Depression phenotype identified by using single nucleotide exact amplicon sequence variants of the human gut microbiome.

Single nucleotide exact amplicon sequence variants (ASV) of the human gut microbiome were used to evaluate if individuals with a depression phenotype (DEPR) could be identified from healthy reference subjects (NODEP). Microbial DNA in stool samples obtained from 40 subjects were characterized using high throughput microbiome sequence data processed via DADA2 error correction combined with PIME machine-learning de-noising and taxa binning/parsing of prevalent ASVs at the single nucleotide level of resolution. Application of ALDEx2 differential abundance analysis with assessed effect sizes and stringent PICRUSt2 predicted metabolic pathways.

Interaction between Apis mellifera L. and Baccharis dracunculifolia DC, that favours green propolis production in Minas Gerais.

In Minas Gerais, green propolis is produced from the collection of resinous substance found in shoot apices of Baccharis dracunculifolia. The aim of this study was to evaluate the biological parameters associated with the interaction Apis mellifera x Baccharis dracunculifolia, to elucidate the supply of resin for green propolis production in Minas Gerais. We selected male and female individuals of two populations of Baccharis dracunculifolia located on São Judas Tadeu Farm - FSJT, in the municipality of Betim, MG and the Experimental Garden of the Ezequiel Dias Foundation - HORTO, located in an urban area in Belo Horizonte, MG.

[Histoplasmosis in the region of the hard palate simulating a lesion caused by Leishmania].

A case of histoplasmosis at the oral cavity simulating mucocutaneous leishmaniasis is reported. The initial suspicion of leishmaniasis was not confirmed due to lack of amastigotes and no reactivity of the Montenegro's skin test. Diagnosis of histoplasmosis was done by Grocott's stained smears and isolation of Histoplasma capsulatum in Sabouraud's-agar slants.

[Geographic distribution of planorbidae in Santa Catarina, Brazil].

A revision of the malacological surveys carried out in Santa Catarina, Brazil, by the National Health Foundation in 52 counties of 8 microregions between 1981 and 1994 was made. Fifty of them were positive for Biomphalaria tenagophila, the only schistosome vector identified in the 94,535 specimens collected. Of 1,358 districts, 617 (45.
