Protection of the mammary gland against mastitis-causing pathogens is mediated by many factors in thegland and blood circulation. The professional phagocytic cells of bovine udder, polymorphonuclearneutrophils (PMN) and macrophages, comprise the first line of defense against invading mastitis pathogens.Most researchers now accept that the PMN is a key factor in the cows’ defense against intrama...

This manuscript presents the idea of providing dairy farmers with probability distributions to support decisions on mastitis management and illustrates its feasibility by two applications. Naive Bayesian networks were developed for both applications. The networks in the first application were used to compute probability distributions to support decisions on which cows from a mastitis alert list...

Mastitis is still one of the three main diseases that affects the profitability of dairy farmers. Despite the implementation of the five-point mastitis control programme in the early 1970 s, the incidence in the UK has not reduced dramatically over the past 10 years. A review of the scientific literature indicates that there is a link between nutrition and mastitis in the dairy cow. The major i...

Mastitis is inflammation of parenchyma of the mammary gland regardless of the causative agent. The objective of this study was to determine the prevalence, risk factors and financial losses caused by mastitis in six small holder dairy farms and the Animal Production and Research Center of the Wollega University. Data was collected through a questionaire on extrinsic and intrinsic risk factors a...

UNLABELLED Bovine mastitis is usually caused by either Gram positive or Gram negative bacteria, reducing the quantity and quality of milk produced. This investigation using capillary electrophoresis and mass spectroscopy, studied peptides in milk from cows with clinical mastitis in comparison to milk from healthy cows to identify biomarkers for mastitis. In addition, the milk peptidome from udd...

Mastitis is inflammation of mammary gland characterized by infiltration of leukocytes in udder tissue in response to various bacterial invasions. Staphylococcus aureus is the etiological agent more commonly associated to the disease and is normally related to both subclinical and chronic infections leading to severe economic loss to dairy farms. TLR4 is involved in the initiation of the immune ...

Non-aureus staphylococci (NAS) are most commonly isolated from subclinical mastitis. Different NAS species may, however, have diverse effects on the inflammatory response in the udder. We determined the genome sequences of 20 staphylococcal isolates from clinical or subclinical bovine mastitis, belonging to the NAS species Staphylococcus agnetis, S. chromogenes, and S. simulans, and focused on ...

The therapeutic potential of amoxicillin plus sulbactam and its effect on dynamics of milk leukocytes in bovine sub clinical mastitis were investigated in this study. Therapeutic efficacy was measured by somatic cell count and total bacterial count of the milk, whereas, the dynamics of milk leukocytes were assessed by measuring phagocytosis, hydrogen peroxide production, myeloperoxidase and lac...

Bovine milk samples were collected from cases of clinical and sub-clinical mastitis, respectively and examined bacteriologically and by simplex and multiplex PCR assays for detection of Staphylococcus aureus, Escherichia coli and Streptococcus agalactiae. Escherichia coli was the most common bacteria detected in the collected samples from clinical mastitis cases followed by Staphylococcus aureu...

Mastitis occurs in approximately 10 percent of U.S. mothers who are breastfeeding, and it can lead to the cessation of breastfeeding. The risk of mastitis can be reduced by frequent, complete emptying of the breast and by optimizing breastfeeding technique. Sore nipples can precipitate mastitis. The differential diagnosis of sore nipples includes mechanical irritation from a poor latch or infan...
