    Rarity of luxotonic responses in cortical visual areas of the cat (1980)
    Springer
    Experimental brain research 39 (1980), S. 125-132 
    Details
    ISSN: 1432-1106
    Keywords: Cat ; Visual cortex ; Luxotonic sustained responses

    Topics: Medicine
    Notes: Summary Neuronal responses to continuous, diffuse white light or darkness were studied in cortical visual areas 17, 18, 19 and Clare-Bishop of the unanesthetized cat. In contrast to squirrel monkeys and macaques in which about 40 or 25% of the units in striate cortex are luxotonic (response to continuous light or darkness sustained〉2.0 min), all of the visual areas in the cat had fewer than 4.0% of the units exhibiting such luxotonic activity. The functional basis of this difference may be related to differences between the two species in the quantitative balance of antagonistic receptive field properties.

    Rapid identification of Clostridium botulinum colonies by in vitro toxicity and antimicrobial susceptibility testing (1994)
    Springer
    World journal of microbiology and biotechnology 10 (1994), S. 27-29 
    Details
    ISSN: 1573-0972
    Keywords: Clostridium botulinum ; identification ; immunoassay ; resistance ; toxigenicity

    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Identification of Clostridium botulinum is usually based on toxin detection of broth culture by mouse bioassay and requires 7 to 10 days to complete. Here, we describe an alternative in vitro procedure for direct identification of C. botulinum (types A and B) colonies which can be completed in 48 h. The method is based on toxigenicity of colonies demonstrable by enzyme immunoassay and resistance of C. botulinum to antimicrobial agents, sulpha-methoxazole, trimethoprim and cycloserine.
