    Notes: Methods of the Association of Official Analytical Chemists (AOAC) were compared with the A-l (direct) and the A-l (modified) methods for enumerating fecal coliforms and Escherichia coli in 702 samples, representing 11 food types. Geometric means of fecal coli-form most probable number (MPN) values of samples analyzed by the A-l (direct) and A-l (modified) methods were equal to or significantly higher than the geometric means of samples analyzed by the AOAC method in 9 (82%) and 11 (100%) of the food categories, respectively. Geometric means of E. coli MPNs of samples analyzed by the A-l (direct) and A-l (modified) methods were equal to or significantly greater than the geometric means of samples analyzed by the AOAC method in 4 (36%) and 8 (73%) of the food categories, respectively. Overall, a significant degree of correlation was demonstrated between the AOAC method and the A-l (modified) method in the enumeration of both fecal coliforms and E. coli in the majority of food types used in this evaluation.

    Notes: Using standard procedures, aerobic plate counts (APC), total and fecal coliform most probable number (MPN) determinations, and analyses for Salmonella, Arizona, Shigella and Edwardsiella tarda were performed on 335 fresh and 342 frozen sample units of channel catfish. APC values for 93.0% of the fresh and 94.5% of the frozen samples were 〈inlineGraphic alt="leqslant R: less-than-or-eq, slant" extraInfo="nonStandardEntity" href="urn:x-wiley:00221147:JFDS359:les" location="les.gif"/〉107 organisms per g. Fecal coliform MPN values for 70.7% of the fresh and 92.4% of the frozen samples were 〈inlineGraphic alt="leqslant R: less-than-or-eq, slant" extraInfo="nonStandardEntity" href="urn:x-wiley:00221147:JFDS359:les" location="les.gif"/〉400 organisms per g. The occurrence of Salmonella in channel catfish was subject to seasonal variation. Salmonella-positive samples yielded 15 serotypes from 8 somatic groups. Edwardsiella tarda was isolated from two samples; Arizona and Shigella were not detected.

    Improved Salmonella Species Recovery from Nonfat Dry Milk Pre-enriched Under Reduced Rehydration (1983)
    Oxford, UK : Blackwell Publishing Ltd

    Details

    Notes: Recovery of Salmonella species from nonfat dry milk was performed by the method of the Association of Official Analytical Chemists (AOAC), in which a 25-g sample is rapidly rehydrated in 225 ml of sterile distilled water. Recovery was improved by swirling pre-enriched samples at an initial 1:2 sample/water ratio and diluting 60 min later to a final 1:9 sample/water ratio before incubation at 35°C. In a second improved method, 25-g samples were gently added to 225-ml volumes of sterile distilled water and allowed to soak undisturbed for 60 min at room temperature before incubation. Direct comparison of the AOAC and soak methods showed that 16 and 62 Salmonella-positive samples, respectively, were detected by each of these methods. Sensitivity of the soak method did not decrease during analysis of four 100-g samples or a single 375-g sample as compared with analysis of fifteen individual 25-g samples.

    RAPID IDENTIFICATION OF Salmonella AND RELATED FOODBORNE BACTERIA BY FIVE BIOCHEMICAL MULTITEST SYSTEMS (1977)

    Notes: An evaluation was made of five commercially available “multitest systems” suggested for biochemically differentiating members of the Enterobacteriaceae. Three biochemical kits (Enterotube, PathoTec Rapid I-D System, and Modified Expanded R/B Enteric Differential System) gave incorrect identification for two of 110 Salmonella cultures, whereas two kits (API-20 Enteric and Minitek Differential System) gave correct identification of all 110 Salmonella cultures. The PathoTec Raoid I-D Svstem gave incorrect identification for two of 15 non-Salmonella, whereas the remaining four kits gave incorrect identification for three of these cultures. The overall average correlation for all biochemical tests or substrates evaluated within each system was as follows: API, 99%; Enterotube, 99%; Minitek, 99%; PathoTec, 97%; and R/B, 96%.

    Effect of osmotic pressure on spontaneous afferent discharge in the nerves of the perfused rabbit liver (1975)
    Springer
    Pflügers Archiv 361 (1975), S. 89-94 
    Details
    ISSN: 1432-2013
    Keywords: Osmoreceptors ; Perfused liver ; Hepatic nerves
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Rabbit livers were perfused with Krebs solution via the portal vein and small bundles of the hepatic nerve were monitored for spontaneous afferent impulses arising in the liver. The concentration of the Krebs solution was varied by altering the amount of water in which the salts were dissolved. An alteration from 5% more concentrated to 5% more dilute andvice versa did not affect this spontantous discharge. Addition to the Krebs solution of up to 60 mM sucrose, of up to 22 mM mannitol or of 0.8 mM polyethylenglycol 6000 mol. wt. did not alter the frequency of impulses. Perfusion with bovine serum, or Krebs solution containing approx. 0.6 mM polyvinylpyrrolidone, mol. wt. 44000, or dextran mol. wt. 110 000 increased the frequency of discharge in some nerve bundles. An alteration of 0.06 mM in the concentration of dextran produced a significant change of frequency. It is concluded that spontaneous discharge in some afferent hepatic nerves is influenced by colloidal osmotic pressure but not by changes of ionic osmotic pressure. The nerves affected differ from ‘sodium-sensitive’ nerves and from the ‘osmoreceptors’ of Niijima.
