Environmental microbiology utilizes indirect methods as microscopy and culture media to its studies. However, these conventional methodologies present problems to quantify and qualify microorganisms and their relation with the environment. The aim of this manuscript was to describe the application of fluorescent in situ hybridization (FISH) in environmental microbiology studies. It was discusse...

Gas production from microbial deterioration in vacuum-packs of chilled meat leads to pack distension, which is commonly referred as blown pack. This phenomenon is attributed to some psychrophilic and psychrotrophic Clostridium species, as well as Enterobacteria. The ability of these microorganisms to grow at refrigeration temperatures makes the control by the meat industry a challenge. This typ...

the objective of this study was to determine the frequency of microorganisms isolated from blood samples of patients admitted to intensive care unit (icu), and the rate of their resistance to common administered antibiotics in an iranian icu. one-hundred patients with systemic inflammatory response syndromes (sirs), hospitalized in icu of sina hospital, tehran, iran, were entered to this cross-...

In a comparison of 1,368 positive blood cultures, a vented Roche Septi-Chek (V-RSC) blood culture bottle was superior to an unvented tryptic soy broth-containing bottle (Difco) for the recovery of all aerobic and facultatively anaerobic microorganisms. Anaerobic bacteria were recovered more frequently and earlier in the unvented tryptic soy broth-containing bottle. A separate comparison of 529 ...

this study was conducted to compare digestibility of wheat straw (ws) by fungi and whole rumen microorganisms (wrm). dry matter (dm), neutral and acid detergent fiber (ndf and adf) digestibility of ws were compared with in vitro digestion (ivd), gas production (gp) and specific rumen anaerobic fungi culture (srafc). dry matter, ndf and adf digestibility of ws by wrm of buffalo (60.80, 49.93 and...

A compartmented, autoclavable culture vessel has been developed for the purpose of studying interactive associations of microorganisms which are essential to the anaerobic decomposition of sewage sludge. The unit employs sterile filter membranes to subdivide the interior culture space into individual compartments. Bacteria cultured in one compartment are denied access to adjacent compartments, ...

Aim. To demonstrate the possibility of using a batch culture model to study interaction Salmonella Enteritidis and Salmonell Typhimurium, which are currently leading serotypes in etiology salmonellosis, an vitro experiment both among themselves combination with Yersinia pseudotuberculosis Shigella flexneri . Materials methods. An experimental microorganism associations was created by co-cultiva...

propolis has traditionally been used in curing infections and healing wounds and burns. current researches have shown that propolis has antibacterial, antifungal and antiviral actions however, the pharmacological activity of propolis is highly variable depending on its geographic origin. there have been few studies on the effects of iranian propolis on the oral microorganisms. in this in-vitro ...

in this article, regarding threefold nature of iranian culture (iranian, islamic, western) and using descriptive- analytic method, it is investigated about ideas of  shariati, soroush amd rajai on iranian culture to use in fusional approach. shariati emphasized on recognizing awareness of islam with passion and action, the efficiency conscious from west instead of blind imitation, knowing tradi...
