OBJECTIVE To describe the frequency and antiparasitic in vitro susceptibility of Blastocystis hominis in patients admitted to theHospital Regional Lambayeque, Peru. MATERIAL AND METHODS A cross-sectional study was conducted from January to August 2015 at 313 patients of all ages. B. hominis detection was performed on serial fecal samples by direct microscopic examination and microculture in m...

BACKGROUND AND PURPOSE Blastocystis hominis has not been reported as an endemic disease in Taiwan, but high prevalence rates have been found among immigrants. Due to the increasing number of immigrants in Taiwan, B. hominis may become a public health problem in Taiwan. This study was performed to determine the prevalence of B. hominis among immigrant populations. METHODS Stool examination dat...

On clinical and prophylactic indications, 7905 patients were parasitologically examined, and Blastocystis hominis was detected in 273 (3.4%) of them. Detailed investigations were carried out in 82 of the infected patients (19 males and 63 females), divided into two groups: individuals with clinical symptoms and asymptomatic carriers. A correlation was found between the number of parasites detec...

Cultivation of luminal protistan parasites has a long history. In this review we discuss the methods and media that are most widely used for the establishment and maintenance of the following organisms in culture: Entamoeba histolytica, Giardia intestinalis, Trichomonas vaginalis, Dientamoeba fragilis, Blastocystis hominis, and Balantidium coli. While cultivation is of limited importance in the...

To evaluate the prevalence of Blastocystis hominis and its clinical relevance, 169 preschool children from the 'Los Coquitos' nursery school living in Bolivar City, Venezuela, were studied. Stool samples were obtained and examined by direct microscopic examination, and the Faust and Willis concentration techniques. Some 72 of the children had intestinal parasites, of whom 32 (29.09%) had B. hom...

Irritable bowel syndrome (IBS) is a functional bowel disorder in which abdominal pain is associated with a defect or a change in bowel habits. Subtle inflammation, especially after infectious enteritis, has been sometimes suspected as one mechanism of pathogenesis. This research was performed (1) to evaluate the prevalence of parasitic infections and (2) the possible association of IBS and para...

Among 56 foodhandlers annually examined for parasitologic infection from 1985 to 1990, 27 (48%) had at least one positive examination. One foodhandler was positive twice, one three times, and two four times. Three harbored two types of parasites. Thus, the total number of positive examinations was 39 (Table). Among these 39 positive results, 31 involved protozoa with direct transmission: Blasto...
