The relationship between initial Somatic Cell Count (SCC) and time to first clinical mastitis was estimated from data including 20,422 Holstein heifers, without clinical signs of mastitis during the first month of lactation and with a first test day SCC lower than 400,000 cells /ml. Number of days from 35 days after first calving to first clinical mastitis event in first or second lactation was...

Staphylococcus aureus is one of the main etiological agents of mastitis in different mammalian species. At present, it is unknown whether strains isolated from human mastitis cases share phenotypic properties and genetic background with those obtained from animal mastitis cases. Therefore, the objective of this study was to characterize S. aureus strains isolated from women with lactational mas...

ThirtyFrieswal lactating cows were screened for clinical and subclinical mastitis and subsequently classified into healthy, subclinically affected and clinically affected groups each group comprising of 10 cows. Polymorphism of cow lactoferrin (LTF) gene promoter was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The results showed that LFT gene pro...

In response to farmer requests after milk from their herds was rejected by processors due to poor quality, a study was carried out from April to October 2011 to determine the prevalence of sub clinical mastitis, associated risk factors and causative micro-organisms. Samples were collected from 195 dairy cows on 23 randomly selected dairy farms delivering milk to Isangano, Kirebe and Nyagatare m...

Annually, 10-33% of U.S. lactating women develop mastitis. Often underreported, mastitis has acute and chronic sequelae with rare documented cases of invasive breast surgery due to pervasive infection. Evidenced-based prevention, early recognition, and treatment of mastitis are not emphasized in the undergraduate nursing profession textbooks or academic settings. Using current evidence-based re...

: Factors relating to the occurrence of mastitis were studied on 12 Irish dairy herds with histories of elevated somatic cell count (SCC) and/or increased incidence of clinical mastitis cases. Milk recording data were analysed, housing conditions and calving areas were examined; dry cow therapy, clinical mastitis records, milking technique and aspects of milking machine function were assessed.H...

In dairy cattle, many farming practices have been associated with occurrence of mastitis but it is often difficult to disentangle the causal threads. Structural equation models may reduce the complexity of such situations. Here, we applied the method to examine the links between mastitis (subclinical and clinical) and risk factors such as herd demographics, housing conditions, feeding procedure...

The global dairy industry, the predominant pathogens causing mastitis, our understanding of mastitis pathogens and the host response to intramammary infection are changing rapidly. This paper aims to discuss changes in each of these aspects. Globalisation, energy demands, human population growth and climate change all affect the dairy industry. In many western countries, control programs for co...
