thirtyfrieswal lactating cows were screened for clinical and subclinical mastitis and subsequently classified into healthy, subclinically affected and clinically affected groups each group comprising of 10 cows. polymorphism of cow lactoferrin (ltf) gene promoter was determined by polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp). the results showed that lft gene pro...

The aim of the present study was to compare the occurrence and duration of clinical mastitis in different seasons, stages of lactation period and parities in a Holstein dairy farm in Iran. A retrospective epidemiological survey from April 2005 to March 2008 was conducted on 884 clinical mastitis cases of 7437 lactations. Data of each case including calendar-date of mastitis onset, days in milk ...

A cross-sectional study to investigate prevalence, seasonal prevalence and causative agents of clinical and subclinical dromedary camel mastitis in Saudi Arabia (KSA) was conducted. The prevalence of acute mastitis was 3.6% and of chronic mastitis was 2.2%. Physical tests, California mastitis test (CMT) and somatic cell count (SCC), were done in normal and infected milk specimens to draw a bord...

Bovine mastitis, which is an inflammation of the mammary gland frequently resulting from bacterial infection, causes the majority of economic losses to the dairy producers. The prevalence of mastitis in dairy cattle is relatively high. Bovine mastitis can be classified based on clinical futures as clinical or subclinical. Both forms produce significant economic losses due to rejected milk, degr...

Coliform mastitis is tremendously important to the dairy industry for several reasons. First, it has become the predominant form of clinical mastitis and current management practices favor an increase in incidence. Second, coliform organisms cause some of the most severe cases of clinical mastitis. Third, as present trends in the dairy industry of increasing milk quality continue, environmental...

Mastitis is one of the most important diseases affecting production in dairy cattle. Control strategies against mastitis such as antibiotic therapy, vaccination, improvement of farm and feeding management have met with little success. Genetic variability of mastitis resistance is well established by several independent studies in different breeds of dairy cattle. Usage of somatic cell count or ...

Staphylococcus aureus is a major cause of mastitis in ruminants. In ewe mastitis, symptoms range from subclinical to gangrenous mastitis. S. aureus factors or host-factors contributing to the different outcomes are not completely elucidated. In this study, experimental mastitis was induced on primiparous ewes using two S. aureus strains, isolated from gangrenous (strain O11) or subclinical (str...

Escherichia coli, one of the main causative agents of bovine mastitis, is responsible for significant losses on dairy farms. In order to better understand the pathogenicity of E. coli mastitis, an accurate characterization of E. coli strains isolated from mastitis cases is required. By using phylogenetic analyses and whole genome comparison of 5 currently available mastitis E. coli genome seque...

Materials and Methods Mastitis is the inflammation of mammary gland; it is a complex disease which continues to have a major economic impact on the dairy industry throughout the world [1, 2]. The losses due to mastitis in USAalone are 1.7 billion dollars [3] while in India the losses are estimated to be about Rs. 7,165 crores [4]. The term mastitis comprises two relatively independent health pr...

Mastitis is one of the most prevalent production diseases affecting the dairy cattle industry worldwide. Its occurrence is associated with direct and indirect losses and expenditures. When estimating the cost of mastitis to the dairy industry the cost of the control programmes must be added. The direct losses of mastitis are the only costs obvious to the farmer. The difference between the costs...
