Several observational studies have shown a better late outcome in patients with coronary bifurcation lesions treated with stents in whom the side branch was not stented. Balloon dilation and provisional stenting for the side branch seem an attractive strategy to manage these challenging types of lesions. This study evaluated the results of a three-step(More)
There is limited information about the pathogenesis and epidemiology of foot-and-mouth disease (FMD) in North American bison (Bison bison) or elk (Cervus elaphus nelsoni). In these two experimental infection studies, we compared the susceptibilities of bison and elk to FMD virus (FMDV), respectively, with that of cattle; determined whether intra- and(More)
Here we used a multigene sequencing approach for the identification and molecular typing of environmental mycobacteria of the fast-growing subgroup. Strains were isolated from hemodialysis water and clinical samples. Eleven type strains of related species of the genus were also included in this study. To gain further insight into the diversity of the(More)
Six mycobacterial isolates from haemodialysis water, conforming a homogeneous phylogenetic group in a previous multigenic analysis, were classified taxonomically. Physiological and biochemical characterization, as well as DNA-DNA hybridizations, demonstrated that the isolates were facultatively autotrophic, aerobic and hydrogen-oxidizing bacteria,(More)
BACKGROUND The World Health Organization reported in 2007 that inclusion of PCV7 in national immunization programs should be seen as a priority, also encouraging countries to conduct appropriate surveillances for monitoring the impact of vaccination. These analyses should be conducted in specific geographical areas and should be aimed to evolution of(More)
The aim of this study was to determine personal hygiene protocols and animal avoidance periods needed to prevent transmission of FMDV (O/TAW/97). Forty-six, 9-week-old barrows free of FMDV were randomly allocated to five treatment groups and a control group. Investigators contacted and sampled FMDV-inoculated pigs for approximately 40 min and then contacted(More)
Here, we report the complete genome sequence of Mycobacterium immunogenum type strain CCUG 47286, a nontuberculous mycobacterium. The whole genome has 5,573,781 bp and covers as many as 5,484 predicted genes. This genome contributes to the task of closing the still-existing gap of genomes of rapidly growing mycobacterial type strains.
