For whole-genome analysis in a basal chordate (protochordate), we used F1 pseudo-testcross mapping strategy and amplified fragment length polymorphism (AFLP) markers to construct primary linkage maps of the ascidian tunicate Ciona intestinalis. Two genetic maps consisted of 14 linkage groups, in agreement with the haploid chromosome number, and contained 276 and 125 AFLP loci derived from cross...

A total of 385 urine specimens from suspected urinary tract infections were subjected to bacteriological analysis and susceptibility testing at a major university hospital laboratory in Tehran. A battery of eight beta-Iactam antibiotics, commonly prescribed in Iran, and three third-generation cephalosporins (ceftazidime, ceftriaxone and ceftizoxime) that are usually reserved for limited us...

Increased mortality and problems with lameness were reported in Dutch broiler flocks from the year 2008 onwards. Therefore, a field inventory, including 10 affected broiler flocks, nine corresponding broiler breeder flocks and five hatcheries, was carried out. The onset of clinical signs (lameness and increased mortality) started at about 2 weeks of age. The flock mortality varied from 3.1 to 8...

Mating studies were conducted on 78 isolates of Fusarium species section Liseola from rice, sugarcane and maize. From the crosses with tester strains of Gibberella fujikuroi species complex, 64.1% (50 out of 78 isolates) were cross-fertile with tester strains of mating populations A to E. The results of the mating studies showed that of the 50 isolates, 19 belonged to mating population A (Gibbe...

Xanthomonas campestris pv. (Xcc) is a harmful pathogen of the Brassicaceae agricultural plants in Serbian agroecological conditions. The bacterium survives soil, plant residues, seeds, and wild weedy plants. This study aimed to characterize Xcc isolates that persist field soil roots where they represent risk causing disease Collection samples was carried out period 2015 - 2017 four locations re...

Emiliania huxleyi is a unicellular marine alga that is considered to be the world's major producer of calcite. The life cycle of this alga is complex and is distinguished by its ability to synthesize exquisitely sculptured calcium carbonate cell coverings known as coccoliths. These structures have been targeted by materials scientists for applications relating to the chemistry of biomedical mat...
