    Effect of temperature and food concentration in two species of littoral rotifers (1998)
    Springer
    Hydrobiologia 387-388 (1998), S. 341-348 
    Details
    ISSN: 1573-5117
    Keywords: Lecanidae ; life-table ; mortality ; reproduction rate ; survivorship

    Topics: Biology
    Notes: Abstract We performed life-table experiments with two species of the littoral rotifers Lecane luna (O.F. Müller, 1776) and Lecane quadridentata (Ehrenberg, 1832). Three different temperatures (20, 25 and 30°C) and food concentrations of Nannochloris oculata (1×107, 5×106, and 1×106 cells ml-1) were investigated. We found important differences between both species in all the treatments regarding offspring sizes, hatching percentages, life span and reproductive rates. Our data on hatching percentages of asexual eggs suggested that the optimal temperature for both species is in the 20–25°C range. On the other hand, reproductive data placed the optimal temperature near 25°C. This information can be used to develop aquatic toxicology tests with littoral species.

    Relationship between thigmotropism and Candida biofilm formation in vitro (1998)
    Springer
    Mycopathologia 144 (1998), S. 125-129 
    Details
    ISSN: 1573-0832
    Keywords: biofilm ; Candida albicans ; Candida tropicalis ; saliva ; serum ; thigmotropism

    Topics: Biology , Medicine
    Notes: Abstract The biofilm formation of the oral fungal pathogen Candida on denture acrylic strips coated with saliva or serum was examined in relation to the ability to induce hyphae by thigmotropic reaction, using C. albicans (4 isolates), C. glabrata (3 isolates) and C. tropicalis (3 isolates). Both the degree of biofilm formation and the amount of hyphae exhibiting thigmotropism varied depending upon both the species and strains of Candida. Although there was no significant correlation between the amount of hyphae induced by thigmotropic reaction of fungal isolates and biofilm formation on uncoated control specimens (r = 0.577; p 〈 0.05), the ability of hyphae induced by thigmotropic reaction significantly correlated with the amount of both saliva- and serum-admixed biofilms (r = 0.734; p 〈 0.05 and r = 0.793; p 〈 0.01, respectively). Taken together our in vitro data suggested that the hyphal induction by thigmotropic reaction is of importance in candidal biofilm formation on saliva- or serum-coated acrylic surfaces.
