.<\/p>\n

El estudio se realiz\u00f3 entre 2009 y 2011, y se analizaron 163 muestras de oveja y 96 de cabra. Las muestras eran placentas y fetos<\/strong> recogidas despu\u00e9s de un aborto, y se les realiz\u00f3 un examen macrosc\u00f3pico<\/strong> y posteriormente PCR.<\/strong><\/p>\n

Los resultados de las PCR<\/strong> fueron:<\/p>\n

– Oveja<\/strong>: 42 muestras positivas de 162<\/p>\n

– Cabra<\/strong>: 54 muestras positivas de 92<\/p>\n

El 26% de muestras de ovejas y 59% de cabra fueron positivas a C. abortus.<\/p><\/blockquote>\n

Teniendo en cuenta el historial del caso y otras pruebas adicionales (histolog\u00eda, inmunohistoqu\u00edmica y bacteriolog\u00eda) se concluy\u00f3 que C. abortus<\/em> era la causa de aborto en el 38% y 63% de los casos<\/strong> de oveja y cabra que hab\u00edan dado positivo en la PCR, respectivamente.<\/p>\n

Los resultados demuestran que C.abortus es el pat\u00f3geno m\u00e1s prevalente y el principal causante de abortos en oveja y cabra.<\/p><\/blockquote>\n

Conclusiones<\/h2>\n

Seg\u00fan los resultados de estos estudios podemos decir que Chlamydia abortus<\/em><\/strong> es un problema significativo en Canad\u00e1. Por lo tanto, es necesario tomar medidas para controlar <\/strong>la enfermedad, como buenas pr\u00e1cticas de manejo y bioseguridad<\/strong> y la vacunaci\u00f3n<\/strong><\/a>.<\/p>\n

Es necesario seguir investigando la prevalencia C.abortus para desarrollar estrategias efectivas de prevenci\u00f3n y control<\/p><\/blockquote>\n
