The factors that influence the sediment stability and the transport of estuarine mudflats are not yet fully understood but knowledge of them is essential in coastal engineering applications and pollution ecology studies. The suggestion that variation in predictive models of sediment stability might be due to site-specific characteristics is investigated using data from four estuarine mudflats (...

In species introductions, non-native are often confronted with new niches occupied by more specialized natives, and for introduced parasites this conflict can be amplified because they also face novel hosts. Despite these obstacles, invasions of occur frequently, but the mechanisms that facilitate parasite invasion success only rarely explored. Here, we investigated how parasitic copepod Mytili...

Anaerobic Digestion (AD) is one of the most widely used methods in field sustainable bioenergy production from various feedstock. One such feedstock algae waste which has become an increasingly serious environmental problem. AD algal biomass hindered by presence resistant cell walls; hence a pretreatment step usually required to decompose wall structure. This study uses green (Enteromorpha) and...

We compared the performance of the BD Max enteric parasite panel to routine microscopy and an in-house PCR for the detection of Giardia intestinalis, Entamoeba histolytica, and Cryptosporidium spp. The enteric parasite panel showed good specificity for all targets and good sensitivity for E. histolytica and Cryptosporidium spp. Sensitivity for G. intestinalis with the BD Max enteric parasite pa...

In this study, nine organic sediment samples from a medieval archaeological site at Pineuilh, France, were examined for Giardia intestinalis using two commercially available immunological kits [enzyme-linked immuno sorbent and immunofluorescence (IFA) assays]. Both techniques detected G. intestinalis in one sample, dated to 1,000 Anno Domini. This is the first time IFA was successfully used to ...

INTRODUCTION Pneumatosis intestinalis is a condition characterized by the presence of submucosal or subserosal gas cysts in the wall of digestive tract. Pneumatosis intestinalis often remains asymptomatic in most cases but may clinically present in a benign form or less frequently in fulminant forms. Treatment for such conditions includes antibiotic therapy, diet therapy, oxygen therapy and sur...

Giardia intestinalis is a complex species divided into 7 assemblages (A - G). Two of them (A and B) are infective for both humans and animals. In cats four assemblages can occur: A, B, D, and F Assemblages A and B infect either cats, dogs and humans, assemblage D infects cats and dogs and assemblage F only cats. The purpose of this study was to determine the prevalence and genotypes of G. intes...

pneumatosis cystoides intestinalis (pci) is a rare condition charachterized by the presence of multiple gases filled cysts in the gastro intestinal tract. in this article we present three cases with different features, who at the end evaluation pci was diagnosed. the first patient present with rectorrhagia (submucosal pci). the second patient present with dyspepsia (subserosal intestinal pci) a...
