A variety of evidence suggests that the failure of cellular metabolism is one of the underlying causes of neurodegenerative diseases. For example, the inhibition of mitochondrial function produces a pattern of cellular pathology in the striatum that resembles that seen in Huntington's disease. However, neurons can also generate ATP through the glycolytic(More)
Four isolates of a rapidly growing Mycobacterium species had a mycolic acid pattern similar to that of Mycobacterium smegmatis, as determined by HPLC analyses. Three of the isolates were from footbath drains and a sink at a nail salon located in Atlanta, GA, USA; the fourth was obtained from a granulomatous subdermal lesion of a female patient in Venezuela(More)
The development of a liquid-phase blocking sandwich ELISA (LPBE) to measure antibodies (Ab) produced in cattle with the O, A and C foot-and-mouth disease virus (FMDV) types of commercial vaccines used in Argentina is described. The test was specific: 99% of naïve cattle sera (n = 130) gave titres below log10 = 1.2, and none had a titre above log10 = 1.5.(More)
BACKGROUND Among members of the family Enterobacteriaceae, the production of plasmid-mediated extended-spectrum beta-lactamases (ESbetaLs) has emerged as an important mechanism of the resistance to beta-lactams. METHODS The molecular basis of extended-spectrum beta-lactamase in 48 strains of Klebsiella pneumoniae, recovered from neonatal patients with(More)
We report the first case of a post-acupuncture soft tissue infection due to Mycobacterium fortuitum. Two months after finishing an acupuncture treatment session, an immunocompetent 23-year-old woman developed cellulitis at the side of the needle insertions and the acidfast bacillus was isolated from a closed abscess. The patient was successfully treated(More)
