vinca major, minor and rosea are three species of vinca genus and apocynaceae family. the present work is to investigate antimicrobial effects of these plants against candida albicans, pseudomonas aeroginosa and staphylococus aureus. alkaloids from leaf extracts had a better effect on pseudomonas aeroginosa than alkoloids from stem and root. alkaloids from stem extracts were more effective than...

Air dried flowers of Nerium oleander and Tecoma stans have been investigated for their polyphenolics. The pigments have been found to myricetin and rutin respectively which were characterized by chromatography and spectral studies. These pigments were screened for their antibacterial and antifungal activity against different organisms. It was ascertained that the ethyl acetate fractions of flow...

The role of coagulase in staplhylococcal infections is tincertain. It has been clemonstrated(1) that coagulase-negative hemolytic staphylococci wllen treated witlh coagulase and injected intracerebrally into mice exlhibit a higlher degree of virulence than the same organisms without treatment with coagulase. Other workers(2,3) have also found an association of coagtulase with virulence. However...

Culture filtrates of Lactobacillus lactis and Lactobacillus bulgaricus were observed to contain material inhibitory against Staphylococcus aureus. The concentration of inhibitor increased on storage of the lactobacilli at 5 C, and the maximum was attained af ter five days. A carbohydrate source was necessary for the formation of this inhibitory activity by resting cell suspensions. The inhibito...

Andrographis paniculata leaves on bacterial that cause diseases. And it was aimed to compare the effect of some selected bacteria with normal antibiotics. The isolates used in study were Staphylococcuc aurcus, Streptococcus pyogens, Proteus vulgaris and Escherichia coli. data collected by experimental method from laboratory as source primary data. Randomized complete block design two-way analys...

background coagulase-negative staphylococci (cons) are opportunistic pathogens. methicillin resistance is common in cons and may play an important role as reservoir of staphylococcal cassette chromosome mec (sccmec) for staphylococcus aureus. objectives the aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci am...

background protein a is the virulence factors of staphylococcus aureus rolling in its pathogenesis, and its gene is used for typing. polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) with different enzymes has been used for this action. objectives in this study, we used bsp143i enzyme for digestion of the gene, coding protein a (spa gene) in s. aureus. the bacteria w...
