First isolation of Cryptococcus gattii molecular type VGII and Cryptococcus neoformans molecular type VNI from environmental sources in the city of Belém, Pará, Brazil
First isolation of Cryptococcus gattii molecular type VGII and Cryptococcus neoformans molecular type VNI from environmental sources in the city of Belém, Pará, Brazil
Cryptococcus neoformans and Cryptococcus gattii are important
agents of meningoencephalitis in humans in the city of Belém. This
clinical data suggests that the region may be a highly endemic area for
the pathogenic Cryptococcus species within the state of Pará
(PA), Northern Brazil. Preliminary analysis of 11 environmental samples
from the city of Belém showed two positive locations, including a
hollow of a kassod tree (Senna siamea) colonized simultaneously by C.
gattii molecular type VGII and C. neoformans molecular type VNI, and a
birdcage in a commercial aviary positive for C. neoformans, molecular
type VNI. This is the first evidence of an environmental occurrence of
molecular types VNI and VGII in PA
Low frequency of human papillomavirus detection in prostate tissue from individuals from Northern Brazil
The presence of human papillomavirus (HPV) was evaluated in 65 samples
of prostate tumours and six samples of prostates with benign prostatic
hyperplasia from individuals from Northern Brazil. We used a highly
sensitive test, the Linear Array HPV Genotyping Test, to detect 37 high
and low-risk HPV types. In this study, only 3% of tumour samples showed
HPV infection. Our findings support the conclusion that, despite the
high incidence of HPV infection in the geographic regions studied, HPV
was not associated with a higher risk of prostate cancer. To our
knowledge, this is the first study evaluating the frequency of HPV
detection in prostatic tissue of individuals from Brazil
