Three dictyostelid isolates were found in Spain and Argentina that are morphologically different from known species. These isolates have some features similar to Dictyostelium sphaerocephalum (Oudem.) Sacc., Marchal & É.J. Marchal, but differ in size and sorocarp branching pattern. We sequenced the nuclear ribosomal internal transcribed spacer region to explore phylogenetic relationships among ...

A total of 520 clinical and environmental isolates of the family Micrococcaceae that fermented glucose anaerobically were tested for their ability to produce coagulase, thermostable nuclease, and deoxyribonuclease. Of these, 450 isolates coagulated rabbit plasma, produced thermostable nuclease, and were identified as Staphylococcus aureus, 447 of which produced a 3+ to 4+ clot. The remaining th...

background : infections resulted from multi-resistant staphylococcus aureus are increasing worldwide. in the present study, a multiplex-pcr assay for the detection of antibiotic resistance genes among s. aureus clinical isolates and for the concomitant identification of these isolates was described. methods : a total of 127 s. aureus isolates were collected from clinical specimens at three teac...

black stem is one of the most important fungal diseases of sunflower which is caused by phoma macdonaldii. this research was conducted to clarify the interactions between a few breeder lines and wild-type accessions of sunflower with seven isolates of phoma macdonaldii, the causal agent, under controlled conditions. the experiment was carried out in randomized complete block design with three r...

Forty-four Thai isolates phenotypically assigned to the genus Gluconobacter were examined for 16S-23S rDNA ITS restriction analysis by MboII and SduI ( Bsp1286I) digestions. The Thai isolates tested were divided into seven groups: Group I for fourteen isolates, Group IX for one isolate, Group X for two isolates, Group V-2 for four isolates, Group XI for three isolates, Group IV for one isolate,...

Water pollution is a major problem in India. Ganga is the most holy river of the country and contributes significantly in Indian economy. Water of river ganga has been polluted seriously in last few years. In the present study few isolates of Salmonella which are not so common in India were isolated from river Ganga were evaluated for the presence of virulence contributing genes. In present stu...
