Analagous population structures for two alphabaculoviruses highlight a functional role for deletion mutants
Serrano García, Amaya ; Williams, Trevor ; Simón de Goñi, Oihane ; López Ferber, Miguel; Caballero Murillo, Primitivo ; Muñoz Labiano, Delia (American Society for Microbiology, 2012) Artículo / ArtikuluaA natural Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) isolate from Florida shares a strikingly similar genotypic composition to that of a natural Spodoptera frugiperda MNPV (SfMNPV) isolate from Nicaragua. ... -
Expression of a peroral infection factor determines pathogenicity and population structure in an insect virus
Simón de Goñi, Oihane ; Williams, Trevor ; Cerutti, Martine; Caballero Murillo, Primitivo ; López Ferber, Miguel (Public Library of Science, 2013) Artículo / ArtikuluaA Nicaraguan isolate of Spodoptera frugiperda multiple nucleopolyhedrovirus is being studied as a possible biological insecticide. This virus exists as a mixture of complete and deletion genotypes; the latter depend on ... -
Functional importance of deletion mutant genotypes in an insect nucleopolyhedrovirus population
Simón de Goñi, Oihane ; Williams, Trevor ; López Ferber, Miguel; Caballero Murillo, Primitivo (American Society for Microbiology, 2005) Artículo / ArtikuluaA Nicaraguan isolate of a nucleopolyhedrovirus (SfNIC) that attacks the fall armyworm, Spodoptera frugiperda, survives as a mixture of nine genotypes (SfNIC A to I) that all present genomic deletions, except variant B ... -
Gender-mediated differences in vertical transmission of a nucleopolyhedrovirus
Virto Garayoa, Cristina ; Zárate Chaves, Carlos Andrés; López Ferber, Miguel; Murillo Pérez, Rosa ; Caballero Murillo, Primitivo ; Williams, Trevor (Public Library of Science, 2013) Artículo / ArtikuluaWith the development of sensitive molecular techniques for detection of low levels of asymptomatic pathogens, it becoming clear that vertical transmission is a common feature of some insect pathogenic viruses, and likely ... -
Genetic structure of a Spodoptera frugiperda nucleopolyhedrovirus population: high prevalence of deletion genotypes
Simón de Goñi, Oihane ; Williams, Trevor ; López Ferber, Miguel; Caballero Murillo, Primitivo (American Society for Microbiology, 2004) Artículo / ArtikuluaA Nicaraguan field isolate (SfNIC) of Spodoptera frugiperda nucleopolyhedrovirus was purified by plaque assay on Sf9 cells. Nine distinct genotypes, A to I, were identified by their restriction endonuclease profiles. Variant ... -
Mixtures of complete and pif1- and pif2-deficient genotypes are required for increased potency of an insect nucleopolyhedrovirus
Clavijo Palacios, Gabriel ; Williams, Trevor ; Simón de Goñi, Oihane ; Muñoz Labiano, Delia ; Cerutti, Martine; López Ferber, Miguel; Caballero Murillo, Primitivo (American Society for Microbiology, 2009) Artículo / ArtikuluaThe insecticidal potency of a nucleopolyhedrovirus population (SfNIC) that infects Spodoptera frugiperda (Lepidoptera) is greater than the potency of any of the component genotypes alone. Occlusion bodies (OBs) produced ... -
Nucleopolyhedrovirus coocclusion technology: a new concept in the development of biological insecticides
Williams, Trevor ; López Ferber, Miguel; Caballero Murillo, Primitivo (Frontiers Media, 2022) Artículo / ArtikuluaNucleopolyhedroviruses (NPV, Baculoviridae) that infect lepidopteran pests have an established record as safe and effective biological insecticides. Here, we describe a new approach for the development of NPV-based ... -
Optical brighteners do not influence covert baculovirus infection of Spodoptera frugiperda
Martínez Castillo, Ana Mabel ; Williams, Trevor ; López Ferber, Miguel; Caballero Murillo, Primitivo (American Society for Microbiology, 2005) Artículo / ArtikuluaCovert infection with Spodoptera frugiperda multiple nucleopolyhedrovirus, detected by reverse transcription-PCR of virus gene transcripts (ie-0 and polh), was not significantly affected by the presence of an optical ... -
The sf32 unique gene of spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a non-essential gene that could be involved in nucleocapsid organization in occlusion-derived virions
Beperet Arive, Inés ; Barrera Cubillos, Gloria Patricia; Simón de Goñi, Oihane ; Williams, Trevor ; López Ferber, Miguel; Gasmi, Laila; Herrero, Salvador; Caballero Murillo, Primitivo (Public Library of Science, 2013) Artículo / ArtikuluaA recombinant virus lacking the sf32 gene (Sf32null), unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV), was generated by homologous recombination from a bacmid comprising the complete viral genome ... -
Stability of a Spodoptera frugiperda nucleopolyhedrovirus deletion recombinant during serial passage in insects
Simón de Goñi, Oihane ; Williams, Trevor ; Possee, Robert D.; López Ferber, Miguel; Caballero Murillo, Primitivo (American Society for Microbiology, 2009) Artículo / ArtikuluaThe stabilities of the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) complete genome bacmid (Sfbac) and a deletion recombinant (Sf29null) in which the Sf29 gene was replaced by a kanamycin resistance ... -
Superinfection exclusion in alphabaculovirus infections is concomitant with actin reorganization
Beperet Arive, Inés ; Irons, Sarah L.; Simón de Goñi, Oihane ; King, Linda A.; Williams, Trevor ; Possee, Robert D.; López Ferber, Miguel; Caballero Murillo, Primitivo (American Society for Microbiology, 2014) Artículo / ArtikuluaSuperinfection exclusion is the ability of an established virus to interfere with a second virus infection. This effect was studied in vitro during lepidopteran-specific nucleopolyhedrovirus (genus Alphabaculovirus, family ...
