Abstract:

Blastocystis spp. is the most common enteric parasitic infection found in several community surveys from developing countries. Blastocystis infections may cause gastrointestinal symptoms, but also cause extraintestinal symptoms such as urticaria and joint pain. Blastocystis infection can also be asymptomatic or a carrier. However, the prevalence of Blastocystis infection in children has not yet been fully investigated in Indonesia, particularly in Bali Province.

Abstract:

Background. Blastocystis spp. is a common protozoan found in the gastrointestinal tract, typically existing as a non-pathogenic organism in humans and other animals. However, it can become pathogenic when the immune system is compromised due to bacterial, viral, fungal, or other parasitic infections, as well as systemic conditions, leading to symptomatic blastocystosis. Methods. Fecal samples were collected from patients at the University Hospital of Campania “Luigi Vanvitelli” and Cotugno Hospital in Naples. Among these samples, those that tested positive for Blastocystis spp. and were associ

Abstract:

Blastocystis is a unicellular intestinal organism with undetermined pathogenicity, one of the most commonly detected in human stool samples around the world. Sometimes their presence may contribute to the development of blastocystosis manifested by gastrointestinal complaints such as abdominal pain, diarrhea, flatulence, and nausea of varying severity with periods of exacerbation and remission. Due to the significant polymorphism (at least 4 morphological forms and a large range of sizes), and the delicate, easily degradable structure, recognition of Blastocystis in microscopic stool smears is

Research on endoparasites in pet dogs has been growing, but shepherd dogs have largely been overlooked. These dogs frequently share close proximity not only with sheep, which are reservoirs of zoonotic subtypes of Blastocystis, but also with their owners. This close contact increases the potential for shepherd dogs to act as intermediates in the transmission of Blastocystis. To clarify the role of these dogs as reservoirs for this parasite, this study investigated the presence of Blastocystis in shepherd dogs.

Blastocystis sp. is a common intestinal anaerobic parasite infecting non-human primates and many other animals. This taxon threatens the health of NHPs due to its high genetic diversity, impeding efforts to improve confined management and subsequent conservation practices. This study collected 100 and 154 fecal samples from captive macaques, gibbons, and slow lorises in the summer and winter, respectively. The Blastocystis infection, its gene subtypes, and its zoonotic potential based on small subunit ribosomal RNA (SSU rRNA) were analyzed. The prevalence of Blastocystis in the three primate g

Abstract:

This study provides the first comprehensive investigation of Blastocystis sp. contamination in the drinking well and coastal water sources in Guinea-Bissau, a region grappling with severe water quality challenges. Of the forty-five water samples analyzed (34 well and 9 coastal water sources), Blastocystis sp. was detected in five (11%, 95% CI: 3.71–24.05) of the wells, which serve as a critical and primary drinking source for local communities. The detection of human-associated Blastocystis sp. subtype (ST)2 and ST3 raises concerns about the potential of fecal contamination as a transmission r

Abstract Background Patients with multiple recurrent Clostridioides difficile infections (rCDI) are treated with fecal microbiota transplantation (FMT), using feces provided by healthy donors. Blastocystis colonization of donors is considered an exclusion criterion, whereas its pathogenicity is still under debate. Methods The introduction of molecular screening for Blastocystis sp. at our stool bank identified 2 donors with prior negative microscopies but positive polymerase chain reactions (PCRs). Potential transmission of Blastocystis sp. to patients was assessed on 16 fecal patient samples,

Abstract:

Blastocystis is one of the most common protozoa found in the human gut and are genetically diverse and widely distributed around the world. Nonspecific and inconsistent symptoms have been associated with this protozoon; thus, its clinical importance remains controversial. Our aim was to estimate the relative frequency of Blastocystis subtypes 1, 2, and 3, which are the predominant subtypes reported in South America, based on conserved regions of SSU rDNA sequences and determine the factors associated with them. A total of 116 Blastocystis-positive stool samples were processed using conventiona

Abstract:

Blastocystis hominis is a unicellular organism found commonly in the intestinal tract of humans and many other animals. Very little is known of the basic biology of the organism, and controversy surrounds its taxonomy and pathogenicity. There morphological forms (vacuolar, granular, and ameboid) have been recognized, but recent studies have revealed several additional forms (cyst, avacuolar, and multivacuolar). The biochemistry of the organism has not been studied to any extent, and organelles and structures of unknown function and composition are present in the cells. Several life cycles have

Abstract:

Blastocystis is an enteric microorganism commonly found in humans and animals worldwide. Its pathogenic role in humans and transmission patterns has not been fully explained. However, nine subtypes (ST1–8, ST12) are considered as potentially zoonotic. Studies from various regions of the world show that pigs are mainly infected with ST5. Although pigs are important farmed animals in Poland, the question of Blastocystis infection in these animals has not yet been investigated. Herein, 149 pig stool samples from 10 Polish pig farms were analyzed using sequence-tagged-site PCR and barcode region s
