Ascariasis is one of the most common helminthic diseases on earth. Abdominal ultrasonography is usually used for the diagnosis of biliary ascariasis in spite of diagnosis of this infestation is not easy. Two ultrasonographic image of jejunal ascariasis is added to depict clinical situation.

The migration of larvae of Ascaris lumbricoides from the intestine through the lungs and bronchial tree into the oesophagus and back into the intestine is a well-known feature of the life cycle of this nematode. The passage through the lungs remains often symptomless, but, in an investigation on experimental infection in man, Takata (1951) found cough in 71-4% of those infected with human ascar...

examination of faecal samples of 6,430 school children aged between 2 and 20 years, for gastrointestinal parasites using sedimentation and kato smear techniques was carried out in benin city, nigeria between january 1997 and december 1998. four thousand two hundred and thirty six (65.8%) were infected. three species of protozoa and 8 species of helminths were recorded as follows: entamoeba hist...

Parasitic infestations of the hepatic biliary tree most commonly involve Ascaris lum− bricoides, which infects an estimated 25 % of the world s population [1]. These infec− tions are increasing in the developed countries due to world travel and popula− tion migrations. Individuals may be asymptomatic. When symptoms occur, they include pulmonary and hypersensi− tivity manifestations, and intesti...

Ultrastructural observations of the in utero sperm of Ascaris lumbricoides reveal that it consists of a relatively clear, ameboid anterior region and a conical posterior region containing numerous surface membrane specializations, dense mitochondria, a lipid-like refringent body of variable size, and a dense nucleus which lacks an apparent nuclear envelope. No acrosomal complex was observed. Ps...

a preponderance over Malabar in this respect. The unhygienic method of disposal of the nightsoil and the excreta, the shallowness of most of its wells, the dirty habit of many of its folk, its peculiar climate and the vegetarian life of most of its people are among the most potent contributions towards the exuberant propagation of these human foes. Picture to yourself a compound with damp soil,...

BACKGROUND Conventional diagnostic methods for human ascariasis are based on the detection of Ascaris lumbricoides eggs in stool samples. However, studies of ascariasis in pigs have shown that the prevalence and the number of eggs detected in the stool do not correlate well with exposure of the herd to the parasite. On the other hand, an ELISA test measuring antibodies to Ascaris suum haemoglob...

PURPOSE The aim of this study is to present patients, to discuss causes of morbidity and mortality, and to ascertain prognostic indexes and therapeutic options influencing outcome of patients with intestinal obstruction caused by Ascaris lumbricoides. MATERIALS AND METHODS During the past 20 years, between 1975 and 1995, a total of 17 patients with intestinal obstruction attributable to A. lu...

A. lumbricoides is the largest of the common nematode parasites of man and has been associated with intestinal pathology, respiratory symptoms and malnutrition in children from endemic areas. Current anthelmintic treatments have proven to be safe. However, a reduced efficacy of single dose drugs has been reported. In veterinary practice, anthelmintic drug resistance is an irreversible problem. ...
