To study the putative transfer of antibiotic resistance from broiler breeders to human, hen’s eggs and theirday-old chicks were examined for the presence of bacteria. The most frequently isolated organisms indecreasing order were: Streptococcus spp., Bacillus spp., Staphylococcus spp., Klebsiella spp., Enterobacterspp. and Escherichia coli followed by Citrobacter spp., Proteus spp. and Pseudomo...
conclusions minimum biofilm eradication values of ciprofloxacin obtained in the study are close to the values of the minimal inhibition concentration (mic). results all tested strains formed a biofilm. a value of 1.0 μg/ml ciprofloxacin is mbe50 for the strains of both tested species. an mbe90 value of ciprofloxacin for isolates of p. vulgaris was 2 μg/ml and for p. mirabilis was 512 μg/ml. mat...
conclusions optimization of medium composition and synergistic antimicrobial activity on the cyanobacteria could lead to production of effective antimicrobials. results c. leptolyngbya had antimicrobial activity individually and in synergy with antibiotics against gram-positive and gram-negative bacteria. the highest activity of the chloroform extract was on gram positive strains and its effect...
—Fry of rainbow trout Oncorhynchus mykiss held as sentinel fish became infected with Myxobolus cerebralis when held at all juvenile acclimation sites for spring Chinook salmon O. tshawytscha and steelhead O. mykiss (anadromous rainbow trout) and thus expand the known range of M. cerebralis in northeastern Oregon. In spring 2001, replicate cages of rainbow trout fry were placed at the intake sit...
A total of 1,013 isolates of Enterobacteriaceae were identified in parallel by the Repliscan (Cathra International, Ontario, Canada) and API 20E (Analytab Products, Plainview, N.Y.) systems. There was a 62% agreement at the genus level between the two systems. Of the 38% discrepant results, Repliscan classified 22% as "biochemical pattern not on file," 8% as a multiple-genus group which include...
conclusions bacteria from biological waste were competent producers of pg and must be used on an industrial scale to cope with the demand of pg in the food industry. results among the bacillus, bacillus vallismortis (jq990307) isolated from mango was the most competent producer of pg; producing up to 4.4 u/µl. amongst pseudomonas, pseudomonas aeruginosa (jq990314) isolated from oranges was the ...
Whirling disease is a serious problem that impacts wild and hatchery salmonid stocks across the globe. Whirling disease is caused by a microscopic parasite, Myxobolus cerebralis, with a complex life history involving both salmonid and oligochaete worm hosts. In this study, we investigated the capability of wildland firefighting foams to inactivate M. cerebralis by indirect methods. Specifically...
Cage-cultured sutchi catfish Pangasius hypophthalmus (Sauvage, 1878), a favourite food fish in Southeast Asia, proved to be infected by 6 myxozoan species. Three species belonged to the genus Hennegoides (H. berlandi, H. malayensis, and H. pangasii), 1 to Henneguya (H. shariffi) and 2 to Myxobolus (M. baskai, and M. pangasii). Five myxozoans infected the gills and 1 was found on the spleen. Myx...
صمغ زانتان یک اگزوپلی ساکارید میکروبی و بیوپلیمری با کاربرد های گسترده در صنایع مختلف است. بیشتر مطالعات، وابستگی آشکاری میان سویه مورد استفاده و بازده و ویژگی های صمغ زانتان را گزارش می دهند و جداسازی سویه های xanthomonas spp. از زیستگاه های طبیعی هنوز کاراترین روش غربالگری سویه هایی با توانایی تولید زانتان و کیفیت رئولوژیکی بالا می باشد. در این مطالعه 71 نمونه از خاک زمین های زراعی حومه شهره...
