New records and host associations of the tick Ixodes apronophorus and the first detection of Ehrlichia sp. HF in Romania
(2018-04)Ixodes (Ixodes) apronophorus is a neglected tick species and its geographical distribution, host associations, and role as a disease vector are not well known. We collected I. apronophorus from several locations in Romania. ... -
The association between mastitis and reproductive performance in seasonally-calved dairy cows managed on a pasture-based system = Asociación entre la mastitis y el desempeño reproductivo en rodeos lecheros Holstein de base pastoril y servicios estacionados
(2014)The objective of this study was to assess association between clinical, subclinical mastitis, body condition score and the reproductive performance of cows under seasonally calving conditions in a pasture-based management ... -
Immune response of heifers against a Staphylococcus aureus CP5 whole cell vaccine formulated with ISCOMATRIX™ adjuvant
(2013-02)The shortcomings of Staphylococcus aureus vaccines to control bovine mastitis have been attributed to insufficient capacity of the vaccines to induce opsonizing antibodies and to stimulate cellular immune responses. Types ... -
Staphylococcus aureus chronic intramammary infection modifies protein expression of transforming growth factor beta (TGF-β) subfamily components during active involution
(2014-02)The objectives of this study were to determine whether Staphylococcus aureus chronic intramammary infection (IMI) influences protein expression of TGF-β subfamily components and collagen I and to examine the histomorphometric ... -
Immune response of heifers against a Staphylococcus aureus CP5 whole cell and lysate vaccine formulated with ISCOM Matrix adjuvant
(2014-02)Staphylococcus aureus is the most frequently isolated pathogen from bovine intramammary infections worldwide. Commercially available vaccines for mastitis control are composed either of S. aureus lysates or whole-cells ... -
Functional role of antibodies generated in heifers through immunization with Staphylococcus aureus vaccines in invasion and phagocytosis assays
(2014-11)A successful Staphylococcus aureus vaccine should elicit a long-term antibody response that prevents establishment of the infection. The aim of the present study was to evaluate the functional role of antibodies raised ... -
Immune response and functional role of antibodies raised in heifers against a Staphylococcus aureus CP5 lysate and recombinant antigens vaccine formulated with Iscom Matrix adjuvant
(2014-12-15)Staphylococcus aureus is the most frequently isolated pathogen from bovine intramammary infections worldwide. Commercially available vaccines for mastitis control are composed either of S. aureus lysates or inactivated ... -
Which are important targets in development of S. aureus mastitis vaccine?
(2015-06)Staphylococcus aureus represents one of the leading causes of mastitis in dairy cows worldwide. S. aureus IMI have variable outcomes due to virulence of the strain involved, immune defenses of the host, and by antibiotic ... -
Single nucleotide polymorphisms in candidate genes and their relation with somatic cell scores in Argentinean dairy cattle
(2015-11)The prevention and control of bovine mastitis by enhancing natural defenses in animals is important to improve the quality of dairy products. Mastitis resistance is a complex trait which depends on genetic components, as ... -
Preparation and characterization of a Staphylococcus aureus capsular polysaccharide-protein conjugate prepared by a low cost technique: a proof-of-concept study
(2015-01)Staphylococcus aureus is a worldwide distributed pathogen that produces several diseases in many species and is the major cause of mastitis in dairy cows. S. aureus capsular polysaccharide 5 (CP5) has been widely proposed ... -
Genotyping and study of the pauA and sua genes of Streptococcus uberis isolates from bovine mastitis = Genotipificación y estudio de los genes pauA y sua de aislamientos de Streptococcus uberis de mastitis bovina
(2015-12)This study aimed to determine the clonal relationship among 137 Streptococcus uberis isolates from bovine milk with subclinical or clinical mastitis in Argentina and to assess the prevalence and conservation of pauA and ... -
A new sunflower high oleic mutation confers stable oil grain fatty acid composition across environments
(2016)The oil industry demands sunflower oils with high oleic acid content. New varieties producing high oleicoils independently of the growing environment are needed as growers could receive an extra prime foroffering them. Oil ... -
Genome-wide association study for somatic cell score in Argentinean dairy cattle
(2015-05)This study aimed to understand the genomic architecture of Argentinean dairy herds by measuring linkage disequilibrium (LD) and identifying loci associated with parameters calculated from somatic cell count (SCC). Phenotypic ... -
Comparison of phenotypic tests for detecting penicillin G resistance with presence of blaZ gene in Staphylococcus aureus isolated from bovine intramammary infections
(2015-08)Few studies have described the relationship between genotypic and phenotypic methods for detecting penicillin resistance in Staphylococcus aureus isolated from bovine intramammary infection (IMI). Six phenotypic methods ... -
