The use of morphometric characters to discriminate populations of Heterorhabditis bacteriophora (Nematoda: Heterorhabditidae).

In a survey of entomopathogenic nematodes (EPNs) in the northwest of Iran, eleven isolates of Heterorhabditis bacteriophora were recovered mainly from the soil samples of apple orchards. The isolates were identified morphologically and molecularly. To unravel intraspecific variation, morphometric characters of different life stages, including hermaphrodite, female, male and infective juvenile (IJ), were evaluated to see efficiencies in discrimination of H.

Complete resolution of obstructive colonic amebic pseudotumor with conservative treatment: A case report and literature review.

Introduction: Entamoeba histolytica is a well-known cause of infectious colitis, it has a worldwide distribution. Presentation ranges from mild diarrhea to occasionally frank dysentery and may spread to involve extra intestinal sites such as the liver, lung, and other organs, in the form of amebic abscesses.

Case Presentation: Herein, we report a case of amebic pseudotumor wherein the diagnosis was revealed after 2 months of diarrhea.

Surgical treatment of gastric outlet obstruction from a large trichobezoar: A case report.

Introduction: Bezoars are concretions of foreign indigestible material accumulating in the gastrointestinal tract leading to intraluminal mass formation that impairs the gastrointestinal motility and can lead to gastric obstruction of the small or the large bowel. There are different types of bezoars, named according to the material they are made of. These include phytobezoar, lactobezoar, pharmacobezoar, trichobezoar, and polybezoar.

Single-institution experience of medical students' bacterial colonization during training.

Background: Medical students are often potential vectors for resistant bacteria to their entourage. We therefore conducted this study to evaluate the variation of medical students' multiple drug resistant bacterial flora throughout their medical training.

Methods: We performed a cross-sectional study enrolling medical students of the 2016 academic year from the Saint-Joseph University - Faculty of Medicine, Lebanon.
