Unfavorable conditions can affect on secondary metabolites production in the plants. The aim of present study was to evaluate the effect of heavy metals accumulation on antibacterial potential of Chenopodium murale L., Senecio glaucus L., Malva parviflora L. and Calendula arvensis L. grown in an industrial area of steel production in Ahvaz, southwest of Iran. The cadmium (Cd), iron (Fe), mangan...

Lyme disease is the most common zoonotic bacterial disease in North America. It is estimated that >300,000 cases per annum are reported in USA alone. A total of 10%-20% of patients who have been treated with antibiotic therapy report the recrudescence of symptoms, such as muscle and joint pain, psychosocial and cognitive difficulties, and generalized fatigue. This condition is referred to as po...

objectives this study explored the qualitative and quantitative antibacterial potential of c. intybus. further qualitative analysis of phytochemical content was performed. methods cichorium intybus seed extracts were prepared in aqueous, chloroform, ethanol, and hexane separately. results all the extracts of c. intybus seeds were screened for antibacterial activity and phytochemical content. ci...

background bedsore is one of the major problems in all the societies as patients are confined to bed. due to antibiotic resistant strains being a significant obstacle for cure, many plants and herbs are being used by researchers as medicinal compounds. objectives the investigation of synergistic effect of cellulose biopolymer and papaver macrostomum extract on bedsores bacterial community. mate...

In the present investigation, a series of 12 Mannich bases (QP1-12) and 5 Schiff bases (QSP1-5) of pyrazol-5(4H)-one moiety containing 3-(hydrazinyl)-2-phenylquinazolin-4(3H)-one has been synthesized and characterized by physicochemical as well as spectral means. The synthesized Mannich and Schiff bases were screened for their preliminary antimicrobial activity against Gram-positive and Gram-ne...

The most common bacterial diseases in pond-raised channel cat¢sh Ictalurus punctatus (Ra¢nesque) are enteric septicemia of cat¢sh and columnaris, caused by Edwardsiella ictaluri and Flavobacterium columnare respectively. Medicated feed containing antibiotics is one management approach that cat¢sh producers use in the treatment of bacterial diseases. However, the future use of all types of medic...

Objective Halitosis can be caused by microorganisms that produce volatile sulphur compounds (VSCs), which colonize the surface of the tongue and subgingival sites. Studies have reported that the use of natural products can reduce the bacterial load and, consequently, the development of halitosis. The aim of this study was to evaluate the antimicrobial activity of the essential oil of Melaleuca ...

bacterial resistance to antibiotics is a serious problem and is increasing in prevalence world-wide at an alarming rate. the antimicrobial susceptibility patterns of 1897 gram-positive bacterial isolates were evaluated. the minimum inhibitory concentration (mic) of isolates which comprised staphylococcus aureus (927 isolates), coagulase-negative staphylococci (cns; 425 isolates), enterococcus f...

background and purpose: candidiasis is a major fungal infection, and candida albicans is the major cause of infections in humans. the clinical and laboratory standards institute (clsi) developed new breakpoints for antifungal agents against c. albicans. in this multi-center study, we aimed to determine the drug susceptibility profile of c. albicans, isolated from iranian population according to...
