Effects of Clostridium perfringens iota toxin in the small intestine of mice
(2017-12)Iota toxin is a binary toxin solely produced by Clostridium perfringens type E strains, and is structurally related to CDT from C. difficile and CST from C. spiroforme. As type E causes hemorrhagic enteritis in cattle, it ... -
Effects of deletion of the ac109 gene of Autographa californica nucleopolyhedrovirus on interactions with mammalian cells
(2017-03)Baculoviruses are able to enter into mammalian cells, where they can express a transgene that is placed under an appropriate promoter, without producing infectious progeny. ORF109 encodes an essential baculovirus protein ... -

(2016)The purpose of this study was to evaluate the activity of l-carrageenans on EHV-3 in vitro. Confluent monolayers of EDerm cells were infected with 590 plaque forming units (PFU) of EHV-3 per well, simultaneously, with ... -
Effects of Mixed Baculovirus Infections in Biological Control: A Comprehensive Historical and Technical Analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-30)Baculoviruses are insect-specific DNA viruses that have been exploited as bioinsecticides for the control of agricultural and forest pests around the world. Mixed infections with two different baculoviruses have been found ... -
Effects of superparasitism on immature and adult stages of Diachasmimorpha longicaudata Ashmead (Hymenoptera: Braconidae) reared on Ceratitis capitata Wiedemann (Diptera: Tephritidae)
(2017)The optimal use of available host by parasitoid insects should be favoured by natural selection. For solitary parasitoids, superparasitism (i.e. the egg-laying of several eggs/host) may represent a detrimental phenomenon ... -
Efficacy of a BVDV subunit vaccine produced in alfalfa transgenic plants
(Elsevier, 2013-02-15)Bovine viral diarrhea virus (BVDV) is considered an important cause of economic loss within bovine herds worldwide. In Argentina, only the use of inactivated vaccines is allowed, however, the efficacy of inactivated BVDV ... -
Efficacy of a recombinant Intimin, EspB and Shiga toxin 2B vaccine in calves experimentally challenged with Escherichia coli O157:H7
(Elsevier, 2018-06)Escherichia coli O157:H7 is a zoonotic pathogen of global importance and the serotype of Shiga toxin-producing E. coli (STEC) most frequently associated with Hemolytic Uremic Syndrome (HUS) in humans. The main STEC reservoir ... -
Efficacy of chestnut and quebracho wood extracts to control Salmonella in poultry
(Wiley, 2021-07)Aims: The study was aimed to evaluate the antibacterial activity and efficacy of chestnut and quebracho wood extracts against Salmonella by in vitro assays and in vivo trials. Methods and results: The extracts showed ... -
The efficacy of ELISA commercial kits for the screening of equine infectious anemia virus infection = Eficacia de ensayos de ELISA comerciales para el screening de infección por el virus de la anemia infecciosa equina
(Elsevier España, 2015-03)The most used and reliable indicator of equine infectious anemia virus (EIAV) infection is the detection of its specific antibodies in horse serum. In the present study, the performance of two commercial ELISA tests for ... -
Efficacy of prepartum vaccination against neonatal calf diarrhea in Nelore dams as a prevention measure
(BioMed Central, 2022-08)Background: Neonatal calf diarrhea (NCD) is the leading cause of calf morbidity and mortality in beef cattle. Cow’s vaccination in last stage of pregnancy is one of the most important measures to mitigate the risk of NCD ... -
Efficacy of the spray-drying treatment to inactivate the bovine leukemia virus in bovine colostrum
(Elsevier, 2020-07)Previous studies have shown the presence of bovine leukemia virus (BLV) in colostrum and milk of naturally infected cows. The relationship between virus or provirus and specific antibodies in these secretions is particular ... -
Efficient CRISPR/Cas9 genome editing in alfalfa using a public germplasm
(Frontiers Media, 2021-07)Because its ability to acquire large amounts of nitrogen by symbiosis, tetraploid alfalfa is the main source of vegetable proteins in meat and milk production systems in temperate regions. Alfalfa cultivation also adds ... -
Efficient edition of the bovine PRNP prion gene in somatic cells and IVF embryos using the CRISPR/Cas9 system
(2016-11)The recently developed engineered nucleases, such as zinc-finger nucleases, transcription activator-like effector nucleases, and clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated nuclease ... -
Efficient method for targeted gene disruption by homologous recombination in Mycobacterium avium subspecie paratuberculosis
