Bu çalışmada, Ege bölgesinden toplanan turunçgil meyvelerinin (mandalina, limon, greyfurt, portakal) kabuk ve yapraklarından (taze kurutulmuş) elde edilen etanol ekstraktlarının, gıda kaynaklı üç Gram pozitif (Staphylococcus aureus, Listeria monocytogenes, Bacillus cereus) dört negatif (Salmonella Typhi, Enterobacter aerogenes, Pseudomonas aeroginosa) patojen bakteri türü üzerindeki antimikrobi...

OBJECTIVE To evaluate physico-chemical properties and antimicrobial potential of indigenous honey samples against different reference strains including Escherichia coli ATCC 8739, Enterobacter aerogenes ATCC 13048, Pseudomonas aeroginosa ATCC 9027, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, Salmonella typhi ATCC 14028, Klebsiella pneumonia ATCC 13883, Aspergillus niger ATCC ...

Saprolegnia is one of? the? ?most important agents decreasing the eggs survival rate in sturgeon hatcheries. There are some chemical substances for controlling the fungal infection of eggs. In this study, an attempt was made to introduce a ?germ negative bacterium, Pseudomonas aeroginosa (PTCC1430)(Persian Type Culture Collection) as a biocontrol??ling agent of? ?water mold. Saprolegnia was...

Background and Objectives: Nosocomial infections are one of the most important worldwide health and increased patients hospital stay, therapeutic problem and mortality rate. This study was designed to determine the frequency of microorganisms isolated from tracheal tube in patients admitted to ICU Shaheed Mostafa Khomeini Hospital Tehran, Iran, from 2001-2005. Patients and Methods: In this cros...

The ligand, N,N'-bis(salicylidine)ethylenediamine or salen (L), and its complexes 1-3 with Ni(II), Cu(II) Mn(II) were synthesized. Various analytical methods such as microanalysis, 1H-NMR, 13C-NMR, ESI-MS FT-IR spectroscopy has been used to characterize the synthesized compounds. Antibacterial activity of prepared compounds tested against two Gram-positive bacteria Staphylococcus aureus Bacillu...

Soil microbial diversity is an important index of agricultural productivity by enhancing soil quality. Present study employed the combination of several methodologies to examine genetic relationships among specific groups of bacteria and to characterize strains at the species level using molecular biotyping techniques. The present study is based upon 16SrDNA analysis for characterisation of bac...

No ano de 2019 iniciou-se os primeiros casos do novo vírus no mundo, na cidade Wuhan China. Por ser fácil disseminação rapidamente chegou ao Brasil mês fevereiro 2020, sendo declarado uma pandemia. O tem a transmissão pelas vias aéreas, por isso foram utilizados novos métodos para possível controle da doença. Este trabalho pretende avaliar artigos que falem prevalência Pseudomonas aeruginosa em...

background :     river and underground waters are main sources of tap water in guilan, iran. overland wastes move into rivers during periods of heavy or extended rain that is very common in the area. pseudomonas aeruginosa , legionella pneumophila , and escherichia coli are main human pathogens with water source. this study is designed to determine the load of these bacteria in main water suppl...
