Analysis of the synaptonemal complex of the nine-banded armadillo, Dasypus novemcinctus
Provedor de dados: Genetics and Molecular Biology
Autores: Scavone,Márcia Denise da Paixão; Oliveira,Claudio; Bagagli,Eduardo; Foresti,Fausto.
The synaptonemal complex (SC) of three specimens of the nine-banded armadillo (Dasypus novemcinctus) was analyzed. Thirty-two bivalents (2n = 64) were observed, 31 of them being autosomes and one an XY sexual bivalent. Chromosome synapsis processes and nucleolus structure changes were analyzed in zygotene and pachytene cells, allowing a detailed description of the beginning of meiotic prophase in this species. There was complete synapsis of X and Y chromosomes. Some abnormalities in SC were observed in cells during zygotene and at the beginning of pachytene, but not in cells in the middle and late pachytene, suggesting the occurrence of synaptic adjustments in their SC.

Experimental infections with Paracoccidioides brasiliensis obtained from armadillos: comparison to clinical isolates
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Nishikaku,Angela Satie; Peraçoli,Maria Terezinha S.; Bagagli,Eduardo; Sugizaki,Maria Fátima; Sartori,Alexandrina.
Paracoccidioides brasiliensis causes paracoccidioidomycosis (PCM) that is one of the most prevalent systemic human mycoses in Latin America. Armadillos show a high incidence of PCM infection and could, therefore, be a natural reservoir for this fungus. In this study were compared the virulence profiles of isolates obtained from nine-banded armadillos (Dasypus novemcinctus) (PbT1 and PbT4) and isolates from PCM patients (Pb265 and Bt83). Pathogenicity was evaluated by fungal load and analysis of colony morphology. Immunity against the fungus was tested by delayed type hypersensitivity test (DTH) and antibody quantification by ELISA. The higher virulence of PbT1 and PbT4 was suggested by higher fungal load in spleen and lungs. Armadillo isolates and Bt83...

Search for Mycobacterium leprae in wild mammals
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Pedrini,Sílvia Cristina Barboza; Rosa,Patrícia Sammarco; Medri,Ísis Meri; Mourão,Guilherme; Bagagli,Eduardo; Lopes,Carlos Alberto de Magalhães.
Leprosy is still a worldwide public health problem. Brazil and India show the highest prevalence rates of the disease. Natural infection of armadillos Dasypus novemcinctus with Mycobacterium leprae has been reported in some regions of the United States. Identification of bacilli is difficult, particularly due to its inability to grow in vitro. The use of molecular tools represents a fast and sensitive alternative method for diagnosis of mycobacteriosis. In the present study, the diagnostic methods used were bacilloscopy, histopathology, microbiology, and PCR using specific primers for M. leprae repetitive sequences. PCR were performed using genomic DNA extracted from 138 samples of liver, spleen, lymph nodes, and skin of 44 D. novemcinctus, Euphractus...

Candida species biofilm and Candida albicans ALS3 polymorphisms in clinical isolates
Provedor de dados: Brazilian Journal of Microbiology
Autores: Bruder-Nascimento,Ariane; Camargo,Carlos Henrique; Mondelli,Alessandro Lia; Sugizaki,Maria Fátima; Sadatsune,Terue; Bagagli,Eduardo.
Over the last decades, there have been important changes in the epidemiology of Candida infections. In recent years, Candida species have emerged as important causes of invasive infections mainly among immunocompromised patients. This study analyzed Candida spp. isolates and compared the frequency and biofilm production of different species among the different sources of isolation: blood, urine, vulvovaginal secretions and peritoneal dialysis fluid. Biofilm production was quantified in 327 Candida isolates obtained from patients attended at a Brazilian tertiary public hospital (Botucatu, Sao Paulo). C. albicans ALS3 gene polymorphism was also evaluated by determining the number of repeated motifs in the central domain. Of the 198 total biofilm-positive...
