BACKGROUND: Blastocystis is a cosmopolitan protist parasite found in the human gastrointestinal tract and is highly prevalent in developing countries. Recent molecular studies have revealed extensive genetic diversity, which has been classified into different subtypes (STs) based on sequence analysis of small subunit ribosomal RNA gene. Blastocystis is one of the most common fecal parasites in Brazil, but the diversity of subtypes remains unknown in the country. This study aimed to determine the distribution of Blastocystis STs in an urban community in Duque de Caxias, Rio de Janeiro, Brazil...

Understanding waterborne protozoan parasites (WPPs) diversity has important implications in public health. In this study, we evaluated a NGS-based method as a detection approach to identify simultaneously most important WPPs using 18S rRNA high-throughput sequencing. A set of primers to target the V4 18S rRNA region of WPPs such as Cryptosporidium spp., Giardia sp., Blastocystis sp., Entamoeba spp, Toxoplasma sp. and free-living amoebae (FLA) was designed. In order to optimize PCR conditions before sequencing, both a mock community with a defined composition of representative WPPs and a real water sample inoculated with specific WPPs DNA were prepared...

Patients with human immunodeficiency virus (HIV) infection are more prone for gastrointestinal infections causing diarrhoea, particularly with parasites. Parasitic infections have been regularly reported in such patients. A female patient confirmed positive for HIV 1 on antiretroviral therapy came with complaints of chronic diarrhoea for the past 7 months. Her initial CD4 count was 89 cells/μl of blood, and antibodies to cytomegalovirus and herpes simplex virus 1 and 2 virus were found to be positive in the patient's serum, but there was no HIV-associated retinopathy...

The classic presentation of acute gastrointestinal (GI) parasitic infection including fever, diarrhea, nausea, and/or abdominal pain is not always a reliable measure. In these cases, parasitic infections require sensitive stool testing to be identified and treated effectively. The standard practice for stool analysis typically requires 3 separate stool specimens to be collected on 3 separate days to overcome the possibility of misdiagnosis due to intermittent shedding. Nonetheless, this practice is not often utilized due to very short periods of sample viability, which often leads to patient misdiagnosis...

Globally, approximately 2 billion people lack microbiologically safe drinking water. Boiling is the most prevalent household water treatment method, yet evidence of its health impact is limited. To conduct this systematic review, we searched four online databases with no limitations on language or publication date. Studies were eligible if health outcomes were measured for participants who reported consuming boiled and untreated water. We used reported and calculated odds ratios (ORs) and random-effects meta-analysis to estimate pathogen-specific and pooled effects by organism group and nonspecific diarrhea...

Proteogenomics, the integrative analysis of the proteome and the genome, increasingly provides protein-level insights about the regulation of gene expression and protein translation. Armengaud et al. (Proteomics 2017. volume, pages) nicely illustrate this trend with the first in depth proteomic analysis of the eukaryotic and unicellular intestinal parasite Blastocystis sp. Not only this work constitutes an important milestone towards the proteogenomics profile of this human pathogen, but also it demonstrates at the protein level the occurrence of a specific mechanism of mRNA decoding...

Blastocystis is the most prevalent eukaryotic microbe colonizing the human gut, infecting approximately 1 billion individuals worldwide. Although Blastocystis has been linked to intestinal disorders, its pathogenicity remains controversial because most carriers are asymptomatic. Here, the genome sequence of Blastocystis subtype (ST) 1 is presented and compared to previously published sequences for ST4 and ST7. Despite a conserved core of genes, there is unexpected diversity between these STs in terms of their genome sizes, guanine-cytosine (GC) content, intron numbers, and gene content...
