Abstractisolation_of_antimicrobial_producing_actinobacteria_from_soil_samples.pdf

Emergence of multidrug resistant bacteria has made the search for novel bioactive compounds from natural and unexplored habitats a necessity. have important bioactive substances. The present study investigated antimicrobial activity of isolated from soil samples of Egypt. One hundred samples were collected from agricultural farming soil of different governorates. Twelve isolates have produced activity against the tested microorganisms (, , , , , Typhi, , and ). By VITEK 2 system version: 07.01 the 12 isolates were identified as , , , and . Using ethyl acetate extraction method the isolates culture's supernatants were tested by diffusion method against indicator microorganisms. These results indicate that isolated from Egypt farms could be sources of antimicrobial bioactive substances.

BACKGROUND: Moringa peregrina is a wild plant that grown in the eastern desert mountains in Egypt. Although, this plant is native to Egypt, no details studies were traced on its chemical composition and biological activity.

MATERIALS AND METHODS: The different fractions of the ethanolic extract of the dried aerial parts of the plants were subjected to fractionation and purification on various silica and sephadex columns for the isolation of the major compounds which were tested for there anticancer activity. The aqueous and ethanolic extract as well as its different fractions were tested for antihyperglycemic effect on Streptozitocin-induced diabetes in rats.

RESULTS: Investigation of the different fractions of the ethanolic extract of the aerial parts of M. peregrina yielded lupeol acetate (1), β-amyrin (2), α-amyrin (3), β-sitosterol (4), β-sitosterol-3-O-glucoside (5), apigenin (6), rhamnetin (7), neochlorogenic acid (10), rhamnetin-3-O-rutinoside (12), and 6-methoxy-acacetin-8-C-β-glucoside (13) which were isolated for the first time from the plant. Compound (13) was isolated for the first time from genus Moringa. In addition, quercetin (8), chryseriol-7-O-rhamnoside (9) and quercetin-3-O-rutinoside (11) were also isolated. Identification has been established by spectral data (UV, MS, IR, 1H, 1H -1H COSY, and 13C-NMR). The major isolated compounds were found to have valuable cytotoxic activities against breast (MCF 7) and colon (HCT 116) cancer cell lines and their activities were comparable to the reference drug doxorubicin. On the other hand, the aqueous and ethanolic extracts as well as the n-hexane fraction were found to have potent antihyperglycemic effect on Streptozitocin-induced diabetes in rats.

CONCLUSION: The Egyptian plant M. peregrina is rich in biologically active ingredients which showed potent cytotoxic activity and also its ethanolic extraxt exert a significant antihyperglycemic effect.

Abdel-moein, K. A., and A. Samir, "Isolation of Enterotoxigenic Staphylococcus aureus from Pet Dogs and Cats: A Public Health Implication", Vector borne and Zoonotic Disease, 2011. Abstract

Staphylococcus aureus is a globally distributed bacterium causing wide variety of illnesses in humans, which attributed to its ability to produce wide array of virulence factors, including enterotoxins that are responsible for staphylococcal food poisoning outbreaks. The current study was carried out to investigate the prevalence of enterotoxigenic S. aureus among pet dogs and cats and its public health implication. For this purpose, nasal, oral, and wound swabs were collected from 70 dogs and 47 cats, whereas nasal swabs were collected from 26 human contacts.
