mastitis, inflammatory disease of mammary glands, can be caused by various microorganisms. many antimicrobial agents have been evaluated to combat the causative agents. development of resistance in pathogens against conventional antibiotics may be high; hence at present study in vitro efficacy of a new fluoroquinolone antibiotic (marbofloxacin) against isolated pathogens from clinical mastitis ...

The present work was designed to evaluate the in vitro lipid peroxidation inhibitory and antimicrobial activities of the methanol extract of Phyllanthus niruri (MEPN) (Family:   Euphorbiaceae) .   Lipid peroxidation was measured by the optical density of the prepared solutions (10-320 µg/ml) and then the percent inhibition was calculated. Ascorbate/FeSO 4 -induced p...

In the present study, the therapeutic potential of bacteriophages virulent to Staphylococcus aureus associated with goat mastitis were isolated, identified and assessed. Staphylococcus aureus (host or indicator bacterium) was isolated from a goat suffering from clinical mastitis. Based on cultural, morphological, biochemical tests and amplification of S. aureus specific thermonuclease gene inPC...

Background: Recently the role of platelets in the tissue regeneration, wound healing and prevention and control of infections has been reported. We aimed to assess the antimicrobial effect of human platelet concentrate against six bacteria, commonly found in wound and hospital-acquired infections. Methods: In vitro susceptibility to samples of 10 random human platelet concentrates was determin...

Food preservation is an action or a method of maintaining foods at a desired level of properties or nature for their maximum benefits. In general, each step of handling, processing, storage, and distribution affects the characteristics of food, which may be desirable or undesirable. Thus, understanding the effects of each preservation method and handling procedure on foods is critical in food p...

in this study, extracts and essential oils of black and red pepper and thyme were tested for antibacterial activity against escherichia coli o157:h7 andstaphylococcus aureus. black and red pepper and thyme were provided from iranian agricultural researches center. 2 g of each plant powder was added to 10 cc ethanol 96°. after 24 h, the crude extract was separated as an alcoholic extract and con...
