increased sampling reveals novel lineages of entamoeba: consequences of genetic diversity and host specificity for taxonomy and molecular expand the representation for phylogenetic analysis, ten additional complete entamoeba small-subunit rrna gene sequences were obtained from humans, non-human primates, cattle and a tortoise. for some novel sequences no corresponding morphological data were available, and we suggest that these organisms should be referred to as ribosomal lineages (rl) rather than being assigned species names at present. to investigate genetic diversity and host specificity of selected entamoeba species, a tota ...201121295520
[frequency of intestinal parasites among administrators and workers in sanitary and non-sanitary institutions.]objective: transmission of parasites generally occurs through fecal-oral means directly from human to human or through receiving eggs and cysts by means of nourishment. the aim of the study was to investigate the frequency of intestinal parasites among administrators and workers in sanitary and non-sanitary institutions. methods: stool specimens were examined using native-lugol, trichrome and acid-fast stains methods. results: 23.7% of the 2443 fecal specimens were found to be positive. the freq ...201121618189

molecular detection of eukaryotes in a single human stool sample from senegal.microbial eukaryotes represent an important component of the human gut microbiome, with different beneficial or harmful roles; some species are commensal or mutualistic, whereas others are opportunistic or parasitic. the diversity of eukaryotes inhabiting humans remains relatively unexplored because of either the low abundance of these organisms in human gut or because they have received limited attention from a whole-community perspective.201222808282
differential diagnosis of entamoeba spp. in clinical stool samples using sybr green real-time polymerase chain reaction.amoebiasis, a disease caused by entamoeba histolytica, is usually diagnosed by microscopic examination, which does not differentiate the morphologically identical species of the e. histolytica/e. dispar complex. furthermore, morphologically similar species such as entamoeba hartmanni contribute to misidentification. therefore, there is a need for more sensitive and specific methods. this study standardized a multiplex real-time pcr system for e. histolytica and e. dispar and a single real-time p ...201424693242
frequency of amoebiasis and other intestinal parasitoses in a settlement in ilhéus city, state of bahia, brazil.this study evaluated the frequency of intestinal parasites, emphasizing the identification and differentiation of entamoeba spp.201424553799
diversity and prevalence of gastrointestinal parasites in seven non-human primates of the taï national park, côte d'ivoire.parasites and infectious diseases are well-known threats to primate populations. the main objective of this study was to provide baseline data on fecal parasites in the cercopithecid monkeys inhabiting côte d'ivoire's taï national park. seven of eight cercopithecid species present in the park were sampled: cercopithecus diana, cercopithecus campbelli, cercopithecus petaurista, procolobus badius, procolobus verus, colobus polykomos, and cercocebus atys. we collected 3142 monkey stool samples betw ...201525619957
intestinal parasites in diabetic patients in sohag university hospitals, egypt.intestinal parasites usually create benign diseases, though they may induce complications with high morbidity and mortality to the immunocompromised, including diabetic patients. the study detected the prevalence of intestinal parasitic infections in diabetic patients, comparing to non-diabetic controls and other parameters. a total of 100 fecal samples were collected from diabetic patients at the outpatient clinic of sohag university hospitals and another 100 from cross matched controls. the sa ...201526485865
molecular identification of entamoeba species in savanna woodland chimpanzees (pan troglodytes schweinfurthii).to address the molecular diversity and occurrence of pathogenic species of the genus entamoeba spp. in wild non-human primates (nhp) we conducted molecular-phylogenetic analyses on entamoeba from wild chimpanzees living in the issa valley, tanzania. we compared the sensitivity of molecular [using a genus-specific polymerase chain reaction (pcr)] and coproscopic detection (merthiolate-iodine-formaldehyde concentration) of entamoeba spp. we identified entamoeba spp. in 72 chimpanzee fecal samples ...201626935395
frequency and molecular characterisation of entamoeba histolytica, entamoeba dispar, entamoeba moshkovskii, and entamoeba hartmanni in the context of water scarcity in northeastern brazil.this study aimed to estimate the frequency, associated factors, and molecular characterisation of entamoeba histolytica, entamoeba dispar, entamoeba moshkovskii, andentamoeba hartmanni infections. we performed a survey (n = 213 subjects) to obtain parasitological, sanitation, and sociodemographic data. faecal samples were processed through flotation and centrifugation methods.e. histolytica, e. dispar, e. moshkovskii, and e. hartmanni were identified by nested-polymerase chain reaction (pcr). th ...201626841049
a decade of intestinal protozoan epidemiology among settled immigrants in qatar.the world health organization estimates that about 3.5 billion people worldwide are affected by intestinal parasitic infections. reports have already emphasized the role of immigrants in outbreaks of parasitic diseases in industrialized countries. with the mass influx of immigrants to qatar, patent intestinal parasitic infections have been observed. herein, the prevalence of intestinal protozoan infections was analysed in 29,286 records of subjects referred for stool examination at the hamad med ...201627496143
