myiasis is the infection caused by a variety of dipterous (fly) larvae in vertebrate’s tissue (man and domestic or wild animals). species of gasterophilus are obligate parasite of horses, donkeys, zebras, elephants and rhinoceroses. there are records worldwide, but mostly, in tropical and subtropical regions. this case report describes a type of gastric myiasis caused by g. intestinalis in an o...

Modern research indicates a possible synergistic effect of bacterial-protozoal infestations in the pathology upper gastrointestinal tract, among which special attention is paid to problem giardiasis. Other parasitic agents, particular Blastocystis spp, are also gaining some significance. The aim study prevalence H. pylori and protozoal chronic gastroduodenal diseases influence on indicators enz...

Pneumatosis cystoides intestinalis is a rare and often presents nonspecific symptoms. In this case, CT imaging revealed air collection within the wall of the ileum, which was more clearly defined using the lung window setting. When we consider pneumatosis cystoides intestinalis, we should evaluate CT using the lung window setting.

Pneumatosis Intestinalis is defined as the infiltration of gas into the bowel wall. It is a radiological and intra-operative finding of varying aetiology which varies from benign to life threatening conditions. We describe here a case of a 67 year old woman who presented with diffuse abdominal pain and was found to have Pneumatosis Intestinalis.

The ribosomal DNA internal transcribed spacer sequences of 13 unrelated Encephalitozoon intestinalis isolates obtained from human immunodeficiency virus (HIV)-infected patients with intestinal microsporidiosis were analyzed by gene amplification and DNA sequencing. Among these isolates, we found only one genetic lineage which suggests that E. intestinalis may have a clonal distribution in HIV-i...

Pneumoperitoneum in the presence of acute abdominal pain is well recognised as an indication for laparotomy. We present a case of acute abdominal pain in the presence of an incidental pneumoperitoneum secondary to the rupture of pneumatosis intestinalis. We will discuss the importance of clinical context in the diagnosis and management of pneumoperitoneum and pneumatosis intestinalis.

We applied independent species concepts to clarify the phylogeographic structure of the ascidian Ciona intestinalis, a powerful model system in chordate biology and for comparative genomic studies. Intensive research with this marine invertebrate is based on the assumption that natural populations globally belong to a single species. Therefore, understanding the true taxonomic classification ma...

Giardia intestinalis and Hexamita inflata are microaerophilic protozoa which rely on fermentative metabolism for energy generation. These organisms have developed a number of antioxidant defence strategies to cope with elevated O(2) tensions which are inimical to survival. In this study, the ability of pyruvate, a central component of their energy metabolism, to act as a physiological antioxida...

Giardia intestinalis is a primitive microaerophilic protozoan parasite which colonises the upper intestine of humans. Despite the evolutionary and medical significance of this organism, its physiology is very poorly understood. In this study we have used a novel flow cytometric technique to make quantitative measurements of the electrical potential across the plasma membrane of G. intestinalis ...

the lernaea parasite was reported in alburnus hohenackeri kessler, 1870, collected from the char-nimeh (or chahnimeh) lake, eastern iran. three fishes were infected with l. intestinalis having 3 to 22 parasites increasing with fish size. the maximum and minimum of parasite lengths were 138.02 mm and 24.54 mm respectively. the prevalence, mean intensity and abundance of infection by plerocercoid...
