The emergence and rapid spread of unusual DS-1-like intergenogroup reassortant rotavirus strains have been recently reported in Asia, Australia, and Europe. During rotavirus surveillance in Thailand in 2013-2014, novel DS-1-like intergenogroup reassortant strains having G8P[8] genotypes (i.e., strains KKL-17, PCB-79, PCB-84, PCB-85, PCB-103, SKT-107, SWL-12, NP-130, PCB-656, SKT-457, SSKT-269, ...

Escherichia coli strains causing human extra-intestinal infections may be divided into two groups, B1 and B2 according to the electrophoretic patterns of carboxylesterase B. This study compares the restriction fragment length polymorphism (RFLP) of ribosomal DNA (rDNA) for 45 B1 strains and 45 B2 strains to examine the genetic structure of B2 strains and to distinguish them from B1 strains. The...

Polsinelli, M. (University of Pavia, Pavia, Italy), O. Ciferri, G. Cassani, and A. Albertini. Mechanism of resistance to actinomycin in Bacillus subtilis. J. Bacteriol. 88:1567-1572. 1964.-Strains of Bacillus subtilis were rendered resistant to actinomycin D by serial transfer in increasing concentrations of the drug. Resistance to the antibiotic appeared to be due to an altered cell-wall perme...

The aim of the study was to assess the organoleptic differences of Clarias gariepinus smoked with two different energy sources, Anogeissus leiocarpus and Tamarindus indica with the help of a hedonic scale and to determine possible proximate composition difference between the smoked products. Smoking of the fishes was carried out for 4 hours using traditional smoking kiln, the chemical analysis ...

Computed tomography (CT) currently has the greatest sensitivity and specificity of imaging modalities used for the diagnosis of renal colic. When compared with ultrasound, non–contrast-enhanced CT is more sensitive in identifying obstructing ureteral stones and more accurate in measuring stone size. CT also more consistently locates the specific site of obstruction along the course of the urete...

A screening for oxalate degrading abilities was initially carried on within Lactic Acid Bacteria cultures of different food origin. Seventy-nine strains were drop-inoculated onto MRS agar plates containing calcium oxalate. By comparing colonies diameters, 31 strains were used to inoculate, in parallel, MRS and MRS modified by sodium oxalate addition. Differences in the strains' growth were asse...

A model was proposed to describe the relative performance of varieties over a series of environments as a way of improving plant breeding methodology. Data from three experiments were examined to evaluate the usefulness of the model and to obtain some preliminary information on inheritance. Considerable genetic variation was noted for the first stability parameter, response to environmental con...
