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 ...

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...

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...

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...

Staphylococcus aureus is a major causative agent of mastitis in dairy cows. The pathogenicity of S. aureus may vary; it is able to cause severe clinical mastitis, but most often it is associated with chronic subclinical mastitis. Here, we present the genome assemblies of four S. aureus strains from bovine mastitis.

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...

BACKGROUND Mycoplasma mastitis is increasingly posing significant impact on dairy industry. Although the effects of major conventional mastitis pathogens on milk components has been widely addressed in the literature, limited data on the effects of different Mycoplasma and Acholeplasma spp. on milk quality and quantity is available. The aim of this study was to determine the casual relationship...
