Breast abscesses can be a complication of infectious mastitis or the first presentation breast infection, presenting as pain, erythema, and lump. Actinomycosis is rare chronic disease caused by anaerobic branched filamentous gram-positive bacteria belonging to Actinomyces genus. It usually found in human mouth, digestive tract, genital tract but also cause abscesses. affecting condition that ty...

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 ...

In healthy milk the somatic cell count (SCC) is less than 100.000 cells per mL, although in presence of infectious agents, especially pathogenic bacteria, SCC can be extremely high. Cytological appearance inflammation mammary gland depends on origin and time-course inflammatory response. According to predominant type there suppurative, pyogranulomatous, granulomatous lymphocytic inflammation. P...

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...

Leptospirosis, an infectious disease of both animals and humans, is caused by infection with bacteria of the genus Leptospira. Leptospirosis in cattle may be manifested by different clinical syndromes such as a transient febrile response, a life threatening haemolytic crisis, chronic interstitial nephritis, mastitis, abortions, stillbirths and reproductive failure in cattle. Leptospirosis is an...

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...
