A new breeding value estimation procedure for mastitis traits has been implemented in the Dutch/Flemish dairy genetic evaluation. This breeding value estimation uses incidences of subclinical mastitis together with five indicator traits derived from test day somatic cell counts to predict the breeding value for resistance against subclinical and clinical mastitis (SCM and CM, resp.). The mastit...

antepartum mastitis is a rare condition, whereas postpartum or lactation mastitis is a common problem. this report introduces a case of complicated bilateral antepartum mastitis, which was treated successfully by drain insertion and antibiotic therapy. the patient was a 23-year-old woman in the 23 rd week of her first pregnancy. her chief complaint was progressive swelling, redness and radicula...

The effectiveness of combined staphylococcal vaccine (CSV), prepared from Staphylococcus aureus and coagulase negative staphylococci (CNS: Staphylococcus epidermidis, S. simulans, S. saprophyticus), on staphylococcal mastitis in sheep was determined. The group of pregnant sheep was vaccinated subcutaneously into supramammary lymph node twice at 3 week interval. Similarly, sterile saline was adm...

Mastitis continues to be a problem for dairymen across the US. Clinical mastitis causes economic loss due to treatment costs, lost quarters, perhaps dying cows and most importantly, discarded milk. Subclinical mastitis on the other hand, silently redu ces milk production and quality until detected with a somatic cell count. It is easy to forget the basics in our attempts to solve a mastitis pro...

Introduction Mastitis is the most frequent and costly disease of dairy cattle. Losses due to mastitis occur for both subclinical and clinical disease. Losses caused by clinical mastitis are often apparent and consist of discarded milk, transient reductions in milk yield and premature culling (Fetrow, 2000). Perceived financial losses for clinical mastitis vary widely. In 2002-2003, farmers part...

AIM A cross-sectional study was conducted to estimate the prevalence and associated risk factors of mastitis in dairy cows. MATERIALS AND METHODS A total of 302 dairy cows were selected from all volunteer dairy farms in Ambo district of West Shewa Zone, Oromia region. Thorough clinical examination was made on all lactating cows for evidence of signs of clinical mastitis followed by collection...

Dairy cow mastitis is an important disease in the dairy industry. Different microbial species have been identified as causative agents in mastitis, and are traditionally diagnosed by bacterial culture. The objective of this study was to use metagenomic pyrosequencing of bacterial 16S rRNA genes to investigate bacterial DNA diversity in milk samples of mastitic and healthy dairy cows and compare...

Amplicon sequencing technique has been increasingly applied to the clinical setting as a sensitive diagnostic tool. Therefore, it is of great importance to develop a DNA extraction method that accurate isolates DNA from complex host-associated microbiota. Given the multifactorial etiology of clinical mastitis and the diversified lifestyle of bacterial species harboring in milk, here four distin...
