BACKGROUND The incidence of bacteremia caused by Gram-negative bacteria has increased recently in febrile neutropenic patients with the increase of antibiotic-resistant Gram-negative bacterial infections. This study aimed to identify the distribution of causative bacteria and the proportion of antibiotic-resistant bacteria in bacteremia diagnosed in febrile neutropenic children. MATERIALS AND...

Medicinal plants are in rich source of antimicrobial agents. The present study was carried out to evaluate the antibacterial and antifungal effect of five important plants namely, Andrographis paniculata, Bacopa monnieri, Centella asiatica, Nardostachys jatamansi ,Saraca indica. The preliminary phytochemical analysis was tested by using different extract of these plants for the presence of vari...

Scientific investigations of medicinal plants have been initiated in many parts our country because their contribution to health care. The properties are due the presence phytochemicals. phytochemicals anti-oxidant and anti-microbial properties. resistance antibiotics by bacteria is increasingly becoming a concern public health. Currently used antibiotic agents fail bring an end bacterial infec...

several heavy metal resistant bacterial strains were isolated from sediment and water samples collected from the persian gulf and enclosed industrial areas. all the isolated bacteria were identified by 16s rrna gene sequencing. isolated bacteria were tested for the presence of plasmids using the modified alkaline lysate method. the method was effective for identification and characterization of...

Nowadays the most difficult problem in treatment of bacterial infections is the appearance of resistant bacteria to the antimicrobial agents so that the attention is being drawn to other potential targets. In view of the positive findings of phage therapy, many advantages have been mentioned which utilizes phage therapy over chemotherapy and it seems to be a promising agent to replace the antib...

BACKGROUND AND OBJECTIVES Multidrug-resistant gram-negative bacteria are rapidly spreading throughout the world. The epidemiology of multidrug-resistant gram-negative bacteria in patients who require chronic hemodialysis has not been previously studied. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A prospective cohort study of an outpatient hemodialysis unit was conducted. Serial surveillanc...

cladophora and enteromorpha are the filamentous green-algal genuses that have a widespread distribution in caspian sea coast. the aim of this study was to assess the antimicrobial activities of cladophora and enteromorpha in south of caspian sea. antibacterial activities of hydroalcoholic extracts of five different gram negative and positive bacteria including staphylococcus aureus, bacillus su...

The present paper deals with the structure, occurrence and biological activity of ellagitannins. Ellagitannins belong to the class of hydrolysable tannins, they are esters of hexahydroxydiphenoic acid and monosaccharide (most commonly glucose). Ellagitannins are slowly hydrolysed in the digestive tract, releasing the ellagic acid molecule. Their chemical structure determines physical and chemic...

Infectious disease is one of the diseases caused by microbes, including bacteria. Staphylococcus epidermidis and Escherichia coli are gram-positive gram-negative bacteria that cause infectious diseases. The selection medicinal plants as an alternative solution effective way reducing resistance Based on empirical data, herbal with antimicrobial potential red ginger (Zingiber officinale var rubru...

Diarrhea is a disease that causes sufferers to have frequent bowel movements with watery or stools. One of the diarrhea Escherichia coli bacteria. plants has been used as an antidiarrheal guava (Psidium guajava L.), especially leaves. Guava leaves are known contain phytochemicals, namely: tannins, flavonoids, alkaloids, saponins, and essential oils which function antibacterials. This study aims...
