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 ... -
Intrinsic and extrinsic factors related to pathogen infection in wild small mammals in intensive milk cattle and swine production systems
(2017)Background: Understanding the ecological processes that are involved in the transmission of zoonotic pathogens by small mammals may aid adequate and effective management measures. Few attempts have been made to analyze ... -
A haplotype at intron 8 of PTPRT gene is associated with resistance to Brucella infection in Argentinian creole goats
(2017-08)Brucellosis is the leading zoonosis on a worldwide scale and constitutes a major public health threat in many regions of the world. Several molecular markers associated with natural resistance to intracellular bacterial ... -
Molecular characterization of Cryptosporidium isolates from calves in Argentina
(2013-12)Cryptosporidiosis is responsible for significant fatalities of neonatal calves, resulting in substantial economic loss in dairy farming in several countries. Additionally, the high shedding of environmentally resistant ... -
Evidence for extensive genetic diversity and substructuring of the Babesia bovis metapopulation
(2013-11)Babesia bovis is a tick-transmitted haemoprotozoan and a causative agent of bovine babesiosis, a cattle disease that causes significant economic loss in tropical and subtropical regions. A panel of nineteen micro- and ... -
The glycosylphosphatidylinositol-anchored protein repertoire of Babesia bovis and its significance for erythrocyte invasion
(2014-04)Glycosylphosphatidylinositol-anchored proteins are abundant on the surface of pathogenic protozoans and might play an important role for parasite survival. In the present work, the relevance of GPI-anchored proteins for ... -
Reclassification of Theileria annae as Babesia vulpes sp. nov.
(2015-04)Background: Theileria annae is a tick-transmitted small piroplasmid that infects dogs and foxes in North America and Europe. Due to disagreement on its placement in the Theileria or Babesia genera, several synonyms have ... -
Methodology for the assessment of brucellosis management practices and its vaccination campaign : example in two Argentine districts
(2017-09)Background: In Argentina, vaccination with Brucella abortus Strain 19 vaccine is mandatory. The objective of the study was to develop and test a method for evaluating, in an innovative way, some farmers’ and veterinarian ... -
Shiga toxin-producing Escherichia coli (STEC) O22:H8 isolated from cattle reduces E. coli O157:H7 adherence in vitro and in vivo
(2017-09)Problem addressed: Shiga toxin-producing Escherichia coli (STEC) are a group of bacteria responsible for foodassociated diseases. Clinical features include a wide range of symptoms such as diarrhea, hemorrhagic colitis and ... -
Caprine brucellosis : a historically neglected disease with significant impact on public health
(2017-08)Caprine brucellosis is a chronic infectious disease caused by the gram-negative cocci-bacillus Brucella melitensis. Middle- to late-term abortion, stillbirths, and the delivery of weak offspring are the characteristic ... -
Systems biology analysis of temporal in vivo Brucella melitensis and bovine transcriptomes predicts host : pathogen protein–protein interactions
(2017-07)To date, fewer than 200 gene-products have been identified as Brucella virulence factors, and most were characterized individually without considering how they are temporally and coordinately expressed or secreted during ... -
Molecular detection and phylogenetic analysis of Hepatozoon spp. in questing Ixodes ricinus ticks and rodents from Slovakia and Czech Republic
(2016-10)By amplification and sequencing of 18S rRNA gene fragments, Hepatozoon spp. DNA was detected in 0.08 % (4/5057) and 0.04 % (1/2473) of questing Ixodes ricinus ticks from Slovakia and Czech Republic, respectively. Hepatozoon ... -
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 ... -
