objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...

Assessment of beneficial properties by in vitro approaches forms the basis selection a potential probiotic. Moreover, bacterial strains autochthonous origin are considered more useful than from allochthonous sources. In this study, strain Pseudomonas entomophila COFCAU_PEP4, isolated intestine Indian major carp rohu (Labeo rohita), was evaluated for its probiotic using range tests, along with s...

screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...

background: avian pathogenic escherichia coli (apec), which is the causative agent of colibacillosis, harbors several putative virulence genes. an important trait of apec for both poultry and public health is antibiotic resistance. objectives: in the present study, some potential virulence genes of apecs isolated from northeast of iran and their resistance to the quinolones antibiotics were stu...

introduction: emergency department is one of the most important hospital wards that offers emergency services to unstable patients 24 hours a day, 7 days a week. however, the way the services are offered reflects the general status of the hospital since patients with the most serious problems frequently refer to the emergency department. emergency department waiting time is one of the indices u...

the objective of this study is to measure the city of tehran’s environmental quality in 2006 (the last census year). primarily, with a comparative analysis of a variety of urban sustainability indicator models, a collection of 54 indicators have been chosen and categorized as indicators of increase or decrease in urban environmental quality in the form of a simple mathematical model. based o...

BACKGROUND Indigenous lactic acid bacteria are well known probiotics having antibacterial activity against potentially pathogenic bacteria. This study aims to characterize the curd lactobacilli for their probiotic potentiality and antagonistic activity against clinical bacteria. METHODS Four curd samples were processed microbiologically for the isolation of lactic acid bacteria (LAB). The LAB...

Autoreactive T cells can infiltrate the CNS to cause disorders such as multiple sclerosis. In order to visualize T cell activation in the CNS, we introduced a truncated fluorescent derivative of nuclear factor of activated T cells (NFAT) as a real-time T cell activation indicator. In experimental autoimmune encephalomyelitis, a rat model of multiple sclerosis, we tracked T cells interacting wit...
