The aim of this study was to determine the presence of Cotylophorum sp in cattle in six districts of the province of Moyobamba, Peru. A total of 411 faecal samples of cattle aged 1.5 to 8 years between October and November 2011 were collected. The samples were processed by the method of feacal sedimentation. The results showed the presence of eggs of Cotylophoron sp, with a prevalence of 55%. No statistically difference was found between the variables age, sex and place of origin and the presence of Cotylophoron sp.

La prueba de hibridación de ácidos nucleicos ha permitido al INIA, identificar plantas madres de palto libres de ASBVd y PSTVd, a partir del cual se están generando material de propagación de calidad para los viveristas. esperamos que este trabajo brinde el soporte tecnológico en el tema de sanidad a las futuras actividades de agro exportación.

Siembras comerciales de maíz Asgrow 7573 (AS 7573) en los municipios de Tlalixcoyan, Paso de Ovejas y Cosoleacaque, Veracruz, México, en 2006-2007 presentaron una enfermedad caracterizada por manchas pequeñas en hojas, irregulares, de aspecto húmedo, que se extendieron a lo largo de la lámina foliar, formando rayas translúcidas, que se tornaban de color blanco-pajizo. Frecuentemente, el tejido presentó desgarramiento y aspecto atizonado. En ocasiones se observó una pudrición en las espigas envueltas por hojas enfermas. En algunas de las plantas con síntomas se hicieron cortes transversales de los tallos y se observó necrosis vascular. En los medios de cultivo BK, AN y CPG se aislaron en todos los casos colonias bacterianas color blanco, redondas y convexas. La patogenicidad se confirmó en plántulas sanas de maíz. Las cepas bacterianas se identificaron como Acidovorax avenae...

This work evaluated the effectiveness of combining grafted bell pepper and metam sodium fumigated soil to reduce the incidence of Phytophthora root and crown rot, a disease that significantly reduces crop yields. The experiment was carried out during 2011 in Chihuahua, Mexico. Six trials were established in a previously fumigated soil using ‘Facinato’ variety grafted onto ‘Robusto’ and ‘Terrano’ rootstocks, besides four self-rooted varieties. To identify the pathogen, ribosomal loci corresponding to the ITS region were amplified and sequenced. The general linear model described the increase in disease incidence in all trials. Grafted plants had a lower slope of disease incidence than the four self-rooted varieties. Results indicated that final disease incidence (Yf) of the varieties ranged 37-69%, while grafted plants exhibited a Yf of only 13-16%. Fumigation caused a better ...
