Blastocystis is a common enteric protist colonizing probably more than 1 billion people along with a large variety of non-human hosts. This protist has been linked to symptoms and diseases such as abdominal pain, constipation, diarrhea, flatulence and irritable bowel syndrome (IBS). Remarkable genetic diversity has been observed, leading to the subdivision(More)
Chagas disease is an endemic disease of the American continent caused by Trypanosoma cruzi and divided into six discrete typing units (TcI - TcVI). Nearly 10 million people harbour the infection representing a serious issue in public health. Epidemiological surveillance allowed us to detect a bat-related T. cruzi genotype (henceforth named TcBat) in a(More)
BACKGROUND Trypanosoma cruzi, the causative agent of Chagas disease, displays significant genetic variability revealed by six Discrete Typing Units (TcI-TcVI). In this pathology, oral transmission represents an emerging epidemiological scenario where different outbreaks associated to food/beverages consumption have been reported in Argentina, Bolivia,(More)
Scientific productivity of middle income countries correlates stronger with present and future wealth than indices reflecting its financial, social, economic or technological sophistication. We identify the contribution of the relative productivity of different scientific disciplines in predicting the future economic growth of a nation. Results show that(More)
INTRODUCTION In Colombia, reported cases of acute Chagas disease are sporadic. OBJECTIVE Ten cases were described that had been reported to the Parasitology Laboratory of the Colombian National Health Institute between December 2002 and November 2005. MATERIALS AND METHODS Information from clinical records, epidemiological report forms, laboratory and(More)
Knowledge of the prevalence and risk factors associated with maternal infection is the first step to develop a surveillance system for congenital transmission of Chagas disease. We conducted a cross-sectional study in Casanare, a disease-endemic area in Colombia. A total of 982 patients were enrolled in the study. A global prevalence of Trypanosoma cruzi(More)
INTRODUCTION The diagnosis of Chagas' disease is essential to provide early treatment and improve patients' prognosis . The discriminatory efficiency of the serological tests varies according to the disease prevalence and the test- antigen used . OBJECTIVE To evaluate the discriminatory efficiency of the commercial kit Chagas ( Trypanosoma cruzi )(More)
INTRODUCTION The diagnosis of chronic Trypanosoma cruzi infection is supported by serological tests whose reproducibility has not been well documented. OBJECTIVE To evaluate the reproducibility of the serological tests ELISA, IFAT and IHAT for the diagnosis of T. cruzi infection in pregnant women in an endemic zone in Santander. MATERIALS AND METHODS(More)
Opportunistic intestinal parasites are a common cause of diarrhea in HIV-infected patients. To determine the prevalence of microsporidia and other opportunistic parasites infecting HIV patients in Bogotá, Colombia, 115 patients were examined for these infections during the year 2001. The institution and the sample percent from each are as follows: Santa(More)
BACKGROUND Chagas disease is an anthropozoonosis caused by Trypanosoma cruzi. Two drugs are currently used for the etiological treatment of the disease: Nifurtimox (Lampit) and Benznidazole. This study presents a quasi-experimental trial (non-control group) of sixty-two patients who were treated for Chagas disease with Nifurtimox (Lampit), and were then(More)
