The study aimed to investigate the phenotypic and genotypic identification of in vitro antimicrobial susceptibility of 21 Staphylococci (10 Staphylococcus aureus and 11 Coagulase Negative Staphylococci) isolated from bovine mastitis to 12 antimicrobial drugs frequently using in veterinary medicine in Algeria. Isolates of staphylococci from bovine mastitis were tested for antibiotics with disc-d...

background: bovine mastitis is the most costly disease in dairy cows and causes significant decrease in milk production. this disease is one of the main reasons of antibiotic therapy in dairy cows. objectives: staphylococcus aureus is counted as a major pathogen associated with the outbreaks of mastitis in dairy herds. therefore, the purpose of the present study is to examine the antibacterial ...

Treatments for bovine mastitis based on antibiotic therapy are not always effective which may lead to faults in recovery of diseased animals, selection of resistant bacteria and the presence of antimicrobial residues in milk. In this context the use of essential oils configures as an alternative to control mastitis pathogens in dairy cows because they have antibacterial action against gram-posi...

AIM An attempt has been made to study the toll-like receptors 4 (TLR4) gene polymorphism from cattle DNA to correlate with mastitis cows. MATERIALS AND METHODS In present investigation, two fragments of TLR4 gene named T4CRBR1 and T4CRBR2 of a 316 bp and 382 bp were amplified by polymerase chain reaction (PCR), respectively from Kankrej (22) and Triple cross (24) cattle. The genetic polymorph...

The respiratory burst activity of neutrophil leukocytes from bovine peripheral blood was studied before and during an experimentally induced Escherichia coli mastitis. The competence of neutrophils to generate reactive oxygen species following stimulation with opsonized particles prior to infection was negatively correlated with severity of subsequently induced E. coli mastitis. In the presence...

PURPOSE This study was conducted in order to determine the occurrence of esp and biofilm formation among Enterococcus faecalis causing mastitis isolated from different bovine and environmental origins. MATERIALS AND METHODS A total of 41 E. faecalis isolates were obtained from clinical mastitis before antibiotic therapy, subclinical mastitis, dried manure bedding samples, and postpartum milk ...

Mastitis is one of the most prevalent and costly diseases in the dairy industry with losses attributable to reduced milk production, discarded milk, early culling, veterinary services, and labor costs. Typically, mastitis is an inflammation of the mammary gland most often, but not limited to, bacterial infection, and is characterized by the movement of leukocytes and serum proteins from the blo...

Blood samples were collected from healthy and mastitic cattle and buffaloes. Platelet Count, Prothrombin time, Activated Partial Thromboplastin Time and Fibrinogen Degraddation Products were estimated. There was no signi cant difference between healthy and affected animals.

Bovine subclinical mastitis is an inflammation of the mammary gland caused by bacterial intramammary infection, accounting for large economic losses. Treatment of subclinical mastitis is not suggested for lactating cows due to the risk of milk contamination. The objectives of this study were to evaluate an antimicrobial peptide, nisin, in the treatment of subclinical mastitis in lactating cows....

Polymorphonuclear neutrophil (PMN) leukocytes are primary phagocytic cells of the bovine mammary gland and a first line of defense against invading pathogens during bovine mastitis infection. Cluster of differentiation 14 (CD14) is mainly expressed in macrophages and neutrophils and acts as a co-receptor that binds bacterial lipopolysaccharide (LPS) and recruits PMNs to CD14-LPS complexes in ma...
