application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. therefore, scientists are searching for alternatives to antibiotics nowadays. medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. in this paper, the benefits of...

The present study was conducted to find out the antibacterial activity of aqueous and organic extracts of Nigella sativa (L.) seeds against various bacterial pathogens, namely; S. aureus, P. aeruginosa and E. coli. Plant extract along with different elicitors such as metal ions and commercial drugs was also screened to see the change in efficacy and potency of the compounds. Among different ext...

Synthesis of silver nanoparticles using seeds of Nigella sativa as reducing agent was evaluated in this study. Homogenized extract of N. sativa exposed to sunlight gave a better synthesis of nanoparticles when compared to other methods. Antibacterial activity of nanoparticles was studied against urinary tract infection (UTI) causing bacteria by disc diffusion method. Further, the silver nanopar...

Nigella sativa (NS) has been shown to have antioxidant, anti-inflammatory and antiulcer activities in different conditions. The present work was done to investigate the possible effects of Nigella sativa aqueous extracts (NS) on gastric acid secretion in isolated rat stomach. Gastric acid secretion was measured in the isolated rat stomach preparation. The results obtained in vitro experiments s...

Background: New therapies for toxoplasmosis are critically needed. Nigella sativa, commonly known as black seed or black cumin, has been known to include many medicinal properties. It has anti-inflammatory, and immuno-potentiating effects, antihelminthic and antiprotozoal activities. Objective: To study the effect of black seed oil (BSO) from Nigella sativa against Toxoplasma gondii Me49 strain...

objective: nigella sativa (n. sativa) seeds were used in traditional medicine for the treatment of a variety of diseases. the seed extracts and oil of this plant have shown various pharmacological properties including antimicrobial actions. in this study, the in vitro and in vivo antibacterial effects of methanol extract of the seeds against pathogenic bacteria causing mastitis in cows have bee...

BACKGROUND Methicillin resistant Staphylococcus aureus (MRSA) continues to be one of the commonest pathogens encountered in clinical as well as laboratory practice. It has become a major health problem worldwide. Newer antimicrobials/agents are urgently needed to combat this problem MRSA resistance to various anti-staphylococcal agents. In the back-drop of this difficult situation Nigella sativ...
