Objective: Tribes in Nubia Mountains regions of Sudan used Monechma ciliatum seeds for common cold and other chest allergic conditions as a traditional medicine. The aim of this paper is to validate this traditional practice scientifically. Materials and Methods: Monechma ciliatum seeds were screened for major phytochemical groups using standard methods. Different extracts were bioassayed in- v...

regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. the current study was performed to determine antimicrobial potenti...

We established a novel screening method to identify antibacterial compounds and used the screen various triterpenoids, which are difficult assay using existing methods. The involves comparison of shape bacterial growth curves based on changes in culture turbidity. Growth were grouped multiple classification analysis. tested belonged different chemical group than controls. Six four triterpenoids...

Knowledge of the synergic properties of staphylococcus toxin is comparatively recent: in 1933 Dr. E. L. Burky observed in rabbits immunized with staphylococcus toxin a reaction to the broth in which the toxin had been produced. In explanation he suggested that the "growth activities of the staphylococci had separated from the medium some substance which, when attached to the toxin, became antig...

The transition of the bacterial biota Kishu saba-narezushi (mackerel-narezushi) in Hidaka region Wakayama prefecture, Japan, was analyzed using amplicon sequencing based on V3–V4 variable 16S rRNA gene. In non-fermented sample (0 day), major genus with highest abundance ratio Staphylococcus. early stage (fermentation for 2 days), however, Lactococcus became a dominant species, and later 5 Lacto...

A model system mimicking Staphylococcus aureus bacteremia was developed by growth in serum under microaerobic conditions. Eight genes induced by growth in serum were identified, including an antimicrobial peptide biosynthesis locus, amino acid biosynthetic loci, and genes encoding putative surface proteins. Nine independent insertions were found in the major lysine biosynthesis operon, which en...

Growth of methicillin-susceptible and -resistant strains of Staphylococcus aureus at 28 and 37 degrees C led to changes in the relative amounts of phospholipids recovered. The major phospholipids present in these strains were phosphatidylglycerol, lysophosphatidylglycerol, and diphosphatidylglycerol. Phosphatidylglycerol tended to occur in lower amounts in the resistant strains, but it was the ...

Iron deficiency is the most common nutrient deficiency worldwide and routine supplementation is standard policy for pregnant mothers and children in most low-income countries. However, iron lies at the center of host-pathogen competition for nutritional resources and recent trials of iron administration in African and Asian children have resulted in significant excesses of serious adverse event...

Rapid culture of Mycobacterium avium subspecies paratuberculosis (MAP) from patients remains a challenge. During the process of developing a rapid culture method for MAP, we found that there is an alternative growth behavior present in MAP, MAH (Mycobacterium avium subspecies hominissuis) and other bacteria such as Staphylococcus aureus, and Staphylococcus pseudintermedius. The bacterial DNA, R...

conclusions basidomes collected from four locations in thailand had low genetic variation and their extracts inhibited the growth of all tested bacteria. the health benefits of this edible species should be evaluated further. background boletus griseipurpureus corner, an edible mushroom, is a putative ectomycorrhizal fungus. currently, the taxonomic boundary of this mushroom is unclear and its ...
