Hymenolepis diminuta is a cosmopolitan parasite of rats and mice which is very rare in humans. This study presents the case of a 3-year-old boy infected with Hymenolepis diminuta in Poland. The diagnosis was based on eggs found and their morphology in the patient's stool.

Dolichodorus miradvulvus n. sp. from Anubias nana Engler in Florida is described and illustrated. The female is characterized by deep grooves in the cuticle on the ventral surface just anterior and posterior to the vulva, and by transversely elongate pouches anterior and posterior to the vulva. Both sexes have a constricted area of the stylet shaft just anterior to the knobs, and on the male th...

Echinococcus granulosus is the most common tapeworm causing hydatid disease in humans. Its least-encountered complication is cutaneous fistulization. Omentoplasty, cyst, and fistulous tract drainage revealed successful in the management of this complication. Such intervention can be an alternative when conservative management fails, and a minimally aggressive procedure is required.

BACKGROUND Recent studies on geographic distribution of Echinococcus multilocularis in Europe show that it has a wider range than previously thought. It is unclear, however, if the wider distribution is due to its recent spreading or to a lack of previous data from the new areas. Italy, previously considered E. multilocularis-free, is now part of these new areas: infected foxes (the main defini...

UNLABELLED We report a rare case of a cardiac hydatid cyst that was incidentally found during routine work up for a redo-CABG and was picked up on echocardiography and confirmed by magnetic resonance imaging and, after successful removal, further confirmed by histopathology. The report emphasizes the importance of early and urgent surgery for such cardiac hydatid cysts whenever discovered to pr...

Information on the molecular basis of resistance and the evolution of resistance is crucial to an understanding of the appearance, spread, and distribution of resistance genes and of the mechanisms of host adaptation in natural populations. One potential important genetic constraint for the evolution of resistance is fitness cost associated with resistance. To determine whether host resistance ...
