Since enterohemorrhagic Escherichia coli O157, Salmonella, etc., sometimes contaminate animal feces and may cause infectious diseases to humans, it is important to remove pathogenic bacteria from domestic animal waste. For the purpose, we examined the antibacterial activity of chaff vinegar. We found that the chaff vinegar inhibited the growth of pathogenic bacteria immediately in vitro but not...

Objective: Microorganisms are responsible for many problems in industry and medicine because of biofilm formation. Therefore, this study was aimed to examine the effect of Thymus vulgaris (T. vulgaris) extracts on the planktonic form and biofilm structures of six pathogenic bacteria. Materials and methods: Antimicrobial activities of the plant extracts against the planktonic form of the bacteri...

Background: Nowadays, it is needed to explore new routes to treat infectious bacterial pathogens due to prevalence of antibiotic-resistant bacteria. Antimicrobial photothermal therapy (PTT), as a new strategy, eradicates pathogenic bacteria.Objective: In this study, the antimicrobial effects of a carbon nanoparticles-polypyrrole nanocomposite (C-PPy) upon laser irradiation were investigat...

Pathogenicity islands represent distinct genetic elements encoding virulence factors of pathogenic bacteria. Pathogenicity islands belong to the class of genomic islands, which are common genetic elements sharing a set of unifying features. Genomic islands have been acquired by horizontal gene transfer. In recent years many different genomic islands have been discovered in a variety of pathogen...

Multicellular organisms live in environments containing diverse nutrients and a wide variety of microbial communities. On the one hand, immune response can protect from intrusion exogenous microorganisms. other dynamic coordination anabolism catabolism is necessary factor for growth reproduction. Since production an energy-intensive process, activation cells accompanied by metabolic transformat...

During 2008, a study has been conducted on the potential of Alphitobius diaperinus as a reservoir of many poultry pathogenic bacteria, in twenty broiler houses in the North-East of Algeria. Many groups of bacteria have been enumerated; Salmonella and thermophilic campylobacters contaminations have been searched. Both adults and larvae carried and harbored multiple species and numbers of poultry...

BACKGROUND Previous researches about necrotic pancreatic tissue infections are numerous, but the study on systemic infection related to the severe acute pancreatitis (SAP) treatment period is limited. This study aimed to investigate the distribution and drug resistance of pathogenic bacteria in patients who had hepatobiliary surgery for SAP during the past three years. METHODS A retrospective...
