three marine bacteria, pseudomonas putida ptcc 1664, bacillus cereus  pttc 1665 and pseudomonas pseudoalkaligenes ptcc 1666 isolated from the east anzali wetland sediments of the caspian sea, were resistant to heavy metals of cadmium (cd), nickel (ni) and vanadium (v). pseudomonas pseudoalkaligenes ptcc 1666 was found to be resistant to all 3 metals ni, cd, v. heavy metal uptake was determined ...

introduction: many post-surgical wound infections in hospitals cause morbidity and morality of patients and these are usually transmitted via hands of surgical personnel. the aim of the present study was to detect and antibiogram the bacterial agents following scrubbing of hands of surgical personnel before operation. methods: hands of 134 personnels of operation room were swabbed following scr...

background and objective: probiotics are live microbial feed supplements which beneficially affect the host animal by improving its intestinal microbial balance, producing metabolites which inhibit the colonization or growth of other microorganisms or by competing with them for resources such as nutrients or space. the aim of this study was to investigate the probiotic properties of candida fam...

the present study was aimed to isolate and characterize the lipolytic enzyme producing bacteria from soil samples of regions around zayande-rood river of isfahan, iran. soil samples were collected from 15 cm depth of soil surface. based on morphology, distinct colonies were isolated and purified through streak culture on to standard agar plates. isolated colonies were examined for lipase activi...

this study utilized molecular methods to identify 22 isolates from traditional dairy products of azerbaijan. pcr was carried out using the universal primers of 16s rdna and a fragment of ~1500bp was amplified. amplified ribosomal dna restriction analysis was performed using bsuri, mspi, hindiii, taqi and bsp143i. ardra results were compared to the restriction profile in enzymatic restriction an...

background: it is estimated that about 50% of causes of recurrent pregnancy loss (rpl) cases remain unknown. sperm factors are suggested to have probable role in cases with rpl. objective: the goal was to determine the possible relationship between semen bacterial contaminations with unexplained rpl. also, the correlation between number of bacterial colony and sperm chromatin condensation was e...

background: microorganisms on various surfaces in industrial and residential environments can spread infectious diseases. their control is thus a major concern. the aim of this study was to survey the bacterial contamination of elevator buttons in schools of isfahan university of medical sciences, isfahan, iran in the summer of 2011. methods: this study was done as a cross sectional research. a...

The biological variety of aquatic ecosystems is significantly impacted by the chemical and microbiological composition water bodies, there strong reciprocal feedback between these two factors, especially for reservoirs, which can do have a significant impact on neighboring ecosystems. Today an acute need to identify most effective economically feasible methods cleaning restoring bodies. Therefo...
