Faster cryptococcus melanization increases virulence in experimental and human ...
Sousa, Herdson Renney de; Oliveira Júnior, Getúlio Pereira de; Frazão, Stefânia de Oliveira; Gorgonha, Kaio César de Melo; Rosa, Camila PereiraCryptococcus spp. are human pathogens that cause 181,000 deaths per year. In this work, we systematically investigated the virulence attributes of Cryptococcus spp. clinical isolates and correlated them with patient data to better understand cryptococcosis. We collected 66 C. neoformans and 19 C. gattii clinical isolates and analyzed multiple virulence phenotypes and host–pathogen interaction outcomes. C. neofo...
MLST reveals a clonal population structure for Cryptococcus neoformans molecula...
Rocha, Diego Fernando Silva; Cruz, Kátia Santana; Silva Santos, Carla Silvana da; Stephanny Fernandes Menescal, Lizandra; Silva Neto, João Ricardo daCryptococcosis is considered endemic in Amazonas state, occurring more frequently in individuals with AIDS, who are predominantly infected by Cryptococcus neoformans molecular type VNI. Infections by Cryptococcus gattii VGII predominate in immunocompetent hosts from the American continent and are associated with outbreaks in North America, particularly the subtypes VGIIa and VGIIb, which are also present in the...
Preheating of urine improves the specificity of urinary cryptococcal antigen te...
Brito-Santos, Fábio; Ferreira, Marcela de Faria; Trilles, Luciana; Muniz, Mauro de Medeiros; Santos, Valdiléa Gonçalves Veloso dosA delay in laboratory diagnosis is related to sequelae and death. Thus, early diagnosis is the key to decrease the high lethality rate due to cryptococcosis. The cryptococcal antigen lateral flow assay (CrAg LFA) Immy test is standardized for a fast screening point-of-care test for cryptococcosis, detecting cryptococcal antigen in serum and cerebrospinal fluid (CSF). Urine screening would be ideal as a noninvas...
FIRST REPORT ON Cryptococcus neoformans IN PIGEON EXCRETA FROM PUBLIC AND RESID...
Takahara, Doracilde Terumi; Lazera, Marcia dos Santos; Wanke, Bodo; Trilles, Luciana; Dutra, Valeria; Paula, Daphine Ariadne Jesus de; Nakazato, LucianoRESUMO A criptococose é micose sistêmica potencialmente grave causada por duas espécies do gênero Cryptococcus que acometem tanto homens como animais: Cryptococcus neoformans e C. gattii. São infecções cosmopolitas e emergentes, resultantes da interação do hospedeiro - humano e animal versus meio ambiente. A proposta deste trabalho foi avaliar a ocorrência de C. neoformans em 122 amostras de excretas secas de p...
