BACKGROUND: Intestinal parasitic infections remain prevalent and constitute a public health problem in certain rural areas of Thailand. Village health volunteers (VHVs), who are members of a Thai healthcare alliance, function as key providers of health prevention measures, disease control, and health education and share national health promotion campaigns with community members. This study is aimed at evaluating the prevalence, intensity, and risk factors for intestinal parasitic infection in VHVs in order to design community awareness and health education campaigns for the target population...

Strongyloides stercoralis is a gastrointestinal parasitic nematode with a life cycle that includes free-living and parasitic forms. For both clinical (diagnostic) and environmental evaluation, it is important that we can detect Strongyloides spp. in both human and non-human fecal samples. Real-time PCR is the most feasible method for detecting the parasite in both clinical and environmental samples that have been preserved. However, one of the biggest challenges with PCR detection is DNA degradation during the postage time from rural and remote areas to the laboratory...

Heretofore, transgenesis in the parasitic nematode genus Strongyloides has relied on microinjecting transgene constructs into gonadal syncytia of free-living females. We now report transgenesis in Strongyloides stercoralis by microinjecting constructs into the syncytial testes of free-living males. Crosses of individual males microinjected with a construct encoding GFP with cohorts of 12 non-injected females produced a mean of 7.28±2.09 transgenic progeny. Progeny of males and females microinjected with distinct reporter constructs comprised 2...

PURPOSE OF REVIEW: Strongyloidiasis is a parasitic infection affecting millions of people worldwide. Complications of infection are strongly associated with alcoholism, immunosuppression, and organ transplantation. Delayed diagnosis results in hyperinfection syndrome and disseminated strongyloidiasis leading to mortality rates approaching 80%. Early detection, and prevention of infection and transmission are key to diminish this illness. RECENT FINDINGS: In this review, we cover the basic concepts in immunity, immunosuppression, and disorder necessary for understanding the infectious syndromes associated with Strongyloides stercoralis infection...

Autoinfection caused by Strongyloides stercoralis frequently becomes a life-long disease unless it is effectively treated. There is overlapping histomorphology between Strongyloides colitis and inflammatory bowel disease; a low index of suspicion can lead to misdiagnosis and fatal consequences. We present a case of Strongyloides colitis mimicking the clinical and pathologic features of inflammatory bowel disease. A 64-year-old female presented to the emergency department with a four-day history of abdominal pain, diarrhea, and hematochezia...

Most studies evaluating epidemiologic relationships between helminths and HIV have been conducted in the pre-ART era, and evidence of the impact of helminth infections on HIV disease progression remains conflicting. Less is known about helminth infection and clinical outcomes in HIV-infected adults receiving antiretroviral therapy (ART). We sampled HIV-infected adults for eight gastrointestinal parasites and correlated parasitic infection with demographic predictors, and clinical and immunologic outcomes. Contrasting with previous studies, we measured parasitic infection with a quantitative, highly sensitive and specific polymerase chain reaction (PCR) method...

The parasitic nematodes, Strongyloides stercoralis and Strongyloides fuelleborni, can infect humans and non-human primates. We amplified and sequenced a portion of the 18S ribosomal RNA gene (rRNA) and of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene of Strongyloides from humans in the study area in Thailand, where people have frequent contact with long-tailed macaques. Fresh stool samples were obtained from 213 people and were examined using the agar plate culture method. The overall prevalence of Strongyloides infection was 8...

Strongyloides stercoralis can cause severe infection both in humans and dogs. Coproparasitological examination has low sensitivity for the diagnosis of this parasite; hence, different diagnostic techniques have been implemented. However, serology and molecular methods have been assessed almost exclusively in humans. In this study, two serologic assays and a real-time PCR (RT-PCR), routinely used for the diagnosis of strongyloidiasis in humans, have been tested for the diagnosis in dogs. Five dogs living in the same kennel in Bari, southern Italy, were diagnosed with S...

Human intestinal sarcocystosis (HIS), caused by Sarcocystis species, is acquired by eating undercooked meat from sarcocyst-containing cattle (S. hominis, S. heydorni) and pigs (S. suihominis). We report on the detection of human intestinal Sarcocystis infections in a cross-sectional survey of Strongyloides stercoralis in early 2014, in Rovieng District, Preah Vihear Province, northern Cambodia. Among 1081 participants, 108 (10.0%) were diagnosed with Sarcocystis spp. oocysts in stool samples. Males had a significantly higher risk of infection than females (OR: 1...

Chronic strongyloidiasis is an infection of the tropical regions, caused by the nematode Strongyloides stercoralis. In the United States, patients are typically immigrants. The very long asymptomatic phase followed by the clinical presentation of the disease mimics asthma, chronic obstructive pulmonary disease (COPD), or inflammatory bowel disease (IBD) as in this case report. The inconsistency of eosinophilia and the low sensitivity of microscopic stool examination make chronic strongyloidiasis a disease that is frequently misdiagnosed in the United States...

BACKGROUND: Strongyloidiasis is a chronic parasitic infection caused by Strongyloides stercoralis. Severe cases such as, hyperinfection syndrome (HS) and disseminated strongyloidiasis (DS), can involve pulmonary manifestations. These manifestations frequently aid the diagnosis of strongyloidiasis. Here, we present the pulmonary manifestations and radiological findings of severe strongyloidiasis. METHODS: From January 2004 to December 2014, all patients diagnosed with severe strongyloidiasis at the University of the Ryukyus Hospital or affiliated hospitals in Okinawa, Japan, were included in this retrospective study...

BACKGROUND / OBJECTIVES: Helminth infections are known to influence T cell responses in latent tuberculosis (LTBI). Whether helminth infections also modulate B cell responses in helminth-tuberculosis co-infection is not known. METHODS: We assessed Mycobacterium tuberculosis (Mtb)-antigen specific IgM and IgG levels, circulating levels of the B cell growth factors, BAFF and APRIL and the absolute numbers of the various B cell subsets in individuals with LTBI, LTBI with coincident Strongyloides stercoralis (Ss) infection (LTBI/Ss) and in those with Ss infection alone (Ss)...

INTRODUCTION: Cryptosporidium species is the most common opportunistic enteric parasite encountered in the immunocompromised patients. Considering the need to diagnose them early relies mostly on rapid tests such as antigen detection by immunochromatographic test (ICT), ELISA, and microscopy. However, the sensitivity and specificity varies with different methods and different kits used. This study was conducted to determine the intestinal parasitic profile in immunocompromised patients and to assess the diagnostic accuracy of the ICT using ImmunoCard STAT kit in detecting Cryptosporidium spp...

Strongyloides stercoralis is an intestinal helminth that infects people worldwide. Hyperinfection or disseminated human strongyloidiasis can involve vital organs, leading to lethal outcomes. We analyzed immunoproteomics of antigenic spots, derived from S. stercoralis third-stage larvae and reacted with human strongyloidiasis sera, by two-dimensional gel electrophoresis and immunoblotting. Of 26 excised antigenic spots analyzed by liquid chromatography-electrospray ionization-tandem mass spectrometry, 20 proteins were identified...

BACKGROUND: The German Military Medical Service contributed to the medical screening of unaccompanied minor refugees (UMRs) coming to Germany in 2014 and 2015. In this study, a broad range of diagnostic procedures was applied to identify microorganisms with clinical or public health significance. Previously, those tests had only been used to screen soldiers returning from tropical deployments. This instance is the first time the approach has been studied in a humanitarian context. METHODS: The offered screenings included blood cell counts, hepatitis B serology and microscopy of the stool to look for protozoa and worm eggs as well as PCR from stool samples targeting pathogenic bacteria, protozoa and helminths...
