Clostridium perfringens epsilon toxin induces permanent neuronal degeneration and behavioral changes
(2017-05)Clostridium perfringens epsilon toxin (ETX), the most potent toxin produced by this bacteria, plays a key role in the pathogenesis of enterotoxaemia in ruminants, causing brain edema and encephalomalacia. Studies of animals ... -
Diversity and distribution of lepidoptera-specific toxin genes in Bacillus thuringiensis strains from Argentina
(2017-05)A total of 268 Bacillus thuringiensis strains obtained from different sources of Argentina were analyzed to determine the diversity and distribution of the cry1, cry2, cry8, cry9 and vip3A genes encoding for lepidopteran-specific ... -
BOLA-DRB3 gene polymorphisms influence bovine leukaemia virus infection levels in Holstein and Holstein × Jersey crossbreed dairy cattle
(2017-05)Bovine leukemia virus (BLV) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter-individual variation in the level of ... -
The localization of a heterologous displayed antigen in the baculovirus-budded virion determines the type and strength of induced adaptive immune response
(2017-05)In the search of strategies of presentation of heterologous antigens to elicit humoral or cellular immune responses that modulate and properly potentiate each type of response, researchers have been studying baculovirus ... -
Achiote (Bixa orellana L.) : a natural source of pigment and vitamin E
(Springer, 2017-05)Commercialization of agricultural products, including seeds and its derived products, represents an important economic source for developing countries. Natural colorants obtained from the seeds of achiote plant (annatto) ... -
Bovine colostral cells : the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)Because bovine maternal and fetal blood supplies are kept separate in utero, calves are immunologically naïve immediately after birth, which puts them at high risk for disease. The acquisition of passive immunity, generally ... -
Bovine colostral cells—the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)At birth, neonatal calves have all the essential immune components they need as adult cattle; however, it takes at least 2 to 4 weeks for those components to become fully functional.1,2 The immune system does not become ... -
Genome-wide identification of microRNA targets in the neglected disease pathogens of the genus Echinococcus
(2017-06)MicroRNAs (miRNAs), a class of small non-coding RNAs, are key regulators of gene expression at posttranscriptional level and play essential roles in biological processes such as development. MiRNAs silence target mRNAs by ... -
Genetic entanglement between Cercospora species associating soybean purple seed stain
(2017-06)Soybean purple seed stain (S-PSS) is a destructive, worldwide distributed fungal disease caused by several Cercospora species. This work aims to shed light on the nature of the genealogical and genetic relationships amongst ... -
Bacillus thuringiensis: ¿nuevas aplicaciones para un viejo conocido?
(2017-06)Bacillus thuringiensis (B. thuringiensis) se caracteriza principalmente por producir durante la esporulación una inclusión parasporal formada por uno o más cuerpos cristalinos de naturaleza proteica, que son selectivamente ... -
Prevención y tratamiento de Rotavirus A mediante nanoanticuerpos VHH anti-VP6
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2017-06)La diarrea asociada a Rotavirus A (RVA) representa una de las principales causas de mortalidad infantil a nivel mundial. Si bien la vacunación masiva contra RVA ha logrado disminuir significativamente las muertes causadas ... -
Seroprevalencia de infección por el virus de leucosis bovina durante 2015 en rodeos de cría de la Zona Deprimida del Río Salado, provincia de Buenos Aires, Argentina
(2017-06)La leucosis enzoótica bovina (LEB) es una enfermedad crónica, linfoproliferativa y altamente contagiosa producida por el virus de la leucosis bovina (VLB). La sangre es una fuente importante de infección, principalmente ... -
Responses of Rhopalosiphum padi (L.) (Homoptera: Aphididae) on different wheat cultivars under laboratory conditions
(2017-06)Bird cherry-oat aphid, Rhopalosiphum padi (L.), a polyphagous species with a worldwide distribution, is an important pest of wheat as well as the main vector of barley yellow dwarf virus. The development, survivorship, and ... -
A closed-tube loop-mediated isothermal amplification assay for the visual endpoint detection of Brucella spp. and Mycobacterium avium subsp. paratuberculosis
(Springer, 2017-06)LAMP (loop-mediated isothermal amplification) is an isothermal nucleic acid amplification technique that is characterized by its efficiency, rapidity, high yield of final product, robustness, sensitivity, and specificity, ... -
Genome-wide identification of the mutation uderlying fleece variation and discriminating ancestral hairy species from modern woolly sheep
(Oxford university press, 2017-07)The composition and structure of fleece variation observedin mammals is a consequence of a strong selective pressure for fiber production after domestication. In sheep, fleece variation discriminates ancestral species ... -
Draft genome sequences of two mycobacterium bovis strains isolated from beef cattle in Paraguay
(2017-07)This work reports the draft genome sequences of the Mycobacterium bovis strains M1009 and M1010, isolated from the lymph nodes of two infected cows on a beef farm in Paraguay. Comparative genomics between these strains and ... -
Bacillus thuringiensis and their endophytic capabilities
(2017-07)The main characteristic of Bacillus thuringiensis is that during sporulation produces a parasporal inclusion formed by one or more proteinaceous bodies that exhibit insecticidal activity upon ingestion by susceptible ... -
