Staphylococcus aureus is a common Gram-positive pathogen that causes bovine mastitis, a persistent infection of the bovine mammary gland. Bovine mammary epithelial cells (BMEC) are important parenchymal cells of the bovine mammary gland. To better understand the importance of BMEC and the roles of the TLR-NF-κBand TLR-AP-1 signaling pathways in the regulation of S. aureus-associated mastitis and mammary fibrosis, BMEC cultured in vitro were stimulated with different concentrations of heat-inactivated S. aureus to analyze the gene and protein expression and production of toll-like receptor 2 (TLR2), toll-like receptor 4 (TLR4), transforming growth factor beta 1 (TGF-β1), basic fibroblast growth factor (bFGF) as well as the protein expression of nuclear factor-kappa B (NF-κB) and activation protein-1 (AP-1) by means of quantitative polymerase chain reaction (qPCR) and western blotting, respectively...

Milk loss due to increased somatic cell counts (SCC) results in economic losses for dairy producers. This research uses 10 mo of consecutive dairy herd improvement data from 2013 and 2014 to estimate milk yield loss using SCC as a proxy for clinical and subclinical mastitis. A fixed effects regression was used to examine factors that affected milk yield while controlling for herd-level management. Breed, milking frequency, days in milk, seasonality, SCC, cumulative months with SCC greater than 100,000 cells/mL, lactation, and herd size were variables included in the regression analysis...

The main objectives of this study were to quantify the consumption of antimicrobials on a convenience sample of dairy herds and to determine the association between herd-level antimicrobial consumption and inhibition zone diameters (IZD) of non-aureus staphylococci and Staphylococcus aureus isolates from subclinical mastitis cases. Also, the association between the IZD of non-aureus staphylococci and Staph. aureus isolates within a herd was studied. Antimicrobial consumption data on 56 Flemish dairy farms were obtained between 2013 and 2014 by so-called garbage can audits and expressed as antimicrobial treatment incidence (ATI), with the unit of ATI being the number of defined daily doses animal (DDDA) used per 1,000 cow-days...

Recently, it has been shown that the addition of meloxicam to standard antimicrobial therapy for clinical mastitis (CM) improves the conception rate of dairy cows contracting CM in the first 120 d in milk. The objective of our study was to assess whether this improved reproduction through additional treatment with meloxicam would result in a positive net economic benefit for the farmer. We developed a stochastic bio-economic simulation model, in which a dairy cow with CM in the first 120 d in milk was simulated...

Staphylococcus aureus is a frequent and major contagious mastitis bacterial pathogen. The antibiotic treatment cure rates vary considerably from 4% to 92%. Staphylococcus aureus readily becomes resistant to antibiotics, resulting in persistent noncurable intramammary infection that usually results in culling of infected animals. Because of its notorious ability to acquire resistance to the commonly used as well as last resort antimicrobials such as methicillin and vancomycin and the development of multidrug-resistant strains, antimicrobial resistance (AMR) in S...

Therapeutic and subtherapeutic use of veterinary drugs has increased the risk of residue contamination in animal food products. Antibiotics such as tetracycline are used for mastitis treatment of lactating cows. Milk expressed from treated cows before the withdrawal period has elapsed may contain tetracycline residue. This study developed a simple surface-enhanced Raman spectroscopic (SERS) method for on-site screening of tetracycline residue in milk and water. Six batches of silver colloid nanoparticles were prepared for surface enhancement measurement...

Idiopathic granulomatous lobular matitis (IGLM) is a rare non-specific inflammatory disease of the breast. Although IGLM is completely benign, it is easily confused with cancer due to progressive breast lump with firmly unilateral and discrete mass, nipple retraction and sinus formation. Patients with IGLM are usually associated with inflammation of the overlying skin. This study aimed to investigate the clinical characteristics of IGLM, treatment options and prognosis. From January 2010 to February 2015, 75 IGLM patients in our hospital were included, with an average age of 35...

Based on the widespread use of homeopathy in dairy farm practice when treating mastitis, a blind randomised controlled trial (RCT) was conducted to assess the effectiveness of homeopathic treatment of clinical mastitis on four dairy farms. The study considered specific guidelines for RCTs as well as the basic principles of individualised homeopathy and involved 180 lactating dairy cows. Evaluation of cure rates was based on clinical investigation of the udder and on laboratory analysis of milk samples. In culture-positive cases, the antibiotic treatment provided suboptimal bacteriological cures (60-81 per cent) but was more effective than individualised homeopathy (33-43 per cent) whose effects appeared little different to those of placebos (45-47 per cent) (P≤0...

Mastitis, which is generally described as an inflammation of breast tissue, is a common and debilitating disease which frequently results in the cessation of exclusive breastfeeding and affects up to 33% of lactating women. The condition is a primary cause of decreased milk production and results in organoleptic and nutritional alterations in milk quality. Recent studies employing culture-independent techniques, including metagenomic sequencing, have revealed a loss of bacterial diversity in the microbiome of mastitic milk samples compared to healthy milk samples...

Mammary pathology is infrequent during childhood. It is rare the probability of finding a breast mass in an infant. The most frequent possible diagnoses at this age are breast abscess, mastitis, breast engorgement due to maternal hormonal stimulation and hemangioma. Reaching the proper diagnosis is essential in order to apply a suitable treatment and avoid the potential disease complications. We present the case of a female infant having a mass in the right breast from birth. Initially the entity was treated as mastitis...

Quercetin is a dietary flavonoid which has an effect on inflammation, angiogenesis and vascular inflammation. In several other flavonoids (e.g. kaempferol, astragalin, alpinetin, baicalein, indirubin), anti-inflammatory mechanism was proven by using mice mastitis model. The aim of the current study was pilot analysis of quercetin tolerability and its impact on somatic cells count (SCC) after multiple intramammary treatment on dairy cows with clinical mastitis. Based on SCC and clinical investigation, 9 dairy cows with clinical mastitis of one quarter were selected for the pilot study...

Mastitis is a disease of major economic importance to the dairy cattle sector because of the high incidence of clinical mastitis and prevalence of subclinical mastitis and, consequently, the costs associated with treatment, production losses, and reduced animal welfare. Disease-recording systems compiling data from a large number of farms are still not widely implemented around the world; thus, selection for mastitis resistance is often based on genetically correlated indicator traits such as somatic cell count (SCC), udder depth, and fore udder attachment...

Peptidoglycan hydrolases (PGHs) have been suggested as novel therapeutics for the treatment of bovine mastitis. However, activity in the presence of cow's milk is an important requirement for drugs administered into the bovine udder. We have used a microtiter plate-based protocol to screen a library of >170 recombinant PGHs, including engineered bacteriophage endolysins, for enzymes with activity against Staphylococcus aureus in milk. Eight suitable PGH constructs were identified by this approach, and their efficacies against S...

BACKGROUND Brugada pattern on electrocardiogram (ECG) is seen when there are at least 2 mm J-point elevation and 1 mm ST-segment elevation in two or more of the right precordial leads, with right bundle-branch block (RBBB)-like morphology. Elevation of a coved-type shape in leads V1 and V2 is consistent with type I Brugada pattern, whereas elevation of a saddle-back configuration distinguishes type II Brugada. If accompanied by life-threatening arrhythmias or sudden cardiac death, Brugada syndrome (BrS) is diagnosed...

Breast inflammation can signal an array of breast conditions, from difficulties with breastfeeding to a rare and aggressive type of breast cancer. In some cases, these diseases resemble each other clinically and on imaging examinations. This article explains the inflammatory process and discusses a variety of localized benign inflammatory breast diseases, including lactational and nonlactational mastitis, ductal ectasia, idiopathic granulomatous mastitis, fat necrosis, and diabetic mastopathy. Inflammatory breast cancer also is presented, with an emphasis on its signs and symptoms, diagnosis, staging, multimodality treatment, and prognosis...
