Abstract

Staphylococcus aureus is a major pathogen causing intramammary infections (IMI) in dairy cattle herds worldwide. Simulation models can be used to investigate the epidemiologic and economic outcomes of different control strategies against IMI. The transmission rate parameter is one of the most...

Abstract

A longitudinal study was conducted to assess to what extent intramammary infection (IMI) with non-aureus staphylococci (NAS) within the first 4 d after calving in dairy heifers affects quarter milk yield (qMY) and quarter milk somatic cell count (qSCC) during the first 4 mo of lactation. In total,...

Abstract

Aim: To primarily estimate the sensitivity (Se) and specificity (Sp) of the commercially available Mastit4 quantitative PCR (qPCR) assay and bacterial culture (BC) for diagnosis of intramammary infections (IMI) and teat apex colonization (TAC) with coagulase-negative staphylococci (CNS) at...

Abstract

In the present study we describe an outbreak where PVL positive MRSA belonging to spa-type t002 and multi-locus sequence type ST2659 persisted in a Swedish dairy herd for at least two years, despite efforts to hinder transmission between animals and between the farmer and his animals. This is the...

Abstract

The aim of this cross-sectional study was to evaluate the prevalence of subclinical mastitis (SCM) and associated risk factors in dairy cows in peri-urban areas of Kigali, Rwanda, and identify causative udder pathogens. A sample of 256 cows from 25 herds was screened with the California Mastitis...

Abstract

In Switzerland, sanitation programs of dairy herds infected with the contagious mastitis pathogen Staphylococcus aureus genotype B (GTB) have been established for several years. In recent years, Streptococcus uberis and non-aureus staphylococci have emerged as the bacteria most frequently isolated...

Abstract

Bovine mastitis is the most frequent disease worldwide in dairy herds, causing high economic losses to producers and industry, as well as having implications for public health due to the zoonotic potential of some agents involved in its etiology and the increased risk of antimicrobial residues in...

Abstract

Staphylococcus hyicus and Staphylococcus agnetis are two coagulase-variable staphylococcal species that can be isolated from bovine milk and are difficult to differentiate. The objectives of this study were to characterize isolates of bovine milk origin from a collection that had previously been...
