The study of the cytopathic effects of Blastocystis sp., ST1-3 and 6 isolated from subjects referred to medical laboratories in HT29 cell line
Background and Aim: Blastocystis sp., is one of the most common intestinal protozoan parasites found in both human and animal fecal samples. The pathogenicity and cytopathic effects of subtypes ST1-3 and 6 of Blastocystis sp., on gastrointestinal cell line are not clear. This study aimed to investigated intra-subtype variations on the apoptosis and cytopathic effects on HT-29 cell line in 2019,...
متن کاملDiagnosis and subtype analysis of Blastocystis sp. in 442 patients in a hospital setting in the Netherlands
BACKGROUND Blastocystis sp. are among the most commonly observed intestinal parasites in routine clinical parasitology. Blastocystis in humans consists of at least 9 genetic subtypes. Different subtypes of Blastocystis may be associated with differences in pathogenicity and symptomatology. METHODS Advanced microscopy on two samples and sequence-confirmed PCR on a third sample from the same in...
متن کاملIntestinal parasite infections in a rural community of Rio de Janeiro (Brazil): Prevalence and genetic diversity of Blastocystis subtypes
BACKGROUND Intestinal parasitic infections are considered a serious public health problem and widely distributed worldwide, mainly in urban and rural environments of tropical and subtropical countries. Globally, soil-transmitted helminths and protozoa are the most common intestinal parasites. Blastocystis sp. is a highly prevalent suspected pathogenic protozoan, and considered an unusual protis...
متن کاملSubtypes Distribution and Frequency of Blastocystis sp. Isolated from Diarrheic and Non-diarrheic Patients
BACKGROUND Blastocystis is one of the most common parasites, reported from both human and animals. This parasite is more prevalent in regions with low levels of hygiene, close contact with animal and unsuitable disposal systems. The aim of the study was to subtype Blastocystis sp., isolated from diarrheic and non-diarrheic patients using sequencing of 18S ribosomal DNA. METHODS Totally, 300 s...
متن کاملBlastocystis Isolates from Patients with Irritable Bowel Syndrome and from Asymptomatic Carriers Exhibit Similar Parasitological Loads, but Significantly Different Generation Times and Genetic Variability across Multiple Subtypes
Blastocystis spp is a common intestinal parasite of humans and animals that has been associated to the etiology of irritable bowel syndrome (IBS); however, some studies have not found this association. Furthermore, many biological features of Blastocystis are little known. The objective of present study was to assess the generation times of Blastocystis cultures, from IBS patients and from asym...
