Background: Giardia and Cryptosporidium are both enteric pathogens causing diarrhea with no reliable method for their diagnosis. The aim of our study was to evaluate the diagnostic performance of a rapid immunochromatographic (IC) ImmunoCard STAT! Crypt/Giardia assay (Meridian Bioscience, Inc.) in comparison to composite reference standard (CRS) of both wet mount microscopy and ELISA copro-anti...

Changes in urinary porphyrin excretion may be the result of hereditary causes and/or from environmental or occupational exposure. The objective of this study was to measure the amount of some porphyrins in spot urine samples obtained from volunteers randomly selected from a healthy adult population of São Paulo with a sensitive HPLC method and to estimate normal ranges for a non-exposed populat...

OBJECTIVES (1) To investigate the response to a serum antigen-detecting ELISA for cysticercosis and a stool coproantigen test for taeniasis in two rural communities (mountainous and coastal areas) and one group of (peri-)urban factory workers; and (2) to examine clinical features of human cysticercosis in northern Vietnam. METHODS Villagers and factory workers and their families were informed...

BACKGROUND Emergence of human fascioliasis prompted a worldwide control initiative including a pilot study in a few countries. Two hyperendemic areas were chosen: Huacullani, Northern Altiplano, Bolivia, representing the Altiplanic transmission pattern with high prevalences and intensities; Cajamarca valley, Peru, representing the valley pattern with high prevalences but low intensities. Coprol...

The study was conducted to compare the specificity of immunological diagnostic methods used for the diagnosis of Cryptosporidium species capable of causing life-threatening infection in both immunosuppressed and immunocompetent patients. For the detection of Cryptosporidium species in 79 animals with diarrhoea, we used three Copro-antigen tests: RIDASCREEN®Cryptosporidium test, Cryptosporidium ...

The clinical and economic importance of fasciolosis has been recognised for centuries, yet diagnostic tests available for cattle are far from perfect. Test evaluation has mainly been carried out using gold standard approaches or under experimental settings, the limitations of which are well known. In this study, a Bayesian no gold standard approach was used to estimate the diagnostic sensitivit...

BACKGROUND Cystic echinococcosis is highly prevalent in northwest China. A cost-effective, easy to operate diagnostic tool with high sensitivity and specificity would greatly facilitate the monitoring of Echinococcus infections in canine definitive hosts. METHODS The primers used in the LAMP assay were based on the mitochondrial nad5 gene of E. granulosus sensu stricto (E. granulosus s.s., or...

Calves born to multiparous Holstein cows fed during the last 30 d of pregnancy 2 different cobalt sources [cobalt glucoheptonate (CoPro) or pectin (CoPectin)], folic acid (FOA), and rumen-protected methionine (RPM) were used study neonatal immune responses after ex vivo lipopolysaccharide (LPS) challenge. Groups (n = 12 calves/group) CoPro, FOA+CoPro, FOA+CoPectin, FOA+CoPectin+RPM. weighed at ...

The detection of Fasciola antigen in serum or stool could be more valuable in diagnosis, hence early treatment before irreparable damage. In this study, fresh adult Fasciola gigantica worms were collected, then incubation in culture medium and collected medium was used to extract crude excretory-secretory (E/S) antigen. E/S was used to immunize rabbits to raise specific antibodies against Fasci...
