Reuse of faecal sludge in agriculture has many potential benefits, but also poses risks to human health. To better understand the risks, Quantitative Microbial Risk Assessment (QMRA) was performed for three population groups Kampala, Uganda: wastewater and treatment plant workers; farmers using sludge; consumers sludge-fertilised vegetables. Two models were applied consumers, one based on patho...

a rare case of ascaris coming out through the anterior abdominal wall is reported here. a 40‑year‑old female had undergone dilatation and curettage by a quack. on the second day she presented with presented with features of peritonitis. she was explored. resection anastomosis of the ileum was done for multiple perforations of the ileum. patient developed a fistula in the anterior abdominal wall...

Human ascariasis is caused by infection with the common roundworm Ascaris lumbricoides, although the pig roundworm Ascaris suum has also been reported to infect humans and develop into the adult stage. To elucidate whether pig-derived Ascaris infects humans in Japan, 9 Ascaris isolates obtained from Japanese patients and a further 9 Ascaris isolates of pig origin were analyzed to determine thei...

In this study, Ascaris DNA was extracted and sequenced from a medieval archaeological sample in Korea. While Ascaris eggs were confirmed to be of human origin by archaeological evidence, it was not possible to pinpoint the exact species due to close genetic relationships among them. Despite this shortcoming, this is the first Ascaris ancient DNA (aDNA) report from a medieval Asian country and t...

Paleoparasitological studies using microscopy showed that Ascaris and Trichuris trichiura are the human intestinal parasites most found in archaeological sites. However, in pre-Columbian South American archaeological sites, Ascaris is rare. In this work we standardized a molecular methodology for Ascaris diagnosis directly from ancient DNA retrieved from coprolites. Using cythochrome b gene (14...

The sites of physical migration of adult Ascaris include a biliary duct, liver parenchyma, pancreas, peritoneum, thoracic cavity, lacrimal duct, Eustachian tube, fallopian tube, brain, and even a pulmonary artery.1 Areas that are not organically part of the Ascaris migration pattern are accessed through fistulization from sites that are normally infested with Ascaris. Only a limited number of r...

1. In a previous study, it was shown that the potency order for two arylamino-pyridazine derivatives, SR95531 and SR95103, was different in Ascaris suum when compared to vertebrate preparations. SR95531, the most potent analogue at the vertebrate GABAA receptor, was found to be very weak at antagonizing GABA responses in Ascaris, but SR95103, approximately 20 times less potent than SR95531 in v...

The typical locomotion of ascaris was found and studied by Kobayashi and Bando (1950) in a glass-tube of the appropriate diameter filled with Ringer or Bunge's solution. They also observed that santonin in vitro did not influence on survival-length of ascaris, but induced a spasmodic curling around the body of ascaris which seemed to be a kind of convulsion caused by the drug. It was supposed t...

the effect of a new anthelmintic compound, leavo-tetramisole, in the mass-treatment of several intestinal helminthes has been evaluated during a study undertaken among the population of the village of zavieh hajian, located about 10 km northwest of dezful, khuzestan.in the autumn of 1972, a total of 83 inhabitants, 65 of whom were simultaneously infected with ascaris, hookworm (ancylostoma) and...
