The application of ultraviolet (UV) radiation to inhibit bacterial growth is based on the principle that the exposure of DNA to UV radiation results in the formation of cytotoxic lesions, leading to inactivation of microorganisms. Herein, we present the impacts of UV radiation on bacterial cultures’ properties from the biological, biochemical and molecular biological perspective. For experiment...

Algal cultures have been freed of bacterial contamination by a procedure involving treatment with a detergent and phenol, followed by plating on an agar medium for selection of pure cultures.

cultures of viable bacteria were performed in excised tissues. When mice were challenged with S. aureus and immediately afterwards treated with saline (control group), mean bacterial numbers were significantly higher than those in cultures from all other groups (

This study examines the formation of bacterial biofilms on percutaneous wires used for fracture fixation. Twelve control (clinically uninfected) wires and ten infected wires were collected and examined using broth culture and scanning electron microscopy. Three of the 12 control wires grew Staphylococcus spp. with very low bacterial counts in their percutaneous portions. In the clinically infec...

The involvement of the proinflammatory cytokines, interleukin 8 (IL-8) and 6 (IL-6), was studied during the first 72 h of acute invasive gastroenteritis. Study population included 33 infants and young children aged six months to six years and seven age-matched controls. As a group, patients with acute invasive gastroenteritis had an increased serum level of IL-8 and IL-6 as compared with health...

Antimicrobial susceptibility patterns of bacterial meningitis provide essential information regarding selection of antibiotic therapy for patients with bacterial meningitis. This study presents data on causes of bacterial meningitis and their susceptibility pattern among children at Children's Medical Center (CMC), a referral tertiary care center in Iran. In this comprehensive retrospective stu...

Direct detection of enterotoxigenic Escherichia coli (ETEC) in mixed cultures by DNA filter assay was affected by the presence of other bacteria in the cultures. By shortening incubation to 6 h, bacterial overgrowth was minimized, allowing direct detection of ETEC in stools or mixed cultures initially containing 0.2 to 3% ETEC.
