Periodic culture of Pseudomonas putida strain ATCC 12633=NBPMCC1090 was investigated in a 24 h experiment for sensitivity to zinc oxide thin films constructed under different conditions. The growth of bacteria was followed at every three hours and three methods were used to determine live cells. Optical density, cultivation and microscopic methods were applied and compared. To distinguish activ...

Antibacterial activity of A. sativum was tested against gram-positive and gram-negative bacterial isolates from Urinary Tract of Indian patients, which were confirmed for resistant against commonly used antibiotics for urinary tract infections. In present study, only five quantities (10, 20, 30, 40 and 50μg) of aqueous allicin from A. sativum cloves and leaves were used, which has antibacterial...

Ostreopsis lenticularis Fukuyo 1981, is the major benthic dinoflagellate vector implicated in ciguatera fish poisoning in finfish on the southwest coast of Puerto Rico. Clonal laboratory cultures of O. lenticularis (clone 301) exposed to elevated temperatures (30-31 degrees C) for 33 and 54 days showed significant increases in the quantity of extractable toxin they produced as compared to their...

Resistance of uropathogenic bacteria to antibiotics is an increasing problem in primary health care. The aim of this study was to evaluate antibacterial susceptibility testing of uropathogenic bacteria when performed in general practice. Urine specimens with a known quantity of typically uropathogenic bacteria were sent to 25 general practices. The predictive values of testing a bacterial strai...

The fate and impact of elemental mercury in closed bacterial cultures were examined. The quantity of elemental mercury oxidized by bacteria ranged from small amounts for Pseudomonas aeruginosa, P. fluorescens, Escherichia coli, and Citrobacter to essentially all of the added elemental mercury for Bacillus subtilis and B. megaterium. The percentage of the total mercury in the system associated w...

In this study, we investigate the interaction of Rhodopseudomonas Palustris (R. Palustris) with montmorillonite clay. The adsorption of bacteria on the clay surface was also determined as a function of the initial bacterial quantity, pH, temperature and ionic strength. At different initial bacterial quantities, the percentage of bacteria adsorbed ranged from 61.07% to 77.57%, and the higher per...

PURPOSE Bone collectors are used to harvest bone debris for grafting procedures during implant surgery. The particulate bone debris gathered through filtration has been frequently used in minor regenerative surgical procedures. Nevertheless, the biological potency of such grafts is still unclear. The objective of this study was to systematically review the use of bone collectors in implant dent...

Background and Aims: Bioaerosols are airborne particles that contain bacteria, viruse, and fungi. Human show different reactions to bioaerosols. This study aimed to determine the density of bacterial particles cultivable in the inside and outside air of kindergardens in Birjand, Iran. Materials and Methods: This study was performed based on a descriptive-analytical and cross-sectional research...
