First lactation clinical mastitis records for Norwegian cattle from 1978 onwards were analysed. Variance components for clinical mastitis were estimated with a linear sire model using records of more than 500,000 daughters of 2043 sires. Heritability increased slightly as the period for sampling health data increased, and the longest period analysed (from 15 2 days before calving to 210 days af...

Bovine mastitis is very common in cows of both developed and developing countries. The prevalence of clinical and subclinical mastitis (SCM) varies from region to region. Hence, the present study was carried out to determine the prevalence of mastitis using three diagnostic tests by considering different risk factors like age, lactation, breed, season, quarters, and herd. The results showed tha...

Mastitis is a dairy farm disease which causes important loss for dairy industry. Mastitis control is permanent challenge for dairy farm [1]. Milk loss link to mastitis was assessed to reach 17% of world milk production [1]. In Burkina Faso, this loss is not assessed and remains unknown area. It is well known that the most spread mastitis is subclinical which has considerable impact on farm and ...

INTroDuCTIoN Mastitis is defined as any inflammatory process affecting the mammary gland (International Dairy Federation 1987). Clinical mastitis (CM) is defined as mastitis causing clinical signs in the udder or visible changes in the milk and according to the recommendation of the International Dairy Federation (IDF), is divided into severe, moderate or mild (International Dairy Federation 19...

Aim. To assess the temporal imaging evolution of granulomatous mastitis and to review imaging findings. Material and Methods. Retrospective review of imaging data of 10 patients with biopsy proven granulomatous mastitis. The patients were divided into 3 groups according to their initial imaging presentation. Temporal evolution of imaging findings was observed separately for each group. Ratios, ...

Difference in virulence between Staphylococcus aureus isolates causing gangrenous 2 mastitis versus subclinical mastitis in a dairy sheep flock 3 4 Eric VAUTOR Abstract – Staphylococcus aureus mastitis in dairy sheep ranges from subclinical mastitis to 22 lethal gangrenous mastitis. Neither the S. aureus virulence factors nor the host-factors or the 23 epidemiological events contributing to the...

The present study was designed to determine the quarter-wise comparative prevalence of mastitis in buffaloes and crossbred cows. Milk samples collected from 50 dairy buffaloes and 50 crossbred cows were tested for subclinical mastitis by Surf Field Mastitis Test. In addition, all milk samples were processed for isolation and identification of pathogens. In buffaloes, overall prevalence of subcl...

Mastitis is the most common and economically significant disease affecting dairy cattle. A variety of bacteria can be isolated from bovine mastitis cases. and are the most common causes of contagious and environmental clinical mastitis, respectively. Antimicrobial therapy is commonly implemented for mastitis prevention and control. Unfortunately, despite the best possible antimicrobial treatmen...

INTRODUCTION Among bacteria causing mastitis, only Streptococcus agalactiae, Staphylococcus aureus, Mycoplasma species, and Corynebacterium bovis are considered as fully contagious. Among these, S.aureus, is currently the most frequently isolated contagious pathogen in subclinical and chronic bovine mastitis worldwide (1). The reasons for the large spread of S.aureus intramammary infections (IM...
