Forty-one wild sheep (Ovis ammon orintalis) from Kabodan Island of National Park of Urmia Lake (North-West of Iran), were examined during a period of six months from October 2002 to March 2003, for helminthes and coccidian infection. The numbers of oocyst and eggs per gram of faeces (OPG & EPG) were determined by the centrifuge flotation technique using saturated sugar solution. The rate of inf...

BACKGROUND Immunity that reduces worm fecundity and, in turn, reduces morbidity is proposed for Schistosoma haematobium, a parasite of major public health importance. Mathematical models of epidemiological trends suggest that antifecundity immunity is dependent on antibody responses to adult-worm-derived antigen. METHODS For a Malian cohort (age, 5-29 years) residing in high-transmission fish...

As guinea-worm infection of the upper extremities, and especially of the eye, is rare, the following notes on my own personal case history may be of interest to the medical profession in this country. As is well known, the disease is contracted by drinking or bathing in water containing infected Cyclops, and where the same source of drinking and bathing water is used by several members of a fam...

BACKGROUND The latest estimates indicate that more than 2 billion people worldwide are infected by Soil-Transmitted Helminths (STH). The burden of STH infection is mainly attributed to the chronic effect on health and quality of life of those infected. It is also contributed to micronutrient deficiencies such as iron-deficiency anaemia. The prevalence of worm infection in Public Primary School ...

Abstract Ascariasis is a common helminthic infection, particularly in the tropical countries. We describe case of eosinophilia who underwent coronary artery bypass graft (CABG) surgery. Postoperatively, he was found to have ascaris lumbricoides oral cavity. Timely detection and removal worm prevented possible complications such as airway obstruction, bronchospasm, lung collapse, or intestinal o...

dioctophyma renale infection is found in a wide range of mammalian species, typically in temperate areas of the world. here, we report for the first time, the parasitism of a domestic dog by d. renale in hamedan, iran, a mountainous cold region, lacking significant amounts of rainfall, high humidity and temperature. a 2.5 yr old male mixed breed dog was presented with a two months history of pr...

OBJECTIVE To report that screw-in type pacing leads can be removed by screw retraction even after a significant anchoring period. PATIENT A 78-year-old woman who visited our hospital for skin erosion over a pacemaker that had been implanted 3 years previously and had migrated from the subclavicular area to the axilla. METHODS Culture revealed a local staphylococcus infection. We placed a ne...

BACKGROUND & AIMS Hyperplasia of mucin-secreting intestinal goblet cells accompanies a number of enteric infections, including infections by nematode parasites. Nevertheless, the precise role of mucins in host defense in nematode infection is not known. We investigated the role of the mucin (Muc2) in worm expulsion and host immunity in a model of nematode infection. METHODS Resistant (BALB/c,...

ERNST Caspari was the first researcher to use methods of developmental biology to analyze the action of a gene. By transplanting larval tissue between the wild type and a red-eyed mutant of the moth, Ephestia, he demonstrated that wild-type larvae produce a diffusible ‘‘substance’’ that is lacking in the mutant and is necessary for the development of eye pigmentation. Further characterization o...

BACKGROUND Much of our current understanding of the epidemiology of Ascaris lumbricoides infections in humans has been acquired by analyzing worm count data. These data are collected by treating infected individuals with anthelmintics so that worms are expelled intact from the gastrointestinal tract. Analysis of such data established that individuals are predisposed to infection with few or man...
