Diagnosing intramammary infections: Evaluation of composite milk samples to detect intramammary infections

Journal of Dairy Science, 2011
Composite milk samples, in which milk from all 4 bovine quarters is collected in a single vial, are widely used in many developed dairy industries for detection of intramammary infections (IMI). These samples are more economical for use in culturing protocols than individual quarter samples, and may be useful when considering management options at the ...

An update on environmental mastitis: challenging perceptions [PDF]

, 2017
Environmental mastitis is the most common and costly form of mastitis in modern dairy herds where contagious transmission of intramammary pathogens is controlled through implementation of standard mastitis prevention programmes.

Pilot study into milk haptoglobin as an indicator of udder health in heifers after calving [PDF]

, 2018
Mastitis, inflammation of the mammary gland, is often caused by intramammary infection with bacterial organisms. It impacts on dairy cattle welfare, production, udder health and longevity in the herd.

Innate Immune Response to Intramammary Mycoplasma bovis Infection [PDF]

Journal of Dairy Science, 2007
The objective of the current study was to characterize the systemic and local innate immune response of dairy cows to IMI with Mycoplasma bovis, a pathogen of growing concern to the dairy industry. Ten Holstein cows were each infused in 1 quarter with M. bovis and studied for a 10-d period.

Non-classical ProIL-1beta activation during mammary gland infection is pathogen-dependent but caspase-1 independent [PDF]

, 2014
Infection of the mammary gland with live bacteria elicits a pathogen-specific host inflammatory response. To study these host-pathogen interactions wild type mice, NF-kappaB reporter mice as well as caspase-1 and IL-1beta knockout mice were ...

Serum Amyloid A and Lactoferrin Concentrations in Milk at Mastitis Diagnosis Can Serve as a Predictive Indicators of Intramammary Status 7 Days Later. [PDF]

Anim Sci J
ABSTRACT This study investigated whether the inflammatory component levels in bovine milk measured on the day of mastitis diagnosis were associated with recovery outcomes 7 days later. Milk was collected on Day 0 (the initial day of mastitis diagnosis) and Day 7 from 40 quarters of 32 dairy cows diagnosed with spontaneous acute mastitis.

Deterministic model to evaluate the impact of lactational treatment of subclinical mastitis due to coagulase-negative staphylococci [PDF]

, 2011
Coagulase-negative staphylococci (CNS) are the most frequently isolated bacteria from milk samples in several studies worldwide. Despite their relative frequency, specific measures aiming at their control are not well established. One possible measure to

Treatment of an intramammary bacterial infection with 25-hydroxyvitamin D(3). [PDF]

PLoS ONE, 2011
Deficiency of serum levels of 25-hydroxyvitamin D(3) has been correlated with increased risk of infectious diseases such as tuberculosis and influenza. A plausible reason for this association is that expression of genes encoding important antimicrobial ...

Randomized noninferiority field trial evaluating a postmilking teat dip for the prevention of naturally occurring intramammary infections

Journal of Dairy Science, 2023
: The aim of this study was to perform a positive-controlled field study under natural exposure conditions to test the efficacy of a newly developed chlorine dioxide-based postmilking teat disinfectant (experimental product, EX) for noninferiority ...

Evaluation of minor pathogen intramammary infection, susceptibility parameters, and somatic cell counts on the development of new intramammary infections with major mastitis pathogens [PDF]

, 2012
Major mastitis pathogens such as Staphylococcus aureus, Streptococcus uberis, Streptococcus dysgalactiae, and coliforms are usually considered more virulent and damaging to the udder than minor mastitis pathogens such as Corynebacterium spp.
