Three groups of gestating gilts and sows (Exp. 1; n = 98) were used to determine the effects of Pichia guilliermondii (Pg), a whole yeast product (CitriStim, ADM Alliance Nutrition), on dam and litter immune parameters. At breeding, gilts and sows were allotted to 1 of 3 treatments maintained through lactation: sow control (SC) diet or SC supplemented with 0.1 (S1) or 0.2% (S2) Pg. Pigs from gr...

Please cite this article in press as: Lahlali, R., et a Morocco under the influence of temperature an The interactions of Penicillium italicum, which causes blue mould, and antagonistic yeast Pichia guilliermondii strain Z1 were examined in controlled environments, to determine the influence of relative humidity (RH) (45%, 75%, 85%, 98%, and 100%) and temperature (T) (5, 10, 15, 20, and 25 C). ...

Candida arabinofermentans PYCC 5603(T) and Pichia guilliermondii PYCC 3012 were shown to grow well on L-arabinose, albeit exhibiting distinct features that justify an in-depth comparative study of their respective pentose catabolism. Carbon-13 labeling experiments coupled with in vivo nuclear magnetic resonance (NMR) spectroscopy were used to investigate L-arabinose metabolism in these yeasts, ...

Yeasts are emerging as important etiological agents of nosocomial bloodstream infections. A multiplex PCR method was developed to rapidly identify clinically important yeasts that cause fungemia. The method amplified the internal transcribed spacer 1 (ITS1) region between the 18S and 5.8S rRNA genes and a specific DNA fragment within the ITS2 region of Candida albicans. With this method, C. alb...

Invasive fungal infections, specifically candidemia, constitute major public health problems with high mortality rates. Therefore, in the last few years, the development of novel diagnostic methods has been considered a critical issue. Herein we describe a multiplex PCR strategy allowing the identification of 8 clinically relevant yeasts of the Candida genus, namely C. albicans, C. glabrata, C....

Studies of the biosynthesis of sphingosine and dihydrosphingosine in whole animals'-4 and in brain tissue homogenates5-8 indicate that the first two carbon atoms of these compounds are derived from serine while the remainder of the molecule is derived from palmitic acid or palmitaldehyde. Brady, Formica, and Koval6 reported that pyridoxal phosphate (PLP), Mn++, nicotinamide, cytidine 5'-diphosp...

Two clones, CA4-2 and CA5-4, which produced agglutinating monoclonal immunoglobulin M (IgM) antibodies (MAbs) against mannan antigens of Candida albicans serotype A, were established. The specificity of each MAb was determined by slide agglutination tests for cross-reactivity patterns against the homologous and six other strains of Candida and a strain of Torulopsis: C. albicans serotype B, C. ...

Yeast infections are common in immunocompromised patients, although emerging species have been changing the epidemiological profile. The ability to secrete proteinases has been associated with pathogenicity within the genus Candida. This study had the aims of diagnosing yeast infections in immunocompromised patients and evaluating the virulence of the etiological agents, based on a proteinase s...

The chromosomal DNAs of eight medically important Candida species, C. albicans, C. stellatoidea, C. tropicalis, C. parapsilosis, C. krusei, C. guilliermondii, C. kefyr and C. glabrata, were analysed by pulsed-field gel electrophoresis under various conditions. The corresponding bands in the gels were assigned by three kinds of DNA probe which hybridized to DNA of all the species: rDNA, TUB2 and...
