Mastitis is one of the causes diseases that can reduce livestock production. be caused by various types bacteria cause a decrease in production difficult to cure with antibiotics has been reported resistance. This study aims determine gram-negative mastitis cows. The used samples taken from folk farms means udder swabs. Bacterial isolation carried out planting Mannitol Salt Agar (MSA) media and...

Erythromycin was recovered in high yield after incubation with gram-negative bacteria. The cell-free protein-synthesizing preparation from gram-negative bacteria is equally as susceptible to the antibiotic as is that from gram-positive bacteria. Thus, neither destruction of erythromycin nor the absence of the step susceptible to the antibiotic plays an important role in the resistance mechanism...

Lipid-A, a complex glycolipid, is the highly immunoreactive endotoxic center of lipopolysaccharide (LPS). It anchors the LPS into the outer membrane of most gram-negative bacteria. Lipid A can be recognized by animal cells, triggers some defense-related responses, and causes gram-negative sepsis. The lipid-A biosynthesis pathway consists of nine enzymatic steps. The enzymes involved are: LpxA, ...

During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...

Background: Perovskia abrotanoides is small kind of lamiaceae family that find in iran and some neighboring countries by endemic. Objective: Because The effect of anti-bacterial and anti-fungal medical plant extract on bacteria and fungi and determine the Minimal Inhibitory Concentration (MIC) has not been done so present study follow the above aim. Methodes: In this study by using 80% methan...

Sclerorhachis platyrachis essential oil: Antioxidant power, total phenolic and flavonoid content its antimicrobial activity on some Gram-positive Gram-negative bacteria “in vitro”
