Cytogenetic analysis of the South American fruit fly Anastrepha fraterculus (diptera:tephritidae) species complex : construction of detailed photographic polytene chromosome maps of the Argentinian af. sp.1 member
(2016)Genetic and cytogenetic studies constitute a significant basis for understanding the biology of insect pests and the design and the construction of genetic tools for biological control strategies. Anastrepha fraterculus ... -
Dissecting maize diversity in lowland South America : genetic structure and geographic distribution models
(2016)Background: Maize landraces from South America have traditionally been assigned to two main categories: Andean and Tropical Lowland germplasm. However, the genetic structure and affiliations of the lowland gene pools have ... -
Epidemiological and virological findings during multiple outbreaks of equine influenza in South America in 2012
(2016-01)Background: In 2012, equine influenza (EI) virus was confirmed as the cause of outbreaks of respiratory disease in horses throughout South America. In Uruguay and Argentina, hundreds of vaccinated thoroughbred horses in ... -
First identification of bacterial endosymbionts in three South-American spittlebug pests: Notozulia entreriana, Deois mourei and Deois knoblauchii
(Alma Mater Studiorum, Università di Bologna, 2022-06)Spittlebugs cause major pasture damage in the Neotropics. As most xylem-feeders, they depend on microbial symbionts to supply essential amino acids to their diet. Here, the obligate nutritional endosymbiont ‘Candidatus ... -
First record of males of the invasive eucalyptus pest species Leptocybe invasa Fisher & LaSalle, 2004 (Hymenoptera: Eulophidae: Tetrastichinae) from South America
(Forschungs Museum Koenig, 2019-12)The “blue gum chalcid”, Leptocybe invasa is a pest of eucalyptus worldwide. It has an Australian origin and has expanded into Asia, Europe, Africa and America. L. invasa females were reported from South America in the last ... -
Genetically diverse herpesviruses in South American Atlantic coast seabirds
(2017)Different herpesviruses have been associated with respiratory and enteric disease and mortality among seabirds and waterfowl. In 2011, a respiratory disease outbreak affected 58.3% (98/168) of the Magellanic penguins ... -
Identification and molecular characterization of Orf virus infection in occupationally exposed women in South America
(Elsevier, 2023-06)Contagious Ecthyma (CE) is a severe exanthematous dermatitis caused by the Orf virus (ORFV) that mainly affects domestic small ruminants such as sheep and goats. It is a worldwide-distributed occupational zoonosis, ... -
Molecular epidemiology and spatio-temporal dynamics of the H3N8 equine influenza virus in South America
(2016)Equine influenza virus (EIV) is considered the most important respiratory pathogen of horses as outbreaks of the disease lead to substantial economic losses. The H3N8 EIV has caused respiratory disease in horses across the ... -
Molecular identification of Anaplasma marginale in two autochthonous South American wild species revealed an identical new genotype and its phylogenetic relationship with those of bovines
(2016)Background: Anaplasma marginale is a well-known cattle pathogen of tropical and subtropical world regions. Even though, this obligate intracellular bacterium has been reported in other host species different than bovine, ... -
Origin of new lineages by recombination and mutation in avian infectious bronchitis virus from South America
(MDPI, 2022-10)The gammacoronavirus avian infectious bronchitis virus (IBV) is a highly contagious respiratory pathogen of primary economic importance to the global poultry industry. Two IBV lineages (GI-11 and GI-16) have been widely ... -
Sarcocystis spp. of new and old world camelids : ancient origin, present challenges
(MDPI, 2024-03)Sarcocystis spp. are coccidian protozoans belonging to the Apicomplexa phylum. As with other members of this phylum, they are obligate intracellular parasites with complex cellular machinery for the invasion of host cells. ... -
South American H4N2 influenza A virus improved replication in chicken trachea after low number of passages
(Frontiers Media, 2023-05)Introduction of influenza A viruses (FLUAV) into poultry from waterfowl is frequent, producing economic burden and increasing the probability of human infections. We have previously described the presence of FLUAV in wild ... -
Susceptibility of agricultural pests of regional importance in South America to a Bacillus thuringiensis Cry1Ia protein
(Elsevier, 2020-05)Bacillus thuringiensis toxins of the Cry1I class have dual specificity for insects in the orders Coleoptera and Lepidoptera. We assessed the toxicity of a Cry1Ia protein from an Argentinian B. thuringiensis strain against ... -
The origin and genetic diversity of the causal agent of Asian soybean rust, Phakopsora pachyrhizi, in South America
(Wiley, 2015-06)A sequence‐based approach was used to investigate molecular genetic variations in Phakopsora pachyrhizi, an obligate biotrophic pathogen that causes Asian soybean rust. In Argentina, the samples came from uredinium‐bearing ...
