BACKGROUND: Exotic reptiles such as tortoises, have become increasingly common domestic pets worldwide and are known to host different gastrointestinal parasites. Some of these parasites bear zoonotic potential. In the present survey, we parasitologically examined tortoise faecal samples (n = 1005) from 19 different species held as pets in private German households and German zoological gardens. METHODS: Saline faecal smears were used to generate prevalence data for potentially health-compromising gastrointestinal parasites...

IL-9 is a cytokine with pleiotropic function that mediates allergic inflammation and immunity to intestinal helminth parasites. Accumulating evidence suggests that IL-9 acts via both, initiation and regulation of adaptive immune responses and direct activation of intestinal effector pathways. Here we use IL-9 receptor deficient mice on BALB/c and C57BL/6 genetic background to dissect effector and regulatory functions of IL-9 during infection with the parasitic nematode Strongyloides ratti. IL-9 receptor-deficient mice displayed increased intestinal parasite burden and prolonged infection irrespective of the genetic background of the mice...

Severe Strongyloides stercoralis , such as hyperinfection syndrome, carries a high mortality risk. Even with appropriate treatment, patients may experience infectious complications and failure of therapy. Currently, there are no Food and Drug Administration-approved parenteral therapies available for treatment in patients who develop gastrointestinal complications from hyperinfection, including small bowel obstruction. A veterinary form of ivermectin is available as a subcutaneous injection, although current literature in humans is limited...

BACKGROUND: Despite the considerable burden of helminth infections in developing countries and increasing international travel, little is known about the risks of infection for travelers. OBJECTIVE: We studied the attack and incidence rate of serology confirmed strongyloidiasis, filariasis, and toxocariasis among long-term travelers and associated factors. A second objective was to evaluate eosinophilia as a positive/negative predictive value (PPV/NPV) for a recent helminth infection...

BACKGROUND: The livestock industry plays a vital role in the economy of Nigeria. It serves as a major source of income and livelihood for majority of Nigerians who are rural settlers and contributes about 5.2% to the National Gross Domestic Product (GDP). Helminths however, cause economic losses due to reductions in milk production, weight gain, fertility and carcass quality. Zoonotic helminths of livestock origin cause health problems in humans. METHODS: Using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, the prevalence and distribution of helminths of veterinary and zoonotic importance in Nigerian ruminants were determined in a meta-analysis of data published between 1970 and 2016...

Strongyloides stercoralis (S. stercoralis) is an intestinal nematode endemic to tropical regions. An accelerated infection, known as a hyperinfection, occurs in immunocompromised patients, most commonly those treated chronically with glucocorticoids or those who have human T cell leukemia virus-1 (HTLV-1) infection. We describe a 67-year-old Hispanic female who presented with complaints of decreased oral intake and fatigue since three months. Hyponatremia on initial presentation was attributed to syndrome of inappropriate antidiuretic hormone (SIADH) secretion and managed with fluid restriction...

BACKGROUND: CD4+ and CD8+ T cells are central players in immunity to helminth infections. However, the role of T cell subsets in human helminth infections is not well understood. In addition, the common γc cytokines, IL-2, IL-4, IL-7, IL-9 and IL-15 play an important role in the maintenance of these CD4+ and CD8+ T cell subsets. METHODS: To examine the major T cell subsets and their association with the common γc cytokines, the absolute numbers of CD4+ and CD8+ naïve, central memory, effector memory and effector cells and the plasma levels of IL-2, IL-4, IL-7, IL-9 and IL-15 were measured in Strongyloides stercoralis (Ss) infected (INF, n = 60), helminth-uninfected (UN, n = 58) and in post treatment INF individuals...

Background: Mansonella perstans , Onchocerca volvulus and Strongyloides stercoralis are widespread helminth parasites in the tropics. Their distribution remains difficult to determine as it may change during national disease control programs and with regional mass drug administration (MDA). Epidemiological surveys are of importance to evaluate the geographical distribution of these helminth parasites and the diseases they may cause, however, up to date epidemiological evaluations on M...

The stone marten (Martes foina) is one of the most common species of marten in Europe. Due to increased urbanization and forest degradation, it is now often found in urban habitats, which increased the possibility of parasites transmission between wildlife-domestic animals and humans. Our preliminary study of this mustelid in Portugal, aimed to assess prevalence of helminths. Six helminth parasites were found (Crenosoma vulpis, Angiostrongylus sp., Toxocara sp., Toxascaris leonina, Ancylostomatidae and Strongyloides sp...

The objective of this study was to report a case of a hydronephrotic patient with Strongyloides stercoralis infection, with discharge of rhabditoid larva exclusively in urine. In 2013, a 72-yr-old, male patient, hypertensive, obese and diagnosed with hydronephrosis secondary to renal calculi, reported lumbar pain, polyuria, polaciuria and dysuria, as well as frequent urinary tract infections. The microscopic analysis of urine sediment showed the presence of S. stercoralis rabditoid larva. However, parasitological examinations by Baermann-Moraes, agar plate culture and spontaneous sedimentation, performed with 3 fecal samples on alternate days had negative results...

Strongyloides stercoralis (SS) can cause hyperinfection and disseminated infection in immunosuppressed individuals, with risk of mortality. We report the case of a cadaveric kidney transplant recipient who developed gastrointestinal symptoms and eosinophilia, approximately 3 months after transplantation. Stool examination and esophagogastroduodenoscopy with biopsies were positive for SS larvae. The patient was started on oral ivermectin and immunosuppression was reduced, but still the clinical picture got worse with metabolic ileus and respiratory symptoms, with the need for administration of subcutaneous ivermectin and combined therapy with albendazol...

Intestinal helminths are prevalent in individuals who live in rural areas of developing countries, where obesity, type 2 diabetes, and metabolic syndrome are rare. In the present study, we analyzed the modulation of the gut microbiota in mice infected with the helminth Strongyloides venezuelensis, and fed either a standard rodent chow diet or high-fat diet (HFD). To investigate the effects of the microbiota modulation on the metabolism, we analyzed the expression of tight-junction proteins present in the gut epithelium, inflammatory markers in the serum and tissue and quantified glucose tolerance and insulin sensitivity and resistance...

BACKGROUND: Lymphatic filariasis (LF) is a parasitic disease caused mainly by the Wuchereria bancrofti worm and that affects up to 120 million people worldwide. LF is the second cause of chronic global deformity, responsible for 15 million people with lymphedema (elephantiasis) and 25 million men with scrotal hydrocele. Its diagnosis is still associated with numerous difficulties, such as the sample collection periods (microfilaria nocturnal periodicity) and limited diagnostic kits. OBJECTIVES: The aim of this work was to evaluate two recombinant antigens (Wb14 and WbT) as part of an enzyme-linked immunosorbent assay (ELISA) based antibody capture tests for LF...

Strongyloides spp., gastrointestinal nematode parasites of humans and other animals, have genetically identical parasitic and free-living adult life cycle stages. This is an almost unique feature amongst nematodes and comparison of these two stages can provide insights into the genetic basis and evolution of Strongyloides nematode parasitism. Here, we present RNAseq data for S. venezuelensis, a parasite of rodents, and identify genes that are differentially expressed in parasitic and free-living life cycle stages...
