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 ... -
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 ... -
Proliferation-apoptosis balance in Staphylococcus aureus chronically infected bovine mammary glands during involution
(2017-05)The objective of this study was to determine whether Staphylococcus aureus chronic intramammary infection (IMI) influences expression of proteins related to regulation of proliferation and apoptosis processes and ... -
Development and assessment of a new cage‐like particle adjuvant
(2017-10)Objectives: To obtain and assess stable cage‐like particles with low surface charge density, which can be prepared using a standardized, economic and scalable method. Methods: To form these nanoparticles, the lipid ... -
Susceptibilidad a antibióticos de Staphylococcus aureus aislados de mastitis bovina en lecherías de la cuenca central de Argentina
(2016-09)La mastitis bovina causa cuantiosas pérdidas económicas al productor lechero y la industria láctea a nivel mundial. Staphylococcus aureus es uno de los principales patógenos mayores causantes de infecciones intramamarias, ... -
Survey of potential factors involved in the low frequency of CP5 and CP8 expression in Staphylococcus aureus isolates from mastitis of dairy cattle from Argentina, Chile, and Uruguay
(2018-08)Staphylococcus aureus produces capsular polysaccharides (CPs) both in vivo and under defined culture conditions being serotypes 5 and 8 the most prevalent. S. aureus isolates that fail to produce CP5 or CP8 are defined as ... -
First detection of Hyalomma rufipes in Germany
(2016-10)Hyalomma rufipes, a two-host tick, is the most widespread Hyalomma species in Africa. In December 2015, an ixodid tick male with an unusual morphology was detected on a horse in a stable near Mainz in the Federal State ... -
