conclusions silver nanoparticles have high therapeutic activity against mrsa, thus can be suggested as an alternative or adjuvant with antibiotics for mrsa treatment. further studies are required to understand the synergistic effect of ag-nps combinations and to assess the safety and efficacy of new antibiotic-ag-nps combinations. background methicillin-resistant staphylococcus aureus (mrsa) ar...

there is a long period between harvested beets and their transfer to the sugar factory. sugar beet crop is damaged and injured during harvest and transport which provides a suitable place for various saccharoliytic microorganisms growth in terms of temperature, moisture, ph and glucose concentration. in this study, samples were randomly selected from the roots stored in spring 2010 and also the...

Neem (Azadirachta indica) is a multifunction plant. Its leaves and seeds can be used as a traditional medicine. One of the benefits of neem seeds is that they can serve as antibacteria. It happens because neem seeds contain certain substances which can impede the growth of Salmonella thyposa and Staphylococcus aureus bacteria. The aims of this research were to find out the efectiveness of soaki...

In the environment, multiple microorganisms coexist as communities, competing for resources and often associated as biofilms. In this study, single- and dual-species biofilm formation by, and specific activities of, six heterotrophic intergeneric bacteria were determined using 96-well polystyrene plates over a 72-h period. These bacteria were isolated from drinking water and identified by parti...

The use of natural products in compounded wound care formulas is an exciting avenue to pursue for compounding pharmacists since these natural products may contain compounds that promote healing on their own. The use of these natural extracts as an alternative therapy for wound care may also provide several benefits, such as decreased inflammation, infection, side effects, and treatment costs. T...

to determine the prevalence of bacterial mastitis in cattle, milk samples positive for california mastitistest (cmt) were cultured during a period of almost 4 years. the bacterial species isolated from 2904 milksamples studied were coagulase negative staphylococcus sp. in 879 (30.27%) samples, streptococcusagalactiae in 642 (22.11%), s. dysgalactiae in 332 (11.43%), e. coli in 295 (10.16%), sta...

Leukotoxin-producing Mannheimia haemolytica consistently causes fatal pneumonia in bighorn sheep (BHS) under experimental conditions. Surprisingly, by culture methods, it has been isolated from pneumonic BHS lungs less frequently than other bacteria. However, in one study PCR assays detected M. haemolytica from over 70% of the pneumonic lung samples that were negative for this organism by cultu...

The in vitro antibacterial activity of various solvents and water extracts of aloe vera, neem, bryophyllum, lemongrass, tulsi, oregano, rosemary and thyme was assessed on 10 multi-drug resistant clinical isolates from both Gram-positive and Gram-negative bacteria and two standard strains including Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922. The zone of inhibition as determ...
