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)
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)
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)
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)
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 Diagnosis of Chagas disease in its latent and chronic phase is difficult because of the low parasitemia levels. Therefore, serological and molecular techniques are necessary to achieve an appropriate diagnosis. OBJECTIVE The polymerase chain reaction based on the amplification of the SIRE element inserted into H2A encoding genes was compared(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)
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)
objective To determine the prevalence and risk factors associated with Chagas disease in pregnant women in an endemic area of Santander, Colombia. methods Cross-sectional study included 23 municipalities of Santander, Colombia. Serological IFAT and ELISA tests were undertaken to detect IgG anti-Trypanosoma cruzi. A questionnaire was conducted for assessing(More)
