BACKGROUND & PURPOSE Antibiotic resistance rate is increasing in Acinetobacter species, especially in Acinetobacter baumannii, as the most important pathogen of hospital and ICU . This research aimed to evaluate antibiotic resistant rate of Acinetobacter spp. isolated from patients admitted to ICUs in educational hospitals affiliated with Mazandaran University of Medical Sciences. METHODS In ...

background: calf diarrhea is an important disease that is caused by different pathogens including bacteria, virus and parasites and is associated with economic losses. objectives: in this study, we evaluated the antibacterial activities of zatacin (z. multiflora aerial part ethanol extract), colistin, co-trimoxazole and enrofloxacin against clinical isolates of salmonella sp, e. coli and campyl...

Food-borne diseases have always been a major concern to the consumers, food safety authorities and food industries. Hylocereus spp or Pitaya peels are normally treated as wastes and will be discarded during processing. In this study, the antibacterial activity of ethanol, chloroform and hexane extracts from Hylocereus polyrhizus (red flesh pitaya) and Hylocereus undatus (white flesh pitaya) pee...

The antibacterial activity of leaf juice and extracts of Moringa oleifera Lam., belonging to the family Moringaceae, was determined in vitro, using disc diffusion and minimum inhibitory concentration (MIC) determination method against human pathogenic bacteria. The fresh leaf juice (10 μl disc-1), powder from fresh leaf juice, cold water extract of fresh leaf, each of 1175 μg disc-1, displayed ...

AIM: The present study aims to investigate for the first time antitumor and antibacterial activities of Viscum album L. grown on different host trees. METHODS: Two different bioassays (antitumor and antibacterial) were performed to evaluate the biological activities of European mistletoe (Viscum album L.) plants collected from 13 different host trees (Crataegus tanacetifolia, Crataegus monogyna...

Hexane, chloroform, methanol, chloroform: methanol (2:1 v/v) and petroleum ether extracts of Turbinaria conoides from the coast of Mandapam were tested in vitro for their antibacterial activities against Escherichia coli, Salmonella typhi, Staphylococcus aureus, Pseudomonas aeruginosa and Proteus mirabilis with the disc diffusion method. Petroleum ether was the best solution for extracting the ...

In an effort to document the antibacterial properties of plants commonly used by the people of Puerto Rico, we studied the effects of 172 plant species, utilizing the disc diffusion method, against Escherichia coli and Staphylococcus aureus. The methanolic extracts of 14 species showed antibacterial activities during this preliminary screen. These positive plant extracts were tested successivel...

The study describes the antibacterial and anticancer activities of a nanocomposite prepared by mixing zinc oxide and titanium dioxide nanoparticles. The particle mixtures were analyzed by X-ray diffraction, Field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and dynamic light scattering techniques. Thus, analyzed samples were s...

The aqueous extract of Phyllanthus amarus Schum & Thorn, was selected for preliminary phytochemical and antibacterial activity against human pathogens. Minimum inhibitory concentration was performed by broth dilution method and the zone of inhibition was studied by agar disc diffusion method at concentrations of 10 and 20 mg/ml in DMSO (Dimethyl Sulfoxide). The results revealed the antimicrobia...

The present study was conducted to determine the antibacterial activity of Tribulus terrestris against Pseudomonas aeruginosa. Four different concentrations i.e. 15mg/ml, 20mg/ml, 25mg/ml, 30mg/ml of different extract of water and ethanol extracts of Tribulus terrestris were screened for antibacterial activity by disc diffusion method. Ofloxacin was control drug. Ethanol extract of Tribulus ter...
