Introduction: Bacterial pneumonia occurs in most hospitalized patients where is the important cause of morbidity and mortality. To reduce the mortality rate, we aimed to isolate the bacterial agents of pneumonia and determine the antibacterial resistance. Methods: In this descriptive study, 330 hospitalized patients inffered from bacterial pneumonia were studied to identify the bacterial ag...
Hexane, petroleum ether, chloroform, ethyl acetate, acetone and methanol extracts of Tulsi (Ocimum sanctum) were analyzed for determination antibacterial activity against enteric-pathogenic bacteria Escherichia coli, Shizella dysenteriae, Salmonella typhi, Pseudomonas aeruginosa Vibrio cholerae using agar well diffusion method. Only extract all them exhibited an inhibiting effect on the develop...
The eye harbours bacteria from the time of birth throughout life. Owing to its antibacterial properties, the normal conjunctival flora plays a significant role in the defence against superficial ocular infections. In view of its protective action as well as its probable role in causing ocular disease under certain circumstances, the study of the normal flora and its pattern of antibiotic suscep...
Background: The increasing use of telecommunication devices such as Wi-Fi modems and mobile phones in the recent years can change the cellular structure of microorganisms so the generation of electromagnetic waves has led to concern in the community whenever be exposed to these fields and may have harmful effects on human health.Material and Methods: Standard strains of bacteria were prepared o...
Detection of Adhesion Encoding Genes, Antibacterial Susceptibility Test and Biofilm Formation Uropathogenic Escherichia coli Isolated from Urinary Tract Infections in Children
To determine the frequency and pattern of antibiotic susceptibility of uropathogens in urinary tract infection (UTI) from 3 university hospitals we carried out a retrospective review of urine culture and antibiotic sensitivity testing from symptomatic outpatients and inpatients during 2002-2003. Of 5600 samples, 703 (12.6%) were culture positive, 38.7% of which were from hospitalized patients. ...
Two patients (patients A and B) infected with Salmonella typhimurium failed ciprofloxacin therapy, and the posttherapy isolates had reduced susceptibilities to quinolones; 6 of 11 isolates from patient B were also cross-resistant to chemically unrelated agents. No transferable resistance, chloramphenicol-acetylating enzymes, or beta-lactamases were detected. For 13 of 14 isolates, the concentra...
Currently, a standard third-line therapy for Helicobacter pylori (H. pylori) eradication remains to be established. Quinolones show good oral absorption, no major side effects, and marked activity against H. pylori. Several authors have studied quinolone-based third-line therapy and reported encouraging results, with the reported H. pylori cure rates ranging from 60% to 84%. Resistance to quino...
This study investigates the antibacterial mechanism of action of electrospun chitosan-based nanofibers (CNFs), against Escherichia coli, Salmonella enterica serovar Typhimurium, Staphylococcus aureus and Listeria innocua, bacteria frequently involved in food contamination and spoilage. CNFs were prepared by electrospinning of chitosan and poly(ethylene oxide) (PEO) blends. The in vitro antibact...
