cultivar of roses (rosa spp.) has been grown in greenhouses in qazvin region of iran for local markets. agrobacterium tumefaciens strains were isolated and identified from six different samples of roses plants imported from the netherland to iran. during august and september of 2012, nearly 2-5% of rose plants in two different greenhouses in the province of qazvin were observed with crown gall ...

Yokenella regensburgei is a fermentative, motile, oxidase-negative, gram-negative bacillus belonging to the Enterobacteriaceae family and an opportunistic human pathogen that caused infections mainly in immunocompromised patients rarely immunocompetent individuals. Y. regensburgei, which generally found well water, insect guts, reptiles nature, can cause different types of such as septic arthri...

Three isolates of an unclassified, oxidase-negative and citrate-positive, gram-negative bacillus belonging to the family Enterobacteriaceae were studied. With the exception of the citrate reactions, these strains most closely resembled Escherichia coli in their biochemical reactivity.

Background: There is an emerging trend of pseudomonas infections in immune-compromised patients, specifically hospital settings. The flagship member this family Pseudomonas aeruginosa, which a major infectious agent. This study assessed the distribution and susceptibility patterns species isolated from various specimens as part surveillance program, order to devise antibiograms. Aim: To determi...

Routine procedures used to isolate Haemophilus ducreyi in a busy laboratory are reported. Identification was based on colony morphology and nutritional and biochemical properties of 120 fresh isolates of H. ducreyi. These isolates grew very well on Gonococcal Agar and Mueller-Hinton Agar incubated at 34 degrees C in candle extinction jars containing moistened filter paper. Colonies varied in si...

The density of sympathetic nerve terminals in human superficial temporal arteries from 5 cases at intra- and extracranial bypass surgery was examined with two histochemical methods, one with potassium permanganate fixation and the other with the new monoamine oxidase staining technique. By potassium permanganate fixation, small cored vesicles containing fibers of noradrenergic nerve terminals m...

A Gram-negative bacillus isolated from the blood of a leukaemic patient with septicaemia was identified on the basis of common tests as Escherichia coli. However, the organism's antibiogram was atypical of E. coli and led to its re-examination and correct identification as Aeromonas hydrophila. A. hydrophila is sensitive to chloramphenicol and tetracycline, characteristics useful in differentia...

an adult female budgerigar (melopsittacus undulatus) presented with abdominal enlargement. the condition of the bird deteriorated after needle aspiration for cytological examination. the budgerigar was euthanatized and a complete necropsy was performed. microscopic sections were prepared and stained with hematoxylin and eosin, gram staining, periodic acid-schiff (pas) and acid-fast staining. es...

Flavobacterium branchiophilum a causative agent of Bacterial Gill Disease (BGD) is a filamentous gram-negative bacteria which produce yellow round colonies in cytophaga agar medium. The outbreak of disease were reported from different part of world. In this study we examined 75 fish sample from farms with a recirculating aquaculture system (n=25), pools with a well water source farms (n=25) and...
