Comparison of primers for RAPD-PCR from environmental isolates of Cryptococcus neoformans, Cryptococcus albidus and Cryptococcus laurentii complex BJM
Pedroso,Reginaldo dos Santos; Ferreira,Joseane Cristina; Costa,Karen Regina Carim da; Candido,Regina Celia.
Various organisms have been characterized by molecular methods, including fungi of the genus Cryptococcus. The purposes of this study were: to determine the discriminatory potential of the RAPD (Random Amplified Polymorphic DNA) primers, the pattern of similarity of the Cryptococcus species, and discuss their useful application in epidemiological studies. We analyzed 10 isolates of each specie/group: C. albidus, C. laurentii complex, C. neoformans var. grubii, all from environmental source, and two ATCC strains, C. neoformans var. grubii ATCC 90112, and C. neoformans var. neoformans ATCC 28957 by RAPD-PCR using the primers CAV1, CAV2, ZAP19, ZAP20, OPB11 and SEQ6. The primers showed a good discriminatory power, revealing important differences between them...

Cryptococcus laurentii fungaemia in a cervical cancer patient BJID
Neves,Rejane Pereira; Lima Neto,Reginaldo Gonçalves de; Leite,Melyna Chaves; Silva,Vanessa Karina Alves da; Santos,Franz de Assis Graciano dos; Macêdo,Danielle Patrícia Cerqueira.
ABSTRACT Infections caused by emerging Cryptococcus non-neoformans species are being reported with increasingly frequency. Here, we present a case of fungaemia byCryptococcus laurentii in a woman receiving aggressive immunosuppressive therapy for cervical neoplasia. Three venous blood samples were aseptically collected on consecutive days and C. laurentiiwas isolated and identified through phenotypic and molecular methods. After central venous catheter removal and appropriate antifungal therapy, the patient showed significant improvement and blood culture became negative. Thus, patients following immunosuppressive therapies and using invasive medical devices are at risk of C. laurentii blood infections.

Optimization of lipids production by Cryptococcus laurentii 11 using cheese whey with molasses BJM
Castanha,Rodrigo Fernandes; Mariano,Adriano Pinto; Morais,Lilia Aparecida Salgado de; Scramin,Shirlei; Monteiro,Regina Teresa Rosim.
This study aimed the optimization of culture condition and composition for production of Cryptococcus laurentii 11 biomass and lipids in cheese whey medium supplemented with sugarcane molasses. The optimization of pH, fermentation time, and molasses concentration according to a full factorial statistical experimental design was followed by a Plackett-Burman experimental design, which was used to determine whether the supplementation of the culture medium by yeast extract and inorganic salts could provide a further enhancement of lipids production. The following conditions and composition of the culture medium were found to optimize biomass and lipids production: 360 h fermentation, 6.5 pH and supplementation of (g L-1): 50 molasses, 0.5 yeast extract, 4...

Postharvest application of the yeast Cryptococcus laurentii reduces apple rots. Repositório Alice
BLUM, L. E. B.; AMARANTE, C. V. T.; VALDEBENITO SANHUEZA, R. M..
Rots might be responsible for substantial post-harvest losses on apples (Malus domestica). The blue mold caused by Penicillium expansum, the bitter rot caused by Glomerella cingulata and the ?bull?s-eye rot? induced by Pezicula malicorticis are among the most common rots. Great attention has been given to less environmental damaging alternatives for the control of post-harvest diseases. The post-harvest application of yeasts, such as Cryptococcus laurentii, is one of the options to control fruit rots. This study was carried out to test the efficiency of C. laurentii on fruit rots control in ?Fuji? and ?Gala? apples. After application of treatments by immersion, the fruits were stored in laboratory (15-20°C and 60-70% RH) or in cold storage (1°C and 90-95%...
