Assessing the hidden diversity underlying consensus sequences of SARS-CoV-2 using VICOS, a novel bioinformatic pipeline for identification of mixed viral populations por Goya, Stephanie, Sosa, Ezequiel Jorge, Nabaes Jodar, Mercedes Soledad, Torres, Carolina, Konig, Guido Alberto, Acuña, Dolores, Ceballos, Santiago, Distefano, Ana Julia, Dopazo, Hernán, Dus Santos, Maria Jose, Fass, Monica Irinia, Fernandez Do Porto, Darío Augusto, Fernandez, Ailen, Gallego, Fernando, Gismondi, Maria Ines, Gramundi, Ivan, Lusso, Silvina, Marti, Marcelo Adrián, Mazzeo, Melina, Mistchenko, Alicia Susana, Muñoz Hidalgo, Marianne Graziel, Natale, Mónica, Nardi, Cristina, Ousset, Julia, Peralta, Andrea Veronica, Pintos, Carolina, Puebla, Andrea Fabiana, Pianciola, Luis, Rivarola, Maximo Lisandro, Turjanski, Adrián, Valinotto, Laura, Vera, Pablo Alfredo, Zaiat, Jonathan, Zubrycki, Jeremias Enrique, Aulicino, Paula, Viegas, Mariana

“…Although next generation sequencing methods are very sensitive to detect heterogeneous viral populations in a sample, there is no standardized method for their characterization, so their clinical and epidemiological importance is unknown. Material and methods: We developed VICOS (Viral COinfection Surveillance), a new bioinformatic algorithm for variant calling, filtering and statistical analysis to identify samples suspected of being mixed SARS-CoV-2 populations from a large dataset in the framework of a community genomic surveillance. …”

Performance of outbreak management plans for emerging plant diseases: the case of almond leaf scorch caused by Xylella fastidiosa in mainland Spain por Cendoya, Martina, Lázaro, Elena, Navarro-Quiles, Ana, López-Quílez, Antonio, Conesa, David, Vicent, Antonio

“…As a case study, the disease dynamics of almond leaf scorch, caused by Xylella fastidiosa (Xf), in the affected area of Alicante, Spain, were approximated using an individual-based spatial epidemiological model. The emergence of this outbreak was dated based on phylogenetic studies, and official surveys were used to delimit the current extent of the disease. …”

Impact of novel methods and research approaches in plant pathology: Are individual advances sufficient to meet the wider challenges of disease management? por Jeger, Michael, Beresford, Robert, Berlin, Anna, Bock, Clive, Fox, Adrian, Golding, Kaitlin, Newton, Adrian C., Vicent, Antonio, Xu, Xiangming

“…Deployment of host resistance in the field needs to be aligned with a greater appreciation of plant genetic diversity and the complementary contribution made by tolerance of disease. Epidemiological understanding of the spatiotemporal spread of plant diseases has improved through population dynamic and genetic analyses. …”

Seed transmission of maize downy mildew (Peronosclerospora sorghi) in Nigeria por Adenle, V.O., Cardwell, K.F.

“…Transmission of disease to seedlings was observed when the silk‐inoculated seeds (9% moisture content) were planted in pots in a greenhouse; however, no disease transmission was observed when such seeds were planted in the field. The epidemiological significance of seed transmission is discussed with particular reference to survival of inoculum and development of epidemics. …”
