Clinical mastitis (CM) and lactation mean somatic cell score (LSCS) were analyzed with a bivariate linear sire model. Nearly 1.4 million primiparous cows of Norwegian Dairy Cattle from 2043 sires were used. The heritability estimates were 0.03 for CM and 0.11 for LSCS. The estimates of genetic and residual correlations between the 2 traits were 0.53 and 0.10, respectively. It is postulated that the genetic correlation probably is highly population-specific.

Although idiopathic granulomatous mastitis (GM) of the breast is a benign condition, it can be locally aggressive and frequently chronic, causing significant pain and distress to the patient. Treatment often involves multiple disciplines including general practice, breast surgery/physicians, rheumatology and/or immunology. Traditional options for treatment include observation, oral steroids, methotrexate and/or surgery, all with variable outcomes.

A cross-sectional study on 156 smallholder dairy farms in Rwanda was carried out to assess the association between farm management practices and milk yield and quality. A pre-tested questionnaire was used to collect data on cow characteristics and farm management practices. Milk yield was recorded at household level, milk composition was monitored using a Lactoscan device (Milk Analyzer).

Early detection of bovine mastitis-causing pathogens is necessary for treatment. As culturing methods are time-consuming, a more rapid detection technique is required. This study investigated the sensitivity, specificity, and detection limit of Gram staining of milk precipitates (milk Gram stain, MGS) to detect bovine mastitis-causing pathogens in milk, as well as the potential of MGS to diagnose inflammation by counting polymorphonuclear leukocytes (PMN).

Purpose: To differentiate inflammatory breast cancer (IBC) from mastitis in Asian women presenting with symptoms of inflammation.
Methods: Between January 2012 and June 2024, 101 Asian women with symptoms of inflammation underwent breast ultrasound (US). Clinical and demographic data were extracted from patients' medical records.
