conclusions the results of the study showed a high prevalence of giardia lamblia and blastocystis hominis in rural areas compared to urban regions. therefore it is necessary to promote the public health awareness in the rural population, in order to reduce the frequency of parasitic infections. background nowadays, parasitic infections are a major health problem throughout the world, particular...

intestinal parasitic infections are still a healthy problem in many developing countries, although intestinal parasitic infection has reduced in recent years, it is still prevalent in many regions of iran. this study was carried out in order to determine fauna and prevalence of human intestinal parasites in patients referred to kashan reference laboratory in 2007-2011. totally 6348 persons (53%...

To further understand the epidemiology of enterotoxigenic Bacteroides fragilis (ETBF), 89 extraintestinal B. fragilis strains from Seoul, Korea, were examined for secretion of B. fragilis toxin (BFT) by the HT29/C1 biologic assay and for the B. fragilis toxin gene (bft) by colony blot hybridization and PCR. Complete agreement between the three techniques was found. Overall, 34 B. fragilis strai...

TO THE EDITOR—In their recent paper, Coyle et al [1] recommend metronidazole as the drug of choice for Blastocystis eradication. We have come across multiple cases where high-dose metronidazole treatment does not eliminate Blastocystis from the intestine. In fact, it appears that no single drug is capable of eradicating Blastocystis [2]. Here, we present an example of an intractable Blastocysti...

Reptiles can be on the diet of some bird species, and glass lizard Ophiodes fragilis seems to no exception. Although predation events are not easily recorded, in this work we document a new record by C. cristata upon O. fragilis. The event occurred November 2017 municipality Viçosa, state Minas Gerais, Brazil, helps fill gap trophic relationships between its predators.

Non-enterotoxigenic bacteria of the Bacteroides fragilis group and enterotoxigenic B. fragilis were identified from children with and without aqueous acute diarrhea. In this study, 170 stool samples from 96 children with and 74 without diarrhea were analyzed. Enterotoxin production and the toxin gene detection were detected by cytotoxicity assay on HT-29/C1 cells and by PCR, respectively. B. fr...

Factors affecting the susceptibility of Bacteroides fragilis subsp. fragilis to low temperature were examined. Predetermined numbers of cells were spread on agar media or suspended in enriched Trypticase soy broth and exposed to low temperature under both aerobic and anaerobic conditions. Exposure of 18-h growth of a freshly isolated B. fragilis strain to 4 degrees C aerobically or anaerobicall...
